How to Verify a Notarised Document Is Genuine
Table of contents

This page is for the person on the receiving end: an employer looking at a certified copy of a degree, a registry checking a power of attorney, a bank presented with a company resolution, a lawyer asked to rely on an affidavit notarised in Australia four years ago.

Verification is possible, and it is more reliable than most people assume — but only because of two things sitting behind the document. The notary's permanent register, and the specimen signature and seal lodged with the Department of Foreign Affairs and Trade.

What you are actually verifying

Be precise about the question, because the answer changes the work.

Is the notary real? Whether the person named holds a notarial appointment.

Did this notary perform this act? Whether the signature and seal are theirs, and whether their register records the act.

Is the document itself true? This one cannot be answered by verifying the notarisation, and the mistake is very common. A notary attests to the copy, the signature, or the oath — never to the truth of the contents. A false statement notarised by a genuine notary produces a perfectly genuine notarial act attached to a lie.

If your concern is the substance, verification of the notarisation will not resolve it. Go to the issuing body — the university, the registry, the company.

Step one: check the appointment

Australian notaries are appointed under the law of their state or territory (in most, by the Supreme Court; in Queensland, by the Archbishop of Canterbury's Court of Faculties), and appointment is a matter of record with that Court. Notarial societies also maintain listings of their members.

You will need the notary's full name and, ideally, the jurisdiction of appointment. Both should appear on the certificate. A notarial certificate that does not identify the notary clearly enough to check them is itself a warning sign.

Step two: contact the notary

This is the most direct route and it is underused. Notaries keep a permanent register of their acts recording what was done, for whom, and on what date. A notary can confirm from that register whether an act matching your document was performed.

Find the notary's contact details independently — through the Court roll, a notarial society listing, or the firm's own published details — and not from the document you are checking. A forged document will happily supply a phone number that reaches the forger.

Be ready for a limited answer. A notary is likely to confirm that an act of a described kind was entered in the register on a date, rather than to discuss the contents. That is usually enough: a forgery will not match the register at all.

Step three: follow the apostille or authentication

If the document was going overseas it will usually carry a DFAT apostille or authentication, and that certificate is itself verifiable.

DFAT issues these after comparing the signature and seal against its specimen records. So the presence of a genuine apostille is meaningful — it tells you an Australian government department has already matched that signature and seal against a specimen.

Apostilles are issued in a standard prescribed form and carry a certificate number and the issuing officer's details. Convention member states maintain a means for a receiving authority to check that a given apostille was in fact issued. If you are the overseas recipient, that route is available to you.

Two cautions. First, only DFAT issues apostilles in Australia — a certificate claiming to be an apostille issued by a notary, an agency, or a translation service is not one. Second, an apostille certifies the signature and seal only. It is not, and has never been, a statement that the document's contents are true.

What genuine notarial documents usually look like

Not a checklist for authentication, but the features whose absence should prompt a closer look:

  • The notary's name, and their description as a notary public
  • The jurisdiction of appointment
  • An impressed or embossed seal, often with an inked overlay
  • The date and place of the act
  • A clear statement of what was done — a copy sighted, a signature witnessed in the notary's presence, an oath administered
  • Pages secured together, often with a ribbon, eyelet or notarial binding, where the act covers a multi-page document
  • The notary's original signature

The wording of a notarial certificate varies by notary and by destination country, often substantially, and unusual wording is not by itself suspicious. Bilingual certificates are routine.

Signs worth a second look

  • The seal is a flat printed image rather than an impression, on a document presented as an original
  • Pages are unbound or the binding has been disturbed
  • The certificate does not say what act was performed, only that the document is "notarised"
  • The certificate claims to certify that the contents are true
  • The document claims a notary issued an apostille
  • The notary cannot be found on any Court roll or society listing
  • Contact details on the document do not match independently published ones
  • The certified copy shows signs the original was altered before copying

The last one matters more than it sounds. A notary certifies that the copy matches the original they were shown. If the original was itself forged, the notarial act is genuine and the document is still worthless.

Common questions

Can I verify a notarisation from years ago? Usually yes. The register is permanent, which is the point of it. Acts remain verifiable even where the notary has since retired.

The notary has died or the firm has closed. What then? Arrangements exist for the custody of a former notary's register. Approach the appointing Court or the notarial society in that jurisdiction for the current position.

Does an apostille prove the document is true? No. Signature and seal only. This is the single most common misunderstanding in this area.

Can I verify a document notarised in another country the same way? The principle is similar but the machinery is national. You would be dealing with that country's notarial authority and its apostille-issuing body, not with DFAT.

Someone sent me a scan. Can I verify it? Partially. You can check the notary's appointment and ask about the register from a scan. You cannot assess the seal impression, binding or original signature — which is why receiving authorities typically insist on the physical document.
