Wet Signatures vs E‑Signatures: What Australian Businesses Need To Know

Printing a contract just to sign it in pen can feel old‑school when your team, clients and suppliers are spread across Australia. The good news is that electronic signatures are now widely accepted in Australian law - but there are still moments when a handwritten (“wet ink”) signature, or a specific form of electronic execution, is required.

In this guide, we’ll unpack the key differences between wet signatures and e‑signatures, where each is legally accepted, and the practical steps to implement a compliant digital signing process. Our aim is to help you move faster without compromising enforceability, especially for company documents, deeds, witnessed documents and property matters.

We’ll keep this in plain English and point you to practical resources so you can confidently decide when to use each method and how to put strong processes around them.

Wet Vs E‑Signatures: The Basics

A wet signature is the traditional handwritten signature using ink on paper. It’s familiar, tangible and still common for formal documents or where legislation or a registry requires it.

An electronic signature (e‑signature) is any electronic method that indicates approval or agreement. This can include typing your name, clicking “I agree,” drawing your signature with a mouse or stylus, or using a dedicated signing platform that captures an audit trail.

Both can be legally valid in Australia. Whether a signature method works for your document depends on the law that applies to that document, how the parties execute it, and whether any special formalities (like witnessing) are required. If you want a quick refresher on what makes a signature valid, see our explainer on a valid signature.

Are E‑Signatures Valid Under Australian Law?

Yes - in most cases. The Electronic Transactions Act 1999 (Cth) and each state and territory’s equivalent legislation recognise electronic signatures where three things are met:

• Consent: Everyone agrees to use electronic communication and signatures.
• Identity and intention: The method identifies the person and shows they intended to sign.
• Reliability: The method is as reliable as appropriate for the purpose (for example, a platform that records timestamps, IP address and an audit trail).

On top of that framework, there are important, business‑specific rules to note:

Company documents and deeds

For companies, the Corporations Act now expressly allows electronic execution. Under section 127, a company can execute documents (including deeds) electronically, and split execution and counterparts are permitted. No witness is required when a company executes under section 127.

Companies can also authorise agents to sign on their behalf under section 126, including via electronic means. These reforms make it much easier to execute documents efficiently and prove due execution.

Individuals and partnerships

For individuals or partnerships, e‑signature validity depends on the underlying document type and your state or territory rules. Many jurisdictions now allow electronic deeds and remote witnessing for certain documents, but the details differ, so always check the local position before going fully digital.

Documents that involve registries or regulators

Where a government agency or registry is involved (for example, ASIC filings or land titles), the relevant practice rules and lodgement portal often set the format. ASIC accepts electronic lodgement and usually electronic signatures for forms submitted online. Land registries typically support e‑conveyancing through prescribed platforms and subscriber rules.

If you want a broader refresher on execution formalities across different document types, our guide to signing documents covers the key concepts in one place.

When Is A Wet Signature Still Required?

Thanks to permanent reforms, wet ink is now the exception rather than the rule - but there are still scenarios where you should stick to paper or confirm the exact electronic method allowed.

Common scenarios to treat as “wet ink required” (or confirm strict e‑execution rules)

• Wills and codicils: Most states still require paper and in‑person witnessing for wills. Some courts can “save” non‑compliant wills, but that’s a litigation risk you should avoid. Wet ink with in‑person witnesses remains best practice.
• Enduring powers of attorney and some personal appointments: Execution and witnessing rules are strict and vary by state. Many still require physical witnessing by prescribed witnesses.
• Documents that a specific registry prescribes in paper: A small number of forms in specialised areas may still need paper or a particular certification method. Always check the registry’s current practice directions.

What’s changed - and now commonly permitted electronically

• Deeds: Several jurisdictions have removed the “paper, parchment or vellum” requirement and permit electronic deeds for individuals. Companies can execute deeds electronically under section 127. Because rules differ across states, confirm the requirements where the deed is made and performed. If you’re unsure whether your document should be a deed or an agreement, start with our overview of what a deed is.
• Statutory declarations and affidavits: Permanent reforms now allow electronic or remote witnessing for many Commonwealth and state declarations (with strict identification and platform rules). Requirements vary - check the current rules in your jurisdiction before relying on remote witnessing.
• Property transactions: E‑conveyancing is now standard across Australia. Land registries allow electronic instruments through approved platforms, with specific identity verification and client authorisation requirements. Agents and subscribers must follow the participation rules, but the “signature” itself will often be electronic in form.
• ASIC and other regulator filings: Most regulator portals accept e‑signed forms and supporting documents when lodged electronically.

Bottom line: the landscape has shifted in favour of digital execution. But where the document is high‑value, involves personal appointments, or engages a registry with strict rules, double‑check the current position and consider taking advice.

Witnessing And Remote Signing: What’s Allowed?

Some documents still require a signature to be witnessed. The big questions are who can witness and whether they must be physically present or can use audio‑visual technology.

In‑person witnessing

For traditional in‑person witnessing, the witness must see the person sign. Depending on the document, the witness may also need to include their name, address, occupation or qualification. If you need a quick refresher on categories of witnesses, see who can witness a signature and, for NSW, our overview of the NSW Oaths Act 1900 authorised witnesses.

Remote witnessing (audio‑visual link)

During and after the pandemic, most jurisdictions introduced permanent rules that allow certain documents to be witnessed via audio‑visual link, with specific steps to verify identity, observe signing, and endorse the document. The permitted documents and steps vary by state and by document type.

As an example, NSW has permanent rules for remote witnessing of specified documents. If you operate in NSW, our guide to remote witnessing walks through the process at a high level. Other states have similar frameworks, but the details differ.

Practical tips for witnessed documents

• Confirm the exact witness category required before you sign.
• If using remote witnessing, follow the steps in the relevant regulations to the letter (including endorsements and technology requirements).
• Avoid mixing methods. If part of a package must be wet‑ink witnessed, keep the whole set consistent unless your lawyer confirms a split process is acceptable.

Company Execution: Getting Section 127 Right

For many businesses, the simplest way to ensure a contract is enforceable against the company is to execute it properly under the Corporations Act.

Why section 127 matters

When a company signs under section 127, the counterparty benefits from a statutory assumption that the document has been duly executed. That makes enforcement easier because you don’t need to prove the authority behind the signatures.

How companies can sign

• Two directors sign; or
• A director and a company secretary sign; or
• For a proprietary company with a sole director who is also the company secretary, that person signs alone.

You can sign electronically, use split execution and counterparts, and execute deeds electronically. If a company uses an agent, section 126 allows an authorised person to execute on its behalf (also electronically).

If parties are signing on separate copies, it’s fine to manage “counterparts” as long as the document permits it. Our quick guide to being signed in counterpart covers what to include and how to keep your records straight.

Finally, make sure your document type matches the execution you’re using. If you intend to sign as a deed, check it actually needs to be a deed (not a simple agreement), that the deed includes the required formality wording, and that each signatory has used an accepted method for a deed in their jurisdiction.

How To Roll Out A Strong E‑Signature Process

Moving to e‑signatures is as much about process as it is about technology. A few practical steps will help you avoid disputes and keep regulators, banks and counterparties comfortable with your execution practices.

1) Choose appropriate methods by document type

Map your common documents and decide on the default execution method for each. For example:

• Sales contracts, NDAs, services agreements: e‑signature via a trusted platform.
• Company deeds, loan deeds: section 127 electronic execution with platform audit trail and counterpart clause.
• Wills and enduring powers of attorney: wet ink in person with prescribed witnesses.
• Affidavits/stat decs: follow the current rules for your jurisdiction and document type.

2) Use reputable signing tools

Look for a provider with strong security, identity options, audit trails and data retention controls. The platform should allow you to download a signed PDF and a certificate of completion. This supports the reliability requirement under the Electronic Transactions legislation and makes disputes less likely.

3) Bake execution into your templates

Include clear signing blocks for companies (with section 127 options), individuals and agents, plus a counterparts clause. If a document may be a deed, ensure the opening and execution blocks are drafted as a deed. Small details like these reduce execution errors and back‑and‑forth.

4) Verify identity and authority for high‑risk deals

For higher‑value or sensitive transactions, add identification steps (such as two‑factor authentication in the signing platform). Where someone signs on behalf of a company under section 126, confirm their authority.

5) Keep thorough records

Store the final signed document (and certificate) in a central system with version control. If you end up in a dispute, a strong record helps prove who signed and when. If you’re curious about the broader principles, our guide to signing documents and the earlier overview of a valid signature are good companions to your internal policy.

6) Update your policies and contracts

Tell your staff and counterparties what methods you accept, and reflect this in your standard terms and execution blocks. While you’re updating templates, it’s a good time to ensure other essentials are covered too - for example, having a compliant Privacy Policy for any personal information you collect from signatories, using the right Employment Contract for new hires, or setting the ground rules between founders in a Shareholders Agreement if you’re growing the team.

7) Know when to pause and get advice

If a document involves unusual witnessing rules, a cross‑border party, a land registry, or a large financial exposure, it’s worth getting a quick sense‑check before you sign. That’s especially true for deeds and witnessed documents, where a small misstep can create enforceability issues later.

Common pitfalls to avoid

• Mixing execution methods without planning (for example, some parties e‑sign while a witness signs a paper version) and ending up with a mismatch in the final “package.”
• Assuming any tick‑box is fine for everything. Reliability must match the risk - use stronger methods for higher‑value documents.
• Forgetting about authority. A beautifully e‑signed document is still vulnerable if the person who signed lacked authority to bind their company.
• Skipping a counterparts clause when you know signatories will sign on separate copies.

Key Takeaways

• E‑signatures are generally valid in Australia if you meet consent, identity and reliability requirements under the Electronic Transactions laws.
• For companies, section 127 allows electronic execution of documents and deeds, with no witness needed, and split execution and counterparts allowed.
• Many jurisdictions now permit electronic deeds and remote witnessing for certain documents, but the rules vary. Wills and some personal appointments still typically require wet ink witnessed in person.
• Registry‑driven processes (land registries, ASIC) usually allow electronic execution within their systems - follow the current practice rules and identity requirements.
• Build a policy around when to use wet ink vs e‑signatures, use reputable tools, include clear execution blocks, and keep strong records to reduce disputes.
• If a document is high‑value or involves special formalities, confirm the current requirements and consider getting advice before signing.
