Definition
Signatory
The person or organization who actually signs a document.
In Depth
If your name goes on the line, you are the signatory. The word applies equally to an individual signing a lease and to a government signing a treaty. In an electronic signing, the signatory is whoever the system asks to apply a signature.
Consistent across the US, UK and EU. It is a plain-English term, not a region-specific legal definition. One footnote: EU and UK eIDAS use the closely related word "signatory" in their own text to mean the natural person who creates the signature.
