Is an electronic signature legal in Brunei?
A written signature is not required for a valid contract — parties can agree verbally, electronically, or on paper. The ETA confirms a contract is not unenforceable merely for being electronic, and electronic records are admissible under the Evidence Act (ss. 35A, 62). Brunei applies a tiered approach with a “Secure Electronic Signature.”
What types of electronic signature are recognized in Brunei?
An ordinary electronic signature is valid; a “Secure Electronic Signature” (via a prescribed or agreed security procedure) is unique to and identifies the person, is under their sole control, and is linked so that any change invalidates it — and is presumed authentic, shifting the burden to a challenger. A “Secure Digital Signature” uses a valid certificate from a government-certified provider.
