Who Can Witness Documents in Western Australia?

In Western Australia, the right witness depends on the document. WA has a long list of authorised witnesses for statutory declarations, a shorter list for affidavits, and its own rules for enduring powers of attorney. Documents going overseas usually need a notary public, whose signature DFAT can apostille. In regional WA, knowing who else may witness saves long trips.

Key takeaways

• WA's list of people who can witness a statutory declaration is long and covers many professions, which helps outside Perth.
• An affidavit has a shorter list of authorised witnesses, and courts add their own rules.
• An enduring power of attorney in WA has its own witness requirements. Check the current guidance before you sign.
• Justices of the Peace are free volunteers. A JP's signature cannot be apostilled for use overseas.
• For documents going abroad, use a notary public, then DFAT if an apostille is asked for.

Why the witness list matters so much in WA

Western Australia covers a third of the continent, and many people live hours from a courthouse, a JP or a notary. Mining and fly-in fly-out rosters, pastoral stations and remote communities make it hard to be in the right town on the right day. That is why it pays to know exactly who may witness your document before you travel, rather than assuming only a JP or lawyer will do.

WA law sets out who may witness each kind of document, and the lists differ. The WA Department of Justice publishes the current lists and forms. The body receiving your document can also ask for more than the law requires, so read its instructions too.

Who can witness a WA statutory declaration?

WA's list of authorised witnesses for statutory declarations is long. Alongside Justices of the Peace and lawyers, it includes many registered professionals, public servants of certain levels, police officers and others. The witness must see you sign, check your identity, and complete the witness section with their name and their qualification as a witness.

That breadth is useful in regional WA: the witness you need may already be in your town, at the health clinic, the school, the police station or the shire office. Check the current list to confirm the person's role qualifies. If the receiving body is a Commonwealth agency, such as Home Affairs, it will usually want a Commonwealth statutory declaration instead, which has its own form and list of approved witnesses. The Attorney-General's Department publishes the Commonwealth form and witness list, and our guide to who can witness a statutory declaration compares them.

Who can witness an affidavit in WA?

An affidavit is sworn or affirmed evidence, usually for a court. WA's list of people who may witness an affidavit is shorter than the statutory declaration list and includes Justices of the Peace, lawyers and certain court and public officers. Courts also have rules on the form of affidavits, annexures and exhibits, and apply them strictly.

If your affidavit is for a WA court, follow the court's instructions, and ask your lawyer if you have one. If it is for a court overseas, a notary is usually the right witness, because the foreign court needs an act it can recognise, and DFAT can then authenticate or apostille it. See our guides to statutory declarations and affidavits and notarising an affidavit.

Who can witness an enduring power of attorney in WA?

An enduring power of attorney lets someone manage your financial affairs, including if you lose capacity. WA sets its own requirements for how it is made and witnessed, including how many witnesses are needed, who may act as one, and who is excluded, such as the attorney. The rules exist to protect people at a vulnerable time, and a document witnessed incorrectly may fail when it is needed most.

WA's forms and rules for enduring powers of attorney can change, so read the current form and guidance from the WA Office of the Public Advocate or the Department of Justice before you sign, and speak to a lawyer if your situation is complex. Enduring powers of guardianship and advance health directives have their own forms and rules. Our guides to powers of attorney and enduring guardianship forms give the general picture.

What does a WA Justice of the Peace do?

A Justice of the Peace in WA is a volunteer appointed to serve the community. JPs do not charge for witnessing documents. They witness statutory declarations and affidavits, certify copies of documents they have sighted, and some also sit in court. A JP checks your identity and watches you sign, but does not give legal advice or confirm that what you have written is true.

Many WA JPs are available by arrangement, and some towns have regular JP sessions. For documents that stay in Australia, a JP is often all you need. For documents going overseas, a JP cannot replace a notary, because DFAT cannot apostille a JP's signature. Our guide to notaries and JPs explains where a JP's role ends.

Which WA document needs which witness?

The table gives the usual answer. The receiving body's instructions always come first.

Document	Usually witnessed by	What to check
WA statutory declaration	Anyone on WA's authorised witness list, including JPs	That the witness's role is on the current list
Commonwealth statutory declaration	Anyone on the Commonwealth list of approved witnesses	That the receiving body wants the Commonwealth form
Affidavit for a WA court	A JP, lawyer or other authorised witness	The court's rules on form and exhibits
Enduring power of attorney	The witnesses WA's current rules require	The current form and Public Advocate guidance
Certified copy for an Australian body	A JP or another person the body accepts	The body's own list of certifiers
Document for use overseas	A notary public, then DFAT if asked	What the foreign body wants: notarisation, apostille or both

When do you need a notary in WA?

You need a notary when a document is going overseas and the foreign body wants it notarised or apostilled. In WA, notaries are experienced lawyers appointed by the Supreme Court of Western Australia. They witness signatures, certify copies, administer oaths and prepare notarial certificates for use abroad, and keep a permanent record of each act.

Common examples are powers of attorney for property overseas, affidavits for foreign courts, certified copies of passports and degrees for overseas employers, and company documents for foreign registries, which come up often for WA's resources and export businesses. After the notary signs, DFAT adds an apostille or authentication if the foreign body asks. Our guides to notary public in Perth and which documents can be apostilled cover the practical steps.

Can documents be witnessed remotely in WA?

WA allows some documents to be signed and witnessed electronically or by audio-visual link, under conditions set by WA law, and the arrangements have changed since 2020. Whether a document qualifies depends on its type, and the receiving body must also be willing to accept it.

For documents going overseas, the foreign body decides whether it accepts a remotely witnessed act, and many do not. That matters in regional WA, where a video appointment is tempting. Ask the foreign body first. Our remote notary guide explains what to ask, and notaries in regional Australia covers planning a visit.

How do you prepare to have a document witnessed in WA?

1. Identify the document type and where it is going.
2. Read the receiving body's instructions for the form and the witness it wants.
3. Check the current WA list to confirm your witness's role qualifies.
4. Leave the document unsigned until you are in front of the witness.
5. Bring original photo identification and the originals of anything to be certified.

What are the common mistakes with WA documents?

Most refused documents fail for simple reasons. The witness's role was not on the list for that document, the declaration was on the WA form when the Commonwealth form was needed, the document was signed before the appointment, or a JP certified a copy that was going overseas. Each of these means starting again, which in regional WA can mean another long trip. A few minutes with the checklist below usually avoids them.

What does this look like in practice?

Here is an illustration, not a real case. Jake works fly-in fly-out from Perth to a mine in the Pilbara. He needs a WA statutory declaration for a vehicle matter, and a power of attorney so his father can sell a house in Ireland.

He checks the WA witness list and finds that the registered nurse at the site medical centre qualifies to witness his statutory declaration, so he has it done on shift. The Irish solicitor wants the power of attorney notarised and apostilled and will not accept a remote act, so Jake books a notary in Perth for his rostered days off, and then sends the document to DFAT.

In short

In Western Australia, match the witness to the document: WA's long list for statutory declarations, a shorter list for affidavits, and WA's own current rules for enduring powers of attorney. Use a notary for documents going overseas. In regional WA, check the full witness list before you travel, and ask overseas bodies whether they accept remote witnessing.
