Digital signatures are recognised with legal equivalence to “wet signatures” so that people can transact digitally.
Estonia: eSignatures for registering a company online, e-banks, online voting system and electronic tax filing.
United States: 2001 ESIGN Act states a contract or signature “may not be denied legal effect, validity, or enforceability solely because it is in electronic form”.
European Union: Article 5 of the Electronic Signatures Directive mandates that European states must regard electronic signatures with the same authority as wet signatures.
Elsewhere: Many other G20 countries implement legislation that gives legal recognition to digital signatures for most purposes. Some countries enforce restrictions: Argentina prohibits use for certain legal documents and public deeds; Canada prohibits use for wills and marriage controls; China, in practice, prohibits use in corporate documents that require public notarisation.
