eSignature law in Singapore
Electronic signatures are legally binding in Singapore under the Electronic Transactions Act 2010, which gives electronic records and signatures the same legal effect as paper.
Governing law: Electronic Transactions Act 2010 (ETA) (2010)
Singapore's Electronic Transactions Act 2010, modelled on the UNCITRAL Model Laws and the UN Convention on Electronic Communications, provides that a contract is not denied validity solely because it was formed electronically, and that a signature requirement is met by an electronic method that identifies the signer and indicates their intention, and is reliable for the purpose. The ETA also recognises "secure electronic signatures" and digital signatures supported by certificates from accredited certification authorities, which attract evidential presumptions of authenticity and integrity. For ordinary commercial contracts, a simple electronic signature is sufficient and widely used. The Infocomm Media Development Authority (IMDA) administers the accreditation scheme for certification authorities.
