De Facto Relationships and Money: What You're Actually Entitled To

🏠 What makes a relationship "de facto"?🔗

Under the Family Law Act 1975, a de facto relationship exists when two people live together as a couple on a genuine domestic basis, and they're not married to each other or related by family. Courts weigh a range of factors: how long you lived together, shared finances, a shared household, how you presented as a couple publicly, whether you have children together, and whether you owned or used property together. No single factor decides it, courts look at the whole picture.

🎯 The essential: A court generally needs one of these to even hear a de facto property case: the relationship lasted at least two years, or there's a child of the relationship, or one partner made substantial contributions and a failure to make an order would cause serious injustice, or the relationship was formally registered under state or territory law.

Same-sex couples have been included in this federal framework since 1 March 2009, a significant shift, before that same-sex couples had far fewer protections.

💔 What happens to money and property if you split🔗

De facto couples who separate can generally apply to the Federal Circuit and Family Court of Australia for financial orders under the Family Law Act 1975, the same legislation that governs married couples (Western Australia is the exception for most matters, more on that below). The court works through a four-step process.

1. Identify the asset pool. Everything either person owns, individually or jointly, real estate, savings, shares, vehicles, business interests, and super.
2. Assess contributions. What each person contributed, financially and non-financially, across the relationship.
3. Assess future needs. Age, health, earning capacity, care of children, and financial resources going forward.
4. Check it's just and equitable. A genuine fairness check, not a rubber stamp.

There's an important distinction worth getting straight, because it trips a lot of people up. The two-year relationship length mentioned above is a gateway that decides whether a court can hear your case at all. Separately, once you've separated, there's a time limit on actually filing that application: generally two years from the date of separation, after which you need the court's permission to proceed. These are two different "two years," and confusing them is an easy mistake. The filing deadline applies whether your matter falls under the federal Family Law Act or, if you're in Western Australia, the equivalent state legislation, but exactly how "separation" is defined and how the deadline is calculated can get technical. Don't do this maths yourself, get advice early so you don't accidentally run out the clock.

🤝 What counts as a "contribution"🔗

Courts recognise two broad types of contribution.

What each person owned before the relationship started matters too, especially in shorter relationships. Take a couple together six years, where one partner owned a $180,000 property before they met, the other earned significantly more and contributed more to the mortgage, and the first partner worked part-time and did most of the childcare for their two kids. A court would weigh the pre-relationship property, the higher financial contributions, the non-financial contributions as primary carer, and the future needs of each person, including reduced earning capacity from years of part-time work. The result could land anywhere depending on how those factors are weighed, which is exactly why this needs proper legal advice rather than a rule of thumb.

🏦 What about superannuation?🔗

Super is included in the asset pool for de facto property settlements, and has been since super splitting was introduced nationally in 2002. A superannuation splitting order lets one partner receive a portion of the other's super fund. It doesn't become cash straight away, it stays in the super system until the receiving partner reaches preservation age and meets a condition of release. If one partner has a much larger balance after years of part-time work or career breaks, that imbalance can be addressed in a settlement, and it's worth getting both funds formally valued as part of the process.

💳 What about debt?🔗

Debt is part of the asset pool too. Joint debts, like a joint mortgage or joint credit card, mean both people are legally liable regardless of who spent the money or who "caused" it, a lender doesn't care about your separation agreement. Individual debts generally stay with the person who incurred them, but they can still be factored into how the rest of the property is split. If one partner is walking away with a significant debt, the court may adjust the split to account for it. Practically, close or restructure joint accounts and credit facilities as soon as possible after separation, staying jointly liable for a former partner's ongoing spending is a real risk.

🌏 The Western Australia exception🔗

If you're in WA, this part matters. Other than superannuation splitting, most de facto property matters in Western Australia are handled under the state's own Family Court Act 1997 (WA), not the federal Family Law Act, and by the Family Court of Western Australia rather than the Federal Circuit and Family Court of Australia. The general framework is similar, but there are differences in how threshold requirements and procedure are applied.

Since 28 September 2022, superannuation splitting for WA de facto couples falls under the federal Family Law Act, bringing WA into line with the rest of the country on that specific issue, even though most other property matters still run through the state system. If you're in WA, seek advice from a WA family law solicitor who knows the state legislation, don't assume general information about the federal Act covers your situation completely.

🛡️ If you want to protect your assets🔗

The best time to think about financial protection is before a problem arises. The main tool available to de facto couples is a binding financial agreement, sometimes loosely called a "de facto prenup," though that's not an official legal term. It's a written contract setting out how property and financial resources will be divided if the relationship ends, and it can be made before, during, or after the relationship.

For it to be binding, both parties need independent legal advice from a qualified solicitor before signing, with each lawyer providing a signed certificate confirming it happened. This isn't optional, without it the agreement is vulnerable to being set aside. We've written the full explainer on what a prenup actually is in Australia, including what it can and can't cover.

Money secrecy during a relationship can also complicate a settlement later, since full financial disclosure becomes mandatory once you're separating. If something about your partner's finances feels off well before separation is even on the table, our guide to financial infidelity covers the warning signs and what to do about them.
