Partner and child documents for Subclass 500 in 2026: marriage, birth and custody proof

For a Student visa (Subclass 500) application, the Department of Home Affairs breaks family evidence into separate blocks: your partner needs identity and character documents plus proof that the relationship itself is real and legally recognised, and each accompanying child needs a birth certificate or family book naming both parents, adoption papers where relevant, and — where the person with legal care is not a biological parent — proof of that guardianship. This reflects the "Gather your documents" section of the Australian Department of Home Affairs Student visa (Subclass 500) official page, as at the August 2026 version of that page. That same page points applicants to the Document Checklist Tool, which generates a list tailored to your country of passport and education provider; check it again immediately before you submit, because the Department updates it routinely twice a year, on 31 March and 30 September.

This article is general information about how the published requirements are framed, not personalised advice for your circumstances; amounts, categories and the current checklist always remain subject to what the Department has most recently published.

What documents does the Department ask for from a partner?

The official page lists three things for your partner: identity documents, character documents, and documents about other family members where applicable. This means adding a partner is not a matter of attaching one relationship certificate — the partner is assessed as a visa applicant in their own right, on identity and character, before the relationship test is even reached.

Family members must hold a valid passport in order to lodge the application. If the application is lodged in Australia and a current passport expires, the passport has to be renewed before lodging. Alongside the passport pages showing photo, personal details and issue and expiry dates, the page asks for a national identity card if you have one, and proof of any change of name.

The consequences of failing on identity are stated bluntly there: if identity cannot be proved, the application will be refused, the applicant might not be granted another visa for 10 years, and any family members listed on the same application might also not be granted a visa for 10 years. That makes the identity block, not the relationship block, the first thing worth auditing in a family application.

Married applicants: what counts as proof of the marriage?

If you are married, the listed requirement is your marriage certificate or other evidence that your marriage is valid in Australia. Two ideas sit inside that sentence, and they are worth separating.

First, the certificate itself. A marriage certificate is evidence of the event. Second, validity in Australia. A document that is perfectly valid where it was issued does not automatically answer the second question, so where the certificate alone does not establish recognition, the page leaves room for "other evidence that your marriage is valid in Australia" rather than treating the certificate as conclusive on its own.

A marriage certificate also has a second, easily overlooked role. It appears on the official list of documents that prove a change of name, alongside divorce certificates, change of name documents from an Australian Registry of Births, Deaths and Marriages or the relevant overseas authority, and documents showing other names you have been known by. If a partner's surname travelled onto the passport through marriage, mismatches across passports, bank documents and school records are exactly what delays assessment — and this is the gateway question for every other family document you attach.

De facto partners: what is required beyond relationship evidence?

For de facto partners, the page asks for documents that show you are in a de facto relationship, then adds a separate layer: additional proof of the relationship, being either evidence that you have been in the de facto relationship for at least 12 months before you applied for this visa, or — where applicable — evidence that the relationship is registered by a participating Australian state or territory.

Note the structure. The relationship documents come first; the 12-month history or the registration is described as additional proof. So a folder of joint documents without a timeline, or without a registration record where registration applies, does not match what is asked for.

What must you provide for each dependent child under 18?

For every dependent child under 18 applying with you, the official page requires copies of birth certificates or the family book showing the names of both parents of all your dependent children, plus copies of the adoption paper where applicable.

The operative words are both parents. A short-form extract, a hospital notification of birth or a document naming only one parent does not satisfy a requirement written as showing the names of both parents of the child. Where the family book is used, it carries the same burden: both parents must appear.

Who has legal guardianship, and how do you prove it?

Where somebody other than a child's biological parents has legal guardianship — adoptive parents or a court-appointed guardian, to use the page's own examples — the page requires proof of that legal guardianship, and states this can be adoption papers or parental court orders, where applicable.

The custody question therefore has two distinct document families. Adoption is proved by the adoption papers. Guardianship established by a court is proved by parental court orders. A statement signed by a parent, or a letter permitting the child to travel, is not one of the listed documents — it answers different questions, which are covered next.

Does a travelling parent need consent from the other parent?

For dependent children, the consent issue most often surfaces through welfare rather than through the birth certificate itself. Where the Subclass 500 applicant is under 18, the page requires appropriate welfare arrangements covering the period of stay or until the applicant turns 18, whichever comes first, and consent from the parent or guardian to travel to and reside in Australia as an under 18 student. Where a guardian is applying for a Subclass 590 Student Guardian visa, both applications should be made at the same time.

For a child travelling with one parent while the other remains overseas, the birth certificate establishes who the parents are, but the published consent requirement applies to applicants who are themselves under 18, and no separate consent document is itemised for a dependent child travelling with one parent; because nothing covering that situation appears in the published requirements, the document checklist generated for the child's passport country should be re-checked immediately before lodgement.

Which children qualify as dependants, and when does a child need their own visa?

Only unmarried children under the age of 18 can be included as a dependant. If you have a child who is 18 or over, or a child who will turn 18 before the Student visa is granted, they need to apply for their own visa. Two notes on the page reinforce this: a visa cannot be granted to a child who is 18 or over at the time the application is finalised, and where subsequent entrants are siblings — two or more children with no parent — each must make a separate application and each pay the base visa application charge to join the parent.

Age interacts with status and timing, not just with the application date. A child who is 17 when the family lodges but turns 18 before the decision is made falls out of the dependant definition, so this belongs on any pre-lodgement checklist for families with children close to 18.

Do family members joining later use the same list?

Family members can be included in your application or apply to join you later as a subsequent entrant, but only if you declared them when you lodged, or they became your family member after you were granted the visa. Existing family members must have been declared at lodgement; someone who became a family member after lodgement but before grant required written notification to the Department before the visa was granted. Declaring all family members even where they do not plan to travel is required, because undeclared family members are not eligible for a Student visa to join you later.

Subsequent entrants sit outside part of the normal flow. The page states that all subsequent entrants must attach evidence of financial capacity with their application, that the document checklist is not relevant for them, and that evidence may be refused without a request for more information if it is missing.

Family members must also meet health and character requirements and be a genuine student dependent.

What triggers requests for further information in family cases?

Three mechanics on the page explain most delays.

The first is lodgement completeness. The Department may finalise an application based on the information provided when it was first lodged, so anything attached after the decision cannot help; there is also a maximum of 60 documents per application, which constrains how much family material can be loaded. The second is accuracy: the page points to what happens if you cannot prove identity or do not provide true information, and separate requirements arise later if your situation changes — relationship status, welfare arrangements and the birth of a child all have to be notified. The third is the checklist's own revision cycle; because the tool is reissued twice yearly, a list printed months earlier may no longer match what is expected on the day of submission.

Assume, for example, that an applicant lodges with a birth certificate issued in a short form that names only the mother. Nothing else in the file establishes who the second parent is. This is a plausible reading of the stated requirement rather than a documented case, but the mismatch with a requirement written as "showing the names of both parents" is self-evident, and the request for further information follows from the document, not from anything about the family.

What else do accompanying family members add to the application?

Adding family members changes the financial and health-cover picture as well as the document list. For evidence of financial capacity, living costs for 12 months are given as AUD29,710 for students, AUD10,394 for partners coming with you and AUD4,449 for a child coming with you, with schooling costs of at least AUD13,502 per year for each accompanying school-age child. Alternatively, evidence that parents or the partner had personal annual income of at least AUD87,856 in the 12 months before applying — or at least AUD102,500 where family members are included — may be given, in the form of official government documents such as tax assessments less than 12 months old; bank statements and direct evidence from an employer are not accepted for this purpose. Further detail sits in the Migration (LIN 19/198: Evidence of financial capacity—Subclass 500 Visa and Subclass 590 Visa) Instrument 2019.

Health cover is separate and unforgiving: Overseas Student Health Cover must cover everyone included in the application, and the page states the visa will be refused if OSHC is not provided in the application form. The provision here is general information about published requirements and not an assessment of any individual application; where the published figures and later official updates differ, the later official publication governs.

Frequently Asked Questions

Do I need a marriage certificate if my partner is not applying for the visa?

The partner document list applies to a partner who is included in the application. If no partner is applying, no partner identity, character or relationship evidence is required. Note that family members still have to be declared even where they are not travelling, because undeclared family members cannot later join you on this basis.

Can a de facto partner qualify without 12 months of cohabitation?

The page states the 12-month requirement as one of two options. The alternative is evidence that the relationship is registered by a participating Australian state or territory, where applicable. Relationship documents are required in either case, because the 12-month history or registration is described as additional proof on top of them.

What counts as proof of change of name?

A marriage or divorce certificate, change of name documents from an Australian Registry of Births, Deaths and Marriages or the relevant overseas authority, and documents showing other names you have been known by. This applies to the applicant's identity evidence as set out on the official page.

Does an adoption certificate replace a birth certificate?

No. The adoption paper is listed alongside the birth certificate or family book as an additional document, where applicable, rather than as a substitute for it. Keep both, since the two documents establish different facts.

My child turns 18 next month — can they still be included?

They can only be included if they are unmarried and have not turned 18. If a child will turn 18 before the Student visa is granted, they need to apply for their own visa, and a visa cannot be granted to a child who is 18 or over when the application is finalised.

Can my children join me after my visa is granted?

Yes, as subsequent entrants, provided they were declared in your application, or became your family member after your visa was granted. Subsequent entrants must attach evidence of financial capacity with their application, and the checklist does not apply to them for that requirement.

Do siblings travelling without a parent apply together?

No. Where subsequent entrants are siblings — two or more children with no parent — each must make a separate application and each pay the base visa application charge to join the parent.
