How to Verify an Australian Apostille

An Australian apostille is issued by DFAT, the only competent authority for apostilles in Australia. To verify one, read its standard numbered fields, note the apostille number and date, and confirm them with DFAT using the verification method it currently offers. It proves a signature and seal are genuine, not the contents.

Key takeaways

• In Australia, only DFAT issues apostilles. An apostille said to come from anyone else is not an Australian apostille.
• Every apostille has the same standard fields, including a unique number and a date.
• Verify it with DFAT, using the method DFAT publishes on its current guidance, quoting the number and date.
• An apostille confirms the signature, capacity and seal of the official or notary who signed the document. It says nothing about the content.
• If the apostille has been separated from the document it was attached to, it no longer proves anything about that document.

What does an Australian apostille look like?

An apostille follows a standard model set by the Hague Apostille Convention, so apostilles from all member countries share the same structure. The certificate is headed "Apostille", usually with a reference to the Convention, and contains ten numbered items: the country, the name of the person who signed the document, the capacity in which they signed, the seal or stamp the document bears, the place and date of certification, the authority certifying, the apostille number, and the certifying authority's seal and signature.

An Australian apostille names Australia as the country and DFAT as the certifying authority, and is attached to the document, or to the notarial certificate, in a way that keeps them together. The underlying document may be a public document, such as a registry certificate, or a private document with a notary's certificate on it. Our guide to how the Apostille Convention works explains the background.

How do you verify it?

Start with the apostille itself. Check that it names Australia and DFAT, that the name and capacity in items 2 and 3 match the signature on the document or notarial certificate, and that it is still firmly attached to the document. Note the apostille number and the date of issue.

Then confirm those details with DFAT, which keeps records of the apostilles and authentications it issues. DFAT's guidance on Smartraveller sets out how receiving authorities and others can verify an Australian apostille, and the method can change, so follow the current guidance rather than an old instruction. Some countries also run online registers for their own apostilles; whether and how an Australian apostille can be checked online depends on DFAT's current arrangements.

What does an apostille actually prove?

This is the point most often misunderstood. An apostille confirms that the signature on the document is genuine, that the person who signed it held the capacity stated, such as a registry officer or a notary, and that any seal or stamp is genuine. It does not confirm that the document's contents are true, that the document is legally valid, or that it is the right document for the purpose.

So a verified apostille on a notarised power of attorney proves that an Australian notary genuinely signed the notarial certificate. It does not prove the power of attorney is effective under foreign law. For that, the receiving body applies its own law. Our guide to verifying a notarised document covers the notarial layer beneath the apostille.

What are the warning signs?

Most apostilles are exactly what they appear to be, but a few signs call for a closer look. An apostille that names a certifying authority other than DFAT for an Australian document is not an Australian apostille. One that is loose, stapled on afresh, or attached to a document with signs of unbinding may not belong to that document. Details in items 2 and 3 that do not match the signature on the document, or a number and date DFAT cannot confirm, are also reasons to question it.

Be cautious, too, of documents apostilled by anyone claiming to be a private "apostille service" that issues its own certificates. Private services may help people lodge documents with DFAT, but the apostille itself must come from DFAT.

Apostille or authentication certificate?

DFAT issues two kinds of certificate. For countries that are parties to the Hague Apostille Convention, it issues an apostille. For countries that are not, it issues an authentication certificate, which the destination country's embassy or consulate then legalises. The two look different and serve different purposes. If you receive an authentication certificate where you expected an apostille, or the reverse, check which the destination needed; our guide to the right certificate type explains what to do.

What about foreign apostilles on documents used in Australia?

A foreign apostille is verified with the competent authority of the country that issued it, not with DFAT. Many countries publish how to verify their apostilles, and some run online registers where you can check an apostille by its number and date. Australian bodies that receive foreign documents, such as courts or registries, can verify apostilles the same way. Our guide to foreign documents in Australia explains when an apostille is needed at all.

Why would someone need to verify an apostille?

Most receiving bodies accept apostilles at face value, because the whole point of the Convention is that a single standard certificate can be trusted between members. Verification becomes important where something is at stake or something looks wrong: a large property transaction, a court case, a document that has passed through several hands, or an apostille whose details do not quite match. Banks, notaries and registries abroad sometimes verify as a matter of routine for high-value matters.

If you are the person who obtained the apostille, you can help by keeping a record of when and how you lodged the document with DFAT, and by sending the receiving body a clear scan of the apostille in advance if it asks. That makes any verification quicker.

What if the apostille contains an error?

Occasionally an apostille carries a mistake, such as a misspelled name in item 2 or the wrong capacity in item 3. If you notice an error before the document is used, contact DFAT with the apostille number and date and explain the problem; it may be able to reissue or correct it. Do not alter the apostille yourself, because any change will make it look tampered with. If the error is in the underlying document or notarial certificate instead, that must be corrected first, and a new apostille issued for the corrected document.

Does an apostille expire?

An apostille itself does not usually carry an expiry date. But the receiving body may want the underlying document to be recent, for example a birth certificate or police check issued within a set period, and that requirement is not affected by the apostille. An old apostille on a recently reissued document is not possible; the new document needs its own apostille. Our guide to documents that are too old for an overseas body explains the common rules.

How do you verify an Australian apostille?

1. Check the certificate names Australia and DFAT, and that it is firmly attached to the document.
2. Compare items 2 and 3 with the signature on the document or notarial certificate.
3. Note the apostille number and date of issue.
4. Confirm them with DFAT, using the verification method on its current guidance.
5. Remember what it proves: the signature and seal, not the content or validity.

What does this look like in practice?

Here is an illustration, not a real case. A lawyer in Portugal receives a power of attorney from a client in Brisbane, notarised by a Queensland notary and bearing an Australian apostille. The Portuguese notary asks the lawyer to confirm the apostille before relying on it.

The lawyer checks that the apostille names Australia and DFAT, that items 2 and 3 name the Queensland notary whose signature appears on the notarial certificate, and that it is firmly attached. The lawyer then follows DFAT's published verification method, quoting the number and date, and receives confirmation. The Portuguese notary proceeds, assessing the power of attorney itself under Portuguese law.

In short

To verify an Australian apostille, check that it names Australia and DFAT, that the signatory matches the document, and that it is firmly attached, then confirm its number and date with DFAT using its current verification method. An apostille proves the signature, capacity and seal on the document are genuine; it does not prove the contents are true or that the document is valid.
