De Facto Separation Rights in Australia: Your 2026 Guide to Property, Super and the 2-Year Deadline

Under section 4AA of the Family Law Act 1975, a de facto relationship exists where two people, who may be of the same or different sex, have a relationship as a couple living together on a genuine domestic basis, and are not married to each other or related by family. Importantly, a de facto relationship can exist even if one person is legally married to someone else, or is in another de facto relationship at the same time.

There is no single test. The court weighs a range of circumstances and decides how much weight each deserves in your particular situation. No one factor is essential, and the absence of any single factor does not rule a relationship in or out.

The circumstances a court may consider include:

• The duration of the relationship and the nature and extent of living together
• Whether a sexual relationship exists
• The degree of financial dependence or interdependence, and any arrangements for financial support
• The ownership, use and acquisition of property
• The degree of mutual commitment to a shared life
• Whether the relationship is or was registered under a state or territory law
• The care and support of children
• The reputation and public aspects of the relationship

This matters because the rights described in this guide only become available once a relationship is accepted as de facto. Living together, sharing bills, or even having a child together does not automatically make every couple de facto, and equally, you can be in a de facto relationship without ever having lived together full-time.

For financial matters (dividing property and superannuation, or seeking maintenance), the court can only make orders if your relationship clears one of four gateways. At least one of the following must be true.

• The de facto relationship lasted for at least 2 years in total
• There is a child of the de facto relationship
• The relationship was registered under a prescribed state or territory relationship register
• One party made substantial contributions (financial, non-financial, or as a homemaker or parent) and serious injustice would result if no order were made

If none of these applies, the court generally has no power to alter property interests, no matter how unfair the outcome feels. This is the single biggest difference from marriage, where the right to a property settlement is automatic.

Registering your relationship (available in NSW, Victoria, Queensland, the ACT, Tasmania and South Australia, but not WA or the Northern Territory) is significant because it provides conclusive proof the relationship existed, removing the need to argue about whether you were truly de facto.

This is the most important date in this guide. Under section 44(5) of the Family Law Act, you must apply to the court for a property settlement or spousal maintenance within 2 years of the date your de facto relationship ended. Miss it, and you lose your automatic right to apply.

After 2 years, you can only proceed with the court's permission (called leave). The court must be satisfied under section 44(6) that hardship would be caused to you or a child if it refused. Leave is discretionary and is not always granted, so you should never assume you will get a second chance.

Because there is no divorce and no register of separation for de facto couples, the date of separation is simply a factual question. Separation can happen even while you are still living under the same roof. If the date is disputed, you may need contemporaneous evidence, such as messages, emails, changed living arrangements or financial records, to establish when the relationship actually ended.

If your 2 years is close to running out and you have not reached an agreement, the safest step is to file an application (or get advice immediately) to preserve your position, even if you intend to keep negotiating.

For de facto couples outside WA, property is divided under the same provisions and the same approach the courts use for married couples. There is no automatic 50/50 split. The court works toward an outcome that is just and equitable in your specific circumstances.

In practice, family lawyers describe the process in four broad stages. First, identify and value the entire asset pool, including the home, savings, debts, businesses and superannuation. Second, assess each person's contributions, both financial (income, an inheritance, a deposit) and non-financial (renovations, homemaking, and parenting). Third, consider future needs, taking into account factors such as age, health, income, earning capacity and who cares for the children. Fourth, check that the overall result is just and equitable.

Superannuation counts as property and can be split between you. In Western Australia, super splitting for de facto couples only became available for cases filed on or after 28 September 2022; settlements finalised before then could not split super.

From 10 June 2025, reforms to the Act apply to all separating couples, including de facto couples, and whether you settle in court or by agreement. The court now follows a clearer codified framework, can make orders about companion animals (pets), and must consider the economic effect of family violence. Family violence, including financial abuse, is now relevant at two stages: when assessing past contributions, and when assessing future needs.

From 10 June 2025, courts must consider the economic effect of any family violence when deciding a property settlement, where it is relevant. This codifies a long line of cases recognising that abuse can make it harder for a victim to contribute, and can leave lasting financial damage.

Family violence is considered at two points. When assessing contributions, the court looks at how violence affected a party's ability to contribute, financially or as a homemaker and parent. When assessing future needs, it looks at the ongoing economic impact, which can include damaged credit, interrupted careers and debts run up in a victim's name.

The Act also now contains a stand-alone definition of economic or financial abuse as a form of family violence (section 4AB). Examples include unreasonably controlling someone's access to money, coercing them into debt, and dowry abuse.

If family violence is part of your situation, it is worth raising it with a lawyer early, because it can directly affect the share of property you receive. Free support is available through 1800RESPECT (1800 737 732).

A former de facto partner can, in some cases, be required to financially support the other after separation. Under section 90SF of the Family Law Act, this only applies where one person is unable to support themselves adequately, for example because they are caring for a child of the relationship under 18, or because of their age, or a physical or mental incapacity for suitable work.

There is a second limb: the other person must be reasonably able to pay. The court looks at what is reasonable and adequate by reference to factors in sections 75(2) and 90SF(3), including each person's income, property, financial resources, age, health and earning capacity.

Spousal maintenance is separate from child support. Child support for the day-to-day costs of children is handled by Services Australia, not the family courts, and is calculated under a separate formula.

The same 2-year deadline applies: in most cases you must apply for spousal maintenance within 2 years of separation.

WA never fully referred its family law powers to the Commonwealth for de facto couples, so de facto property and maintenance matters there are governed by the Family Court Act 1997 (WA) and heard by the Family Court of Western Australia, not the Federal Circuit and Family Court of Australia.

The substantive approach is broadly similar (a just and equitable division based on contributions and future needs), and since 28 September 2022 super can be split for WA de facto couples. But the jurisdiction has its own geographical connection rules.

To bring a WA de facto property claim, generally at least one party must be living in WA on the day the application is filed, and either both parties lived in WA for at least one third of the relationship, or substantial contributions were made while a party lived in WA.

Elsewhere in Australia, similar geographical connection rules apply through the participating jurisdictions, broadly requiring that the parties were ordinarily resident in a participating state or territory at relevant times. The 2-year deadline applies in WA too.

Reaching an agreement with your former partner is only half the job. A private, informal handshake agreement is not legally binding and can be reopened later. To make a property division final and enforceable, you generally use one of two paths.

Consent orders are an agreement filed with and approved by the court, which then has the force of a court order. As an indicative figure, the filing fee for an application for consent orders was $205 from 1 July 2025. A binding financial agreement (sometimes called a separation agreement) is a private contract, but for it to be binding each party must have received independent legal advice.

Court fees are indexed and change, typically on 1 July each year, so confirm the current amount at the official source before you file. As an indicative comparison, a divorce application (which only applies to married couples, not de facto couples) was $1,125 from 1 July 2025.

Before going to court, you are generally expected to make a genuine effort to resolve matters, including through family dispute resolution where appropriate. If you are unsure whether your situation clears a gateway, whether your 2 years has expired, or how WA's rules affect you, get advice from an accredited family law specialist early, as the deadlines are unforgiving.
