Electronic signatures vs wet ink signatures in Australia

A supplier wants to close the deal today. Your new employee starts on Monday. The bank needs the loan documents back before the end of the week. Each of those moments forces the same question: can you sign electronically, or do you need to print, sign in ink and scan?

For most commercial documents in Australia, the answer is that a well-executed electronic signature is just as valid as a handwritten one — and far faster. But some document types and some counterparties still require wet ink, and the rules for deeds, statutory declarations and documents headed to a land registry are more detailed than most business owners realise. Getting it wrong at the wrong moment can delay a settlement, invalidate a guarantee or leave a company exposed.

The two options — and the false choice hidden inside them

A wet ink (or "wet") signature is your handwritten name in ink on a physical page. An electronic signature is any digital method that identifies you and shows your intention to be bound — a typed name in a docusign field, a drawn signature on a touchscreen, or a click-to-accept button all qualify if the conditions under Australian law are met.

The hidden complexity is not really about which method you prefer. It is about whether the document type or counterparty restricts your choice. For everyday commercial contracts between businesses, both methods generally work. The decision becomes more constrained when you are dealing with deeds, property documents, statutory instruments, or parties who have their own requirements — banks, government agencies and overseas entities in particular.

Matching the method to the document

What type of document you are signing

The starting point is the Electronic Transactions Act 1999 (Cth) and its state and territory equivalents. Under s 10 of that Act, an electronic signature satisfies a legal signature requirement if the method:

• identifies the signatory and indicates their intention in respect of the document;
• is as reliable as appropriate for the purpose for which the document was generated; and
• the person to whom the signature is given has consented to receiving it in electronic form.

Most commercial contracts, NDAs, employment agreements and service agreements sit comfortably within those conditions. A reputable e-signature platform — one that captures a time-stamped audit trail and records the IP address and identity steps — gives you the best evidence that all three conditions were met.

Deeds are the main exception for companies. A deed executed by a company under s 127 of the Corporations Act 2001 (Cth) can be signed electronically and does not need to be witnessed when the company executes under that section. The Corporations Amendment (Meetings and Documents) Act 2022 (Cth) made these rules permanent from 23 February 2022. However, an individual signing a deed in their personal capacity generally still needs a wet ink signature witnessed by an eligible adult — the rules vary by state, and most jurisdictions have not extended electronic execution to individual deed signatories.

Wills, powers of attorney and enduring guardianship appointments are subject to strict state and territory rules. Most jurisdictions still require wet ink, and witnessing requirements vary sharply. Do not rely on electronic execution for these documents without specific advice for the state or territory where the document is created.

Land registry and mortgage documents are governed by the relevant state land titles office, and acceptance varies by jurisdiction and lender. Confirm requirements before you execute, not after.

Documents going overseas may require notarisation or an apostille, both of which typically involve a wet ink step and in-person attendance before an authorised officer.

Whether a company or an individual is signing

This distinction matters more than most people appreciate.

For companies, s 127 is the preferred execution route. It creates a statutory presumption that the document has been properly executed, which protects the counterparty and reduces friction if the document is later reviewed by a lender, regulator or court. Where an officer or agent signs instead of the company itself, the source of that authority should be clearly documented — typically a board delegation or resolution consistent with s 126 of the Corporations Act 2001 (Cth).

Whether split or counterpart execution is involved

It is now common for signatories to sign at different times or places. Under the 2022 amendments, companies executing under s 127 can use split execution — two directors, or a director and company secretary, can sign separate counterparts of a document, in any combination of physical and electronic form. The key requirement is that each signatory's copy must contain the entire contents of the document (not just the execution page).

For contracts generally, including a counterparts clause in the document avoids any doubt about whether separately-signed copies form one binding agreement. Even without such a clause, separate copies can sometimes bind the parties, but the clause makes administration cleaner and removes a potential argument.

What evidence you can produce

With a wet ink signature on paper, evidence of execution comes from the document itself, any witness statement, and your filing practices. With an electronic signature, evidence lives in the platform's certificate of completion — which records the signer's email address, IP address, time stamp and any identity verification steps taken.

If a dispute ever arises, the question is not just "was there a signature?" but "can you prove who signed and that they intended to be bound?" A well-configured e-signature platform often produces a cleaner audit trail than a paper process. Conversely, a typed name in the body of an email with no platform is harder to rely on, even though it may technically meet the legal minimum.

Counterparty and third-party requirements

Even when the law permits electronic execution, a counterparty's own policies may not. Banks routinely require wet ink on personal guarantees, mortgage documents and facility agreements. Government agencies have varying internal policies. Overseas parties may insist on notarisation. Ask early in any high-value transaction whether the other side or any third party (such as a land registry or lender) requires a specific form of execution — building a requirement into the timeline after documents have been drafted adds avoidable delay.

When each signing method works

Most businesses find that the following split works in practice:

Electronic signatures are generally fine for:

• Commercial contracts, NDAs and service agreements between businesses or with individuals
• Employment contracts and contractor agreements
• Company board minutes and resolutions (subject to your constitution)
• Loans and security documents between companies — check lender requirements first
• Company deeds executed under s 127 of the Corporations Act 2001 (Cth)

Wet ink (and often witnessing) is still required or strongly advisable for:

• Wills and most powers of attorney or enduring guardianship appointments
• Deeds signed by individuals in their personal capacity
• Statutory declarations and affidavits (check jurisdiction-specific rules for any remote or electronic witnessing options)
• Documents requiring notarisation or an apostille for overseas use
• Land registry dealings and mortgages in some jurisdictions
• Any document where the counterparty or their risk policy insists on it

The pattern is clear: once a document involves individual personal capacity execution, succession, property registration, or an overseas formality, the default shifts toward wet ink unless you have confirmed otherwise.

How Artificer Legal can help you get this right

Choosing the wrong execution method can mean a document is unenforceable when you need it most — a guarantee that cannot be called in, a deed that does not bind, or a property transaction that stalls at settlement. Artificer Legal can help you:

• Map your document types to the correct execution method under Commonwealth and applicable state law, so your team has a clear internal playbook rather than having to make a judgment call each time.
• Review high-value or unusual documents before they go out — particularly deeds, guarantees, cross-border agreements and anything that will be reviewed by a bank or regulator.
• Identify authority gaps — including whether the person signing on behalf of a company has documented authority under s 126 or whether execution should instead be under s 127.
• Draft execution blocks and counterparts clauses that reflect how your signatories will actually sign, reducing the risk of a defective closing set.

For transactions where multiple parties are signing in different locations over several days, we can also help you design a signing process that meets the law without adding unnecessary friction.

When wet ink is still required

The default for Australian businesses should be electronic signatures — they are faster, generate better evidence, and are valid for the vast majority of commercial documents. The switch to wet ink is triggered by document type (deeds signed by individuals, wills and powers of attorney, land registry dealings), by individual versus company capacity, and by counterparty policy. The costly mistake is not knowing those triggers in advance and discovering them at the point of execution.

In short: electronic by default; wet ink when the document type, the signatory's capacity, or the counterparty's requirements demand it. If you are unsure which applies to a particular document or transaction, confirm before you send — not after.

Key points covered in this article:

• An electronic signature is valid under the Electronic Transactions Act 1999 (Cth) (and state equivalents) if it identifies the signatory, indicates their intention, is appropriately reliable, and the recipient has consented.
• Companies can execute documents — including deeds — electronically and in counterpart under s 127 of the Corporations Act 2001 (Cth), following permanent reforms in February 2022.
• Individuals signing deeds in their personal capacity generally still need a wet ink signature and a witness; most jurisdictions have not extended electronic execution to that scenario.
• Wills, powers of attorney, statutory declarations, land registry dealings and documents requiring notarisation typically still need wet ink, with rules varying by state and territory.
• A counterparts clause removes doubt when signatures are being collected separately, regardless of whether the method is electronic or wet ink.
• Where the stakes are high, confirm the execution method early in the transaction — the cost of a last-minute adjustment is much lower than the cost of a defective document.
