Your ex is saying the relationship never existed, or never amounted to anything serious. You know that’s wrong. But knowing it and being able to demonstrate it to a court are two very different things.
That gap is where a lot of people get hurt. Not because their relationship wasn’t real, but because they assumed the reality of it would be obvious. It often isn’t, especially when one person is motivated to deny it.
The law doesn’t accept your word against theirs. It looks at evidence: what you did, how you lived, what records exist, and what the people around you saw. The picture that evidence paints is what decides whether you qualify for a property settlement, a share of superannuation, or spousal maintenance.
The question worth sitting with before you read further: do you actually know what records of your relationship exist, and where they are right now?
This article walks you through what the law looks for, what evidence carries weight, what happens in the messy situations most articles ignore, and what you can do in the next day or two to protect your position.
Key Takeaways
- A de facto relationship under federal law requires that you lived together as a couple on a genuine domestic basis, assessed across a range of factors, not a single test.
- No single piece of evidence is decisive. Courts look at the overall picture. Gaps in evidence are common and can be worked around if you’re honest and organised.
- The two-year rule matters in two directions. Your relationship generally needs to have lasted at least two years, and you generally have two years from separation to start a property claim.
- Keeping finances separate does not disqualify you. Many genuine de facto couples keep separate accounts and separate names on documents. The law looks well beyond bank statements.
- If your partner denies the relationship, that denial is not the end of the matter. Courts deal with this regularly and assess it on the balance of probabilities using all available evidence.
- Act quickly. Evidence, especially digital evidence, disappears. Getting organised now, before things are deleted or disputed, is the most useful thing you can do tonight.
What counts as a de facto relationship under the Family Law Act?
The test comes from section 4AA of the Family Law Act 1975. It asks whether you and your partner were living together as a couple on a genuine domestic basis, were not married to each other, and were not related by family.
The Act lists circumstances a court may take into account when making that assessment. These include:
- the duration of the relationship
- the nature and extent of common residence
- whether a sexual relationship existed
- the degree of financial dependence or interdependence and any financial support between you
- the ownership, use and acquisition of property
- the degree of mutual commitment to a shared life
- whether the relationship was or is registered under a state or territory law
- the care and support of children
- the reputation and public aspects of the relationship
No single factor is determinative. A court weighs all of them together. A couple that kept separate bank accounts but shared a home, raised children together, and were known to friends as a couple will almost always satisfy the test. A couple that ticked every box on paper but maintained entirely separate lives may not.
The Acts Interpretation Act 1954 (Qld) contains its own definition of de facto partner for state law purposes, which overlaps significantly with the federal test. For property settlement, spousal maintenance and superannuation splitting, the federal Family Law Act applies.
Key Point: The law does not measure relationships against an ideal. It looks at the texture of how you actually lived. That is both its limitation and its strength when your situation is complicated.
Why does proving a de facto relationship matter for your rights?
If you cannot establish that you were in a de facto relationship, you cannot access the property settlement, superannuation splitting and spousal maintenance provisions of the Family Law Act.
Those entitlements are significant. A property settlement can include the family home, investment properties, savings, superannuation, business interests and debts. Spousal maintenance can provide financial support during or after proceedings. Without proving the relationship, none of that is available to you.
This is why a partner who wants to minimise or deny the relationship has a financial reason to do so. Saying “we were just housemates” or “it was casual” is not just an emotional denial. It is often a legal strategy.
The two-year limitation period adds urgency. Once you separate, you generally have two years to start de facto property proceedings in the Federal Circuit and Family Court of Australia. After that, you need the court’s permission to proceed, which is harder to obtain and not guaranteed.
Expert Tip: If you’re approaching the two-year mark from separation, get advice now. Waiting even a few weeks can shift your position from a right to a discretion, and that matters.
Do you even need to prove the relationship, or is it already accepted?
In many separations, neither party disputes that they were de facto. They may disagree about assets, contributions or parenting, but not about the relationship itself. If that’s your situation, the question of proof sits quietly in the background and rarely becomes a courtroom issue.
But if your former partner denies the relationship, minimises it, or claims it never met the legal threshold, you will need to establish it before the court can deal with anything else.
You may also need to prove it if you are seeking orders and the other side disputes the length of the relationship, the date of separation, or whether you were living together at all during key periods.
Even in uncontested matters, having your evidence organised helps. Consent orders and financial agreements are stronger when the factual foundation is clear.
Key Point: Most de facto separations do not require a formal hearing on the question of whether the relationship existed. But when it’s disputed, it becomes the first thing the court must resolve, and you need to be ready.
How does the law decide if you were living together on a genuine domestic basis?
This phrase sits at the heart of the test, and it is deliberately broad. Courts are not looking for a perfect domestic arrangement. They are looking for a relationship that had the character of a committed partnership, even if it didn’t look conventional.
Some questions a court might consider:
- Did you share a home, even if not continuously?
- Did you treat each other’s home as your own?
- Did you share domestic responsibilities such as cooking, cleaning or caring for children?
- Did you make financial decisions that took each other into account, even without shared accounts?
- Did you refer to each other as partners, and did others understand you to be a couple?
- Did you support each other during illness, loss or financial hardship?
Periods of separation, including breaks in the relationship or time spent apart for work, do not automatically defeat the claim. Courts look at the overall pattern.
What courts are suspicious of is selective reconstruction. If the evidence suggests the relationship was genuine for years but your partner only started calling it casual when money was at stake, that inconsistency does not go unnoticed.
Expert Tip: Write down a timeline of your relationship while it’s fresh: when you met, when you first lived together, when and why you spent time apart, and when you consider the relationship to have ended. A clear, honest timeline is more useful than you might think.
What evidence can you use to prove a de facto relationship existed?
Evidence of a de facto relationship falls into three broad categories: documents, digital records, and people.
Documents worth locating:
- Lease agreements or mortgage documents showing a shared address, even if only one name appears
- Utility bills, rates notices or insurance policies
- Bank statements, even from separate accounts, showing shared expenses or payments between you
- Joint or overlapping Centrelink or Medicare records
- Tax returns that list your partner’s details
- Superannuation or insurance beneficiary nominations naming each other
- Medical or emergency contact records
- Joint travel bookings or shared accounts with delivery or subscription services
Digital records:
- Text messages and messaging app conversations
- Emails discussing shared decisions, finances, children or plans
- Photos with dates and location data
- Social media posts where you appear together or acknowledge the relationship, even if accounts were private
- Shared calendar apps, grocery apps or streaming accounts
- Booking confirmations for holidays, events or accommodation
People:
- Friends and family who saw you together and understood you to be a couple
- Neighbours who can speak to your living arrangements
- Colleagues who knew you as partners
- Medical professionals who dealt with you both
- Anyone you listed as a reference using the other’s details
Courts assess this evidence on the balance of probabilities. You don’t need to prove your case beyond doubt. You need to show it is more likely than not that the relationship met the legal test.
Expert Tip: A witness statement from one or two people who knew you as a couple can carry significant weight, especially when documentary evidence is thin. Think about who would speak honestly and clearly about what they observed.
Does living together for two years automatically make you de facto?
No.
Two years of cohabitation is a common threshold that appears in the Family Law Act as one of the gateways to bring a property claim. But it is not automatic, and it is not the only gateway.
The law also provides that the two-year requirement can be bypassed if there is a child of the de facto relationship, or if one party made substantial contributions and it would be unjust not to make orders.
Living together for two years without those other factors doesn’t automatically establish the relationship either. You still need to satisfy the genuine domestic basis test. Two people sharing a house as friends or housemates for three years are not de facto partners.
The two-year rule also matters for limitation purposes. Once you separate, you generally have two years to apply for property orders. That clock starts on the date of separation, which is itself sometimes disputed.
Key Point: Two years is a threshold, not a guarantee. The law asks what the relationship was like, not just how long it lasted.
We kept our finances separate. Can we still prove we were de facto?
Yes, and this question comes up constantly.
Many genuine de facto couples keep entirely separate bank accounts, separate names on the lease, separate tax returns, and separate everything on paper. That is more common than most articles acknowledge. It doesn’t mean the relationship wasn’t real.
What matters is whether your financial lives were connected in practice, even if not on paper. Paying each other’s rent in cash, splitting groceries informally, covering each other’s expenses during hard times, making decisions about savings or purchases together: all of that is relevant even without a joint account.
The same applies to property. If only one name appears on the mortgage but the other partner contributed to repayments, renovations or household costs that freed up the mortgage holder’s income, that contribution counts. It may not appear in a bank statement, but it can be established through evidence of how you lived.
Courts are experienced at dealing with cash economies, informal arrangements and relationships that kept a deliberately low administrative profile. The absence of a joint account is not fatal.
Expert Tip: If your financial contribution was mostly in kind, for example, cooking, cleaning, caring for children, managing the household, write down what you did and how often. Contributions to a relationship take many forms, and courts recognise that.
Is a de facto relationship treated differently from marriage?
For property settlement purposes, the rights of de facto partners under the Family Law Act are very similar to those of married couples. Courts apply the same four-step framework, considering the asset pool, contributions of both parties, future needs, and whether the outcome is just and equitable.
Superannuation can be split. Spousal maintenance can be ordered. Property orders can be made in relation to assets held in one party’s name.
There are a few practical differences. The two-year relationship threshold and the two-year limitation period from separation apply to de facto couples but not to married couples. Married couples can apply for a divorce, which is a formal legal event. De facto couples do not divorce, but they do separate, and the date of separation matters just as much.
For parenting arrangements, the distinction between married and de facto is irrelevant. The Federal Circuit and Family Court of Australia applies the same best interests test regardless of whether the parents were married, de facto or never in a committed relationship at all.
Key Point: If you were de facto, you are not a second-class claimant. Your property rights under the Family Law Act are substantively the same as a married person’s.
What if only one of us says we were in a de facto relationship?
This is one of the hardest situations, and it’s more common than people expect.
When a former partner denies the relationship existed or argues it never reached the level of a genuine de facto partnership, the court has to decide who to believe, on the balance of probabilities.
That is not a comfortable process, but it is a workable one. Courts are not naive about the financial motivation behind a denial. A person who spent years presenting themselves as your partner to friends, family and institutions but now claims you were housemates faces a significant credibility problem.
What helps most in this situation is evidence that was created during the relationship, not after it ended. Messages from three years ago calling each other “babe” or discussing what to do with the house have more weight than anything either of you says in court. Emergency contact forms, insurance nominations and Centrelink records from the time of the relationship are particularly useful because they reflect decisions made without any litigation motive.
People who knew you as a couple are also valuable. A former colleague who attended your birthday dinner at which your partner gave a speech, or a neighbour who saw you leave together every morning for four years, can say clearly what they observed without being accused of loyalty bias.
Expert Tip: When a former partner is denying the relationship, your instinct may be to gather everything you can as quickly as possible. That’s right. But be careful about how you go about it. Taking screenshots of shared accounts, saving photos, printing emails: all of that is fine. Accessing accounts you are not authorised to access is not. Get advice before you do anything you’re unsure about.
How do children and parenting arrangements affect proving a de facto relationship?
Having a child together affects your de facto claim in two distinct ways.
First, it is one of the circumstances a court considers when assessing whether a genuine de facto relationship existed. A couple who had a child together, raised that child in a shared home, and made parenting decisions jointly presents a strong picture of mutual commitment to a shared life.
Second, having a child together can satisfy the exception to the two-year relationship threshold. If you were together for less than two years but have a child of the relationship, you can still access de facto property settlement provisions.
On the parenting side, the law is clear: it doesn’t matter whether you were married, de facto, or in no formal relationship at all. The Federal Circuit and Family Court of Australia makes parenting orders based on the best interests of the child. Both parents have equal standing to seek parenting orders, regardless of relationship status.
What changes when there has been a de facto relationship is the financial picture around the parenting arrangements. A parent who made career sacrifices to care for children during the relationship has a stronger argument for spousal maintenance and a favourable property split. Those matters sit alongside, but separately from, the parenting proceedings.
Key Point: Your parenting rights exist regardless of whether the de facto relationship is proven. Your property and financial rights depend on it.
What if you never officially moved in together?
You can still be de facto.
The law requires that you lived together on a genuine domestic basis, but it does not require that you had one shared address listed on a lease or a rates notice. Some genuine de facto couples maintain separate formal addresses while functionally living together. Others spend significant time at each other’s homes across multiple years.
The question is whether, looking at all the circumstances, the relationship had the character of a committed domestic partnership. Courts have found de facto relationships to exist where partners maintained separate addresses but spent most nights together, shared domestic tasks, supported each other financially, and were known by others to be a couple.
What you will need in that situation is evidence of the functional reality. Phone location data, receipts, messages, photos, witness statements and records of shared decision-making can all help paint that picture.
The harder scenario is a relationship that was genuinely part-time throughout. Two people who saw each other on weekends, kept entirely separate lives, and never made decisions jointly may not meet the test, even over a long period. The answer depends on the specifics.
Expert Tip: If you never formally lived together, the documentary evidence of shared domestic life matters more, not less. Start by thinking about every practical way your lives were connected.
Does registering your relationship in Queensland help prove it?
Yes, significantly.
Queensland allows couples to register their relationship through the Births, Deaths and Marriages Registration Office. A registered relationship is treated as conclusive proof that a de facto relationship existed for the purposes of Queensland state law, and carries significant weight in federal proceedings under the Family Law Act.
If you registered your relationship, you do not need to prove the other factors. The registration itself is the evidence.
The limitation is that most couples don’t register. Registration is less common than marriage and not widely promoted. If you did register, locate that certificate and keep it safe. If you didn’t, that’s normal, and the other forms of evidence remain fully available.
Key Point: A registered relationship is the strongest single piece of evidence you can have. If you have one, use it.
What time limits apply to de facto property claims?
Two years from the date of separation.
That is the general rule under the Family Law Act for de facto couples seeking property orders. If you do not apply within two years of separation, you need leave of the court to proceed. The court can grant that leave, but it requires you to show that you would suffer hardship if leave is refused. That is an additional burden, and there is no guarantee it will be granted.
The date of separation is not always obvious. A couple can separate while still living under the same roof. What matters is the communication and conduct that shows one or both parties regarded the relationship as over. A clear conversation, a change in sleeping arrangements, one person leaving or being asked to leave, all of these can mark the date of separation.
Where the date is disputed, the court will examine the evidence and make a finding. That finding then anchors the two-year clock.
If you are unsure whether the time limit is running or has already passed, get advice promptly. This is not an area where waiting helps.
Expert Tip: If you’re not sure exactly when you separated, write down your best recollection of what happened and when. The date you can support with evidence is often more important than the date you feel was correct.
How do you collect and organise evidence without making things worse?
Start with what you already have access to.
Save copies of documents you’re legally entitled to access: your own bank statements, utility bills in your name or at your shared address, emails in your own account, messages on your own phone, photos in your own gallery. Save them somewhere secure, such as a personal email address, a private cloud account, or a USB drive you keep offsite.
Screenshot conversations before they’re deleted. If you’re concerned that a shared account will be locked or that messages will be removed, save them now. The date and context of a message matters, so don’t edit or crop in a way that removes that information.
Write a timeline while your memory is fresh. Note when you met, when you started living together, when significant events happened, and when and how the relationship ended. This doesn’t need to be a formal document. A clear, honest set of notes is enough to start with, and your lawyer can help you refine it.
Do not access accounts, devices or records you’re not authorised to use. Evidence obtained that way can be inadmissible and may have other consequences. If you think important evidence is held in accounts you can’t access, raise that with your lawyer. There are proper processes for obtaining disclosure.
If you’re worried about family violence, including coercive control or monitoring of your devices, get advice before you start collecting evidence. There are safe ways to do this.
Expert Tip: Your lawyer can help you identify what to gather and how to gather it properly. Getting advice early means you don’t inadvertently damage your own case while trying to protect it.
Can social media, photos and messages really prove a de facto relationship?
Yes, and they often carry significant weight.
A message from two years ago where your partner refers to you as their partner, discusses your joint finances, or talks about moving in together is evidence created without any litigation motive. Courts give that kind of contemporaneous evidence considerable weight.
Photos with location and date data can establish that you were together at a shared residence, on holidays, at family events, over a sustained period. Social media posts where one of you is tagged at the other’s address, or where you appear together at significant events, form part of the picture.
Private messages are often the most valuable. A conversation where your partner discusses paying half the mortgage, organises their mail to come to your address, or talks about what to do with shared furniture after separation can directly address the genuine domestic basis question.
The same applies to what isn’t there. If your partner is now claiming the relationship was casual but their own messages throughout the relationship suggest otherwise, that inconsistency is useful.
Key Point: Evidence created during the relationship, before any dispute arose, is almost always more convincing than anything said or done after separation. Save what you have while you can.
What happens if there was family violence or coercive control?
Family violence changes several things in practical terms, and it is worth understanding how.
First, a controlling partner may have deliberately limited your access to financial records, accounts, property and social connections. That kind of isolation can leave you with little documentary evidence of the relationship. Courts are aware of this pattern, and the absence of evidence in a relationship marked by control is assessed differently from a voluntary choice to keep things informal.
Second, if you are at immediate risk, protecting yourself comes before gathering evidence. Safety first. Services such as DVConnect in Queensland can help.
Third, if you have a domestic violence order in place or are seeking one, that process runs through the Queensland Magistrates Court. It operates separately from the Family Law Act proceedings, though both may be happening at the same time. Your lawyer can help you manage both.
Fourth, evidence of family violence, including controlling behaviour, is relevant to the property settlement. Courts consider the impact of violence on contributions, on future needs, and on the overall just and equitable assessment.
Expert Tip: If you’re in a situation involving control or violence, don’t try to manage the evidence-gathering alone. Get advice from a family lawyer who understands both the safety and the legal dimensions. They work together, not separately.
What should you do in the next 24 hours?
Three things, done calmly.
First, save what you have. Spend an hour going through your phone, your email and your documents and copying anything that shows the relationship was real. Bank statements, messages, photos, emails, bills at your shared address. Save them somewhere your former partner cannot access or delete.
Second, write a timeline. Open a notes app or a document and write down the key dates: when you met, when you moved in together or started spending most of your time together, when significant events happened, when things changed, and when you consider the relationship to have ended. Keep it factual. Emotions can come later.
Third, get advice before you do anything that could complicate your position. Don’t have a conversation with your former partner about the relationship or its legal status without understanding where you stand. Don’t agree to anything, sign anything, or move out of shared property without knowing what that means for your claim.
The next few weeks matter more than most people realise. Evidence that exists today can be gone by next month. The date you act from becomes part of your story.
If you are worried tonight that your former partner will deny the relationship existed, or that you don’t have enough evidence, speak to a family lawyer before that concern becomes a crisis. Early advice is almost always cheaper, and almost always better, than late advice.
How long does a de facto separation usually take to resolve?
Where both parties accept the relationship existed and want to reach an agreement on property and parenting, a negotiated outcome can be reached in weeks or a few months. Formalising that agreement through consent orders adds some time but is manageable.
Where the relationship itself is disputed, or where the parties cannot agree on the asset pool, contributions or parenting arrangements, proceedings in the Federal Circuit and Family Court of Australia can take 12 to 24 months or longer, depending on the complexity of the matter and the degree of conflict.
What tends to extend timelines is not the legal complexity but the degree of dispute. If your former partner is determined to deny the relationship or refuse disclosure, proceedings take longer and cost more.
Early, focused legal advice usually shortens the process. Knowing what your position is and what evidence you have allows you to approach negotiations with clarity, which tends to produce faster outcomes.
Expert Tip: The goal is a resolution you can live with, reached as efficiently as possible. That goal is best served by understanding your position early and not waiting until the time limit is nearly up.
What will it cost to get legal help?
The honest answer is that it depends on what needs to be resolved and how much conflict is involved.
A straightforward matter where both parties accept the relationship and broadly agree on terms will cost significantly less than a contested hearing where the relationship itself is in dispute and disclosure is resisted.
We don’t publish fixed fee structures here because they change and because no two matters are the same. What we can tell you is that early advice, before positions harden and before evidence is lost, is consistently more cost-effective than advice sought after things have deteriorated.
At your first appointment with C + K Family Lawyers, we’ll give you a realistic picture of what your matter involves, what the likely process looks like, and what you can expect in terms of cost and time. There’s no obligation to proceed, and nothing is committed from a single conversation.
If cost is a concern, say so. It is a legitimate concern and one we take seriously when helping you think through your options.
Key Point: Getting advice is not committing to litigation. It is finding out where you stand. That is always worth doing, and the cost of the first conversation is almost never the number people fear.
Frequently asked questions
We were together for 18 months and don’t have a child together. Do I have any rights?
The general two-year threshold means that without a child or significant contributions making it unjust to deny you access, a relationship of 18 months may not meet the gateway for de facto property settlement under the Family Law Act. That is worth discussing with a family lawyer before assuming the answer is no. The circumstances matter, and the facts are not always as straightforward as they first appear.
My former partner is claiming we only lived together as housemates. How do I counter that?
With evidence created during the relationship. Messages, photos, records naming each other as partners, witness statements from people who knew you as a couple, and financial records showing a shared domestic life. Courts are familiar with this kind of denial and assess it against the whole picture.
What if most of our relationship was in my partner’s name, their house, their accounts, their car? Have I lost my entitlements?
Not necessarily. The law looks at contributions in their broadest sense, including non-financial contributions such as homemaking, caring for children, and supporting a partner’s career or business. The absence of joint assets is a starting point, not an ending point.
Can I still prove the relationship if we kept it private and weren’t out to our families?
Yes. Courts recognise that some couples, including same-sex couples, kept their relationship private for personal or cultural reasons. The emphasis shifts to documents and digital evidence, and to people who did know: close friends, colleagues, medical professionals, or anyone you trusted enough to be honest with.
Do I have to go to court to sort out my de facto separation?
Not necessarily. Many de facto separations are resolved through negotiation or mediation, with consent orders formalising the outcome. Court proceedings become necessary when agreement can’t be reached or when one party acts in a way that makes informal resolution unworkable. Your family lawyer can help you assess which path makes sense given your circumstances.
Where to from here
If you’re uncertain whether the law will recognise your relationship, worried about evidence that may disappear, or dealing with a former partner who is rewriting history, the most useful thing you can do is have a clear conversation with an experienced family lawyer.
At C + K Family Lawyers, we work with people at exactly this point, when the situation is still uncertain and the decisions you make in the next few weeks can genuinely change the outcome.
If you’d like to talk through your circumstances, reach out to the C + K Family Lawyers team for a confidential, no-obligation initial conversation. We’ll give you a straight answer about where you stand.
The relationship was real. Let’s make sure the law knows that too.
