Electronic signatures are now the norm for commercial credit applications — delivered by email, signed via DocuSign, HelloSign, Adobe Sign, or equivalent, and returned without paper. For most trade creditors, the convenience has been significant. But when a debt goes bad and the signed credit application is the primary evidence of the contractual relationship, the validity of the electronic signature becomes important.
The legislative framework
Australia does not have a single national electronic signature law. The Electronic Transactions Act 1999 (Cth) applies to Commonwealth matters and has been substantially adopted in equivalent state legislation. Under these Acts, an electronic signature is valid if: the method of signing identifies the signatory and indicates their intention to be bound; the method is either consented to by all parties or is otherwise reliable; and the document is appropriately retained.
This means that a simple typed name at the bottom of a PDF, a scanned handwritten signature, a click-to-agree process, or a platform-generated digital signature can all satisfy the legal requirement, provided the conditions above are met.
What makes an electronic signature more reliable
The weakest form of electronic signature is a typed name with no associated verification — it is difficult to establish that the person named actually signed the document. Stronger forms include:
- Platform-generated signatures (DocuSign, Adobe Sign) with an audit trail showing the IP address, timestamp, and email verification used to sign.
- SMS-verified signatures where a one-time code confirms the signatory's mobile number.
- Identity-verified signatures that require the signatory to authenticate with a government-issued ID.
In a recovery or dispute, the audit trail provided by a platform-based signature is significantly stronger evidence than a typed name. If a debtor denies signing a credit application, an audit trail showing the document was accessed from their IP address at a specific time, with their email address verified, makes denial difficult.
Personal guarantees and higher-risk documents
Personal guarantees signed electronically are generally valid under the same framework, but require particular care. Some jurisdictions and some guarantee wordings may have specific execution requirements. Courts have generally upheld electronically signed guarantees where the signatory's identity and intention can be established, but the strength of that evidence matters in any challenge.
Deeds — legal instruments that require execution as a deed — have historically required specific formalities that electronic signatures may not satisfy. Whether a credit agreement or guarantee needs to be executed as a deed depends on its content and the applicable state law. If your standard credit agreement is structured as a deed, seek legal advice on whether your electronic execution process is valid.
Practical checklist
- Use a platform that generates a full audit trail for all credit applications and guarantees.
- Retain the audit trail alongside the signed document.
- Ensure your credit application wording is clear that the signatory is signing on behalf of the business and (if applicable) personally as guarantor.
- Review whether your document is structured as a deed, and if so, seek advice on execution requirements.
