eSignature legality summary
An electronic signature that can identify the signatory and establish that they signed is valid; enforceability is not denied merely because the signature is electronic. Where statutes or the parties’ agreement permit an electronic signature in place of a signature or seal, it is enforceable. Certified (digital) signatures can be assessed against the official Guidelines on Electronic Signature Certification Services.
Types of permitted electronic signature
Any electronic signature that identifies the signatory and shows that they signed is acceptable under the Digital Signature Act. Enhanced certified (digital) signatures can be certified for compliance with the published Guidelines.
Documents that may be signed electronically
Almost any contract may be electronically signed (a general exception is surety contracts). Corporate-resolution minutes may generally be e-signed, although where a resolution contains a “registrable matter” for the corporate registration court, seals are used in practice.
Use with caution / not typically appropriate
Surety contracts generally require more formality. Registrable corporate matters submitted to the registration court are, in practice, affixed with personal or corporate seals rather than e-signatures. Government filings may be accepted at the relevant authority’s discretion.
- Surety contracts (generally)
