Are Electronic Signatures Legally Binding?

Before you sign a contract on screen and send it back, it's fair to wonder whether it actually counts. The short answer: for the overwhelming majority of everyday agreements, an electronic signature is just as legally binding as a handwritten one — but there are specific exceptions worth knowing.

The laws that recognize e-signatures

In the United States, the federal ESIGN Act and the state-level UETA establish that a signature can't be denied legal effect simply because it's electronic. In the European Union, the eIDAS regulation does the same across member states, defining tiers of electronic signature with increasing legal weight. Many other countries have parallel laws. The common principle: intent to sign and agreement to the terms is what matters, not ink.

What makes an e-signature hold up

• Clear intent to sign — the signer meant to commit to the agreement.
• Consent to do business electronically — both parties agreed to the method.
• Association with the record — the signature is connected to the document signed.
• A retained copy — the signed document is kept and can be reproduced.

The exceptions

Some documents are commonly carved out and may still require a traditional signature or notarization: wills and certain trusts, some property deeds, adoption and divorce papers, and a handful of court-related documents. The exact list varies by jurisdiction, so for high-stakes or unusual documents, confirm the local requirement.

For the everyday stream of agreements — offers, NDAs, vendor contracts, consent forms — signing electronically is both valid and far faster. A tool that lets you sign in your browser keeps the document private while you do it.
