Is an electronic signature legal in Singapore?
Short answer: Yes. Under section 8 of the Electronic Transactions Act 2010, a legal signature requirement is met by an electronic method that identifies the signer and shows their intention, provided it is reliable enough for the purpose, except for the matters in the Act's First Schedule.
The laws
Electronic Transactions Act 2010
Singapore's main electronic signature law, based on UNCITRAL model laws. Section 8 sets the signature rule, sections 18 and 19 create secure electronic signatures with presumptions, and section 4 with the First Schedule lists excluded matters.
Electronic Transactions (Amendment) Act 2021
Added Part 2A on electronic transferable records, adopting the UNCITRAL Model Law, and removed negotiable instruments and similar transferable documents from the First Schedule.
The signature rule
Section 8 says a rule of law requiring a signature is met for an electronic record if a method identifies the person and indicates their intention regarding the information, and the method is either as reliable as appropriate in all the circumstances, or proven in fact to have fulfilled those functions.
Secure electronic signatures
Under section 18, a signature is secure if, through a specified security procedure or a commercially reasonable one agreed by the parties, it can be verified that it was unique to the signer, capable of identifying them, under their sole control, and linked to the record so that any change would invalidate it.
Section 19 then presumes, unless proven otherwise, that a secure electronic signature is the signer's and was affixed with the intention of signing. Ordinary electronic signatures get no such presumption, so the evidence you keep matters.
What the Act excludes
The First Schedule excludes Part 2 of the Act from: the creation or execution of a will; the creation, performance or enforcement of an indenture, declaration of trust or power of attorney (except implied, constructive and resulting trusts and lasting powers of attorney under the Mental Capacity Act 2008); contracts for the sale or other disposition of immovable property; and conveyances or transfers of interests in immovable property.
Practical tips for Singapore businesses
Outside the First Schedule, section 8 covers most contracts. Keep an audit trail showing identity and intent, since that is what section 8 requires.
eSignSimple provides simple electronic signatures with an audit trail that records timestamps, IP addresses and a document hash. It does not issue qualified, advanced or certificate-based signatures, so where a law requires one of those you will need a licensed or accredited provider.
This page is general information about how electronic signature law works, not legal advice. For a specific high-value or regulated transaction, check with a qualified lawyer in the relevant jurisdiction.
Documents that need more than a simple e-signature
- Creation or execution of a will
- Indentures, declarations of trust and powers of attorney (except implied, constructive and resulting trusts and lasting powers of attorney)
- Contracts for the sale or other disposition of immovable property or any interest in it
- Conveyance of immovable property or transfer of any interest in it
