How Singapore's ETA 2010 governs simple and secure electronic signatures, and how to comply with MAS guidelines.
Singapore's Electronic Transactions Act 2010 distinguishes between a 'simple electronic signature' (any reliable method indicating signer intent) and a 'secure electronic signature' (asymmetric cryptography from a Netrust or other accredited Certification Authority).
Most commercial contracts work with a simple e-signature. Secure electronic signatures benefit from a statutory presumption of integrity — courts presume the document hasn't been altered, shifting the burden to the challenger.
The First Schedule excludes wills, negotiable instruments, real-property leases over 7 years, and certain testamentary documents.
