ESIGN Act

The US federal law that made electronic signatures legally valid nationwide.

In Depth

Signed in 2000, the Electronic Signatures in Global and National Commerce Act settled the question of whether online signatures count. Its core promise is straightforward: a contract or record cannot be tossed out simply because it is electronic rather than on paper. It applies to transactions in interstate and foreign commerce and works alongside the state-level UETA.

US only. This is a United States federal statute with no application in the UK or EU. The rough equivalents are the Electronic Communications Act 2000 and UK eIDAS in the UK, and eIDAS in the EU.
