In New South Wales, you have two years from the day your de facto relationship ended to apply to the court for orders about property. That is the de facto property settlement time limit, and it comes from section 44(5) of the Family Law Act 1975. Once the two years are up, you cannot simply file. You need the court’s permission first, and permission is not a formality.

Two years reads as generous. In practice it rarely is.

A pattern worth naming: two people argue for months over whether a claim is worth ten per cent or half of everything, and nobody asks when the separation actually happened. If it was three years ago, that argument is beside the point until leave is dealt with.

Key takeaways

• Two years from separation to file. The de facto property settlement time limit sits in section 44(5) of the Family Law Act 1975.
• This is a different clock from the two years of living together that people talk about. That one is about eligibility.
• An informal agreement does not finalise a de facto property settlement, and it does not stop the clock running.
• Out of time, a de facto property settlement needs the court’s leave, and hardship has to be shown.
• Separation dates get argued about, particularly after a reconciliation or a long stretch living under one roof.

How long is the de facto property settlement time limit in NSW?

Two years from the breakdown of the relationship. Filing means starting proceedings in the Federal Circuit and Family Court of Australia, for most Sydney matters through the Sydney registry. An application for consent orders recording a de facto property settlement counts. So does a contested application. An email agreeing on who keeps the house does not, and neither does a signed spreadsheet.

The de facto property settlement NSW couples deal with is governed by federal law, not state law. NSW referred its powers to the Commonwealth in 2009, so there is no separate de facto relationship property settlement NSW regime, and de facto property settlement Australia-wide has run on one system since, with Western Australia joining last in 2022.

The de facto property settlement Family Law Act provisions sit in Part VIIIAB. Section 90SM gives the court power to alter property interests between former de facto partners. Section 44(5) closes the door on that power once the window shuts.

The two-year rule people talk about is a different two years

Most of what gets said online about “the two-year rule” has nothing to do with the deadline. It is about eligibility: whether a de facto property settlement can be sought at all. The belief is stated confidently, and agreed with by plenty of people, that two years of living together is what lets a partner make a claim, and that below two years you are in the clear.

That is one gateway, not the rule. Under section 90SB, the court can hear a de facto relationship property settlement where the relationship lasted at least two years in total, or where there is a child of the relationship, or where one person made substantial contributions and refusing orders would cause serious injustice, or where the relationship was registered under the Relationships Register Act 2010 (NSW). Any one of those is enough on its own.

Cohabitation is also less decisive than people assume. Section 4AA lists a range of indicators, and a common residence is only one. Couples who kept separate homes have been found to be de facto. Clients ask, is my de facto entitled to my property when we never properly moved in together, and the answer turns on how the rest of the relationship looked.

The other habit worth breaking is treating length as an outcome. People search “can de facto partner claim property” expecting a percentage tied to years. Duration is one factor among several in de facto relationship property division, sitting alongside contributions and future needs. A short de facto relationship property settlement can still produce a substantial adjustment where one partner funded the deposit or gave up work.

Three things are getting mashed together in these conversations: whether the relationship qualifies, what the claim is worth, and how long you have to bring it. Only the last has a hard edge, and the de facto property settlement time limit is the one nobody checks first.

When did your de facto relationship actually end?

The limitation date that de facto property settlement claims are measured against is the date of separation. That date is a fact to be proved, not a number you look up.

There is a piece of internet folklore that you can reset the de facto clock by separating for a day every couple of years. A separation has to be real. If one person never moved out and the household kept running as it always had, calling it a break does not make it one.

The same problem catches people at the other end. A reconciliation that lasted three months, or a partner who stayed in the spare room until the lease ran out. Each produces a real argument about when the two years started, and both sides usually have a version that suits them. Parties do sometimes negotiate an agreed commencement or end date as part of a de facto separation property settlement, which tells you how loose these dates can be.

If you are early in this, write down what you can while it is fresh: when you told family, when the joint account arrangement changed, when one of you stopped paying into the mortgage.

How do people miss the de facto property settlement time limit?

Usually because the process itself eats the window. Correspondence, disclosure, a mediation, then a second mediation. Negotiation alone running past eighteen months is not unusual, so opening an informal conversation at month twenty leaves nothing in reserve.

Cost is the other driver. Staying out of court and keeping fees down is a reasonable instinct, and contested property litigation is expensive. The cheapest version, two people working it out between themselves, is also the version with nothing on a court file.

Then there is the amicable separation, which is the one that most often drifts past the time limit for de facto property settlement. The agreement gets made in the kitchen, both people move on, and the transfer of the house is left for later. Later arrives after the deadline. A de facto property settlement left on a handshake is not a settlement, however well the two of you are getting on.

If you are on the receiving end of a threat rather than making a claim, the deadline works for you as well. Former partners who talk about a payout for years without ever filing are common, and the claim does not stay live indefinitely.

Evidence decays alongside rights. Bank records get harder to obtain and recollections of who paid for the renovation stop matching.

What happens if the two years have already passed?

You apply for leave. Filing a de facto property settlement out of time is not impossible, but it requires the court’s permission under section 44(6), argued as a separate question before the substance of the claim is looked at. The formal step is an application for leave to commence a de facto property proceeding out of time.

The threshold is hardship, either to you or to a child of the relationship. The court also wants to know why the delay happened, whether the other person has been prejudiced, and whether the claim has enough substance to be worth reviving. A modest claim with a thin explanation for a three-year delay is a difficult application. A claim over the family home, where the delay came from illness, or an agreement never formalised, is a different conversation.

There is another route that gets overlooked. A binding financial agreement under section 90UD can be made after a de facto relationship has broken down, and it is not subject to the two-year deadline. Where both of you still agree on the outcome, it can be documented and made binding, provided each person gets independent legal advice, and the formal requirements are met. Missing the de facto property settlement time limit is sometimes recoverable this way, without a fight.

One caution on consent orders. If you both agree and want to file after the deadline, leave is still required. Consent does not remove it, although it makes the application a simpler one.

The deadline works differently for married couples

This is where the two systems genuinely part ways, and it surprises people who assume a long de facto relationship is effectively a marriage.

A married couple has no property clock running at all until a divorce order is made. Once it takes effect, they have twelve months. A couple separated for six years who never divorced can still apply as of right. A de facto couple separated for two years and a day cannot.

So the assumption that a decade together makes it “basically a marriage” gets the substance roughly half right and the timing badly wrong. A de facto relationship property settlement runs on the same four-step approach. The deadline does not work the same way, and it is the de facto partner who has less room to move.

Where to from here

If you separated within the last two years, fix your separation date and work out how much of the de facto property settlement time limit is left before negotiating anything. Past it, the question is whether a de facto property settlement out of time is realistic, or whether a binding financial agreement is the better path.
