E‑signatures have become the go‑to way to sign contracts in Australia. They’re fast, convenient and perfect when your team, suppliers or clients are in different locations.
But are they always legally binding? What if the contract needs a witness or must be signed as a deed? And how do you actually execute a contract correctly using an e‑signature platform?
In this guide, we’ll walk you through the rules that apply in Australia, a practical step‑by‑step for e‑signing, and the common pitfalls to avoid so your agreements hold up if they’re ever tested.
What Is An E‑Signature In Australia?
An electronic signature (e‑signature) is any method of indicating your agreement to a document in a digital form. This might be typing your name, clicking “I agree,” drawing your signature with your mouse or finger, or using an e‑signing platform that inserts a digital image of your signature and captures audit data.
In Australia, the law focuses less on what the signature looks like and more on whether the method you chose proves that the right person signed and that they intended to be bound. That’s why platform features like authentication, time‑stamped audit trails and tamper‑evident records are so valuable.
If you’re deciding between pen‑and‑paper or digital, it helps to understand the differences between wet‑ink and electronic signatures and when each one is appropriate.
Are E‑Signatures Legally Valid?
Yes, e‑signatures are generally valid across Australia under the Electronic Transactions Acts (Commonwealth and State/Territory equivalents). In broad terms, an e‑signature will be accepted if:
- There is a method to identify the person and indicate their intention to sign.
- The method is as reliable as appropriate in the circumstances (or is proven in fact to have identified the person and their intention).
- The recipient consents to receiving the signature electronically.
That said, some documents or circumstances have extra rules or are excluded from electronic signing in certain jurisdictions. The most common areas to check include deeds, documents that require witnessing, and specific statutory forms. If you’re unsure, it’s worth confirming the legal requirements for signing documents in Australia before proceeding.
Companies can also sign electronically. Where a company signs under section 127 of the Corporations Act (which gives certain evidentiary benefits), you should follow the rules for execution by two directors, a director and company secretary, or a sole director/secretary, and make sure your method meets reliability and identification standards. For more detail, see our guide to signing documents under section 127.
How To Sign A Contract Using E‑Signatures (Step‑By‑Step)
Once you’ve confirmed your document can be e‑signed, here’s a practical process you can follow.
1) Prepare A Clean, Final Version
Make sure the contract is finalised and in a non‑editable format (usually PDF). If you need to make changes, use a clean amendment or redline and ensure everyone has accepted the updates before you send it for signature. If you want a professional check before you sign, consider a quick contract review so you know the terms are balanced and enforceable.
2) Decide Who Needs To Sign (And How)
- List all parties and authorised signers (e.g. company directors, trustees, or individuals).
- Confirm any witnessing requirements or special execution blocks (for example, a company signing under section 127, or a deed that may require specific wording).
- Record full names and titles for each signer so the signature blocks are accurate.
3) Choose A Reliable E‑Signing Method
Use a trusted e‑signature platform that provides authentication options, a full audit trail, and tamper‑evident records. These features help show that the right person signed, when they signed, and that the document wasn’t altered afterwards.
Where your counterpart prefers email confirmation instead of a platform, keep evidence of their consent to e‑signing, their identity, and their clear intent to be bound (for example, a signed, time‑stamped PDF plus a confirming email from the same corporate address). A platform is usually simpler and more robust.
4) Set Up The Signing Fields Properly
- Insert signature, name, title and date fields for each signer.
- If witnesses are required, add separate witness name and signature fields.
- For companies, include the correct execution wording and role labels, consistent with section 127 or the company’s constitution.
5) Send For Signature With Clear Instructions
In your message, note the signing deadline, who will sign first, and any special steps (like a witness being present at signing). Make it clear that by signing electronically, each party consents to electronic execution.
6) Monitor, Remind And Complete
Track progress, send reminders as needed, and confirm once everyone has signed. The platform should issue a final executed copy (often a single PDF containing the agreement and a signing certificate or completion report).
7) Store And Share Executed Copies
Save the executed agreement and the platform’s certificate in your contract management system. Share the final copy with all parties. For ongoing confidentiality, if your contract involves sensitive information, keep your signed Non‑Disclosure Agreement on file as well.
What If My Contract Needs Witnessing Or A Deed?
Some contracts require a witness or are intended to be executed as a deed. These scenarios need a little more care with e‑signatures.
Witnessing Requirements
Check whether the law or the document itself requires a witness. If a witness is needed, confirm whether electronic witnessing is allowed in your State or Territory and what the process is (e.g. in‑person vs audiovisual witnessing, IDs to be sighted, special wording).
For general guidance on who can act as a witness, see our overview of who can witness a signature as well as witness signature rules in Australia. If you’re in New South Wales, certain documents can be witnessed remotely under specific rules-our guide to remote witnessing in NSW explains how it works.
Signing As A Deed
Deeds have formalities that differ from ordinary agreements, and those formalities vary by jurisdiction. Before e‑signing a deed, confirm that electronic execution is permitted for your document in the relevant State or Territory and that you’re meeting any witnessing or attestation requirements.
Our explainer on what is a deed in Australian law covers the execution rules and why businesses use deeds (for example, for confidentiality, releases, or documents without consideration).
Company Execution And Section 127
If a company is executing a deed or contract under section 127, make sure the right officeholders sign and that the execution block aligns with the Corporations Act and the company’s constitution. When done properly, section 127 can make enforcement and evidentiary issues simpler, including for electronically executed documents. You can revisit the specifics in our section 127 guide.
Counterparts And Split Execution
It’s common to have parties sign separate counterparts rather than one physical document. This is fine with e‑signing too-just ensure the contract allows counterparts or includes a standard clause. If you’re curious about mechanics and best practice, see our summary on documents being signed in counterpart.
Best Practices To Keep E‑Signatures Enforceable
E‑signatures are powerful, but a little discipline goes a long way to avoid disputes later. Here are practical tips we recommend to clients.
Use A Reputable Platform
Choose an e‑signature provider that offers robust identity checks (e.g. email verification, SMS codes, SSO), a detailed audit log, IP/time stamps, and tamper‑evident files. These features address the legal tests of identity, intent and reliability.
Capture Consent To Electronic Signing
Include a clause in the contract confirming each party agrees to electronic execution and electronic delivery. If you’re not using a platform, secure email confirmation of consent before sending the signing copy.
Check The Right Execution Block For Each Party
Make sure individuals, companies and trustees sign in the correct capacity with accurate names and titles. If a company is signing, confirm whether it will sign under section 127 and set up the execution block accordingly.
Follow Witnessing Rules Precisely
When witnessing is required, organise a compliant workflow: an eligible witness, correct presence (in person or audiovisual if permitted), and any additional certification steps. Keep evidence, including the witness’s details and any prescribed statements.
Lock The Version You Send
Send a final, locked PDF for signature. If changes are needed, issue a new version and clearly label the file to avoid confusion. Avoid having two different “final” versions in circulation.
Store Executed Documents Securely
Keep final copies and the platform’s completion certificate in a safe repository with restricted access. If you collect any personal information during signing (names, emails, phone numbers), ensure your data handling aligns with your Privacy Policy and the Privacy Act.
Use Clear, Tailored Agreements
Strong contracts help prevent disputes, whether signed on paper or electronically. If you’re using templates, have them tailored to your business and Australian law, and review them regularly. When stakes are high, get a focused contract review before you execute.
Plan For Cross‑Border Parties
If a party is overseas, check the signing and witnessing rules in their location too. Consider adding counterparts and governing law clauses and confirming that electronic execution will be recognised where each party operates.
Keep Your Processes Consistent
Create a simple playbook for your team covering version control, approval steps, who can sign on behalf of your company, and when to escalate for legal review. Consistency reduces risk and speeds up execution.
Common Questions About E‑Signing In Australia
Can My Company Sign Everything Electronically?
In most cases, yes-many contracts can be signed electronically by companies, including under section 127 if you meet the formalities. Some documents (certain deeds or statutory forms) may still have paper or specific witnessing requirements depending on the jurisdiction. When in doubt, confirm whether a wet‑ink signature or special process is required for your specific document type.
Do We Need A Witness When E‑Signing?
Only if the law or the contract requires it. Ordinary commercial agreements usually don’t need a witness. Deeds and certain regulated documents often do. If witnessing is required, check whether electronic or remote witnessing is permitted in your State or Territory and follow the procedure precisely, including any required statements by the witness.
Is Clicking “I Agree” Enough?
Often, yes-if the process identifies the person and captures clear intent to accept the terms. For higher‑value contracts or where authority might be questioned, a platform with authentication and audit logs provides stronger evidence. Make sure the person has seen the full contract and that the acceptance is connected to that specific document.
What If We Need Confidentiality Before Signing?
Send a short‑form NDA first and e‑sign it. A tailored Non‑Disclosure Agreement helps you share drafts, financials and IP with less risk while you negotiate the main contract.
Do We Need A Special Clause For E‑Signatures?
It’s good practice to include a clause confirming that the parties consent to electronic signatures, electronic delivery and counterparts. It’s not strictly required in all cases, but it removes doubt and streamlines your process. Many modern templates include this by default.
How Do We Execute As A Deed With E‑Signatures?
Check the deed execution rules in the relevant jurisdiction, confirm whether electronic signing and electronic witnessing are allowed, and set up the right execution blocks. If a company is executing the deed, decide whether to use section 127. Our overview of deeds in Australian law is a helpful starting point.
What If Founders Or Investors Are Signing?
When multiple stakeholders are involved, coordinate execution carefully and consider whether you also need supporting documents like a Shareholders Agreement or Company Constitution. If you’ll be sharing a lot of drafts and sensitive information, keep your NDA on hand and ensure any changes are captured in one clean final for signature. If you’re signing in separate files, make sure the contract allows counterparts-our guide to documents being signed in counterpart explains why this matters.
