If you’re running a business in New South Wales, there will be times when you need to sign something in front of an authorised witness - often at short notice and sometimes under time pressure.
Whether it’s an affidavit for a dispute, a statutory declaration for a government application, or a director signing on behalf of a company, getting this right matters. The NSW Oaths Act 1900 sets the framework for who can witness, how they should witness, and what must appear on the document so it’s legally effective.
In this guide, we’ll walk through the essentials in plain English so you know who can witness your document, what they need to do, and how remote witnessing works in NSW. We’ll also share practical tips to help your team avoid common mistakes and keep your paperwork valid the first time.
What Does The NSW Oaths Act 1900 Cover?
The Oaths Act 1900 (NSW) governs oaths, affirmations, affidavits and statutory declarations in New South Wales. In practice, that means it sets the rules for:
- How people swear or affirm that a document’s contents are true (for example, in an affidavit).
- Who is authorised to witness that process and verify identity.
- What form the witnessing must take (signatures, certification wording, and identification of the witness).
Two common document types you’ll see in business are:
Affidavits
An affidavit is a formal written statement of facts used in court proceedings. The person making the affidavit (the deponent) must swear or affirm the truth of its contents in front of an authorised witness. The witness then signs and states their qualification (for example, “Justice of the Peace”).
Statutory Declarations
A statutory declaration is a written statement that you sign and declare to be true, usually for administrative or regulatory purposes rather than litigation. NSW has a process under the Oaths Act for declarations relating to NSW matters. If you’re preparing a NSW declaration, the witnessing rules are similar to affidavits. For more detail on when to use one and what to include, see Statutory Declarations (NSW).
It’s worth noting that other laws and rules can also apply to how your business signs documents. For example, company execution has its own pathway under the Corporations Act (more on that below).
Who Counts As An Authorised Witness In NSW?
The Oaths Act and related regulations specify which categories of people can witness affidavits and statutory declarations in NSW. Without listing every category, the most common authorised witnesses you’ll encounter in a business context include:
- Justices of the Peace (JPs).
- Australian legal practitioners (for example, a NSW solicitor or barrister).
- Notaries public.
- Registrars and certain court officials.
These professionals are trained (or otherwise authorised) to verify identity, observe the signing, and certify the document in line with the Act.
If you’re unsure whether someone can witness your document, check their status and credentials before you sign. For practical scenarios beyond the Oaths Act (like contracts, deeds or simple forms), the question becomes broader - in many cases any adult witness may suffice unless the law or the document specifies otherwise. For that broader question, our overview on who can witness a signature is a helpful reference.
What About Company Documents Signed Under Section 127?
Witnessing rules intersect with company execution. If a company signs a document under section 127 of the Corporations Act (for example, by two directors, or a sole director/secretary), witnessing is not usually required for the signature to be valid. The law presumes proper execution if section 127 is followed. If your document relies on that method, see our guide to signing documents under section 127.
That said, some documents (like deeds in certain contexts) still require a witness or particular formality. Always check the execution clause and any specific legislation that applies.
What Do Authorised Witnesses Need To Do?
An authorised witness isn’t just a bystander - they have specific duties under the Oaths Act. At a minimum, they should:
- Confirm identity: The witness should take reasonable steps to verify the identity of the person signing (for example, using photo ID). Record-keeping habits vary, but best practice is for the witness to note what they sighted.
- Observe the signing: The witness must actually watch the person sign the document. If pages are initialled, the witness should observe that too.
- Administer the oath or affirmation (affidavits only): The deponent must either swear an oath or affirm that the contents are true. The witness records which one was used.
- Complete the certification: The witness signs, dates, and states their qualification (for example, “Justice of the Peace, Registration No. XXXXX”). For affidavits, they complete the jurat; for statutory declarations, they include the required witnessing statement.
- Deal with attachments: If there are annexures or exhibits, the witness should sign or stamp each attachment and reference them appropriately in the main document.
If the signing involves multiple pages, a good practice is to initial each page (by both the signer and witness) so there’s no doubt about what was approved. For extra clarity, you can also refer to our guide on the legal requirements for signing documents in Australia.
Details That Must Appear On The Document
To avoid rejection by a court or agency, ensure the document includes:
- The deponent/declaring person’s full name and signature, and the date of signing.
- The witnessing statement or jurat in the required form.
- The authorised witness’s signature, printed name, qualification (e.g. “Solicitor”), and any registration number (for example, a JP number).
- Clear references to attachments, with each attachment endorsed by the witness.
Common Mistakes We See
- Signing before meeting the witness, then asking them to “backdate” - this undermines the purpose of witnessing and can invalidate the document.
- Using the wrong form of document (for example, preparing a Commonwealth statutory declaration when a NSW declaration is required, or vice versa).
- Missing the witness’s qualification or JP number on the final page.
- Forgetting to witness all pages or annexures (especially in long affidavits).
Small details make a big difference. If you’re operating across multiple states, be careful with templates - requirements vary and your NSW process may not match another jurisdiction.
Can Documents Be Witnessed Remotely In NSW?
Yes - NSW law allows remote witnessing by audio-visual link, provided strict steps are followed. This is particularly useful for busy founders, remote teams, or when a witness cannot attend in person.
Remote witnessing is available for several document types, including affidavits and statutory declarations, if the procedure is done correctly. For a deeper dive into what the law requires, see remote witnessing in NSW.
Checklist For Remote Witnessing
When using audio-visual link (for example, video conferencing):
- Live audio-visual link: The witness and signer must be able to see and hear each other in real time.
- Verify identity: The witness should verify the signer’s identity (usually by sighting valid photo ID during the call).
- Witness the signing: The witness must see the person sign the document. This can be done by:
- Signing a counterpart; or
- Watching the person sign and then receiving a scanned copy (or electronic copy) promptly.
- Endorse the document: The witness includes a statement that it was witnessed by audio-visual link, with details as required by the Act and regulations.
- Keep records: Best practice is to note the date, time, platform used, how identity was verified, and which counterpart or copy was witnessed.
Remote witnessing doesn’t relax other rules - you still need to use the correct form of affidavit or declaration, and include all the usual witness details. If you are unsure whether your process supports electronic execution, our comparison of wet‑ink signatures vs electronic signatures explains where e-signing is acceptable and where it is not.
Practical Tips For Businesses Getting Documents Witnessed
Getting a document witnessed shouldn’t slow your business down. Here’s how to streamline the process while staying compliant.
1) Choose The Right Document And Jurisdiction
- Confirm whether you need an affidavit (used in court matters) or a statutory declaration (often for administrative purposes).
- Ensure the form is appropriate for NSW. A NSW statutory declaration template differs from a Commonwealth one, and the witnessing list may not be the same.
2) Line Up The Right Witness Early
- Identify whether you need a JP, a lawyer, a notary, or a court officer. In most business contexts, a JP or solicitor will be the most accessible option.
- Confirm availability and whether witnessing will be in person or via audio-visual link.
3) Bring Everything The Witness Needs
- Final version of the document (not a draft). If there are exhibits or annexures, compile and label them.
- Government-issued photo ID for the person signing (and a plan for how identity will be verified if witnessing remotely).
- Any required wording for the jurat/witness statement, and the witness’s details (for example, a JP registration number) ready to include.
4) Plan For Company Execution
If the document is to be signed by a company, consider using section 127 execution where appropriate (for example, by two directors, or a sole director/secretary). It can save time and reduce the need for a witness in some situations. You’ll find the essentials in our guide to section 127.
- Initial every page where relevant (especially for affidavits with exhibits).
- Ensure the date is correct and consistent across all pages and annexures.
- Check that the witnessing statement precisely matches the required form.
6) Remote Or Electronic? Use The Right Method For The Right Document
Some documents allow electronic signing and remote witnessing; others still require wet‑ink signatures or an in-person witness. The rules are document-specific, so it’s important to confirm before you schedule the appointment. For a broader view of what counts as an acceptable signature and when, see what makes a valid signature.
7) Keep A Clean Paper Trail
Store copies of the signed and witnessed documents, the ID details the witness sighted (if appropriate), and any remote witnessing notes (for example, the platform used, the date/time, and counterpart process). If the document will be filed with a court or provided to a regulator, a tidy record saves time and questions later.
8) Train Your Team On The Basics
If multiple team members handle documents, give them a short checklist covering when witnessing is required, how to book a witness, and what to bring. A quick internal guide prevents avoidable errors and rework.
9) Understand How Contract Signing Differs
Not every contract needs a witness. Many agreements are valid without one, and e-signature platforms are perfectly acceptable for most day‑to‑day contracts. The exceptions are where a specific law, regulator or counterparty insists on witnessing or wet‑ink execution. For a refresher on execution rules and pitfalls, review the legal requirements for signing documents in Australia.
10) Use Clear Execution Clauses
For your own templates (for example, settlement deeds or NDAs), make sure the execution block makes it obvious who is signing and how. If your template expects a witness, specify who can act as a witness and include space for their qualification. If you use modern execution options, make that explicit too. If you’re unsure whether your document should be a deed or an agreement, or how witnessing interacts with each, it’s sensible to get tailored advice before you circulate it for signing.
FAQs About Authorised Witnesses In NSW
Do I Always Need An Authorised Witness?
No. You only need an authorised witness when the law or the form requires one - for example, affidavits and NSW statutory declarations. Many everyday commercial contracts don’t require witnessing at all unless they are deeds or a party insists on it.
Can A Co-Worker Or Friend Be A Witness?
For affidavits and NSW statutory declarations, your witness must be in an authorised category (such as a JP, solicitor or notary). For other documents (like some simple agreements), an adult witness may be acceptable - but check the document’s wording and any applicable legislation first.
Is Remote Witnessing Always Valid?
NSW allows remote witnessing by audio-visual link if you follow the prescribed steps. However, not every document is eligible for remote witnessing or electronic signing. If in doubt, confirm your specific document type against NSW requirements or speak with a lawyer. Our overview of remote witnessing in NSW sets out the conditions.
What If A Company Signs Under Section 127?
Company execution under section 127 usually doesn’t require a witness. If you use that pathway correctly, the law provides a presumption of due execution. Where the document must be a deed or the counterparty asks for a witness, follow the requested witnessing method. For section 127 mechanics and options, see section 127.
