Are Electronic Signatures Legally Binding?
In many countries, yes. Electronic signatures are generally legally binding for most contracts, as long as the signer intended to sign. There are exceptions, and the evidence you keep matters.
United States: ESIGN Act and UETA
The federal ESIGN Act (2000) says a signature or contract cannot be denied legal effect just because it is electronic. Most states have also adopted the Uniform Electronic Transactions Act (UETA).
Certain documents are excluded, such as wills and some family-law and court documents, and some notices have special rules.
European Union: eIDAS
The eIDAS Regulation says an electronic signature cannot be denied legal effect just because it is electronic. It defines three levels: simple, advanced and qualified. Only a qualified electronic signature automatically has the same effect as a handwritten one in all member states.
What makes an e-signature hold up
Courts generally look at intent to sign, consent to do business electronically, a clear link between the signature and the document, and records showing who signed and when.
That is why an audit trail matters. eSignSimple's sending for signature records an audit trail (early access). This article is general information, not legal advice; check local rules for important documents.
Frequently asked questions
Can I e-sign a will?
In most places wills are excluded from general e-signature rules or have their own requirements. Check local law.
Is a typed name a valid signature?
Often, yes, if it shows intent to sign. The evidence around it, such as an audit trail, strengthens it.
Are e-signatures valid outside the US and EU?
Many countries have similar laws, but rules vary. See our country-by-country legality pages.
