"Adoption papers" is not one document. It is a family of three or four, issued by different bodies, and each one reaches an apostille by a different route. One of them may not need a notary at all, and another may not need an apostille at all. Working out which document the foreign authority actually wants, and which route it takes, is most of the job.
This page is about that routing. For the notary appointment itself, access to records and privacy, see How to Notarise an Adoption Paper in Australia.
The adoption order. The order that made the adoption. Adoption in Australia is governed by state and territory law, and orders are made by the court or authority each jurisdiction designates.
The post-adoption birth certificate. Once an adoption is registered, the state or territory Registry of Births, Deaths and Marriages issues a birth certificate showing the adoptive parents.
The original birth certificate. The pre-adoption record, released under state adoption information law, sometimes with notations or conditions.
An adoption compliance certificate. For an intercountry adoption made under the Hague Adoption Convention, a certificate confirming the adoption was made in accordance with that Convention.
This is a registry certificate, which makes it a public document signed by a government official. DFAT can generally apostille an original BDM certificate directly, with no notary involved. Confirm with DFAT for your particular certificate before lodging, especially if it is an older issue.
For passports, school enrolment and many citizenship applications, this certificate is all the foreign authority needs. It is also the least sensitive of the adoption documents, because it does not describe the birth family or the circumstances of the adoption. Before sending anything else overseas, ask the receiving authority in writing whether this certificate alone is sufficient.
Whether DFAT can apostille a court-issued copy of an order directly depends on whether it holds a specimen for the court officer who signed or sealed it. That varies, and it is the question to put to DFAT before you lodge.
Where DFAT cannot verify the court's signature, a notary certifies a true copy of the sealed order and DFAT apostilles the notary's certificate instead. The apostille then speaks to the notary, not the court. Most receiving authorities accept this; some want the court's own seal authenticated. If the instructions are unclear, ask.
Either way, you need a sealed copy issued by the court or the adoption authority. A photocopy from a family file, or a copy certified by a Justice of the Peace, cannot be apostilled. A JP's certification carries no signature DFAT can verify.
In principle, a pre-adoption certificate lawfully released by the registry is a registry certificate like any other. In practice, certificates released under adoption information provisions can carry notations or conditions of release, and a foreign authority may treat them differently from a standard certificate. Confirm with both DFAT and the receiving authority before relying on one.
The Hague Adoption Convention (1993) and the Hague Apostille Convention (1961) are different treaties. The compliance certificate exists under the first. Its purpose is to have an intercountry adoption recognised in other states party to that Convention without further formality.
So before paying for an apostille on a compliance certificate, ask the receiving authority whether it needs one. If the destination is party to the Adoption Convention, it may not. If it wants one anyway, confirm with DFAT how the certificate should be lodged.
A country can be party to one Convention and not the other. Check each against the relevant HCCH status table on the day you act — membership changes, and "it's a Hague country" means nothing until you know which Convention is meant.
Every route above then ends differently: DFAT authenticates the document, and the destination's embassy or consulate in Australia legalises it. Embassies set their own rules, and some ask for adoption documents to be accompanied by a translation before they will legalise them. Ask the embassy for its requirements before lodging with DFAT.
Adoption documents are harder to translate than most. Terms such as "adoption order", "relinquishing parent" or "discharge of order" may have no exact equivalent, and a translator should render them faithfully with a note rather than substitute a foreign legal concept that means something different. Use a NAATI-certified translator, and confirm with the receiving authority whether the translation is done before or after the apostille — some destinations require it to be authenticated with the document, others require it to be done locally.
Birth certificates are often subject to issue-date limits abroad; adoption orders usually are not, since an order does not change. If the receiving authority does set a limit on the birth certificate, order a fresh one from the registry and apostille that, rather than the copy issued at the time of the adoption.
Does an apostille make my adoption recognised overseas? No. An apostille confirms a signature and seal. Recognition is a question of the destination's law and, for intercountry adoptions, the Hague Adoption Convention.
My adoption took place overseas. Can DFAT apostille the foreign order? No. DFAT authenticates Australian documents only. The foreign order must be authenticated in the country that made it.
Do I need a notary at all? For the post-adoption birth certificate, possibly not. For a court order DFAT cannot verify, yes.
