There is no minimum time you have to live with someone to be in a de facto relationship under Australian family law.
The two year rule is real, but it is not a definition of the relationship. It is one of the gateways to the court hearing a property claim, and there are others: a child of the relationship, or substantial contributions that would make it unjust to leave you with nothing.
What the court actually looks at is the nature of the relationship. How long it ran, whether you lived together, whether your finances were mixed, who owned what, whether there was a sexual relationship, how you cared for children, and how you presented yourselves publicly.
That means an eighteen month relationship can qualify and a five year one can fail, depending on the evidence.
Do you know which side of that line your relationship sits on right now?
This article explains how a de facto relationship is defined, when the two year rule matters, and how people prove one existed when the other party denies it.
Key Takeaways
- There is no fixed minimum time required to be in a de facto relationship under Australian family law. The law looks at the whole picture of how you lived.
- The two-year rule is about claims, not status. You generally need two years of living together, or one of three exceptions, before you can bring a property or maintenance claim.
- Having a child together, or making substantial contributions, can override the two-year threshold and allow you to bring a claim even if the relationship was short.
- You have two years from separation to start a de facto property or maintenance claim. That clock runs whether you know about it or not.
- Parenting arrangements and child support work the same way for de facto couples as they do for married couples. Your children’s situation does not depend on whether you were de facto.
- Early legal advice almost always costs less than waiting. If you’re unsure where you stand, the worst thing you can do is nothing.
What does “de facto” mean under Australian family law?
A de facto relationship, under Australian family law, is one where two people live together as a couple on a genuine domestic basis without being married to each other.
That phrase, “genuine domestic basis”, is doing a lot of work. It’s not about whether you had a lease in both names. It’s not about whether you slept under the same roof every single night. It’s about the substance of your shared life.
The law is federal. It applies the same way across Australia, whether you’re in Brisbane, on the Gold Coast or anywhere else in the country.
Think about what your relationship actually looked like. Did you share finances? Did you spend most of your time together? Did your families and friends know you as a couple? Did you take care of each other when things got hard? Those are the kinds of questions the law is interested in. Not whether you ticked a box on a form.
“De facto” is a description of how you actually lived, not a status you apply for. If you’re unsure whether your relationship qualifies, you’re probably asking the wrong question first. The better question is: what can you actually do about your situation?
How long do you have to live together to be de facto?
There is no minimum period of cohabitation required to exist as a de facto couple.
You could be de facto after six months. You could be de facto after six weeks if the circumstances support it. Duration is one factor courts consider, but it is not the deciding factor.
Now, here’s where people get confused. There is a separate question about when you can actually bring a legal claim for property or spousal maintenance after a de facto relationship ends. That’s where the two-year figure comes in.
To start a property or maintenance claim following a de facto separation, you generally need to show one of the following:
- You and your partner lived together for at least two years in total.
- You have a child together from the relationship.
- You made substantial contributions to the relationship, financial or otherwise, such that it would be seriously unjust not to consider your claim.
- You were in a registered relationship under state or territory law.
So if your relationship lasted 14 months and there are no children and no major contributions, bringing a property claim is harder. But if you moved in after six months, paid the deposit on a house, and are now separating a year later with a toddler, you almost certainly have grounds to make a claim despite the short timeline.
The two-year threshold is a gateway to certain claims. It is not a measure of whether your relationship was real.
Don’t assume a short relationship means no entitlements. If there are children involved, or if you made significant financial or non-financial contributions, get advice before you write yourself off.
Can you be de facto before two years, and does it matter?
Yes, you can be de facto well before two years. The question is what flows from that.
If someone you lived with for eight months says, “we were never de facto, you get nothing,” they may be wrong about the first part and they may be wrong about the second. Courts have found de facto relationships existed in some surprisingly short periods when the circumstances supported it.
What actually matters in those short-relationship situations is whether you fall into one of the exceptions for making a claim. Having a child together is the most common one. If you have a child from the relationship, the two-year threshold effectively falls away for property and maintenance claims.
Here’s a situation that comes up regularly. You moved in together just over a year ago. You have a toddler. You paid most of the deposit on the property you’re now living in. Your partner is saying you weren’t together long enough to have any rights.
In that situation, the child alone is likely enough to get past the two-year gateway. Your financial contributions then become part of how the court works out what a fair property settlement looks like. The length of your relationship matters to that calculation, but it doesn’t shut the door.
A child from the relationship changes the legal landscape significantly. If you and your former partner have children together, the two-year threshold is almost never the end of the conversation.
Does living apart stop a relationship from being de facto?
Not necessarily. This is one of the most misunderstood parts of de facto law.
Modern relationships are complicated. People work FIFO rosters in the mining industry and spend weeks away from home. Defence personnel are posted interstate or overseas. People keep a room at their parents’ place while spending most of their time at their partner’s. Some couples maintain two separate addresses for completely legitimate reasons, financial or otherwise, while sharing a genuine domestic life.
Courts understand this. Physical presence under the same roof every night is not the test. The test is whether, taking everything into account, you were living as a couple on a genuine domestic basis.
Consider this: he stayed at your place four nights a week and kept a room at his parents’ house. His mail still went there. But he paid half your grocery bill, kept clothes at your place, met your family regularly, and introduced you as his partner. That kind of situation can absolutely support a finding of a de facto relationship, even though neither of you would have said you “lived together” in the traditional sense.
What matters is the totality of the relationship, not any single fact about your living arrangements.
If your living situation was unconventional, don’t assume that counts against you. Write down how you actually spent your time together, what you shared financially, and how you presented as a couple to the world. That picture is what matters.
What factors do courts look at when deciding if a couple is de facto?
When there’s a dispute about whether a de facto relationship existed at all, the court looks at a list of factors set out in the Family Law Act.
No single factor is decisive. The court weighs them together.
The factors include:
- How long you lived together.
- The nature and extent of your common residence.
- Whether you had a sexual relationship.
- The degree to which your finances were merged or interdependent.
- Whether you owned or used property together.
- The degree of mutual commitment to a shared life.
- Whether you cared for children together.
- How you were seen publicly as a couple.
- Whether you registered the relationship.
In practice, when someone comes in genuinely unsure whether they were de facto, the first questions are usually about finances and children. Did you have joint accounts? Did you pay each other’s bills? Did you buy property together? Did you have or raise children together? Those facts tend to resolve the uncertainty faster than anything else.
One small detail can sometimes make or break the question. A client who kept their entire financial life completely separate, never introduced their partner as anything more than a friend, and maintained a full separate household may struggle to establish a de facto relationship even after years of spending time together. On the other side, someone who moved in after a few months, merged finances quickly, and had a child can establish de facto status in a short time.
Courts look at the whole picture of how you lived, not a checklist. If several of these factors point in the same direction, the answer is usually clear. It’s the messy middle ground that needs careful legal advice.
What happens to property after a de facto separation?
If your de facto relationship qualifies, the approach to dividing property is the same process that applies to married couples separating. The Federal Circuit and Family Court of Australia follows the same framework.
The court looks at:
- What assets, liabilities and superannuation each of you has.
- What each of you contributed, financially and non-financially, including as a homemaker and parent.
- What each of you needs going forward, taking into account income, health, care of children, and future earning capacity.
- Whether the outcome is just and equitable overall.
There is no automatic 50/50 split. Anyone who tells you that is not giving you accurate information. The outcome depends on the specific facts of your relationship, and those facts vary enormously from couple to couple.
Superannuation is treated as property and can be split between de facto partners, just as it can for married couples.
Spousal maintenance, the ongoing financial support paid from one former partner to the other, can also be available after a de facto relationship ends, provided the eligibility requirements are met.
The property pool includes everything: the family home, investment properties, savings, shares, vehicles, superannuation and business interests. Don’t underestimate what’s actually in the pool before you decide whether a claim is worth pursuing.
How long do you have to make a de facto property claim?
Two years from the date of separation.
That is the standard limitation period for a de facto property or spousal maintenance claim under the Family Law Act. If you miss it, you need the court’s permission to proceed, and that permission is not automatic.
This is where the timing of separation matters enormously. Separation in a de facto relationship doesn’t require any formal step. There’s no paperwork to file. It’s the point at which the relationship genuinely ended, and that date can be disputed.
The most dangerous thing you can do is wait.
Eighteen months after separating, you might feel like there’s still time. There is, but not much. If you’re still sorting through what happened, still grieving the relationship, still hoping things might change, the two-year clock is running regardless.
If you’re approaching the two-year mark and haven’t taken any steps, get legal advice immediately. Not next week.
The limitation period runs from the date of separation, not from the date you decide you want to make a claim. Don’t let the deadline sneak past you while you’re still working out how you feel about everything.
What are you entitled to after a de facto breakup?
There’s no fixed answer to this question, and anyone who gives you one without knowing your full situation isn’t being straight with you.
What you may be able to claim depends on:
- The length of your relationship.
- What you each contributed, financially and otherwise.
- What assets exist.
- Whether there are children.
- Your respective financial positions after separation.
That said, the entitlements available to de facto couples are substantively the same as those available to married couples. Property and superannuation division, spousal maintenance, and parenting orders all operate on the same legal framework.
The most common misconception is that de facto couples are somehow “lesser” in the eyes of the law than married couples. They are not. If your relationship qualifies, you have access to the same protections and remedies.
De facto separation is not a second-tier legal problem. The law treats qualifying de facto couples the same way it treats married couples when it comes to property and parenting. Don’t let anyone tell you otherwise.
What happens to children after a de facto separation?
Parenting arrangements and child support work the same way for de facto couples as they do for separated married couples.
Full stop.
Whether you were married, de facto, or in a relationship that defies easy categorisation, if you have children together, the law’s focus is entirely on what is in the best interests of those children. Your marital status is irrelevant to that question.
In Australia, the law talks about parental responsibility and arrangements for children to “live with” or “spend time with” each parent, rather than custody in the way that term is often used. Both parents generally continue to share parental responsibility after separation, regardless of how they lived together or how long.
Parenting orders are made by the Federal Circuit and Family Court of Australia and apply equally to de facto and married parents.
Child support is calculated and administered by Services Australia using the same formula regardless of whether the parents were married.
If there is family violence in your situation, either as a victim or if you’re concerned about your children’s safety, tell your lawyer at the first appointment. The process looks different in those circumstances, and your safety and your children’s safety come first.
If you’re separating from a de facto partner and you have children, don’t let uncertainty about whether you were “properly” de facto delay you from making arrangements for the kids. Parenting issues don’t wait for the property question to be resolved.
Do de facto couples have to go to court?
Most de facto separations can be resolved without the need for making an application to the court.
The majority of property settlements and parenting arrangements are negotiated between the parties, often with legal help, and then formalised either by consent orders filed with the Federal Circuit and Family Court of Australia, or by a binding financial agreement.
Consent orders give you the security of a court order without having to go to court. They’re the most common way de facto couples finalise their affairs when they can reach agreement.
Going to a full contested hearing is the most expensive and most time-consuming path. It’s also the least predictable. Experienced family lawyers work hard to help clients reach a fair outcome before it gets to that point.
That said, sometimes court is necessary. If your former partner is hiding assets, is refusing to engage, or the stakes are high enough that you can’t afford to accept less than what’s fair, litigation may be the right path. That’s a decision to make with your lawyer, based on your specific circumstances.
Don’t assume court means a hearing. Most of what happens in family law matters, including negotiation, mediation and filing consent orders, happens outside a courtroom. The process is often more manageable than people expect.
How long does a de facto property settlement take?
If both parties are willing to engage and the asset pool is relatively straightforward, a negotiated property settlement can be finalised within a few months.
When things are more complex, when there are business interests, disputed valuations, one party who won’t cooperate, or significant superannuation, the timeline extends. Twelve to eighteen months for a contested matter is not unusual. Fully litigated cases can take longer.
The single biggest driver of time is whether both parties are willing to engage honestly and constructively. When both people are, timelines compress. When one isn’t, they blow out.
Parenting matters are generally resolved more quickly when both parents can agree, and the court prioritises children’s matters when parents cannot.
How much will it cost to sort out a de facto separation?
There is no fixed answer, and anyone who gives you a firm number without understanding your situation should be viewed with scepticism.
What drives cost is complexity and conflict. A matter where both parties are cooperative, the assets are clearly identified, and agreement is reached relatively quickly will cost far less than one involving disputed asset values, hidden finances, or a party who won’t engage.
Early advice is almost always cheaper than delayed advice. Understanding your position clearly from the start tends to reduce the number of steps it takes to get to a resolution.
Before you see a lawyer for the first time, speak to your lawyer about what their fees look like and how they structure their work. A good family lawyer will be straight with you about costs from the first appointment.
Conflict is the biggest driver of legal cost. The more constructively both parties engage, the lower the cost on both sides. That’s worth keeping in mind, even when things feel impossible.
Frequently asked questions
Can I be in a de facto relationship without living together full time?
Yes. The law doesn’t require you to share a roof every night. Courts look at the overall character of the relationship, including financial ties, time spent together, how you presented as a couple, and whether you had children. An unconventional living arrangement doesn’t automatically disqualify you.
What if my partner says we were never de facto?
That’s a factual dispute, and courts resolve them by looking at the evidence of how you actually lived. If your partner is making that claim to avoid a property settlement, get legal advice. The dispute is not resolved by whoever says it loudest.
Does being de facto give me the same rights as being married?
For property settlement, superannuation splitting and parenting arrangements, yes. The legal framework is the same. The main practical difference is the two-year threshold for property claims, and the two-year limitation period from separation.
What if we broke up and got back together more than once?
Periods of cohabitation can be added together. If you separated and reconciled, the total time you lived together as a couple may still satisfy the two-year threshold. This can be a complicated factual question, and it’s worth getting specific advice.
I’ve been separated for nearly two years and haven’t done anything. Is it too late?
It may not be too late, but you need to act now, not next week. The two-year limitation period for property and maintenance claims runs from the date of separation. If you’re close to that mark, contact a family lawyer immediately.
Where does this leave you?
If you’re unsure whether you were de facto, whether you have a claim, or what the two-year clock means for your situation, the answer isn’t to wait and see.
The law gives qualifying de facto couples the same access to property settlement, superannuation splitting and parenting orders as married couples. But those rights come with time limits, and those time limits don’t pause while you’re still working out what happened.
Get clear on where you stand. That’s the first step.
