Citizenship documents get notarised when someone has to prove nationality to a government that is not their own — claiming a second citizenship by descent, renouncing one in order to acquire another, proving status for an overseas property purchase or inheritance, registering a birth with a foreign consulate, or satisfying an employer's right-to-work check.
The receiving body is almost always another country's government department, which means the standard is higher and the tolerance for irregularity lower.
"Citizenship document" covers several things in Australia, and they are not interchangeable:
Ask the receiving authority which of these they want, in writing. A notarised copy of the wrong one is a wasted fee and a wasted week.
An Australian notary public sights the original and certifies that the attached copy is a complete and accurate copy of the document sighted. They can also witness your signature on an application, a declaration or a renunciation form, and administer an oath or affirmation where a sworn statement about your status is required.
A notary cannot certify that you are a citizen, that the certificate is genuine, or that you have not since lost or renounced the status. Only the issuing government can. A foreign authority will usually verify the document with that department independently — the notarial certificate gets it accepted into the process, it does not replace verification.
A notary also cannot issue an apostille. Only the Department of Foreign Affairs and Trade does that.
This is the constraint that distinguishes citizenship documents from most others on this site, and it is worth a phone call before an appointment.
Some identity and status documents carry restrictions or official warnings about reproduction, and the rules differ depending on the issuing country and the era the document was issued. Where a restriction applies, the usual answer is not to copy the document at all but to obtain an officially issued extract, a replacement, or a confirmation letter from the issuing department, and to have that certified instead.
So: if a document carries wording about not being copied, raise it at the booking. A notary told this up front can advise on the alternative; one who discovers it mid-appointment will stop. And do not assume a passport photo page can be certified for every purpose — it usually can, but where the receiving body is a foreign government, check what form they will accept.
This page deliberately does not list which documents carry such restrictions, because that is exactly the detail that changes. Ask the issuing department.
The two most common reasons people are here, and the two with the most avoidable failures.
Claiming citizenship by descent in another country. The foreign consulate typically wants an unbroken documentary chain: your birth certificate, your parent's, sometimes your grandparent's, marriage certificates for every name change along the way, and the ancestor's naturalisation record. Each may need certifying and apostilling, so the cost is driven by the number of documents. Establish the complete list before you certify anything — people routinely pay for a document the consulate never wanted.
Renouncing a citizenship. Some countries require proof that you have renounced another nationality before they will naturalise you; others require proof you hold one before accepting a renunciation. The order of operations is set by the two governments involved and can be circular. Get the sequence confirmed in writing by both before signing anything irreversible — renunciation is usually permanent, and a notary witnessing that signature will want to be satisfied you understand it.
Fifteen to twenty minutes for a certified copy; longer if you are also signing.
If you are signing a renunciation or an application, bring it unsigned. A notary witnesses a signature by watching it being made.
Transliteration deserves its own line. Names moving between scripts are a leading cause of rejection in nationality matters, because the spelling on a birth certificate, a passport and a foreign register may all differ legitimately. Deal with it by sworn declaration rather than hoping the clerk at the far end is relaxed about it.
The notarial certificate is an Australian act. Before a foreign government accepts it, the notary's signature and seal generally need authenticating.
If the destination is a member of the Hague Apostille Convention, DFAT issues an apostille and that is sufficient across all member states. If it is not a member, the document goes to DFAT for authentication and then to that country's embassy or consulate in Australia for legalisation, with that embassy's own requirements.
Note that consulates dealing with nationality matters often have longer queues and more exacting document standards than the same consulate's visa section, and some require appointments booked well ahead. Factor that in.
Notarial fees are not fixed by statute in Australia and vary by state and practitioner. As a market estimate, a certified copy commonly falls in the $80–$150 range with additional documents or copies at the same appointment charged at a lower rate. Descent claims involve document chains rather than single items, so ask for a quote against the consulate's full list. DFAT charges per document, which is the cost that surprises people — ten documents means ten apostilles.
Can a Justice of the Peace certify my citizenship certificate? Inside Australia, yes, and it costs nothing. For a foreign government, no. A JP's certification is not recognised internationally and DFAT will not authenticate it, so it cannot be apostilled.
Can my passport be used instead of a citizenship certificate? Frequently, yes — a certified copy of the photo page is widely accepted as evidence of nationality. Whether it satisfies a particular authority is their decision, so ask before ordering a replacement certificate you may not need.
I have lost my citizenship certificate. Apply to the Department of Home Affairs for evidence of citizenship or a replacement. A notary can only certify a copy of a document that exists and that you can present.
How long is a certified copy accepted? The act does not expire, but nationality authorities commonly refuse documents more than three or six months old. Time the certification to the lodgement rather than preparing it early.
