Can your business accept an electronic signature in Australia

You do not need to look far to come across this question. A customer returns your service agreement with their name typed into the signature block. A supplier asks you to click "I agree" in an online portal before their first delivery. A director wants to sign the company's new lease from their phone. In each case, the same doubt nags: does it count, or does a contract only really exist once a pen touches paper?

The good news is that electronic signatures are generally valid in Australia, and have been for more than two decades. The catch is that validity is not automatic. It turns on how the signature was created, whether the person receiving it was happy to accept it electronically, and whether any law governing the particular document stands in the way. This article explains what an electronic signature is, the test the law applies to it, and the everyday situations where it works, where it needs care, and where paper is still required.

What counts as an electronic signature?

An electronic signature is any electronic means used with the intention of being a person's signature. The definition is deliberately broad. A typed name at the end of an email can be a signature. So can ticking a box on a website, inserting a scanned image of a handwritten signature into a PDF, or writing in an email that the email itself is to be taken as the signature.

No specialist software is required. Everyday tools such as DocuSign, Adobe Sign or a simple "type your name here" PDF all produce electronic signatures. At the more secure end of the spectrum, a digital signature uses encryption, a technology known as asymmetric cryptography, to tie the signature cryptographically to the person signing. Digital signatures generally need separate software and are usually reserved for high-value or high-security transactions, but they are simply one type of electronic signature.

When is an electronic signature valid?

The starting point is s 8 of the Electronic Transactions Act 1999 (Cth) (the ETA): a transaction is not invalid because it took place wholly or partly by electronic communication. Every state and territory has an equivalent Act in substantially similar terms, including the Electronic Transactions Act 2000 (NSW).

Validity is, however, conditional. Where a law requires a signature, s 10 of the ETA says an electronic signature meets that requirement only where:

• Identification: a method is used that identifies the person signing and indicates their intention in respect of the information communicated;
• Reliability: the method is as reliable as appropriate in the circumstances, or can be proven in fact to have identified the signer and their intention; and
• Consent: the person to whom the signature is given consents to it being given electronically.

Section 9 of the NSW Act mirrors those three limbs. Notice what the consent point means in practice: it is the recipient's consent that counts. If you send a contract to a customer and they sign it electronically, your willingness to accept the electronic signature is part of what makes it valid. Both sides need to be comfortable with electronic signing before a signature can be relied on.

One further point is worth making. Many everyday contracts do not need a signature at all. A binding agreement can be formed by an exchange of emails or by conduct, and Part 2A of the ETA confirms that its provisions apply to contracts formed electronically. The signature question really bites where a law, or the document itself, requires one, such as with a deed or a document that must be witnessed.

Scenario: a customer or supplier signs your agreement online

Most business-to-business and business-to-consumer agreements can be signed electronically. If you send a customer a service agreement and they type their name or tick a box to accept, that is generally a valid signature, as long as the method identifies them, indicates their intention, and both sides are content to proceed electronically.

The reliability limb deserves the most thought. "As reliable as appropriate in the circumstances" is a flexible test. For a low-value supply arrangement between parties who have traded together for years, a typed name in an email reply will usually be reliable enough. For a large or complex deal, or where you have genuine doubts about who is signing, a platform that verifies identity, records what the signer did and produces an audit trail will be far harder to challenge. The more that is at stake, the more robust the method should be.

Scenario: your company executes a contract or a deed

Company documents have their own rules. Part 1.2AA of the Corporations Act 2001 (Cth) allows documents required or permitted to be signed under the Act to be signed electronically. Under s 110A, a person may sign an electronic form of a document if the method identifies them and indicates their intention, and is as reliable as appropriate in the circumstances, or is proven in fact to have done so.

For companies, s 127 sets out how documents are executed, including by two directors, or by a director and a company secretary. Since the Corporations Amendment (Meetings and Documents) Act 2022 (Cth) commenced, the signing requirements under s 127 can be satisfied electronically, and s 127(3A) allows a company to execute a deed under s 127(1) without a witness and without paper, parchment or vellum. These changes began as temporary measures during the COVID-19 pandemic and were made permanent in 2022.

Note one difference from the ETA. Under s 110A, there is no separate consent limb: the test is identification and reliability. A company document signed by the right people using an appropriate electronic method is not invalid merely because the recipient did not separately consent to electronic execution.

Scenario: the document must be witnessed

Some documents require more than a signature. Wills, enduring powers of attorney, statutory declarations and affidavits must generally be signed and witnessed, and the witness traditionally had to be physically present. An electronic signature on its own cannot satisfy a witnessing requirement: someone still has to observe the signing and attest to it.

The law here has moved in recent years. In NSW, Part 2B of the Electronic Transactions Act 2000 (NSW), inserted by the Electronic Transactions Amendment (Remote Witnessing) Act 2021 (NSW), permanently allows a document to be witnessed by audio visual link, provided the witness observes the signatory sign in real time, attests to the signature, and endorses the document with a statement of how it was witnessed. Other states and territories have their own arrangements, some permanent and some temporary, so the position depends on which state's law governs the document.

For companies, the position is different again: a company executing a deed under s 127(1) of the Corporations Act does not need a witness at all, thanks to s 127(3A).

Scenario: a specific law carves the document out

Even where the general rules would allow an electronic signature, a specific law can override them. The Electronic Transactions Regulations 2000 (Cth) list laws of the Commonwealth to which parts of the ETA do not apply. Where an item covers a document, an electronic signature will not satisfy the statutory requirement and the paper version must be used. The current list includes certain documents under family assistance legislation, the Commonwealth Electoral Act, customs provisions and shipping registration.

State regulations contain similar carve-outs. The lesson is practical: before assuming an electronic signature will do, check whether the specific law governing the document says otherwise. If the document sits in a regulated area, or must be filed with a court or government body, take particular care.

Do you need a lawyer to accept an electronic signature?

For the routine case, no. A straightforward service agreement signed through a standard platform, with both parties comfortable proceeding electronically, is well within ordinary business practice. Most small businesses can handle these day to day without any professional input.

There are situations, though, where a short conversation is worthwhile. If the document is a deed, is governed by a law with its own signature rules, must be witnessed, involves a high-value transaction, or will be signed by a company rather than an individual, the cost of getting execution wrong can far exceed the cost of a check. An invalid signature can mean a contract is unenforceable, a deed is void, or a dispute later turns on whether anyone validly signed at all.

A lawyer can confirm whether the law governing your particular document permits electronic signing, advise on how reliable the method needs to be, and set up an execution process that will hold up if a counterparty later challenges the deal. Most firms, including Artificer Legal, offer an initial consultation, and a five-minute enquiry will normally tell you quickly whether your situation is straightforward or needs proper attention.

So, can you accept an electronic signature?

In most cases, yes. An electronic signature is any electronic method used as a personal signature, from a typed name to a cryptographically secured digital signature. It is valid where the method identifies the signer and shows their intention, is reliable enough in the circumstances, and the recipient consents. The exceptions are where a specific law excludes electronic communication for that document, where a signature must be witnessed and no permitted remote witnessing arrangement applies, and where the document falls outside the technology-neutral rules that now cover company documents.

The practical rule for your business is simple. Check what kind of document you are dealing with, use a method proportionate to what is at stake, and keep a record of how the signature was made. Where a deed, a witnessed document or a high-value deal is involved, a quick check with a lawyer is cheap insurance against a signature that later fails.
