Full Birth Certificate or Extract: Which to Use Overseas

Use a full birth certificate. Most overseas authorities want the version that records your parents and registration details, which is the standard certificate Australian registries issue for official use. DFAT can still apostille an older extract of birth entry, but an apostille does not make an extract acceptable to an authority that asked for a full certificate.

Key takeaways

• A full birth certificate is the standard certified certificate from a state or territory registry, with your parents' and registration details.
• An extract of birth entry is an older, shorter document that many people born decades ago still hold. It is no longer accepted for identification in Australia.
• DFAT can legalise birth certificates including extracts and commemorative certificates, but the receiving authority decides which version it accepts.
• If an authority asks for a "full", "long-form" or "unabridged" certificate, order a new full certificate from the registry.
• Laminated or altered certificates are refused for legalisation.
• You rarely need a notary for a birth certificate: DFAT can legalise the original registry certificate directly.

What is the difference between a full certificate and an extract?

A full birth certificate is the certified certificate a registry of births, deaths and marriages issues from its register. It typically shows your name, date and place of birth, sex, your parents' names and details, and registration information, and it carries the registrar's signature or seal and security features. The Australian Passport Office asks people born in Australia for their "full, original Australian birth certificate", which is the same document.

An extract of birth entry, sometimes called a short or abridged certificate, is an older format. It confirms that a birth was registered and gives a smaller set of details, often without full information about the parents. Registries issued extracts in the past, and many people born several decades ago still have one in a drawer. The Victorian Law Reform Commission noted in its review of birth certificates that an extract used to be enough for some identification purposes, but no longer is in Victoria or any other Australian jurisdiction.

A commemorative certificate is a decorative certificate that registries offer, often when parents register a birth. It is meant as a keepsake. It is not the version Australian bodies accept as proof of identity, even though DFAT lists commemorative birth certificates among the documents it can legalise.

Which one do overseas authorities want?

Almost always the full certificate. Foreign authorities use a birth certificate to establish who you are and, very often, who your parents are. Citizenship by descent, registering a birth abroad, marrying overseas, applying for residence or a pension, and inheritance all turn on your parents' details. An extract that leaves those out does not answer the question the authority is asking.

Many foreign authorities say so directly, asking for a "full", "long-form", "unabridged" or "integral" birth certificate. Italian consulates handling citizenship by descent, for example, commonly ask for full certificates; our guide to Italian citizenship by descent from Australia covers that process. Ireland's Foreign Births Register also works from full civil birth certificates; see our guide to the Irish Foreign Births Register.

If the instructions just say "birth certificate", do not guess. Ask the receiving authority, or its embassy or consulate in Australia, whether an extract is acceptable. The safe choice, if there is any doubt, is a newly issued full certificate.

Can DFAT apostille an extract?

Yes. DFAT's page on documents it can legalise lists Australian birth certificates, "including commemorative certificates and extracts". So legalisation is not the barrier. The barrier is what the apostille means.

An apostille, the certificate DFAT issues for countries in the Hague Apostille Convention, confirms that the signature, stamp or seal on the document is genuine. For countries outside the Convention, DFAT issues an authentication certificate instead, and the document then goes to that country's embassy or consulate for legalisation. Neither says anything about the document's contents, and neither changes what kind of document it is. An apostilled extract is still an extract. If the receiving authority wanted a full certificate, it will refuse the apostilled extract, and you will have paid for an apostille on the wrong document. Check whether a country is a Convention member on the HCCH status table on the day, because membership changes.

This mismatch, a correctly legalised document of the wrong type, is common. Our guide to having the wrong certificate type explains how to recover if it happens.

Should you order a new certificate?

Usually, yes, for three reasons. First, if what you hold is an extract, the registry can issue a full certificate from the same register entry, so you replace a doubtful document with the version authorities expect. Second, some foreign authorities want a certificate issued recently. The period, if any, is set by the receiving authority, and our guide to documents that are too old explains how that works. Third, the apostille or authentication certificate is attached to the original you lodge, which marks it. Many people prefer to keep their existing full certificate at home for Australian use and send a fresh one overseas.

Order the certificate from the registry in the state or territory where the birth was registered, not the state where you live now. Each registry sets its own identity requirements and application process, so check its website before you apply. Some registries also sell uncertified images or transcriptions of historical entries for family history research. Those are research copies, not certificates, and are not a substitute for a certified certificate.

What if the details on your certificate are wrong or have changed?

Overseas authorities compare your birth certificate against your passport and other documents, and small differences cause refusals: a misspelt given name, a parent's name recorded differently, a missing middle name. If the registry recorded something incorrectly, the fix is a correction through that registry, which then issues a corrected certificate. A notary cannot correct a registry record, and DFAT will not legalise a certificate you have altered yourself.

Some certificates are legitimately re-issued, for example after an adoption, a registered change of name, or a change to the recorded sex. A re-issued full certificate is still a full certificate. But an overseas authority may have its own view on which version it wants, particularly for citizenship by descent, where the question is who your birth parents were. Ask it before you order, and ask the registry what it is able to issue in your situation. Where a difference cannot be corrected at the registry, a declaration explaining it, sworn before a notary, is sometimes accepted overseas; our guide to a name mismatch between documents explains that route.

What if you were born overseas?

Then none of this is DFAT's to legalise. A foreign birth certificate is legalised in the country that issued it, by that country's apostille authority or its foreign ministry, and an Australian notary cannot vouch for a foreign registry's document. If you need a full certificate from overseas, order it from the civil registry of your country of birth, or through its embassy or consulate in Australia, and ask them about legalisation at the same time. If you became an Australian citizen, your citizenship certificate is a separate Australian document that DFAT can legalise.

Do you need a notary?

Usually not. An original Australian birth certificate issued by a registry is an Australian public document, and DFAT can legalise it directly, without a notary. Confirm the current process with DFAT before you lodge.

A notary becomes relevant in a few cases: when the receiving authority specifically wants a notarised copy rather than the original; when you want to keep the original unmarked and send a notarised copy for legalisation instead; or when you need a declaration about your birth details, for example explaining a discrepancy in spelling between your birth certificate and passport, sworn before a notary for use overseas. A copy certified by a Justice of the Peace cannot be apostilled. Our guide to apostilling a birth certificate covers the DFAT steps in more detail.

How do you get the right certificate ready?

1. Ask the receiving authority. Confirm it wants a full certificate, whether it needs to be recently issued, and whether it wants an apostille or authentication.
2. Look at what you already hold. If it is an extract, a commemorative certificate, or laminated, plan to replace it.
3. Order a full certificate. Apply to the registry in the state or territory where the birth was registered.
4. Check it on arrival. Make sure the names, dates and parents' details match your other documents, and raise any error with the registry before going further.
5. Have it legalised if asked. Lodge the original with DFAT for an apostille or authentication certificate.
6. Arrange a translation if needed. The receiving authority decides whose translation it accepts; ask before you order one.

Common mistakes to avoid

The most common mistake is sending the extract that has been in the family folder for decades, because it says "birth" on it and looks official. The second is getting that extract apostilled, then finding the authority wanted a full certificate. The third is sending a laminated certificate, which DFAT will not legalise. The fourth is sending the commemorative certificate from the day you were born, which is a keepsake rather than the document authorities expect. The fifth is ordering from the registry of the state you live in rather than the state where you were born.

Here is an illustration, not a real case.

Marco, born in Adelaide in the 1970s, is applying for citizenship through his Italian grandfather. His mother gives him the birth extract she kept, and he is about to send it to DFAT for an apostille. He checks the consulate's list first, sees it asks for full birth certificates, and orders a new full certificate from the South Australian registry. That is the one he has apostilled, and the extract stays at home.

In short

For overseas use, order a full birth certificate from the registry where the birth was registered. An extract of birth entry is an older, shorter format that is no longer accepted for identification in Australia and often not accepted overseas. DFAT can apostille an extract, but that does not make it a full certificate. Ask the receiving authority what it wants before you order anything. Our apostille and authentication services page explains how legalisation fits in.
