Australian Family Law: Divorce, Parenting and Property Guide

Family law in Australia is federal. A single statute, the Family Law Act 1975 (Cth), and one national court, the Federal Circuit and Family Court of Australia, govern divorce, parenting arrangements, property division, maintenance and child support for married and de facto couples alike.

This hub covers family relationship breakdown in Australia under the federal Family Law Act 1975 (Cth), for both married and de facto couples nationwide. It does not cover state and territory family violence protection order schemes, child protection (welfare) law administered by state agencies, or adoption law, all of which sit outside the Family Law Act. See the linked articles below for detail on each topic.

Family law is federal, not state-based

Family law in Australia is a matter for the Commonwealth Parliament, not the states and territories. The Family Law Act 1975 (Cth) applies nationwide, and the Federal Circuit and Family Court of Australia (FCFCOA) is the primary court hearing divorce, parenting, property and maintenance matters across every state and territory except Western Australia. Western Australia maintains its own Family Court of Western Australia, which applies the federal Family Law Act to married couples, but de facto property and maintenance claims there run under the Family Court Act 1997 (WA) because Western Australia never referred those matters to the Commonwealth. There is no separate "Queensland family law" or "Victorian family law." A parenting order, divorce or property order made in one state or territory is recognised and enforceable nationwide. This is why this cluster does not publish state-by-state variants: the substantive law is the same wherever a family lives in Australia.

The Family Law Amendment Act 2023: the parental responsibility presumption is gone

The Family Law Amendment Act 2023 repealed section 61DA of the Family Law Act 1975 outright, effective 6 May 2024. Section 61DA had created a presumption that equal shared parental responsibility was in a child's best interests. That presumption no longer exists in any form, and Parliament did not enact an automatic replacement. This is a repeal, not a reword: the table of provisions now jumps directly from section 61D to the new section 61DAA. Crucially, section 61C is unchanged and never depended on the presumption: each parent of a child under 18 automatically has parental responsibility, subject to any court order. New section 61CA encourages, but does not require, parents to consult each other on major long-term issues. New section 61DAA means joint decision-making on major long-term issues now applies only where a parenting order specifically says so. There is no default position either way; the outcome depends on what a court orders, or what the parents agree, in each case. See parenting orders in Australia for the full section 60CC framework that now governs every parenting decision. The same standing and best-interests rules apply when a grandparent applies: see grandparents' rights in Australia for the grandparent-specific standing under section 65C, kinship-care payments and what changed in the 2024 rewrite.

The Family Law Amendment Act 2024: family violence and companion animals

The Family Law Amendment Act 2024 commenced 10 June 2025, a date confirmed by the Attorney-General's Department and the FCFCOA rather than one read directly from the amending instrument's own commencement clause. It amended section 79, the core property-settlement provision, to require a court to consider the effect of family violence, including economic and financial abuse, on a party's contributions (section 79(4)(ca)) and on that party's current and future circumstances (section 79(5)(a)). It also inserted a dedicated companion-animal regime at section 79(6) and (7): a court may order sole ownership, transfer to a consenting person, or sale of a family pet, weighing factors such as who acquired and cared for the animal, any history of cruelty, and each party's attachment and future capacity to care for it. A court cannot order shared care of a companion animal. The Act also moved the financial disclosure duty into the Act itself at Division 1A, alongside the existing section 71B duty for married couples and new section 90RI for de facto matters. See property settlement in Australia for detail.

Parenting arrangements after separation

Parenting orders deal with who a child lives with, spends time with, and who holds and exercises parental responsibility for major long-term decisions such as health, education, religion and name. Section 60CA makes a child's best interests the paramount consideration, assessed against the section 60CC factors: safety, the child's views, developmental and cultural needs, each proposed carer's capacity, the benefit of relationships where safe, and, for Aboriginal or Torres Strait Islander children, the additional cultural considerations in section 60CC(3). Parents can agree their own parenting plan or apply to the FCFCOA for orders. See parenting orders in Australia for the full framework, and the family court process for how a parenting application actually proceeds.

Four further guides cover the situations that most often bring parents back before the court: relocating with a child interstate or overseas, including recovery orders, the AFP Family Law Watchlist and passport consent; family violence in a parenting case, from the section 60CC(2A) safety factor to cross-examination protections and how a state family violence order interacts with a federal order; contravention of a parenting order under Division 13A, with the reasonable-excuse defence and the ladder of consequences; and a child's views and the Independent Children's Lawyer, including the 2024 duty on the ICL to meet the child.

Divorce: ending the marriage itself

Divorce is a separate legal step from resolving parenting, property or maintenance. Section 48 requires 12 months' continuous separation before an application can be filed, and section 49(2) allows separation to be established even where the couple continued living under one roof. From 1 July 2026 the FCFCOA's application for divorce fee is $1,170 (reduced fee $390 for eligible concession holders). A divorce order takes effect one month after it is made under section 55, described by the court as finalised "one month and one day later." Divorce does not itself resolve who gets what property or how children's arrangements will work; those need separate applications. See divorce in Australia for the complete process, fees and eligibility rules.

Property settlement, agreements and maintenance

Property division under the Family Law Act is not an automatic 50/50 split. Section 79 (married couples) and section 90SM (de facto couples) direct a court to identify the property pool, weigh each party's financial and non-financial contributions, weigh current and future circumstances, and make only the order that is just and equitable in that family's circumstances. Since 10 June 2025, section 79(4)(ca) and 79(5)(a) require courts to weigh the economic effect of family violence, and section 79(6)-(7) gives courts specific, limited powers over companion animals. Couples can instead formalise their own division through a binding financial agreement under sections 90B, 90C or 90D (married) or 90UB to 90UD (de facto), provided each party receives independent legal advice under section 90G. A party who cannot adequately support themselves may also seek spousal maintenance under section 72(1), assessed against the section 75(2) factors.

See property settlement, binding financial agreements and spousal maintenance in Australia for the detail on each.

De facto relationships

De facto couples have access to largely the same financial remedies as married couples under Part VIIIAB of the Act. Section 4AA defines a de facto relationship by reference to a list of non-exhaustive factors, including duration, common residence, financial interdependence and public reputation as a couple; no single factor is decisive. To apply for a property or maintenance order, a couple generally must satisfy the threshold in section 90SB: at least two years together, a child of the relationship, substantial contributions with serious injustice otherwise, or state or territory relationship registration. The limitation periods differ sharply from marriage; see de facto relationships in Australia for the two-year-from-separation rule and how it compares to divorce.

Child support

Child support is assessed administratively, not by a family law court. Services Australia applies an eight-step formula under the Child Support (Assessment) Act 1989, combining both parents' incomes above a self-support amount, each parent's percentage of care, and the Costs of the Children Table. For the 2026 Child Support Period the self-support amount is $31,046, the minimum annual rate is $551, and the fixed annual rate is $1,825 per child; these figures index on 1 January, not 1 July. See child support in Australia for the full formula and the child support calculator explainer for a worked, estimate-only example.

Getting help: the family court process

Most separating couples never see a courtroom; they negotiate directly, use family dispute resolution, or reach a private agreement. Where court involvement is needed, the FCFCOA is a single national court applying a unified set of rules, pre-action procedures and, for child-related matters, the evidence principles now found in section 102NL, the successor to the repealed section 69ZT. See the family court process in Australia for how an application actually moves through the system, from pre-action requirements to a final hearing.
