As an increasing number of businesses move online, we have seen an equal increase in the need for businesses to transact quickly and efficiently online. A commonly asked question is whether a business can accept an electronic signature. We aim to answer this question and provide some general guidance on what is and is not acceptable as an electronic signature.
Regulatory Framework
The Commonwealth’s Electronic Transactions Act 1999 and the Electronic Transactions Regulations 2000 cover the use of electronic signatures. There is also equivalent state legislation such as the Electronic Transactions Act 2000 (NSW). These Acts recognise that a transaction is not invalid because it took place using one or more electronic communications.
Recently, Federal and certain State governments have passed legislation to permanently allow for the electronic execution of company documents. This includes the Corporations Amendment (Meetings and Documents) Act 2022 (Cth) (CA Act) and Electronic Transactions Amendment (Remote Witnessing) Act 2021 (NSW) in New South Wales.
What is an Electronic Signature?
An electronic signature refers to any electronic means that have the purpose of being a personal signature.
This can include:
- typing a name;
- ticking a box;
- inserting a scan of a person’s signature into a document; or
- stating in electronic communication that the communication itself is to be taken as the signature.
Electronic signatures can also include a digital signature. A digital signature is a type of electronic signature that relies on encryption (known as asymmetric cryptography) to authenticate messages. A digital signature usually requires the purchase of a program or software and is typically used in high-security and high-value transactions.

The general rule is that an electronic signature does not invalidate a transaction. Importantly, an electronic signature must fulfil certain requirements to be valid. These include the following.
Identification
The electronic signature must identify the person signing the document and their intention to sign the document.
Reliability
The method of electronic signing must be reliable in the circumstances generating the electronic communication.
Consent
The person receiving the electronic communication must consent to the use of the electronic signature to execute the contract.
Note that for documents under section 110A(2) of the CA Act, consent is no longer strictly required. Importantly, you must ensure to identify parties and do so reliably.
Exclusions
There are several laws excluding the law of electronic communication from operating. If this applies, you cannot use an electronic signature instead of a standard original signature on paper.
For example, the Corporations Act excludes the use of electronic signatures. Company directors and secretaries must execute paper versions of any document or agreement requiring their signature. Electronic signatures are also impracticable where a person’s signature requires a witness. While there is no issue with a person electronically signing the document, electronic communication cannot satisfy the requirement that a person witnesses the signature.
Common Use
With the changing landscape due to COVID-19, the presence and use of electronic signatures have allowed businesses to continue to operate. There are numerous practical examples of electronic signatures improving a business’ efficiency in its day-to-day operations. Consumers and businesses use electronic signatures to enter into supply and service agreements. For example, purchasing groceries, legal services or doing their banking online.
