When John Hancock, president of the Second Continental Congress (a provisional government in the US during the American revolution) signed the US Declaration of Independence in 1776 he clearly wanted to make a statement. His signature, while almost certainly the most famous and important in US history, was also one of the biggest. It measures roughly 4.7 inches wide and 1.3 inches tall, and is the largest of the 56 names by some distance. If all 56 delegates had signed at Hancock’s scale, they would not have fitted on the page.

The reason behind the signature has been debated for years. The legend is that Hancock signed big so that King George III could read it without his spectacles, and stood up to say so. It is a lovely story. It has defiance, and a punchline but it is almost certainly made up. No account from the time records the remark. The earliest versions appeared in print decades later, usually bundled with the claim that Britain had put a price on Hancock’s head too.

So how did the man become the word? Copies of the Declaration spread through the new country, and Hancock’s was apparently the one name anybody could read from across the room. By the mid-1800s, ‘put your John Hancock here’ was everyday American English. Cowboys in the West then somehow turned it into ‘John Henry’, a variant that is still in dictionaries and that nobody has ever satisfactorily explained.

Should July 4th actually be Independence Day?

There is also uncertainty over the signing date of the document. The official record shows most of the 56 delegates signed the parchment on 2 August 1776, a month after Congress adopted the text, with the final names added later still. But Jefferson, Adams and Franklin all insisted, to the ends of their lives, that the Declaration was signed on 4th July. Jefferson went further, claiming a paper copy was signed that day and the parchment then signed again in August. If that paper copy ever existed, it has never been found, and fellow signer Thomas McKean flatly denied the 4th July signing ever happened.

Most historians side with McKean and the record. A few side with Jefferson, including one legal historian who argued in the 1980s that around 34 delegates really did sign on the day. Either way, three Founding Fathers and the man who printed the record could not agree on when the most famous document in American history was signed, which is quite the endorsement for keeping a good audit trail.

One more twist. There is a woman’s name on the Declaration of Independence, and it is the only name on it that was never signed. In January 1777, Congress ordered a new printing that would, for the first time, list the signers publicly, and gave the job to Mary Katharine Goddard, a Baltimore printer, publisher and postmaster, quite possibly the first woman employed by the United States government. At the bottom, where she usually put a discreet ‘M.K. Goddard’, she set her name in full - ‘Baltimore, in Maryland: Printed by Mary Katharine Goddard’. Putting your full, unmistakably female name on a treasonous document was its own act of defiance, arguably braver than Hancock’s, since she was not protected by a fortune. Only nine of her broadsides are known to survive.

Lost and found

The UK, meanwhile, has been sitting on its own copies. The UK National Archives at Kew holds three of the original broadsides printed in Philadelphia in 1776, and this year gained a fourth when a volunteer cataloguing Royal Navy papers found a copy printed in New Hampshire in July 1776. It had been seized on Christmas Eve that year when HMS Raisonable ran down an American ship off Portugal after a seven-hour chase.

The captured papers were shipped to Plymouth, then to Whitehall, where a naval clerk recorded the founding document of the United States as ‘another paper’. There it sat for almost 250 years. It has now been conserved and is going on display in the archives’ Revolution 250 exhibition, the only known copy of the Declaration ever taken by military action.

And one final thing. That painting by John Trumbull, called the Declaration of Independence which is hanging in the US Capitol rotunda (based on a smaller version currently held at Yale University Art Gallery), does not actually depict the signing of the document, as is sometimes suggested. It does in fact show the presentation of the draft declaration to Congress in June 1776.

So a story full of intrigue, complication and myth. The quote is invented, the date is disputed, the painting shows a different day, and the most defiant name on the document may belong to the printer. Strip all of that away and one fact is left standing: 250 years on, Americans still call a signature a John Hancock. Nobody has ever needed to fact-check that.

Why is it called a ‘wet’ signature?

The name refers to the ink being wet at the moment of signing. The term only came into common use after electronic signatures appeared. Before that, a wet signature was simply a signature. It is also called a wet ink signature, an ink signature or an original signature.

A wet signature is usually a handwritten name. It does not have to be. A handwritten initial, a mark such as an ‘X’, or an inked stamp or seal counts as a wet signature if it is applied physically to paper and identifies the signer.

Is a wet signature more legally valid than an electronic signature?

No. For most documents in the UK and US, a wet signature and an electronic signature carry the same legal weight.

In England and Wales, the Electronic Communications Act 2000 provides for the admissibility of electronic signatures, and the Law Commission confirmed in its 2019 report ‘Electronic Execution of Documents’ that an electronic signature is capable of executing a document wherever a signature is required, provided the signer intends to authenticate the document and any formalities are satisfied.

In the US, the ESIGN Act 2000 (15 U.S.C. § 7001) states that a signature cannot be denied legal effect solely because it is in electronic form. The Uniform Electronic Transactions Act (UETA) applies the same principle at state level and has been adopted by most states.

In the EU, Article 25(2) of the eIDAS Regulation (EU) No 910/2014 gives a qualified electronic signature the equivalent legal effect of a handwritten signature.

When is a wet signature still required?

It depends on the document type and jurisdiction.

In England and Wales, wills must be signed on paper by the testator in the presence of two witnesses under section 9 of the Wills Act 1837. Wills cannot be signed electronically.

A temporary provision allowing witnesses to be present by video link, introduced during the pandemic, expired on 31 January 2024 and was not renewed. The signature itself required wet ink throughout that period. Only the witnessing could be remote.

In the US, section 103 of the ESIGN Act (15 U.S.C. § 7003) excludes certain documents from its scope. These include wills and testamentary trusts, family law documents such as adoption and divorce papers, court orders, and notices of utility cancellation, eviction, foreclosure or insurance termination. For these documents, state law governs, and a wet signature is the standard method of execution.

Some organisations also require wet signatures as a matter of policy rather than law. A bank, insurer or counterparty is entitled to insist on ink even where legislation permits an electronic signature.

For a fuller breakdown of which documents fall outside e-signature legislation, see What documents cannot be signed electronically?.

Is a scanned signature a wet signature?

No. A scanned or photographed wet signature becomes a digital image. Once inserted into an electronic document, it functions as a form of electronic signature, not a wet signature. Where a wet signature is legally required, the original ink-on-paper document is what satisfies the requirement, not a scan of it.

Electronic signatures have the same legal standing as a handwritten signature for the vast majority of documents in the UK, US, and across the EU. You do not need to print, sign, and scan a document. You sign it digitally, and it is done.

The term covers a wide range of methods. A typed name at the bottom of an email is an electronic signature. So is a tick-box on a website, a finger-drawn squiggle on a touchscreen, or a secure certificate-backed signature generated by a signing platform. What is important is not what it looks like, it is whether you intended to sign.

Some types of electronic signature are more secure than others. A typed name is easy to dispute. A signature generated by a specialist platform creates an automatic record of who signed, when, and on which device, making it much harder to challenge. For everyday documents, a simple electronic signature is fine. For high-value contracts or regulated transactions, a more secure type gives you stronger protection.

BASIC QUESTIONS

Is an electronic signature legal?

Yes. Electronic signatures are legally recognised in the UK, across the EU, and in the US. In the UK, the law that makes them valid is the Electronic Communications Act 2000. In the US it is the Electronic Signatures in Global and National Commerce Act (the ESIGN Act, 2000). Across the EU it is the eIDAS Regulation. All three laws say that a signature cannot be rejected simply because it is electronic.

A small number of documents are exceptions. Wills in England and Wales, for example, still require a traditional wet-ink signature witnessed in person. But for the vast majority of everyday documents, an electronic signature is as valid as ink on paper.

What counts as an electronic signature?

More than most people expect. Any of the following count:

• Typing your name at the bottom of an email or document
• Clicking ‘I agree’ or ‘I accept’ on a website or app
• Drawing your signature on a touchscreen with your finger or a stylus
• Using an e-signature platform such as those that send a signing link by email
• A scanned image of your handwritten signature pasted into a document

The common thread is intent. You must be doing it deliberately, with the intention of signing. A signature is not valid just because your name appears on a document.

Is it safe to sign electronically?

For most documents, yes, and in many cases safer than paper. A signed paper document can be lost, altered, or disputed without a clear record of what happened. A good e-signature platform creates a timestamped record of who signed, from which device, and at what time. That record is often more reliable evidence than a piece of paper.

The level of security varies by method. A typed name provides minimal protection on its own. A signature generated by a dedicated platform provides a much stronger audit trail. For high-value or sensitive documents, it is worth using a platform rather than simply typing your name.

Do I need special software or an account?

Not for basic electronic signatures. Typing your name on a document or clicking a button requires no specialist software at all.

For a more secure signature with a proper audit trail, the kind most businesses use for contracts, you will typically need to use an e-signature platform. These are web-based services; in most cases the person signing does not need an account. They receive a link by email, click to open the document, and sign. The platform handles everything else.

Is an electronic signature the same as a digital signature?

No, though the terms are often confused. An electronic signature is the broad term. It covers any electronic method of signing. A digital signature is a specific, more secure type of electronic signature that uses cryptography to verify who signed and to detect whether the document has been changed afterwards.

Think of it this way: all digital signatures are electronic signatures, but most electronic signatures are not digital signatures. A typed name is an electronic signature. A certificate-backed signature generated by a secure platform is a digital signature. For a full explanation of the difference, see Electronic signature vs digital signature: what is the difference?.

GOING DEEPER

Are all electronic signatures equally strong?

No. There are three recognised tiers, defined in law across the UK and EU.

A simple electronic signature is any electronic indication of intent to sign, such as a typed name or a tick-box. It is legally valid but the easiest to dispute, because there is no automatic proof of who actually signed.

An advanced electronic signature is linked to the signer in a way that can be verified, and it detects any changes made to the document after signing. It is harder to dispute and is the standard offered by most reputable e-signature platforms.

A qualified electronic signature is the highest tier. It is backed by a certificate from a government-approved authority and carries the same legal weight as a handwritten signature in law. It cannot be rejected solely because it is electronic. It is typically used for high-value or regulated transactions.

For most everyday purposes, a simple or advanced electronic signature is sufficient. The tier matters most when a dispute is likely, or when a specific contract or regulator requires a higher standard.

When do I need a more secure type of electronic signature?

The higher the stakes, the more secure your signature should be. Consider using an advanced or qualified electronic signature when:

• The contract is high value and a dispute would be costly
• You are dealing with a regulated industry such as financial services or healthcare
• You are signing across borders within the EU, where qualified signatures carry a specific legal guarantee
• The other party requires it, or your organisation’s policy specifies it

For standard commercial contracts, employment agreements, and routine supplier documents, a simple or advanced electronic signature from a reputable platform is generally sufficient.

What documents cannot be signed electronically?

Most documents can be signed electronically. There are some exceptions where the law still requires a traditional handwritten signature.

In England and Wales, wills must be signed in wet ink in front of two witnesses in the same room. Electronic signatures are not valid for wills under the Wills Act 1837. Certain other documents, including statutory declarations, also require specific formalities that electronic signatures cannot satisfy.

Property deeds are a special case. They can be signed electronically, but only through specific methods accepted by HM Land Registry: either a Mercury signature (where you sign a printed page in ink, then scan it) or a Conveyancer-Certified Electronic Signature (where you sign through a platform in the physical presence of a witness). Your conveyancer will manage this process.

In the US, wills, court orders, and certain consumer protection notices are also excluded from the federal law that recognises electronic signatures.

Does an electronic signature need a witness?

For most documents, no. Everyday commercial contracts, employment agreements, and the majority of business documents do not require a witness, whether signed electronically or in ink.

Deeds are different. A deed, including a property transfer or a lasting power of attorney, must be signed in the physical presence of a witness. This applies whether you are signing electronically or in ink. The witness must be there in person; someone watching over a video call does not count.

If you are unsure whether a document needs a witness, check with a solicitor. The question is usually about the type of document, not the type of signature.

What happens if someone disputes an electronic signature?

The key question in a dispute is whether the signature is authentic. Did the right person sign, and is the document unchanged since they signed it?

A simple electronic signature such as a typed name relies on surrounding evidence: emails, timestamps, the context of the transaction. That evidence may be strong or weak depending on the situation.

A signature from a reputable e-signature platform comes with an audit trail: a record of the email address used, the IP address of the device, the time of signing, and each action taken. This makes it significantly harder to dispute. An advanced or qualified electronic signature goes further, using cryptography to tie the signature to the signer’s verified identity and to detect any change to the document after signing.

In UK courts, electronic signatures are admissible as evidence under the Electronic Communications Act 2000. Courts look at the totality of the evidence, not just the signature itself.

Does the law work differently in Scotland?

The core principle is the same: electronic signatures are legally valid. But Scotland has its own rules about formal documents.

For a document to be self-proving in Scotland, meaning a court presumes it is valid without needing additional evidence, it must carry a qualified electronic signature. An advanced electronic signature satisfies the authentication requirement but does not make a document self-proving. A simple electronic signature such as a typed name does neither for formal documents.

For everyday commercial contracts that do not require formal writing, any type of electronic signature works fine in Scotland, just as it does elsewhere in the UK.

What is the position in the US?

Federal law, in the shape of the ESIGN Act 2000, gives electronic signatures the same legal standing as handwritten signatures for most commercial and consumer documents. Forty-nine states have also adopted the Uniform Electronic Transactions Act (UETA), which covers transactions within individual states.

The ESIGN Act excludes a limited number of document types: wills, adoption and divorce documents, and certain consumer protection notices. For everything else, an electronic signature is fully valid.

Illinois and New York have their own state electronic signature laws rather than UETA, though the practical effect for most signers is similar. If you are signing a document with specific state-law implications, it is worth checking the rules for that state.

Before Brexit, the UK was part of the EU’s eIDAS system - a shared set of rules that gave electronic and digital signatures the same legal standing across all member states. A qualified digital signature issued by a UK trust service provider was automatically recognised in France, Germany, or any other EU country, and vice versa.

That automatic recognition ended when the UK left the EU. The UK kept the rules, writing them into UK law but it is no longer part of the EU’s mutual recognition network. The two systems now run in parallel, with similar rules but no formal connection between them.

For most organisations, this is not a day-to-day problem. A standard electronic signature, such as a typed name or a platform-generated signature, is legally valid on both sides of the Channel regardless of where the certificate comes from. The gap becomes relevant at the highest level of digital signature, where the formal guarantee of legal equivalence to a handwritten signature depends on which trusted list the certificate authority appears on.

Where things stand today

Basic Questions

Does Brexit mean my electronic signature is no longer valid in the EU?

No. Electronic signatures remain legally valid across the EU regardless of where you are based or where your signing platform is registered. The EU’s eIDAS rules say that an electronic signature cannot be rejected solely because it is electronic. That applies to signatures from UK-based signers as much as anyone else.

What changed after Brexit is the automatic mutual recognition of trust service providers at the highest tier. A qualified digital signature certificate issued by a UK provider is not automatically on the EU’s trusted list. That does not make the signature invalid, it means the formal legal guarantee of equivalence to a handwritten signature, which eIDAS provides across all EU member states, may not automatically apply.

What is the practical effect for most people?

For the vast majority of documents, such as commercial contracts, supplier agreements, and employment documents, there is no practical difference. Both sides accept electronic signatures, and neither system requires a qualified certificate for everyday transactions.

The gap matters most when you are signing a document that specifically requires the highest level of digital signature (a qualified electronic signature) because that guarantee of legal equivalence depends on the certificate being from a trusted list provider in the relevant jurisdiction. Organisations operating across both the UK and EU on regulated or high-value transactions are most likely to encounter this.

Are the rules the same in the UK and EU?

Broadly yes, but they are no longer linked. The UK kept the original eIDAS rules when it left the EU, so the three tiers of signature - simple, advanced, and qualified - are defined the same way on both sides. The key difference is that the UK and EU now maintain separate trusted lists of approved certificate authorities, and certificates from one list are not automatically recognised on the other.

The EU has also updated its rules since Brexit through eIDAS 2.0, which came into force in May 2024 and includes plans for a mandatory EU Digital Identity Wallet by end of 2026. The UK has not adopted these changes and is developing its own separate framework.

Going Deeper

What is the EU Digital Identity Wallet and how does it change things?

The EU Digital Identity Wallet is a new digital tool that every EU member state must make available to its citizens, residents, and businesses by the end of 2026. It is part of the updated eIDAS framework, known as eIDAS 2.0.

The wallet is a single app that lets people store and share their verified identity and other personal attributes, such as a driving licence, professional qualification, or bank account details, securely and selectively. Rather than handing over a full set of personal documents, a person can share only what is needed for a specific transaction.

For electronic signatures specifically, the wallet will allow EU citizens to use a qualified digital signature free of charge for personal use. Businesses that fall into certain categories, including large online platforms and banks, will be required to accept the wallet for verification and signing purposes.

The UK is not part of this system. UK citizens will not have access to an EU Digital Identity Wallet, and UK organisations are not subject to the acceptance obligations that apply to EU businesses. The UK is developing its own separate digital identity framework - the Digital Verification Services (DVS) trust framework under the Data (Use and Access) Act 2025 - but this is a different system with a different purpose and no formal connection to the EU wallet.

What is the UK’s Digital Verification Services framework?

The Digital Verification Services (DVS) trust framework is the UK’s approach to digital identity verification. It was established by Part 2 of the Data (Use and Access) Act 2025 and came into force in December 2025, overseen by the Office for Digital Identities and Attributes (OfDIA) within the government’s Department for Science, Innovation and Technology.

The DVS framework is a voluntary system. Providers of digital identity checking services can apply to be assessed against the government’s standards, and those that pass receive a trust mark and appear on a public register. This allows businesses and individuals to identify which digital identity services are reliable.

The DVS framework is about proving who you are digitally rather than about electronic signatures specifically. It is the UK’s equivalent in spirit, to parts of what the EU is doing with its wallet, but it covers a narrower scope and operates on a voluntary rather than mandatory basis. The two systems are not connected.

Could UK and EU signatures become mutually recognised in the future?

Possibly. The EU’s updated eIDAS framework includes a provision allowing the European Commission to assess whether trust frameworks in non-EU countries (known as third countries) are equivalent to the EU system. If a country’s framework is found to be equivalent, its trust service providers could be recognised within the EU’s system.

This has not happened for the UK, and there is no confirmed timeline for it to do so. The UK and EU are taking different approaches. The EU’s is mandatory and harmonised, the UK’s is voluntary and market-led. This is an area that is likely to develop over the coming years, particularly as the EU wallet rolls out and the UK DVS framework matures.

Does the industry I work in affect any of this?

Yes. The significance of the UK/EU gap varies considerably depending on sector. For a business that only signs commercial contracts, the gap is largely theoretical. Standard electronic signatures work on both sides without any issue.

For organisations in regulated industries, including financial services, healthcare and legal services, the picture is more complex. Some sectors have specific requirements for the type of signature or identity verification used, and these requirements may differ between the UK and EU. In financial services, for example, the EU’s new anti-money laundering rules require eIDAS-compliant digital identity for certain onboarding processes by 2027. A UK-based firm providing services into the EU needs to understand how those requirements apply to them.

Signatures.com is producing a series of industry-specific guides covering how these rules apply in different sectors. These will be published over the coming months.

What is a trusted list and why does it matter?

A trusted list is a government-maintained register of approved organisations, called trust service providers, that are authorised to issue qualified digital signature certificates. In the EU, each member state maintains its own trusted list, and together they form a network of mutually recognised providers. In the UK, the trusted list is maintained by the Information Commissioner’s Office (ICO). (Note: this is being renamed the Information Commission later this year).

The trusted list is important because a qualified digital signature (the highest legal tier) must be backed by a certificate from a provider on the relevant trusted list. A certificate from a UK-listed provider gives a signature its qualified status under UK law. A certificate from an EU-listed provider gives it qualified status across EU member states. A certificate from a provider on neither list does not qualify as a qualified electronic signature under either framework, even if the underlying technology is identical.

For organisations operating across both the UK and EU, using a provider that appears on both trusted lists (or using separate certificates for each jurisdiction) is the way to ensure the highest level of recognition on both sides.

The five methods at a glance

The table below gives the key details for each method.

Each method in detail

1. Typing your name

You type your name into a designated field. The platform or document may style it automatically in a cursive or signature-like font, or it may appear exactly as you typed it.

This is the simplest electronic signature. It is legally valid. A typed name is an electronic signature under UK, EU, and US law and requires no software beyond a keyboard.

The limitation is evidence. Anyone could type your name. If a dispute arises, proving that it was you who typed it relies on surrounding context: the email thread, the timestamp, the circumstances of the transaction. There is no automatic record embedded in the document itself.

Best used for: low-value internal documents, quick approvals, situations where both parties know each other and a dispute is unlikely.

2. Drawing your signature

You draw your signature directly onto the document using a mouse on a desktop, or your finger or a stylus on a touchscreen. The result looks more like a traditional signature than a typed name.

Like a typed name, a drawn signature is legally valid but provides limited evidence of identity on its own. The visual resemblance to a handwritten signature does not make it more secure. Anyone with access to your device or a screenshot of your signature could reproduce it.

Where a drawn signature has practical value is familiarity and feel. Many people find it more natural, and for touchscreen users it is often the most convenient method. On a phone or tablet it takes seconds.

Best used for: the same situations as a typed name, such as everyday documents where the identity of the signer is not likely to be challenged.

3. Uploading an image of your signature

You upload a photograph, scan, or digital image of your handwritten signature. The image is placed onto the document in the designated signature field.

This method is common when someone wants their electronic signature to look identical to their physical one, or when they have an existing signature image file they use regularly.

The security limitation is the same as for typed and drawn signatures. An image file can be copied and reused by anyone who has access to it. Placing the image on a document does not prove that the image’s owner authorised the signing.

Best used for: documents where appearance matters and the parties involved trust each other. Not recommended for high-value or regulated transactions.

4. Platform-generated signature

This is the method most businesses use for day-to-day contracts and agreements. You sign through a dedicated e-signature platform, which captures your signature (whether typed, drawn, or pre-set) and embeds it in the document alongside a detailed audit trail.

The audit trail is what makes this method significantly stronger than the first three. The platform records:

• The email address used to access the document
• The IP address and device used
• The date and time of each action
• A log of every step taken during the signing process

This record is stored separately from the document itself and can be produced as evidence if the signature is ever challenged. It does not prove identity in the way a government-issued ID does, but it makes a successful challenge significantly harder.

Most platform-generated signatures qualify as advanced electronic signatures under the eIDAS framework meaning they are uniquely linked to the signer and detect any change to the document after signing.

Best used for: the vast majority of business documents, such as employment contracts, supplier agreements, non-disclosure agreements, service contracts, and any commercial document where a record of the signing is important.

5. Digital signature

A digital signature uses cryptography to do two things that no other method can: prove conclusively who signed, and detect any change to the document after signing.

When you apply a digital signature, the software creates a unique fingerprint of the document at that exact moment and locks it to your verified identity using a certificate issued by a government-approved authority. If anyone changes even a single word after you sign, the fingerprint no longer matches and the signature shows as invalid.

At the highest level, the certificate requires verified identity checks before it is issued, similar to opening a bank account. A qualified digital signature carries exactly the same legal weight as a handwritten signature in UK and EU law.

Best used for: property transactions, high-value contracts, regulated documents, cross-border EU transactions, and any situation where the identity of the signer and the integrity of the document must be provable beyond reasonable doubt.

For more detail on how digital signatures work, see What is a digital signature?.

COMMON QUESTIONS

Does it matter which method I use?

For most everyday documents, no. All five methods are legally valid electronic signatures, and the law does not require you to use a more secure method than the situation demands.

It starts to matter when a dispute is likely, when a regulator requires a specific standard, or when the document is high value. In those cases, a platform-generated or digital signature gives you much stronger evidence than a typed name or drawn squiggle.

Are all five methods legally valid?

Yes. Under the Electronic Communications Act 2000 in the UK, the ESIGN Act 2000 in the US, and the eIDAS Regulation in the EU, none of these methods can be rejected solely because it is electronic. The law does not prescribe which method you must use for most documents.

The exception is a small number of documents, such as wills in England and Wales, for example. These still require a wet-ink signature. The method of electronic signing is irrelevant for those documents because electronic signing is not permitted at all. See What documents cannot be signed electronically?.

Which method is most commonly used?

For individual use, typing your name or drawing your signature is most common. For business use, platform-generated signatures are the standard. Most organisations that send contracts electronically use a dedicated e-signature platform that handles the audit trail automatically.

Digital signatures with certificates are most common in regulated industries, high-value transactions, and cross-border EU documents where a qualified signature is required.

Can I use different methods on the same document?

In most cases yes. Different parties to a contract can sign using different methods. There is no general rule requiring everyone to use the same approach.

The exception is property deeds submitted to HM Land Registry, where the signatory and their witness must both sign through the same platform using the same method. See What documents cannot be signed electronically? for more on deeds.

Is a drawn signature more legally valid than a typed one?

No. The visual similarity to a handwritten signature does not affect its legal standing. A typed name and a drawn signature are both simple electronic signatures. Neither is inherently more valid or more secure than the other.

What matters legally is intent to sign. What matters evidentially is the audit trail attached to the signature. A drawn signature with no platform audit trail is no stronger than a typed name in a dispute.

The question of whether a document can be signed electronically is really two separate questions. The first is whether electronic signing is permitted at all. The second is whether there are conditions attached, such as the need for a witness, or a particular type of signature.

For most documents, the answer to both questions is straightforward. For a smaller group, mainly formal legal documents and property transactions, the conditions are important and vary depending on where you are.

The table below covers the most commonly asked-about document types. The questions that follow explain the detail behind the most important categories.

Document types at a glance

Green: electronic signatures permitted without restriction. Red: not permitted electronically. Amber: permitted but specific conditions apply.

Basic Questions

Can I sign a will electronically?

No, not in the UK or the US. A will requires a wet-ink signature witnessed in person by two people who are both present at the same time. This is a long-standing legal requirement and it applies regardless of how straightforward the will is.

In England and Wales this rule comes from the Wills Act 1837. A temporary exception was introduced during the Covid-19 pandemic allowing wills to be witnessed by video call, but that exception expired in January 2022 and no longer applies. In Scotland the position is the same. In the US, wills are explicitly excluded from the federal law that permits electronic signatures.

If you sign a will electronically it will not be valid. Your estate could be treated as if you had no will at all.

Can I sign a property deed electronically?

Yes, but only in specific ways. A deed, including a property transfer, a mortgage, or a lease, must be signed in the physical presence of a witness. That requirement applies whether you sign electronically or in ink. Remote or video witnessing is not accepted.

In England and Wales, HM Land Registry accepts two methods. A Mercury signature is where you print the document, sign it in ink in front of a witness, then scan it. A Conveyancer-Certified Electronic Signature (CCES) is where you sign through a platform, again in the physical presence of a witness, with your conveyancer certifying the process was followed correctly. Your conveyancer will manage whichever method applies to your transaction.

A simple electronic signature, such as a typed name, is not sufficient for a deed, even though it is legally valid for most other documents.

Can I sign an employment contract electronically?

Yes. Employment contracts can be signed electronically in the UK and the US without any restrictions. There is no requirement for a witness, a specific type of signature, or a particular platform. A typed name, a platform-generated signature, or any other electronic method is valid.

Some employment documents, such as a settlement agreement in the UK, require the employee to have received independent legal advice before signing, but this is about the advice requirement, not the signature. The signature itself can still be electronic.

Can I sign a power of attorney electronically?

It depends on the type. An ordinary power of attorney, used for a specific transaction or period, can be signed electronically in most cases.

A lasting power of attorney (LPA) in England and Wales is more complex. An LPA must be signed in the presence of a witness, and the prescribed form set out by the Office of the Public Guardian must be followed precisely. The form itself has specific signature and witnessing requirements that limit how electronic signing can be used in practice. If you are setting up an LPA, your solicitor will advise on the current accepted methods.

In Scotland, the equivalent document is a continuing or welfare power of attorney. Similar formal requirements apply.

Can I sign a tenancy agreement electronically?

Yes. Tenancy agreements, including assured shorthold tenancies in England and Wales, can be signed electronically by both landlord and tenant. There is no legal requirement for a wet-ink signature or a witness for a standard tenancy agreement.

Some landlords or letting agents may have their own policies requiring a physical signature, but this is a preference, not a legal requirement. If the tenancy agreement is being used as the basis for a deed, for example a lease of more than three years, which must be executed as a deed, the deed rules apply instead.

GOING DEEPER

What exactly is a deed and why are the rules different?

A deed is a specific type of legal document that transfers a right, creates an obligation, or makes a solemn promise. The most common examples are property transfers, mortgages, leases of more than three years, lasting powers of attorney, and guarantees.

Deeds are treated differently because the law has always required more formality for them. In England and Wales, a deed must be signed in the presence of a witness, someone who is physically there and who also signs to confirm they witnessed the signing. This requirement comes from the Law of Property (Miscellaneous Provisions) Act 1989.

The key point is that this witness requirement applies to the act of signing, not to the type of signature. You can sign a deed electronically provided the witness is physically present. What you cannot do is have the witness watch over a video call, or sign separately without being present at the moment you sign.

Does a document need a witness to be signed electronically?

Most documents do not need a witness at all, whether signed electronically or in ink. Everyday commercial contracts, employment agreements, supplier agreements, and most other business documents have no witness requirement.

The exceptions are documents that must be executed as deeds. These require a witness who is physically present. The witness must sign the document themselves to confirm they were there. They cannot be a party to the document. They must be an independent third party.

If you are unsure whether a document needs a witness, the question to ask is whether it is a deed. If it is not a deed, it almost certainly does not need one.

What documents are excluded in the US?

The federal ESIGN Act 2000 explicitly excludes a specific list of document types from the general rule that electronic signatures are valid. These are:

• Wills, codicils, and testamentary trusts
• Adoption and divorce documents
• Court orders and official court documents
• Notices of cancellation or termination of utility services
• Notices of default, foreclosure, eviction, or repossession relating to a primary residence
• Notices of cancellation of health or life insurance
• Notices relating to hazardous materials or substances

Beyond these federal exclusions, individual states may impose additional requirements. Real estate transactions in particular vary significantly between states, and some require notarisation which has its own rules. If you are signing a document with specific state-law implications it is worth checking the rules for that state.

What is the position in Scotland?

Scotland has the same broad position as England and Wales. Most documents can be signed electronically, and the exceptions follow a similar pattern. The detail differs in two ways.

First, the formal requirements for Scottish deeds are set out in the Requirements of Writing (Scotland) Act 1995. For a document to be self-proving in Scotland, meaning a court presumes it is valid without further evidence, it must carry a qualified electronic signature. An advanced electronic signature is sufficient for authentication but does not make a document self-proving.

Second, wills in Scotland require a wet-ink signature. The formal requirements for Scottish wills have not been relaxed in the way that the temporary Covid exception briefly relaxed them in England and Wales.

Can the rules change? Have they changed recently?

Yes, and they have. The clearest recent example is will-signing in England and Wales. During the Covid-19 pandemic the government temporarily changed the law to allow wills to be witnessed by video call. That change applied to deaths between January 2020 and January 2022. It has since expired and the original rules now apply again.

HM Land Registry has also updated its practice over time. The Conveyancer-Certified Electronic Signature process was formalised in Practice Guide 82, first published in March 2022 and updated in July 2025. The terminology changed from ‘witnessed electronic signature’ to ‘conveyancer-certified electronic signature’, and the process was refined.

The EU’s digital identity wallet (being rolled out by end of 2026) will change some of the practical landscape for EU-based signers, particularly around identity verification for regulated documents. This does not apply to the UK. Signatures.com will update this page as the rules develop.

What happens if I sign a document electronically when I should not have?

It depends on the document and the circumstances. For a will, the consequences are serious: an electronically signed will is not valid, and if there is no valid earlier will, your estate could be distributed as if you had died without one. That may be very different from your wishes.

For a deed, an invalid signature could mean the document is unenforceable. In a property transaction this could cause the transfer not to complete, or create a dispute about whether ownership has passed. The practical consequences depend on what the parties have done in reliance on the document.

For most other documents, the consequences are likely to be less severe. The document may be treated as a binding agreement even without a technically valid signature, depending on what the parties intended and how they have acted. But this is not something to rely on. If you are in doubt about whether a document requires a wet-ink signature, take advice before signing.

Start here: three questions before you look at any platform

These three questions determine your minimum requirements. Get them wrong and you may choose a platform that cannot legally serve your needs.

1. What type of documents will you be signing?

This is the most important question. Different documents require different types of signature, and not all platforms support all types.

• Everyday commercial contracts, employment agreements, and supplier documents can be signed with a standard platform-generated signature. Most platforms support this.
• Regulated transactions or cross-border EU documents that specify an advanced or qualified electronic signature require a platform that supports those tiers and holds certificates from a UK or EU trusted list provider. Not all platforms do.
• Property deeds in England and Wales require a specific process accepted by HM Land Registry. This is either a Mercury signature or a Conveyancer-Certified Electronic Signature (CCES). Only platforms that support HMLR’s CCES process are suitable. Your conveyancer will advise.
• Documents that cannot be signed electronically at all, such as wills and statutory declarations, should not be routed through any e-signature platform. See What documents cannot be signed electronically?

2. What signature tier do you need?

Platforms vary significantly in the tier of electronic signature they support. Some offer only simple electronic signatures. Others support advanced signatures with full audit trails. A smaller number support qualified electronic signatures backed by certificates from a government-approved trust service provider.

If your documents require an advanced or qualified signature because of their value, their regulatory context, or because a counterparty requires it, confirm that the platform supports that tier before trialling it. A platform that only supports simple signatures cannot be upgraded by changing a setting.

For a full explanation of the three tiers and when each is required, see Types of electronic signature: which method should you use?.

3. Do you operate across the UK and EU?

If you sign documents with counterparties in EU member states and need the highest legal certainty in both jurisdictions, you may need a platform whose certificate provider appears on both the UK trusted list and an EU member state’s trusted list. UK and EU trusted lists are separate since Brexit and certificates from one are not automatically recognised on the other.

For most everyday commercial contracts this is not a practical issue. For regulated transactions however, such as in financial services, certain professional services and public procurement, it may be essential. See Do UK electronic signatures work in the EU? for the full picture.

Nine criteria for evaluating any platform

Once you have answered the three questions above, use these criteria to assess each platform you trial.

Evaluation checklist

Use this when trialling platforms. A platform should meet all items marked as essential before you commit.

Also consider

How to trial a platform properly

Most platforms offer a free trial of two to four weeks. The way you use that trial determines whether it tells you anything useful. Five things to do before the trial ends:

• Trial with your most common document type, not a test document. A dummy NDA tells you nothing useful. Your standard employment contract or supplier agreement will.
• Involve a real signer who is not from your IT team. If they cannot work out how to sign without assistance, your clients will not either.
• Send yourself a document and review the audit trail in full before the trial ends. Check it records everything on the essential checklist above.
• Test the support channel during the trial, not after you have committed. Raise a question and see how long it takes to get a useful answer.
• Check the cancellation and data export process before you sign up, not when you want to leave. Confirm you can export all signed documents and audit trails in a usable format.

Each question above has a dedicated in-depth guide. Browse the full series:

The question of whether an electronic signature is legally binding is really a question about intent. The law does not require a specific technology or a specific appearance. What it requires is that the person signing intended to sign. Clicking a button, typing a name, or drawing a squiggle on a screen all demonstrate that intent, provided the context makes clear what the person was agreeing to.

The strength of an electronic signature varies by method. A typed name on an email is legally valid but easier to dispute than a signature generated through a dedicated platform with a full audit trail. A qualified digital signature, backed by a certificate from a government-approved authority, is the hardest of all to challenge and carries an explicit legal guarantee of equivalence to a handwritten signature. But all of them are binding.

The exceptions are important. A handful of document types, such as wills, statutory declarations, and a small number of others, still require a wet-ink signature under specific legislation. For those documents, the general rule does not apply. Outside those exceptions, electronic signatures are fully enforceable.

The legal position by jurisdiction

The core rule is the same in all three jurisdictions: electronic signatures are valid. The detail differs.

Basic Questions

What makes an electronic signature legally binding?

Two things: intent and context. The person signing must intend to sign, to indicate their agreement or authorisation, and it must be clear from the context what they are agreeing to. A signature applied through a dedicated signing platform satisfies both conditions easily: the signer follows a clear process, is shown the document before signing, and confirms their action deliberately.

A typed name at the bottom of an email can also satisfy both conditions, though it is easier to dispute. The intent is demonstrated by the act of typing; the context is the email exchange and the document attached. Courts look at the full picture, not just the signature itself.

Does it matter which type of electronic signature I use?

For most documents, no. Any electronic signature is binding. What differs is how easy it is to challenge. A simple electronic signature such as a typed name is valid but relies on surrounding evidence if disputed. A platform-generated signature with an audit trail is significantly harder to challenge. A qualified digital signature provides the strongest possible evidence and carries an explicit legal guarantee.

The type starts to matter when a specific standard is required - for example, certain regulated transactions or cross-border EU documents where a qualified electronic signature is specified. For those, a simple typed name would not be sufficient, even though it is technically binding for most other purposes.

Can someone refuse to accept an electronic signature?

Not on legal grounds alone in the UK, US, or EU. The law in all three jurisdictions says explicitly that a signature cannot be refused solely because it is electronic. If someone refuses an electronic signature, they must have a reason beyond the fact that it is not handwritten.

Legitimate reasons to require a different method include: the document type is one of the specific statutory exceptions; a contract between the parties specifies a particular signing method; or a regulator has prescribed a specific standard for that transaction type. Habit or preference is not a legal reason, though in practice you may need to comply to complete the transaction.

Is an electronic signature binding even without a witness?

For most documents, yes. The vast majority of contracts and agreements have no witnessing requirement, whether signed electronically or in ink. No witness is needed for employment contracts, commercial agreements, supplier contracts, or most consumer documents.

The exception is deeds. This includes property transfers and lasting powers of attorney. Both require a witness to be physically present. That witnessing requirement applies regardless of whether the signature is electronic or handwritten. Outside of deeds, witnessing is not a condition of legal validity.

Going Deeper

What happens if someone disputes an electronic signature?

The starting point is that the signature is presumed valid. The person challenging it must produce evidence that it was not genuinely made by the person named, or that the document was altered after signing.

A simple electronic signature - a typed name - is challenged by arguing that the named person did not type it. The response relies on surrounding evidence: email records, timestamps, communications between the parties. A platform-generated signature adds a structured audit trail that is harder to unpick. A qualified digital signature is the most robust: any change to the document after signing invalidates it automatically, and the certificate ties the signature to a verified identity.

In UK courts, electronic signatures are admissible as evidence under the Electronic Communications Act 2000. Courts have consistently treated well-documented electronic signatures as binding. The Law Commission confirmed in its 2019 report (Law Com No 386) that there is no legal barrier to electronic signatures being used to execute most documents, including deeds.

Are electronic signatures binding for consumer contracts?

Yes. Consumer contracts for goods, services, subscriptions, and most other everyday agreements can be signed electronically without restriction in the UK, US, and EU. Clicking ‘I agree’ on a website or app is an electronic signature and creates a binding contract, provided the terms were clearly presented before the click.

In the US, the ESIGN Act specifically addresses consumer contracts and sets out requirements for electronic consent to be valid: the consumer must affirmatively consent to electronic records, must be able to withdraw that consent, and must receive a clear statement of their right to receive paper records. These requirements apply to the delivery of documents rather than to the signature itself, but they are relevant for businesses sending contracts electronically to consumers.

Does the law differ for business-to-business contracts?

The legal position is the same. Electronic signatures are binding. However, the practical considerations differ. Business contracts are more likely to be high value, more likely to be disputed, and more likely to require a specific standard of signature as a matter of commercial practice or contractual specification.

Many businesses now specify in their standard terms what signing method is acceptable. If a contract says it must be signed by a qualified electronic signature or by wet ink, then those terms govern the transaction, not the general rule. A business that signs electronically where the contract specified wet ink may find the signature disputed, even though electronic signatures are generally valid.

What about electronic signatures on contracts governed by foreign law?

If a contract specifies that it is governed by the law of a particular country, the validity of the electronic signature may be assessed under that country’s rules. Most major jurisdictions now recognise electronic signatures, but the specific requirements vary.

For UK businesses signing contracts governed by EU law, the eIDAS framework applies. For contracts governed by US state law, the relevant state’s version of UETA or the ESIGN Act applies. For contracts governed by the law of jurisdictions outside the UK, US, and EU, separate advice is needed. The principle - electronic signatures are generally valid - is widely accepted internationally, but the specifics differ.

The term ‘wet signature’ refers to the traditional act of signing in ink. The name comes from the time it takes for ink to dry. It has no special legal status beyond its long history as the default way to sign. The law does not treat a wet signature as inherently more valid than an electronic one for most documents.

The UK’s Electronic Communications Act 2000, the EU’s eIDAS Regulation, and the US ESIGN Act 2000 all establish that an electronic signature cannot be refused simply because it is not handwritten. Many organisations still ask for wet signatures out of habit, internal policy, or because their systems have not caught up with the law.

When is a wet signature actually required?

Red: wet ink required by law. Green: electronic signature is valid. Amber: depends on who is asking, not the law.

What does ‘wet signature’ actually mean?

It means a handwritten signature applied in ink, directly onto a physical document. The term ‘wet’ refers to wet ink, as opposed to a digital mark applied electronically. Beyond that description, it has no formal legal definition in UK or US law.

Is a wet signature more legally valid than an electronic one?

No, for most documents. The Electronic Communications Act 2000 in the UK, the ESIGN Act 2000 in the US, and the eIDAS Regulation in the EU all establish that an electronic signature has the same legal standing as a handwritten one. Neither is superior to the other by law.

The exceptions are the small number of document types where wet ink is specifically required by statute. This includes wills in England and Wales. For everything else, the two methods are equivalent.

Someone is asking me for a wet signature. Do I have to comply?

It depends on whether the request reflects a legal requirement or an organisational preference. If it is a legal requirement, such as a will or a statutory declaration, then yes. If it is a bank, employer, or landlord asking out of policy or habit, there is no legal obligation to provide one, though in practice you may need to comply to complete the transaction.

If you are unsure, ask the person making the request to confirm whether a wet signature is legally required or whether an electronic signature would be accepted. Many organisations will accept electronic signatures once asked directly.

Can I convert a wet signature into an electronic one by scanning it?

Scanning or photographing your wet signature and inserting the image into a document creates an electronic signature, or more specifically, an uploaded image signature. It is legally valid for most documents. It is not, however, a wet signature. The original physical act of signing in ink on a specific document is what makes something a wet signature, and a digital copy of that act does not replicate it.

For documents that genuinely require a wet signature, a scanned image does not satisfy the requirement. You need to sign the physical document in ink and present that same document.

Is a wet signature more secure than an electronic one?

Not necessarily. A handwritten signature on paper can be forged, copied, or attached to the wrong document without detection. An advanced or digital electronic signature, by contrast, automatically detects any change to the document after signing and creates a timestamped audit trail of the signing event.

For high-value or disputed transactions, a well-implemented electronic signature is often harder to challenge than a wet one.

Related guides

Most electronic signatures you encounter in everyday life are not qualified electronic signatures. A typed name, a drawn squiggle, or a platform-generated signature are all valid electronic signatures, but they sit at a lower tier. A qualified electronic signature requires specific identity verification, a government-approved certificate, and certified signing technology. That combination is what gives it its legal guarantee.

For most business documents, a lower tier is perfectly sufficient. The qualified electronic signature becomes relevant when the stakes are high enough that you need the strongest possible legal assurance, or when a specific regulation, jurisdiction, or transaction type requires it.

The three tiers of electronic signature

A qualified electronic signature sits at the top of a three-tier system defined in UK and EU law.

Basic Questions

What makes a qualified electronic signature different from a normal one?

Three things that work together. First, a verified identity: getting a qualified certificate requires you to prove who you are. Typically this is through a government-issued ID check, similar to opening a bank account. Second, a qualified certificate: the certificate must be issued by a trust service provider on the government-maintained trusted list in the UK or EU. Third, a qualified signature creation device: the signature must be created using hardware or software certified to a specific security standard, which ensures the private key used to create the signature cannot be extracted or misused.

It is the combination of all three that makes a QES carry the force of law. A signature that meets only one or two of these requirements is an advanced electronic signature, not a qualified one.

What is the legal effect of a qualified electronic signature?

In the UK and across the EU, a qualified electronic signature has exactly the same legal effect as a handwritten signature. It cannot be refused solely on the grounds that it is electronic, and it is admissible as evidence in legal proceedings without further proof of authenticity. This guarantee is set out in Article 25(2) of the eIDAS Regulation and applies in retained form in the UK under SI 2016/696.

In the US, the ESIGN Act does not use the same tier system, but a digital signature backed by a certificate from a recognised authority carries the strongest evidentiary weight available under US law.

When do I actually need a qualified electronic signature?

For most everyday documents, including commercial contracts, employment agreements and supplier terms, you do not need one. A standard platform-generated signature (an advanced electronic signature) is sufficient and much quicker to obtain.

A qualified electronic signature is typically needed when:

• A regulation specifically requires it. Some EU financial services and public sector processes specify QES
• You are signing a cross-border EU document where the highest legal certainty is required
• Your organisation’s policy or a contract requires it for high-value transactions
• You are signing a property deed through HM Land Registry’s QES pilot scheme in England and Wales

If you are unsure whether a specific document requires a QES, the obligation usually comes from the regulation or contract governing that transaction, not from the general law of electronic signatures.

How do I get a qualified electronic signature?

You need a qualified certificate from a trust service provider listed on the relevant trusted list. The UK trusted list is maintained by the ICO. Each EU member state has its own trusted list. Getting a qualified certificate requires a verified identity check. Depending on the provider, this may be done in person, by video call, or through a certified digital identity service.

Once you have a certificate, you apply it using a qualified signature creation device. This may be a hardware token (a USB device), a certified software application, or a signing platform that supports QES. The signing platform or your IT team will guide you through the process. Individual users seeking a QES for personal use may be able to obtain one through national identity schemes, and under eIDAS 2.0 EU citizens will be able to use a qualified signature free of charge through the EU Digital Identity Wallet by end of 2026.

Going Deeper

What is a trust service provider?

A trust service provider (TSP) is an organisation authorised by a government to issue qualified certificates and provide other digital trust services. To be authorised, a TSP must meet rigorous security, technical, and operational standards set by the relevant regulatory body.

In the UK, the list of authorised trust service providers is maintained by the Information Commissioner’s Office (ICO), which is being renamed the Information Commission in late 2026. In the EU, each member state maintains its own national trusted list, and the European Commission publishes a combined list of all EU trusted lists - called unsurprisingly List of Trusted Lists (LOTL). A certificate from a provider on either list qualifies for the legal guarantee associated with a QES in that jurisdiction. UK and EU trusted lists are separate and not mutually recognised since Brexit.

What is a qualified signature creation device?

A qualified signature creation device (QSCD) is hardware or software certified to generate and protect private keys to a standard that prevents them being copied, extracted, or used by anyone other than the rightful owner. This is what ensures that only you can apply your qualified electronic signature.

In practice, a QSCD is often a hardware token, often a small USB device that stores your private key securely, or a certified cloud-based signing service where the key is protected by equivalent hardware in a data centre. The certification standard is set by ETSI (the European Telecommunications Standards Institute). You do not need to manage the technical details yourself. Your trust service provider will supply a QSCD as part of the certificate issuance process, or direct you to a compatible one.

Is a qualified electronic signature the same as a digital signature?

All qualified electronic signatures are digital signatures. They use cryptography to verify identity and detect tampering. But not all digital signatures are qualified electronic signatures. A digital signature backed by a certificate from a provider that is not on the UK or EU trusted list, or created without a qualified signature creation device, does not meet the QES standard.

This is an important distinction. A QES carries the statutory guarantee of equivalence to a handwritten signature. A non-qualified digital signature does not carry that same guarantee, though it may still be legally valid and evidentially strong for most purposes. See What is a digital signature? for a full explanation.

Does a qualified electronic signature work across borders?

Within the EU, yes. A QES issued by a trust service provider on any EU member state’s trusted list is recognised across all EU member states. That mutual recognition is one of the core purposes of the eIDAS Regulation.

Between the UK and EU, the position is more complex since Brexit. A QES issued by a UK trust service provider is not automatically recognised within the EU’s mutual recognition framework, and vice versa. Organisations operating across both jurisdictions may need certificates from providers on both trusted lists, or should check with their legal advisers whether a specific transaction requires recognition in both jurisdictions. See Do UK electronic signatures work in the EU? for the full picture.

What is changing with eIDAS 2.0?

The EU updated its eIDAS framework in 2024 with Regulation (EU) 2024/1183 (eIDAS 2.0). The definition and legal effect of a qualified electronic signature remain unchanged. What eIDAS 2.0 adds is the EU Digital Identity Wallet, which every EU member state must make available to citizens by end of 2026. The wallet will allow EU citizens to apply a qualified electronic signature free of charge for personal non-professional use.

This does not apply to the UK. The UK retains the original eIDAS framework as written into UK law after Brexit, and is developing its own separate digital identity framework under the Data (Use and Access) Act 2025. UK citizens will not have access to the EU Digital Identity Wallet.

The signing process: step by step

This is what typically happens when you are asked to sign a document electronically.

If you are sending a document for others to sign

The steps above describe the experience of being asked to sign. If you are the one sending a document, the process from your side typically looks like this.

1. Upload your document to the platform. This is usually a PDF or Word file.
2. Add the names and email addresses of the people who need to sign.
3. Mark where each person needs to sign, initial, or provide information.
4. Send the document. Each signer receives a notification by email.
5. Monitor the progress. Most platforms show you who has signed and who is still to sign.
6. Receive the completed document once all parties have signed.

Most platforms also allow you to set a signing order. For example, person A must sign before person B is notified. You should also be able to set a deadline after which the signing link expires.

Common Questions

Do I need to create an account to sign?

Usually not. Most platforms allow you to sign a document as a guest by following the link in the email you receive. You may need to confirm your email address or enter a verification code, but creating a full account is typically optional for the person signing.

If you are sending documents regularly, you will need an account with a platform. Most offer a free tier for low volumes.

Is my signature legally binding?

Yes. An electronic signature applied through this process is legally valid for the vast majority of documents in the UK, US, and EU. The law does not require a handwritten signature for most commercial and consumer documents. What matters is that you intended to sign - and clicking through a signing process is a clear demonstration of that intent.

A small number of documents, such as wills in England and Wales, for example, still require a wet-ink signature. See What documents cannot be signed electronically? for a full list.

What if I make a mistake while signing?

Before you submit, you can usually clear your signature and start again. Look for a ‘Clear’, ‘Redo’, or ‘Edit’ option near the signature field. Once you have submitted, the process depends on the platform. Some platforms allow the sender to cancel and resend, others require a new document to be prepared.

If you have already submitted and realise you have signed something incorrectly or in error, contact the sender as soon as possible.

Can I sign on a mobile phone or tablet?

Yes. Most signing platforms work in a mobile browser without any app download needed. The experience is optimised for touchscreens. Drawing your signature with your finger is often easier on a phone than on a desktop. If the platform has an app, that will usually give the smoothest experience on mobile.

What happens if I do not sign in time?

If the sender has set a deadline, your signing link may expire and show as invalid. In that case, contact the sender and ask them to resend the document or extend the deadline. Most platforms allow the sender to do this without starting the process again from scratch.

How do I know the document has not been changed after I signed?

If the document was signed through a platform that uses advanced or digital signing technology, any change to the document after signing will automatically invalidate the signature. When you or anyone else opens the completed PDF, it will show whether the signatures are valid and whether the document is unchanged.

Adobe Acrobat Reader - which is free - verifies digital signatures automatically and displays the result clearly. A green tick means the signature is valid and the document is unchanged.

Note: The process below describes how sending works on a typical e-signature platform. The steps and screen layout will vary between platforms, but the underlying process is the same. Signatures.com does not endorse or recommend any specific platform.

Before you send: what to prepare

Getting these things right before you upload the document saves time and avoids the need to cancel and resend.

Sending the document: step by step

If you also need to sign the document

If you are both sending the document and signing it yourself, most platforms offer two options.

Sign first, then send. You sign the document before sending it out. The other signers see your signature already in place when they open it. This is common for contracts where you, as the sender, are confirming the terms before the other party signs.

Sign as one of the signers. Add yourself as a signer at the relevant position in the signing order. You will receive the same signing link as the other signers and complete the process in the same way.

Check your platform’s guidance on which option to use, as the naming and workflow varies.

What can go wrong. And how to fix it

The signer says they have not received the email

Ask them to check their spam or junk folder first. Signing request emails are sometimes filtered. If it is not there, verify the email address you used and resend the notification from the platform dashboard. Do not send a new document from scratch unless the original has an error.

The signer cannot open the document

Most signing platforms work in a browser without any software installation. If the signer is having difficulty, ask them to try a different browser or device. If the problem persists, contact the platform’s support team.

A signer declines to sign

Most platforms notify you if a signer declines and may give them the option to leave a reason. If a signer declines, the document is not complete. Contact the signer directly to understand their concern before restarting the process.

The signing link has expired

If a deadline was set and the signer did not sign in time, the link will have expired. Most platforms allow you to extend the deadline or resend the link from the dashboard without starting again from scratch.

You need to change the document after sending

You cannot edit a document once it has been sent for signing without cancelling the current request. If a change is needed, cancel the existing envelope, make the correction, and send again. Notify any signers who have already signed that a revised version is coming.

Pre-send checklist

Use this before clicking send.

Common Questions

Does the recipient need an account to sign?

Usually not. Most e-signature platforms allow recipients to sign as a guest by following the link in the email they receive. They may need to confirm their email address or enter a verification code, but creating a full account is typically optional for signers.

If the document requires a higher level of identity verification, for example, a qualified electronic signature, the signer may need to go through an identity check process before signing. This is less common for everyday documents.

Can I send to multiple signers at the same time?

Yes. Most platforms support multi-party signing. You can choose to notify all signers simultaneously, so they can sign in any order, or set a sequential order so each signer is only notified once the previous person has signed.

Sequential signing is common for employment contracts (employee signs, then employer countersigns), sales agreements, and any document where the parties sign in a defined order. Simultaneous signing is common for agreements between equals where order does not matter.

Is there a limit on the size of document I can send?

File size limits vary between platforms. Most support documents up to 25MB, which covers the vast majority of contracts and agreements. If your document is very large, for example, a lengthy agreement with many attachments, check the platform’s limit before uploading. Compressing the PDF or splitting attachments into separate documents usually resolves size issues.

Can I send a document that is not in English?

Yes. The document language does not affect the e-signature process. The platform interface may be in a different language from the document itself. What matters legally is that the signer understood what they were signing, which is a question of contract law, not electronic signature law. If a document is in a language the signer does not read, that is a separate issue to resolve before sending.

How long should I keep the signed document and audit trail?

Keep signed documents for at least as long as the contract or relationship they relate to, plus a reasonable period after it ends in case of a dispute. For most commercial contracts, six years is a common benchmark in the UK. This reflects the standard limitation period for contract claims under the Limitation Act 1980. For employment documents, HMRC recommends keeping payroll records for a minimum of three years from the end of the tax year.

Keep the audit trail with the signed document. If a dispute arises, the audit trail is evidence of when and how the document was signed. Store both in a secure location with appropriate access controls.

What if the other party wants a wet signature instead?

Ask them whether a wet signature is a legal requirement or a preference. For most commercial documents, an electronic signature is as legally valid as a wet-ink one. If they insist on wet ink for reasons of preference or internal policy, you will need to accommodate that but it is worth clarifying, as many requests for wet signatures are habit rather than legal necessity.

See Do I need a wet signature, or will an electronic one do? for a full breakdown of when wet ink is genuinely required.

When you sign a document through an e-signature platform, the platform does two things simultaneously. Firstly, it captures your signature and applies it to the document. Secondly, it records every step of the process in a log. That log, also referred to as the audit trail, is kept by the platform independently of the document itself.

If someone claims they did not sign, did not receive the document, or did not understand what they were agreeing to, the audit trail is the evidence that either supports or undermines that claim.

What an audit trail typically records

The exact content varies between platforms, but a well-structured audit trail will include the following.

Does every electronic signature come with an audit trail?

No. The three most basic signing methods (typing your name, drawing a squiggle, or uploading an image of your signature) produce no automatic audit trail. If you type your name at the bottom of an email, there is no platform recording the time, device, or steps involved.

An audit trail is generated by a dedicated e-signature platform. When you use a platform to send or sign a document, the platform records the process automatically. The audit trail is then attached to or stored alongside the completed document. This is one of the main practical reasons to use a platform rather than a simple typed name for business documents.

Where is the audit trail stored?

The platform stores the audit trail on its own servers, separately from the signed document. When the signing process is complete, most platforms attach a summary certificate to the PDF or make the full audit trail available to download. Keep both the signed document and the audit trail together in a secure location.

If you stop using a platform or close your account, check what happens to your stored audit trails. Most platforms retain records for a defined period after account closure, but the terms vary. If long-term retention matters for your documents, download and store the audit trail independently.

Can an audit trail be used as evidence in court?

Yes. In UK courts, electronic signatures are admissible as evidence under the Electronic Communications Act 2000, and the audit trail is the supporting record that establishes how and when the signature was applied. Courts consider the totality of the evidence. The audit trail is not automatically conclusive, but a detailed, timestamped record from a reputable platform carries significant weight.

In the US, the ESIGN Act 2000 and state UETA laws establish that electronic signatures have the same legal standing as handwritten ones. Courts have consistently held that a well-documented audit trail satisfies the evidentiary requirements for enforcing electronically signed contracts.

Is an audit trail the same as a digital signature?

No, though they often appear together. An audit trail is a record of the signing process. Who did what and when. A digital signature is a cryptographic mechanism that verifies identity and detects tampering. A platform-generated signature typically provides both: an audit trail of the process and a cryptographic hash of the document at the point of signing.

A simple electronic signature has neither. It has no audit trail and no cryptographic protection. The document could be altered after signing with no automatic detection.

How long should I keep an audit trail?

Keep it for at least as long as the contract it relates to, plus a reasonable period to cover any potential dispute. For most commercial contracts in the UK, six years is a sensible benchmark. This reflects the Limitation Act 1980 standard limitation period for contract claims. Store it with the signed document, not separately.

The UK’s approach to electronic signatures is permissive. The law does not require a specific technology or a specific appearance. What it requires is intent. A person who types their name, clicks ‘I agree’, or draws a squiggle on a screen to indicate they are signing has created a legally valid electronic signature, provided the context makes clear what they were agreeing to.

The UK’s approach is permissive and well-established. The Law Commission confirmed in its 2019 report (Law Com No 386) that electronic signatures are valid for executing documents where a signature is required by law. Courts across England, Wales, and Scotland have consistently upheld electronically signed contracts in disputes.

UK validity by document type

Green: valid without restriction. Red: electronic signing not permitted. Amber: permitted but conditions apply.

Basic Questions

What law makes electronic signatures valid in the UK?

Three sources work together.

• The Electronic Communications Act 2000 (ECA 2000), section 7, makes electronic signatures admissible as evidence in UK legal proceedings.
• The retained eIDAS framework (SI 2016/696) adds the non-discrimination principle: a signature cannot be refused or denied legal effect solely because it is electronic.
• The Law Commission's 2019 report (Law Com No 386) confirmed the position for deeds specifically. Electronic signatures are capable of satisfying a statutory signature requirement, including for deeds, provided the other formalities are met.

Does the type of electronic signature matter?

For most everyday documents, no. A typed name, a drawn squiggle, or a platform-generated signature are all legally valid. The type of signature affects evidential strength, not whether it is valid in the first place.

The type starts to matter when a specific standard is required. Some regulated transactions, cross-border EU documents, and property dealings under HM Land Registry’s qualified signature pilot require a higher tier. For those, a simple typed name would not be appropriate, even though it is valid for most other purposes. See Types of electronic signature: which method should you use?.

Are electronically signed contracts enforceable in UK courts?

Yes. UK courts have consistently treated electronically signed contracts as binding where the signature demonstrates intent and the parties understood what they were agreeing to. The Electronic Communications Act 2000 makes electronic signatures admissible as evidence, and courts consider the totality of the evidence, such as the signature, the audit trail, and the surrounding communications, when determining enforceability.

A well-documented electronic signature from a reputable platform (with a full audit trail recording who signed, when, on which device, and from which location) is in practice easier to defend in a UK court dispute than a wet-ink signature on a scanned piece of paper.

Can someone refuse to accept my electronic signature?

Not on legal grounds alone. The law does not permit a signature to be refused solely because it is electronic. If someone refuses an electronic signature, they must have a reason beyond its being digital. For example, the document is one of the statutory exceptions, or a contract between the parties specifies a different method.

Banks, some landlords, and certain public bodies still request wet-ink signatures as a matter of policy or internal procedure. That is a practical constraint, not a legal one. In many cases, asking directly whether an electronic signature would be accepted resolves the issue.

What is the position for deeds in England and Wales?

A deed, including a property transfer, mortgage, or lasting power of attorney, can be signed electronically, but with conditions. The Law of Property (Miscellaneous Provisions) Act 1989, s. 1(3) requires a deed to be signed in the physical presence of a witness who also signs to attest. This applies whether the signature is electronic or handwritten.

HM Land Registry accepts two specific methods for electronically processed deeds under Practice Guide 82 (updated 7 July 2025): a Mercury signature, where the signatory signs a printed page in wet ink in front of a witness and then scans it; and a Conveyancer-Certified Electronic Signature (CCES), where the signatory signs through a platform in the physical presence of a witness. In both cases the conveyancer certifies the process. Remote or video witnessing is not accepted.

A simple electronic signature, such as a typed name, is not sufficient to execute a deed for registration purposes, even though it is legally valid for most contracts.

What is the position for consumer contracts in the UK?

Consumer contracts, where a business sells goods, services, or digital content to an individual, can be signed electronically without restriction under the same principles that apply to all contracts. The Electronic Communications Act 2000 and the retained eIDAS framework apply equally to consumer transactions. A signature cannot be refused solely because it is electronic.

For consumer contracts signed online, such as subscription agreements, terms of service and purchase contracts, clicking ‘I agree’ or ‘I accept’ constitutes a valid electronic signature, provided the terms were clearly presented before the click and the consumer had a genuine opportunity to read them. The signature is the click; the legal question is whether the terms were adequately disclosed.

How does UK law compare to the EU position after Brexit?

The UK kept the original eIDAS Regulation rules when it left the EU, writing them into UK law through the Electronic Identification and Trust Services for Electronic Transactions Regulations 2016 (SI 2016/696). The three-tier system of simple, advanced, and qualified electronic signatures, applies in the UK in exactly the same way as before Brexit.

What changed is the mutual recognition network. Before Brexit, a qualified electronic signature from a UK trust service provider was automatically recognised across all EU member states. That automatic recognition no longer applies. UK and EU trusted lists are separate, and certificates from one are not automatically valid on the other. For most UK businesses signing documents with UK counterparties, this makes no practical difference. For those operating across both jurisdictions, it may require using certificate providers listed on both trusted lists.

For the full picture, see Do UK electronic signatures work in the EU?.

What happens if an electronic signature is disputed in the UK?

If a signature is disputed, the starting point is that it is presumed valid. The person challenging it must produce evidence that it was not genuinely made by the person named, or that the document was altered after signing.

A simple electronic signature, such as a typed name, is challenged by arguing that the named person did not type it. The response relies on surrounding evidence: the email thread, timestamps, and context. A platform-generated signature adds a structured audit trail that is significantly harder to unpick. A qualified digital signature is the most robust: any change to the document after signing invalidates it automatically and the certificate ties the signature to a verified identity.

In practice, the quality of the audit trail is the most important factor in a UK dispute. A well-documented electronic signature from a reputable platform has consistently been upheld in UK courts.

Electronic signatures and digital signatures are not the same thing, even though the terms are often used interchangeably. Understanding the difference helps you choose the right method for what you are signing.

An electronic signature is the broad term. It covers anything electronic you do to indicate you are signing — typing your name, clicking ‘I agree’, or drawing a squiggle on a screen. These are all electronic signatures, and they are all legally valid for most documents.

A digital signature is a specific, more secure type of electronic signature. It uses technology to do two things an ordinary electronic signature cannot: prove exactly who signed, and detect whether the document has been altered since. If someone changes even a single word after you sign, the signature automatically shows as invalid.

For most everyday documents, an electronic signature is all you need. For high-value contracts, property transactions, or anything where a dispute is likely, a digital signature gives you much stronger protection.

A side by side comparison

Basic Questions

Are they both legal?

Yes. Both are legally recognised in the UK, the US, and across the EU. Neither can be rejected simply because it is electronic rather than handwritten. The law treats them as valid ways to sign for the vast majority of documents.

The difference is not whether they are legal, it is how easy they are to challenge. A typed name can be disputed because anyone could have typed it. A digital signature is much harder to dispute because it is automatically tied to a verified identity and shows if the document has been changed.

Which one should I use?

For most everyday documents, such as employment contracts, supplier agreements, approvals, and non-disclosure agreements, a standard electronic signature is fine. You do not need anything more.

Choose a digital signature when:

• The contract is high value and a dispute would be costly
• You need to prove exactly who signed, not just that a name appears on a document
• The document involves property, a regulated transaction, or a government body
• The other party or your organisation requires a higher level of assurance

If you are unsure, a digital signature is never the wrong choice. It provides everything an electronic signature does, plus more.

Can I use them on the same document?

In most cases, yes. Different parties can sign the same document in different ways, and each signature is valid for that person regardless of how others signed.

The main exception is property deeds submitted to HM Land Registry. For those, the signatory and their witness must both use the same method through the same platform. Mixing methods on a deed is not accepted.

Is one more expensive than the other?

A basic electronic signature costs nothing. Typing your name or clicking a button requires no software or subscription. A digital signature requires a platform or service, which typically charges a subscription or a per-document fee.

In the EU, a change coming into effect by end of 2026 will make qualified digital signatures available free of charge to individual citizens for personal use through a new EU Digital Identity Wallet. This does not apply to the UK.

Going Deeper

What makes a digital signature more secure?

When you apply a digital signature, the software takes a snapshot of the document at that exact moment. It's a unique fingerprint. That fingerprint is locked to your verified identity. Anyone who opens the document later can check that the fingerprint still matches. If the document has been changed in any way, the fingerprint no longer matches and the signature shows as invalid.

An ordinary electronic signature does not do this. A typed name or a drawn squiggle confirms that someone intended to sign, but it does not prove who they were, and it does not detect changes. The document could be altered after signing with no visible sign that anything happened.

What is a qualified electronic signature and where does it fit?

A qualified electronic signature is the highest legal tier of digital signature. It is backed by a certificate from a government-approved authority, and in law it carries exactly the same weight as a handwritten signature. It cannot be rejected simply because it is electronic.

Getting a qualified certificate requires verified identity checks, the kind you go through when opening a bank account. This is what makes it the most trustworthy option. Most people do not need a qualified signature for everyday documents. It is typically used for high-value or regulated transactions, or where the law specifically requires it.

Below that sits an advanced electronic signature. It is still a digital signature, still tied to your identity and tamper-evident, but backed by a less stringent certificate. Most reputable e-signature platforms issue advanced signatures. These are sufficient for the vast majority of business contracts.

What about property documents?

Property deeds are treated differently from most documents. In England and Wales, a deed must be signed in the physical presence of a witness. This applies whether you sign electronically or in ink.

HM Land Registry accepts two methods for electronically processed deeds (set out in Practice Guide 82, updated 7 July 2025). A Mercury signature is where you sign a printed page in wet ink in front of a witness, then scan it. A Conveyancer-Certified Electronic Signature (CCES) is where you sign through a platform, again in the physical presence of a witness. Your conveyancer manages either process.

HMLR is also piloting a scheme accepting qualified digital signatures for certain transactions. In all cases, the applications must be submitted electronically.

Does it matter which I use in Scotland?

For most commercial contracts in Scotland, no. Both work fine. The difference becomes significant for formal documents.

In Scotland, a document that carries a qualified digital signature is ‘self-proving’. A court presumes it is valid without needing further evidence. A document with a standard advanced digital signature does not have this status, though it still satisfies the formal signing requirement. A simple electronic signature such as a typed name does not satisfy formal requirements at all for documents that must be executed under Scottish law.

How do I check whether a digital signature is genuine?

You usually do not need to do anything. Most PDF readers, including Adobe Acrobat Reader, which is free, check digital signatures automatically when you open the document. They display whether the signature is valid, when it was applied, and whether the document has been changed since signing.

A simple electronic signature gives you none of this. If someone disputes a typed name, you are relying on emails, timestamps, and context rather than an automatic verification built into the document itself. That is the practical difference in the event of a dispute.

What is the position in the US?

Both types are legally valid across the US under federal law (the ESIGN Act 2000) and under state-level laws adopted by 49 states. Neither can be rejected solely because it is electronic.

The US does not use the EU’s three-tier system of simple, advanced, and qualified signatures. Instead, US law focuses on intent and the reliability of the signing method. In practice, a digital signature from a reputable platform provides the strongest evidentiary position. For documents with specific state-law requirements, it is worth checking the rules for that state.

When you apply a digital signature, the signing software creates a unique fingerprint of the document at that exact moment. That fingerprint is locked to your identity using a private code that only you hold. Anyone who later opens the document can check that the fingerprint still matches and if the document has been changed even slightly since you signed, the check fails and the signature shows as invalid.

This makes a digital signature fundamentally different from other types of electronic signature. A typed name or a drawn squiggle confirms intent, but it does not prove identity and it does not detect tampering. A digital signature does both, automatically.

Digital signatures are legally recognised in the UK, the EU, and the US. At the highest level, they carry exactly the same legal weight as a handwritten signature. They are most commonly used for high-value contracts, property transactions, regulated documents, and any situation where it matters beyond doubt that the right person signed and the document has not been touched since.

Basic Questions

Is a digital signature the same as an electronic signature?

No, though the two terms are often confused. An electronic signature is the broad term. It covers any electronic method of signing a document, from a typed name to a tick-box to a drawn squiggle. A digital signature is one specific, more secure type of electronic signature.

Think of it this way: all digital signatures are electronic signatures, but most electronic signatures are not digital signatures. The key difference is what a digital signature adds: proof of identity and automatic detection of any changes to the document after signing. For a full side-by-side comparison, see Electronic signature vs digital signature: what is the difference?.

Is a digital signature legally valid?

Yes, in the UK, EU, and US. Digital signatures are recognised in law and carry the same legal weight as a handwritten signature when they meet the relevant standard. In the UK, they are covered by the Electronic Communications Act 2000. In the EU, the eIDAS Regulation gives a qualified digital signature identical legal standing to a handwritten signature. In the US, the ESIGN Act 2000 applies.

As with all electronic signatures, a small number of document types are excluded. Wills in England and Wales, for example, still require a wet-ink signature. For everything else, a digital signature is fully valid.

How is it different from just typing my name?

A typed name is an electronic signature, and is legally valid for most documents, but it provides minimal protection if someone challenges it. Anyone can type your name. There is no automatic record proving that you, specifically, signed at a particular time, or that the document has not been altered since.

A digital signature solves both problems. It is tied to a verified identity, not just a name. And it creates an automatic record that makes any change to the document visible after the fact. If the document is altered even slightly after you sign it, the signature shows as invalid the next time anyone opens it. A typed name cannot do either of these things.

Do I need to understand how it works to use one?

No. The technology behind a digital signature (the cryptography, the keys, the certificates) is handled entirely by the platform or software you use. As a signer, the experience is usually straightforward: you receive a link, open the document, and sign. The platform does everything else.

Where it helps to understand the basics is when you are choosing whether you need a digital signature at all, or which type. The rest of this page covers those questions in plain English.

Do I need special software?

To create a digital signature, yes. You need a platform or service that can manage the certificate and apply the signing process. In most cases this is an e-signature platform, which is a web-based service. The person signing usually does not need to install anything or create an account. They follow a link, sign, and the platform handles the rest.

To check whether a digital signature is valid, most people already have what they need. Adobe Acrobat Reader, which is free, verifies digital signatures automatically when you open a signed PDF. It shows whether the signature is valid, when it was applied, and whether the document has been changed since signing.

Going Deeper

What is a digital certificate and why does it matter?

A digital certificate is what connects your digital signature to your verified identity. It is issued by a Certificate Authority. This is an organisation that has checked who you are before issuing the certificate, in the same way a bank checks your identity before issuing a card.

Without a certificate, a digital signature is just a mathematical mark with no verified owner. With a certificate, anyone who receives your signed document can confirm that the signature belongs to you specifically, not just to someone who typed your name.

In the UK, certificate authorities must be listed on a government-maintained trusted list overseen by the Information Commissioner’s Office (ICO), which is being renamed the Information Commission in 2026. In the EU, each member state maintains its own trusted list. Only certificates from listed authorities qualify for the highest legal tier of digital signature.

Are there different levels of digital signature?

Yes. The law recognises three tiers, and the level you need depends on what you are signing.

A simple electronic signature is any electronic indication of intent to sign, such as a typed name and a tick-box. It is not a digital signature.

An advanced electronic signature is the standard offered by most reputable signing platforms. It is linked to your identity, and any change to the document after signing is automatically detectable. This is a digital signature.

A qualified electronic signature is the highest tier. It is backed by a certificate from a government-approved authority and, in law, carries the same weight as a handwritten signature. It cannot be rejected solely because it is electronic. Getting a qualified certificate requires verified identity checks, typically a government-issued ID check.

For everyday commercial contracts, an advanced digital signature is sufficient. A qualified signature is used for high-value or regulated transactions, or where the law specifically requires it.

Can a digital signature be faked or forged?

In practice, no - provided the signing system is properly set up. The security of a digital signature depends on your private key remaining secret. If it does, no one else can reproduce your signature. The mathematical systems used are designed so that even with substantial computing power, deriving a private key from the public information is not feasible.

The real risk is not mathematical - it is practical. A private key that is stolen, shared, or stored carelessly can be misused. This is why the highest-tier digital signatures are created using certified hardware that generates and stores the private key in a way that prevents it being extracted at all.

If a document is altered after signing, the signature automatically shows as invalid. You do not need to spot the change yourself - the software does it.

Where are digital signatures commonly used?

Digital signatures are used wherever the identity of the signer and the integrity of the document need to be provable. Common uses include:

• High-value commercial contracts where a dispute would be costly
• Property transactions. HM Land Registry accepts digitally signed deeds through specific processes set out in Practice Guide 82 (updated 7 July 2025)
• Financial services agreements and regulated documents
• Cross-border transactions within the EU, where a qualified digital signature has a specific legal guarantee
• Government filings and tax returns. HMRC accepts digital signatures on a range of forms

They are also used in software and technology to sign code, proving that software has not been altered since it was released, though that is outside the scope of this guide.

What is the position for property transactions?

HM Land Registry accepts two methods for electronically processed property deeds, both set out in Practice Guide 82 (updated 7 July 2025).

A Mercury signature involves signing a printed page in wet ink in front of a witness, then scanning it. This counts as an electronic signature under the eIDAS definition but uses a traditional physical signature at its core.

A Conveyancer-Certified Electronic Signature (CCES) is a fully platform-based process where you sign electronically, still in the physical presence of a witness. The conveyancer certifies that the correct steps were followed.

HM Land Registry is also running a pilot scheme accepting qualified digital signatures for a limited range of transactions. In both cases, the physical presence of a witness remains required for deeds. Remote or video witnessing is not accepted. Applications must be submitted to HMLR electronically.

Does it work differently in Scotland?

The technology is the same but the legal consequences differ for formal documents. In Scotland, a document that carries a qualified digital signature is ‘self-proving’ meaning a court presumes it is valid without needing additional evidence. A document with an advanced digital signature does not have that status, though it does satisfy the authentication requirement for formal documents.

For everyday commercial contracts that do not require formal writing, any level of digital signature works in Scotland, as elsewhere in the UK.

The Scottish rules are set out in the Electronic Documents (Scotland) Regulations 2014.

What is the position in the EU after eIDAS 2.0?

The EU updated its electronic signature rules in 2024 with a new regulation known as eIDAS 2.0. The core rules about digital signatures remain the same. What eIDAS 2.0 adds is a mandatory EU Digital Identity Wallet, which every EU member state must make available to citizens by the end of 2026. This wallet will allow citizens to use a qualified digital signature free of charge for personal use.

This does not apply to the UK. The UK has its own framework, based on the original eIDAS rules as they were written into UK law after Brexit. UK-issued digital signature certificates are not automatically recognised within the EU’s mutual recognition system, which is a practical consideration for organisations operating across both jurisdictions.
