Wrong Certificate Type: Apostille, Authentication or Notarial Act

When an overseas authority says your document carries the wrong certificate, first work out which layer is wrong: the notary's certificate, DFAT's apostille or authentication certificate, or the embassy's legalisation. Each has a different fix. Often the earlier steps still stand and only the last one needs redoing.

Key takeaways

• A document going overseas can carry up to three certificates, from the notary, from DFAT and from an embassy. "Wrong certificate" can mean any one of them.
• DFAT issues either an apostille or an authentication certificate, depending on the destination. If the destination on your request was wrong, or the country's status has changed, the DFAT certificate may be the wrong type.
• DFAT says it cannot advise which one you need. The receiving authority decides, and the HCCH status table tells you whether a country is in the Apostille Convention. Check it on the day.
• If the notarial act itself was the wrong kind, such as a witnessed signature when a certified copy was wanted, the notary step is redone and everything after it follows.
• Do not remove, staple over or alter a certificate. DFAT does not accept altered public documents.

Three certificates, three places it can go wrong

Most people hear "certified" and picture one stamp. A document that travels from Australia can collect three, each from a different office, each saying something different.

1. The notarial certificate. An Australian notary public certifies that a copy matches an original, that you signed in their presence, or that you swore an oath. A notary never certifies that the contents of a document are true.
2. The DFAT certificate. The Department of Foreign Affairs and Trade is the only legalisation authority in Australia. It issues either an apostille (for countries in the Hague Apostille Convention) or an authentication certificate (for countries outside it). Both confirm the signature and seal on the document, such as the notary's, and nothing about the contents.
3. Embassy legalisation. Only for countries outside the Convention: after DFAT's authentication, that country's embassy or consulate in Australia adds its own endorsement.

So when a foreign ministry, bank or university says "this is not what we asked for", ask them which of the three they mean. The answer decides whether you go back to the notary, to DFAT or to the embassy.

When the DFAT certificate is the wrong type

DFAT applies whichever certificate fits the country you name on its legalisation request form. It says plainly that it cannot tell you which one you need; that is a question for the receiving authority. Four situations produce the wrong one.

The destination on the form was wrong. A document prepared for a job in one country is later sent to another. An apostille issued for use in the United Kingdom is the wrong certificate for the United Arab Emirates, which, as of our last check, is not a Convention member and expects DFAT authentication followed by legalisation at its mission.

The country's status changed between the two steps. Countries join the Convention, and the date it takes effect for them can be months after they sign up. On our last check of the HCCH table, Thailand had acceded on 30 June 2026, with the Convention coming into force for it on 28 February 2027. Until that date, a Thai authority would still expect authentication and Thai embassy legalisation; after it, an apostille. Viet Nam's date was 11 September 2026, Canada's 11 January 2024 and China's 7 November 2023. A document legalised the old way just before one of those dates, or apostilled too early, can be caught in between. Confirm with the receiving authority which form it accepts during a changeover.

The two countries are not in a Convention relationship with each other. When a country joins, existing members may object, and the Convention then does not operate between that pair. The HCCH table lists these objections in its notes. It is rare for documents leaving Australia, but it is the reason to read the notes and not only the list of names.

The receiving office wants more than the Convention requires. Some offices ask for an embassy endorsement even from a Convention country, out of habit or under an internal rule. The Convention says an apostille is enough between members, but the practical fix is still to ask the office, in writing, what it will take.

Can DFAT replace the wrong certificate?

DFAT places its certificate on the original document you supply, and it verifies the signature and seal against its records. That has two consequences. You cannot convert an apostille into an authentication certificate yourself, and you should not remove one: DFAT does not accept public documents that have been altered, and a certificate that has been detached and re-stapled is exactly that.

What you can do is ask DFAT, before lodging again, whether it will issue the correct certificate on the same document or whether it needs a fresh original or a fresh notarised copy. Registry certificates, court documents and police checks can be reordered from the issuer if needed; DFAT's page on documents it can legalise lists what it accepts. A notarised document can usually be notarised again from the same original. Treat it as a new request unless DFAT tells you otherwise, and put the correct destination country on the form this time. Our page on DFAT authentication explains the non-Convention route in more detail.

When the notarial act is the wrong kind

This is the more common problem, and it has nothing to do with DFAT. The apostille over a wrong notarial act is perfectly valid; it just verifies an act nobody wanted. An apostille confirms the notary's signature and seal. It does not check whether the notary did the right thing for your purpose.

Problems with the notarial act itself

A certified copy was wanted, a signature was witnessed. Certifying a copy means the notary compares a copy against the original they are holding and certifies that it matches. Witnessing a signature means the notary watches you sign and certifies who signed. If the requirement was a certified copy of your degree and you signed a declaration about your degree instead, the act does not satisfy it, and the reverse is also true. The fix is a fresh notarial act from the same original.

The authority wanted the contents certified as true. Some overseas authorities ask for a certificate that the statements in a document are correct. An Australian notary cannot give that. The usual substitute is a declaration or affidavit in which you state the facts and the notary witnesses your signature or administers the oath. The truth of the contents remains your statement, with the consequences a false declaration carries. Confirm with the receiving body that this satisfies it before going further.

The authority wanted the issuing body's own copy. Universities, births, deaths and marriages registries and professional boards issue their own certified extracts and replacement certificates. Some overseas ministries accept nothing else. A notary's copy cannot stand in for this, and no certificate added later will turn it into one. Order from the issuer.

Problems with wording, translations and forms

A university copy had "true copy" wording. This one is specific to DFAT. For a notarised copy of an Australian university degree or transcript, DFAT requires the university to verify the record, and the notary's certificate must state that the original record has been verified with the issuing institution. A plain true-copy certificate does not meet that rule. See certified copies of a university degree.

The translation was certified, not the document, or the other way round. A translated document can carry certificates on the original, on the translation and on the translator's statement. Instructions often say "certified translation" while meaning something more exact. For DFAT, a translation needs a NAATI certified or recognised translator's name, signature, NAATI seal with practitioner ID and the date on every page. Ask which item must be certified and at what point in the chain. See what to do when a translation is rejected.

The authority had its own form. Banks, pension funds, foreign courts and some embassies publish forms with wording they will not change, such as a life certificate or a specimen signature card. A general notarial certificate, however correct, does not fill in their form. Take the form to the notary unsigned and have the notarial part completed on the form itself. Our page on proof of life certificates covers the most common case.

A JP certified it. A Justice of the Peace is a free witness for Australian purposes. A JP's certification is not accepted overseas and DFAT will not legalise it; for TAFE documents DFAT says so in terms. If the document is leaving Australia, the notary step is usually needed.

Get the requirement in writing before you redo anything

Vague instructions cause most of these problems, so replace them with specific answers before paying for a second round. Ask the receiving authority, by email so you have their words:

• Do you need a copy certified, or a signature witnessed?
• May an Australian notary certify the copy, or must it come from the issuing body?
• After notarisation, do you need an apostille, or DFAT authentication and legalisation at your embassy?
• If there is a translation, which part must be certified, and at which step?
• Do you have a form that must be used?

Show the notary that email at the appointment. A notary can shape the certificate to the stated requirement only if they can see it. Then follow the chain in order:

1. Fix the earliest wrong step first. If the notarial act was wrong, nothing after it can be kept.
2. Bring the original, not a scan or an earlier copy. A notary must sight the original.
3. Lodge with DFAT naming the correct destination, and keep a copy of the request form.
4. Complete the embassy step if the country is outside the Convention.
5. Send the original, and keep a full scan of every page and certificate.

If the fault was the notary's, for instance a certificate that did not follow instructions you had given in writing, raise it with the notary. If it was a change in the country's status or a change in the destination, it is no one's error, and the fix is simply the correct certificate. Our apostille and authentication page sets out how the Australian steps fit together.

Here is an illustration, not a real case

An engineer in Brisbane has her degree notarised with university verification and apostilled for a job offer in Singapore. The offer falls through and a firm in Dubai hires her instead. The Dubai firm says the apostille is not what it needs. She asks DFAT whether a new certificate can be issued; the notarial certificate still stands because it was correct, so she lodges the notarised copy again naming the United Arab Emirates, receives an authentication certificate, and takes the document to the UAE mission for legalisation. Before any of this she checks the HCCH table, because the position can change.

In short

Find out which certificate is wrong before redoing anything. If DFAT's certificate is the wrong type, the notarial act usually survives and only the DFAT step, with the right destination, and any embassy step follow. If the notarial act is the wrong kind, start again from the notary with the original. Get the requirement in writing and show it to everyone in the chain. Our document notarisation page covers the first step.
