Do You Need a Notary for a Statutory Declaration? Common Mistakes to Avoid

A statutory declaration (“stat dec”) is a formal statement made in writing, affirming that something is true to the best of your knowledge and belief. In Australia, statutory declarations are used for a wide range of legal and administrative purposes—from confirming identity or residency, to supporting visa applications and insurance claims. Once signed in front of an authorised witness, a stat dec carries the weight of a legal document, and making a false declaration can lead to serious penalties under Australian law.

Many people think that a statutory declaration must always be signed in front of a notary public, but in most domestic cases, that’s not necessary. Authorised witnesses—such as Justices of the Peace, lawyers, police officers, or pharmacists—are typically sufficient for declarations used within Australia.

However, if your statutory declaration is intended for overseas use, or to be provided to a foreign authority, or forms part of a broader package of international legal documents, a notary public is often the appropriate and preferred choice to witness your stat dec. Notaries are specially admitted and enrolled as a notary public of a State or Territory Supreme Court and possess all the powers and authorities exercisable by law or custom by notaries public. This includes to verify and certify documents for international recognition, and in many instances, their seal is required by foreign authorities.

Common Scenarios Where You May Need a Notary Public

  • Submitting documents to a foreign government, embassy, or court (e.g. visa applications, residency declarations, affidavits for overseas court cases).
  • Preparing legal documents for international business transactions.
  • Certifying copies of academic qualifications, identity documents, or stat decs for use abroad.
  • Power of attorney documents that will be used in another country.
  • Any declaration that must be followed by an apostille or authentication process through the Department of Foreign Affairs and Trade.

In short, if your statutory declaration is being sent overseas or forms part of a set of documents required by foreign authorities, it needs to be certified by a notary public. Their certification ensures your paperwork will be accepted without issue beyond Australia’s borders.

Common Mistakes People Make When Filling Out a Statutory Declaration

Filling out a statutory declaration might seem straightforward, but small errors can lead to rejection, delays, or even legal consequences. Below are some of the most common mistakes people make—and how you can avoid them.

1. Using the Wrong Template or Format

Each jurisdiction in Australia has its own statutory declaration form—Commonwealth, state, or territory. Using the wrong version or editing the wording can make the declaration invalid. Always download the correct, up-to-date template from the official government website relevant to your purpose. If your stat doc is for overseas use contact our notary in Adelaide and will assist you with a template and notarisation.

2. Leaving Out Essential Details

Missing key information—such as your full legal name, address, occupation, or the actual statement you’re declaring—can render the document incomplete. Be thorough and double-check all required fields before signing.

3. Signing Before You’re in Front of a Witness

This is one of the most frequent errors. A statutory declaration must be signed in the presence of an authorised witness. Signing it ahead of time makes the declaration invalid, and you will need to re-do the declaration.

4. Choosing the Wrong Witness

Not everyone can witness a statutory declaration. Only individuals listed under relevant Commonwealth or State or Territory legislation are authorised to do so—such as JPs, lawyers, police officers, and doctors. A common mistake is assuming a friend or co-worker can sign as a witness when they’re not legally permitted to.

Tip: If your stat dec is going overseas, a notary public is the appropriate and internationally recognised witness.

5. Making False or Misleading Statements

A statutory declaration is a legal document. Knowingly making a false statement is a criminal offence and can lead to fines or imprisonment. Even if an error is unintentional, it can cause problems with the recipient of the statutory declaration such as government departments, legal matters, or visa applications.

6. Using a Statutory Declaration for the Wrong Purpose

In Australia and in many other Countries, stat decs are generally not meant to be used in a Court to declare facts, where an affdiavt is more appropriate. Therefore, be careful not to use a stat dec when an affidavit, contract, or other legal document is required or more appropriate. If you’re unsure, seek advice from a lawyer or notary public.

7. Failing to Keep a Copy

It’s surprising how often people forget to keep a copy of their signed declaration. Always retain a scanned or printed copy in case you need to provide it again later or prove that it was completed.
