E-signing under the Electronic Transactions Act in Australia
E-signing in Australia is governed by the Electronic Transactions Act 1999 (Cth) and its state equivalents. A signature is valid where the method identifies the signatory, indicates approval, is as reliable as appropriate, and the recipient consents. This guide sets out 10 obligations for enforceable electronic execution across Commonwealth and state law.
Coverage
Every Australian business or law firm that executes contracts, deeds, board resolutions or regulated forms electronically — whether using off-the-shelf e-signing tools or bespoke portals.
Legal basis
Electronic Transactions Act 1999 (Cth) ss 8–12 and state equivalents (NSW, VIC, QLD, SA, WA, TAS, ACT, NT). Corporations Act 2001 (Cth) ss 110A, 126, 127 for companies. ARNECC Model Participation Rules for electronic conveyancing.
The obligations
Confirm the document is eligible for e-signing
Some documents are excluded from the federal or a state Electronic Transactions Act, including certain wills, powers of attorney and migration documents — check the applicable regulations before signing.
Identify the signatory
Use a method that identifies the person signing and shows their approval of the document, such as a typed name, click-to-sign, drawn signature or digital certificate.
Use a method appropriate to the purpose
Select a signing method that is as reliable as appropriate for the purpose, taking account of the value, risk and formality of the document.
Obtain the recipient's consent
Confirm the recipient consents (expressly or by conduct) to receive the document electronically. For consumer transactions, consent should be explicit and recorded.
Meet Corporations Act execution requirements
For company execution, apply s 110A and s 127 so the document shows signatures of the relevant directors, secretary or sole director and is capable of being reproduced.
Handle deeds with jurisdictional care
Deeds can be executed electronically under the Corporations Act and most state property statutes, but witness rules for individuals differ by state and must be checked before signing.
Capture a full audit trail
Record the signatory's identity, IP address, timestamps, authentication method and document hash, typically through a reputable e-signing platform.
Support counterpart and split signing
Where multiple officers sign separately, ensure each counterpart is identical, all signatures are collected and the complete executed copy is retained.
Comply with state e-conveyancing rules
For land dealings, use an ELNO and Verification of Identity standards that satisfy ARNECC Model Participation Rules and state electronic conveyancing legislation.
Store signed documents for the limitation period
Retain the signed document, completion certificate and audit trail in a manner that preserves integrity and metadata for the full applicable limitation period.
What happens if you do not comply
An improperly executed electronic document may be void, unenforceable or require rectification, exposing the firm or business to professional negligence claims and transactional losses. Breach of Corporations Act execution provisions can attract ASIC enforcement action.
Reporting requirements
No routine reporting obligations, but businesses must be able to produce execution evidence — completion certificates, audit trails, consent records — if validity is challenged in a dispute or audit.
What firms should do today
- Adopt a single approved e-signing platform with enforced authentication
- Maintain a list of document types excluded from electronic signing under state or federal law
- Keep a standing execution checklist covering consent, authority and witnesses
- Store signed documents alongside completion certificates in the matter file
- Review the e-signing policy whenever the Electronic Transactions Act, Corporations Act or state property rules change
