What is an electronic signature?

An electronic signature (e-signature) is any electronic indication of intent to agree to a document — typically a typed name, a drawn signature, or a click — captured together with a record of who signed, when, and from where. For everyday business agreements it carries the same legal weight as a handwritten signature in most countries.

Are electronic signatures legally valid?

Yes — electronic signatures are legally valid and enforceable for the vast majority of business agreements. Laws including the U.S. ESIGN Act, the EU's eIDAS regulation, and Israel's Electronic Signature Law (2001) recognize electronic signatures, as long as the signer intended to sign and a reliable record links the signature to the document and the signer.
