How Do I Do an Electronic Signature? A Step-By-Step Guide for Australian Businesses

Electronic signatures have moved from “nice to have” to business as usual across Australia. Whether you’re signing off on a new client contract, onboarding an employee, or updating supplier terms, e‑signatures help you move quickly without chasing paper.

But speed isn’t the only goal. You also want those signed documents to hold up legally and protect your business. The good news is that electronic signatures are recognised under Australian law - provided you follow a few essential rules.

In this guide, we’ll explain what an electronic signature is, when it’s legally binding, and the exact steps to use e‑signatures the right way. We’ll also flag common pitfalls, special scenarios (like deeds and witnessing), and practical tips to minimise risk.

What Is An Electronic Signature In Australia?

An electronic signature (often called an “e‑signature”) is any method of indicating your agreement to a document electronically, instead of signing with a pen. This can include typing your name, drawing a signature on a touchscreen, clicking an “I accept” button, or using a dedicated e‑signature platform.

Australia’s electronic transactions laws (at both Commonwealth and state/territory level) recognise electronic signatures for most transactions. The key is that the method used must identify the signer, show their intention to be bound, and be reliable for the purpose.

A quick note on terminology: some people distinguish between “digital signatures” (which use cryptographic certificates) and “electronic signatures” (a broader category that includes typed names and click-to-accept). In everyday business, either method can be legally effective if the core requirements are met.

If you want to understand how courts and regulators look at signatures generally, it’s helpful to revisit what makes a valid signature - the principles apply whether it’s ink or electronic.

Are Electronic Signatures Legally Binding?

Yes - in most day‑to‑day business scenarios, an electronically signed agreement is just as enforceable as a paper one.

Under the electronic transactions framework, a transaction isn’t invalid simply because it took place electronically. However, three conditions matter:

• Identity and intention: The method must identify the person signing and indicate they intended to sign.
• Consent: All parties must agree to use electronic signatures (this can be express in the contract or implied by conduct).
• Reliability: The method must be as reliable as appropriate for the document’s purpose.

There are also some special rules for companies. Australian companies can execute certain documents electronically under section 127 of the Corporations Act, subject to specific requirements, which we cover in detail in this guide to signing documents under section 127.

A handful of document categories have extra formality requirements (like witnessing, specific wording, or filing). The details vary across states and territories, so it’s important to check before choosing an e‑signature process.

Step-By-Step: How To Use Electronic Signatures Safely

You don’t need to be a tech expert to implement electronic signatures. Follow these practical steps to keep your contracts moving - and enforceable.

1) Pick a Signing Method That Fits the Risk

Common options include:

• Typing your name in a signature field
• Drawing your signature with a mouse, stylus, or finger
• Click‑to‑accept checkboxes or buttons (often used for online terms)
• E‑signature platforms (e.g. solutions that provide audit trails, timestamps, and document integrity)

All can be valid, but the higher the risk or value of the document, the more you should favour a platform that captures a robust audit trail (email addresses, IP/metadata, timestamps, and completion certificates). That evidence is invaluable if the signature is ever questioned.

2) Confirm That E‑Signatures Are Appropriate For The Document

Most business contracts - service agreements, supply terms, employment documents, NDAs, and standard commercial contracts - can be signed electronically.

Some documents, however, attract additional formalities that can differ by jurisdiction, including certain deeds, statutory declarations, and property transfers. Many states now allow electronic deeds and remote witnessing in specific circumstances, but it isn’t uniform nationwide.

If you’re unsure, a quick sense‑check against the latest rules in your state or a short chat with a lawyer will save headaches later.

3) Build Consent Into Your Process

Australian law requires the parties to consent to using electronic communications and signatures. This can be:

• Express: Include a clause stating that electronic signatures and counterparts are acceptable and binding.
• Implied: Parties proceed to sign electronically without objection.

Best practice is to make consent explicit in the document itself. Many modern contracts include a simple clause confirming e‑signing is acceptable and that the electronic version counts as an original.

4) Ensure Identity And Intention Are Clear

Your process should show who signed and that they intended to agree. Ways to strengthen this include:

• Sending the signing link directly to the signer’s email
• Requiring the signer to confirm their name/role
• Using two‑factor authentication (for higher‑risk deals)
• Including a clear acceptance statement near the signature field (e.g. “By signing, you agree to be bound by this agreement”)

E‑signature tools help here by logging access details and locking the document on completion.

5) Execute Correctly For Companies And Deeds

If a company is signing, check how it must execute. Many contracts allow an authorised representative to sign, while others require section 127 execution or a specific authority. When section 127 is used, ensure the signatories and method match the section 127 requirements.

For deeds, rules have modernised in many jurisdictions to allow electronic execution and remote witnessing, but the details vary. If it’s a deed that matters (e.g. a high‑value deal or a long‑term obligation), confirm the formalities for your state or territory before you e‑sign.

6) Store The Final Executed Version Safely

Once all parties have signed, save the fully executed PDF and any completion certificate. Keep backups in at least two places (for example, your document management system plus secure cloud storage). If personal information is included, store it securely and limit access to authorised team members.

Whether your business is exempt from certain privacy laws or not, it’s good hygiene to publish a clear, tailored Privacy Policy if you collect or handle customer data online. Note: there is a small business exemption under the Privacy Act 1988 (Cth) for some businesses under the $3m annual turnover threshold, though many small businesses still need a privacy policy because of what they do (such as health services, credit reporting, or trading in personal information) or because stakeholders expect it.

Which Documents Can You Sign Electronically (And Which Are Tricky)?

In practice, most commercial agreements and everyday business paperwork can be e‑signed:

• Client or customer contracts: Service Agreements, proposals converted to contracts, or Terms of Trade.
• Supplier and contractor documents: Purchase terms, supply agreements, and statements of work.
• Confidentiality documents: A Non‑Disclosure Agreement when discussing sensitive information.
• Employment and HR paperwork: Offers, Employment Contracts, and policy acknowledgements.
• Founder and investor agreements: Many early‑stage documents can be e‑signed, though it’s common to confirm execution formalities for capital raises and company actions.

Documents that can involve extra formality (depending on the jurisdiction and the document’s nature) include certain deeds, statutory declarations, some property instruments, and documents that must be witnessed. It’s not that e‑signatures are “never allowed” - rather, the rules differ across states and depend on the specific document type. If in doubt, check the current requirements or get a quick review from a lawyer.

If your document requires witnessing, you’ll need to consider how the witness will observe the signing and how they will sign. Many states permit remote witnessing for certain documents; however, there are process rules to follow, so it’s wise to confirm who can witness and how in your state by referring to who can witness a signature.

Practical Tips, Risks And How To Prove An E‑Signature

Electronic signatures are efficient and secure when used thoughtfully. Keep these practical points in mind to reduce risk and improve enforceability.

Best‑Practice Tips

• Use reliable tools for important documents: Choose platforms that provide timestamps, completion certificates, and document integrity protections.
• Add a clear e‑signature clause: State that electronic signatures and counterparts are permitted and binding, and that an electronic copy is an original.
• Record the authority to sign: For company signatories, confirm whether the person has authority or if formal company execution is required.
• Version control: Only send final versions for signature, and lock the document after signing.
• Keep your signing workflow simple: Fewer steps and fewer file formats reduce the chance of user error.

Common Risks (And How To Manage Them)

• Identity disputes: Someone later claims, “I didn’t sign that.” Mitigation: send unique links to named signers, use platform authentication, and keep audit trails and access logs.
• Document tampering: Changes made after execution. Mitigation: use platforms that lock documents post‑signing and generate tamper‑evident PDFs.
• Wrong execution method: A company document that required section 127 execution wasn’t signed correctly. Mitigation: decide upfront whether you’re using section 127 or authorised signatories and follow that path consistently.
• Jurisdictional mismatch: Cross‑border deals where the other party’s laws don’t recognise your method. Mitigation: confirm acceptance of e‑signatures in both jurisdictions and adopt a method both sides accept.
• Process gaps: Missing consent or unclear intention in a rush. Mitigation: standardise your templates to include consent language and clear acceptance statements.

How To Prove An Electronic Signature

If a dispute arises, you’ll want to show who signed, when, and what they saw at the time. Useful evidence includes:

• Audit trails and completion certificates from the e‑signature platform
• Email records showing invitation and completion
• IP addresses, metadata, and authentication checks
• Clear contract language that permits e‑signatures
• Final, locked PDF of the executed document

This kind of evidence, coupled with well‑drafted execution clauses, significantly strengthens your position if the signature is challenged.

What About Witnessing And Remote Execution?

For documents that must be witnessed, check whether remote witnessing is permitted for your document type in your state or territory and follow the specific process (for example, real‑time audiovisual observation and particular statements in the document). If you need a refresher on who can act as a witness and what they need to do, revisit who can witness a signature.

Company Execution And Board Resolutions

If your company is executing documents electronically under section 127, make sure you comply with the specific signature combinations and method requirements. When you’re not relying on section 127, confirm the person signing has authority under a delegation of authority, board approval, or the terms of a power of attorney. Getting the mechanics right avoids enforceability disputes and saves time if the document needs to be produced to a bank, investor, or regulator.

Where E‑Signatures Fit Into Your Contracting Toolkit

E‑signatures work best when combined with strong, tailored contracts. For example:

• Your sales process is smoother when your Terms of Trade are clear and easy to accept online.
• Early‑stage discussions are safer when you circulate a straightforward Non‑Disclosure Agreement for quick e‑signature.
• Founder relationships are more stable with a well‑drafted Shareholders Agreement that everyone can sign remotely as the business grows.

Efficient signing is important, but what your documents say is just as critical - the best signing process can’t rescue poorly drafted terms.

Key Takeaways

• Electronic signatures are recognised across Australia and are binding in most business scenarios if identity, intention, consent, and reliability requirements are met.
• Use a signing method that matches the risk. For higher‑value contracts, favour platforms that provide audit trails, timestamps, and tamper‑evident PDFs.
• Not all documents follow the same rules. Certain deeds, witnessed documents, and property instruments have jurisdiction‑specific requirements, and many states now permit electronic deeds and remote witnessing with conditions.
• Execution formalities matter for companies. Decide whether you’re using authorised signatories or section 127 and follow the required method consistently.
• Keep good records of the final executed document and its audit trail - they’re crucial if a signature is ever challenged.
• Combine efficient e‑signing with solid contracts, such as clear Terms of Trade, a practical Non‑Disclosure Agreement, and tailored employment and founder documents, to protect your business from the outset.
• Privacy obligations depend on your specific activities and turnover. Even if you fall within the small business exemption, a transparent Privacy Policy and secure storage practices are good business hygiene and often expected by customers and partners.
