eSignature legality summary
Where a law requires a signature (or attaches consequences to its absence), that requirement is met if a method identifies the person and indicates their intent and is as reliable as appropriate (or is proven to have done so). The ETA distinguishes a plain electronic signature, a “secure electronic signature” (which carries presumptions of attribution, intent, authenticity, and integrity), and a “digital signature” (asymmetric-cryptography based).
Types of permitted electronic signature
IMDA guidance treats an electronic signature as a record of a person’s intention or consent — for example a pasted signature image, stylus or finger signing, ticking “I accept,” or selecting an option in e-signature software. A “secure electronic signature” additionally must be unique to the person, capable of identifying them, under their sole control, and linked to the record so any later change invalidates it (via a specified or commercially reasonable security procedure).
Documents that may be signed electronically
Typically no special requirements for commercial agreements (procurement, software licensing, loans), NDAs, corporate resolutions (unless the constitution provides otherwise), board and shareholder minutes, Singapore government filings, and negotiable/transferable instruments such as bills of exchange, promissory notes, and bills of lading.
Use with caution / not typically appropriate
Take care with deeds. A plain electronic signature that is not a “secure electronic signature” lacks the statutory presumptions, so if challenged the relying party may need further evidence — authentication, tamper-evidence, and an audit log of the signing session.
