De facto separation: the two-year time limit for property claims

Separating couples who lived together unmarried often assume family law does not really apply to them. It does, including one rule that bites harder than any other: under section 44 of the Family Law Act 1975¹ (Cth), a de facto partner generally has just two years from the end of the relationship to start court proceedings for property settlement or spousal maintenance. Miss it and your claim may be gone².

Why the deadline matters more than people think

The two-year clock runs from separation, not from divorce³ (there is no divorce), not from selling the house, and not from the day talks break down. Many people spend exactly those two years negotiating politely, assuming the option to litigate waits patiently behind the scenes. It does not. Once the period expires, filing requires the court’s permission on grounds that are difficult to establish.

Practical consequences follow even earlier: valuations age, bank records vanish, superannuation details go stale, and the other side gains every advantage of delay.

Superannuation deserves special mention. Splitting interests requires formal orders or agreements, and gathering fund information takes weeks on its own. Starting the process inside year one, rather than month twenty-three, converts a deadline scramble into routine administration.

The two-year rule in detail

Section 44(5) requires de facto property and maintenance proceedings to be instituted within two years after the relationship ended. Key features:

• The trigger date is the end of the relationship, which is not always obvious where couples drifted apart while cohabiting in stages.
• Financial agreements or consent orders made during that window can bring finality sooner.
• The deadline applies to instituting proceedings; informal negotiations do not pause it.

Married couples play by a different timetable, generally 12 months from divorce becoming final, so blended advice borrowed from married friends is often simply wrong for de facto situations.

Separation dates get contested surprisingly often, particularly where couples separated under one roof or drifted apart gradually. Evidence such as changed sleeping arrangements, separate finances, agency notifications and messages to friends fixes dates, and fixing them early prevents the limitation question from swallowing the entire case.

Getting more time: the hardship extension

Courts can grant leave to apply out of time, but only in defined situations. The classic ground is hardship: the applicant would lose the prospect of a serious money claim if refused. Courts have treated hardship generously enough to include substantial contributions, such as years of unpaid work renovating properties or building a business, that produced no corresponding title or savings.

Still, the application is discretionary and evidence-driven. Waiting out the deadline hoping a sympathetic judge later appears is litigation roulette, and the cost of a leave application alone often exceeds early settlement concessions. Leave applications also consume money that could have funded settlement instead, a circular waste that early filing avoids entirely.

Does the Act even apply to your relationship?

Before the deadline debate comes the threshold question. The Family Law Act covers de facto relationships meeting certain criteria, broadly:

• A genuine domestic relationship living together on a true domestic basis.
• Duration of at least two years, or alternatively a child of the relationship, or contributions of a major kind warranting adjustment, or registration of the relationship.
• Sufficient Australian geographic connection for the case to proceed here.

Contested threshold issues arise constantly: couples with two households, relationships ending in stages, arrangements where one party insists nothing legal ever existed. If the other side denies jurisdiction, expect that fight to consume year one unless resolved fast.

Registration of relationships, available in Queensland, removes duration arguments entirely, though few couples register. Where thresholds look shaky, evidence of shared finances, public presentation as partners and joint purchases builds the jurisdictional case piece by piece.

Beating the clock in practice

Sensible sequencing inside the window:

1. Confirm early that the relationship meets the Act’s thresholds.
2. Exchange full financial disclosure, covering assets, liabilities, superannuation and interests in trusts or companies.
3. Attempt negotiated resolution or mediation with deadlines attached, not open-ended drift.
4. If agreement lands, formalise it properly through consent orders or a binding financial agreement so it is actually enforceable.
5. If talks stall near the mark, file protective proceedings before expiry and negotiate from inside the courtroom if necessary.
6. Check superannuation balances formally through fund requests rather than guessing from old statements.

Filing protectively is not aggressive; it preserves rights while negotiation continues.

What happens after the window closes

Options narrow sharply once the two years lapse. Negotiated settlements remain lawful, since nothing stops former partners agreeing privately at any age of a dispute, but leverage shifts entirely to whoever holds the assets. Leave applications demand hardship evidence that grows harder with time, and partial performance arguments complicate rather than simplify. Practically, missing the deadline converts a legal claim into a moral conversation, which is a poor position from which to divide a decade of contributions.

Related deadlines worth knowing

Superannuation splitting, stamp duty concessions on transfers between former partners, and spousal maintenance each carry their own procedural requirements, some tied to the same two-year window. Duty concessions have eligibility rules worth verifying rather than assuming, and bundling everything into one coordinated resolution beats discovering a lapsed entitlement two years later.
