What is Witness Signing?
A Guide for Australian Businesses

Witness signing adds a layer of legal protection to important documents. Understand when it is required, who qualifies as a witness, and how to manage it with electronic signatures.

What Does "Witness Signing" Mean?

Witness signing is the process of having an independent third party observe the signing of a document and then add their own signature to confirm they saw it happen. The witness is not a party to the agreement -- they are there to verify the identity of the signer and confirm the signature was made voluntarily.

In Australia, witness requirements vary depending on the type of document and the jurisdiction. Getting it wrong can render a document unenforceable, so understanding these rules is critical for any business.

Who Can Act as a Witness?

General Documents

For general deeds and agreements, a witness typically must be:

  • Over 18 years of age
  • Of sound mind
  • Not a party to the document
  • Able to identify the signer

Statutory Declarations & Affidavits

These documents require an authorised witness such as:

  • Justice of the Peace (JP)
  • Solicitor or barrister
  • Police officer
  • Medical practitioner, pharmacist, or dentist
  • Public notary

Important

Requirements vary by state and document type. A family member can often witness a general deed, but it is best practice to use an independent witness who has no interest in the transaction.

Electronic Witnessing in Australia

During the COVID-19 pandemic, Australian states introduced temporary provisions allowing documents to be witnessed via audio-visual link (such as video call). Some states have since made these provisions permanent or extended them.

New South Wales

The Electronic Transactions Legislation Amendment Act made permanent provisions for witnessing certain documents via audio-visual link, including statutory declarations and affidavits.

Victoria

Victoria extended its audio-visual witnessing provisions. Statutory declarations, affidavits, and certain deeds can be witnessed remotely under specific conditions.

Queensland

Queensland allows audio-visual witnessing for general powers of attorney, enduring powers of attorney, and certain other documents under the Justice Legislation (COVID-19 Emergency Response) Act amendments.

How Sign & Go Handles Witness Signing

Add Witness Recipients

Add a witness as a separate recipient on any envelope. They receive their own signing link and can only sign after the primary signer has completed their fields.

Full Audit Trail

Every action is timestamped with IP address and geolocation. The audit trail proves who signed, when they signed, and that the witness observed the signing.

Deed-Ready Templates

Our template library includes deed templates with built-in witness fields. AI-powered customisation fills in your company details automatically.

Best Practices for Witness Signing

  1. 1

    Choose an independent witness

    Select someone who is not a party to the document and has no financial interest in the outcome.

  2. 2

    Verify the document type

    Determine whether your document is a deed or simple contract. If unsure, consult a solicitor.

  3. 3

    Check your state's rules

    Witnessing requirements differ between states. What works in NSW may not be sufficient in Queensland.

  4. 4

    Keep records

    Store the signed document with the full audit trail. Sign & Go retains all signing events and metadata automatically.

  5. 5

    Use sequential signing order

    Configure your envelope so the witness signs after the primary signer, reflecting the real-world witnessing process.
