Have you heard that living together for six months makes you a de facto partner in Australia? It’s one of the most common myths we hear, and it’s not quite right.
In Australia (including Victoria), there’s no automatic rule that says living together for six months puts you in a de facto relationship. Generally, the law recognises a de facto relationship after two years. But there are exceptions, especially if you have a child together or one partner has made significant contributions that would make it unfair not to divide property.
Understanding where you stand legally can make a big difference, especially if you’re separating, considering a property settlement, or just wanting clarity.
What is a de facto relationship?
Under the Family Law Act 1975, a de facto relationship is defined as a couple (of any gender) who live together on a genuine domestic basis. You don’t need to be married, and you don’t even need to live together full-time to qualify.
Courts consider a wide range of factors to determine whether you’re in a de facto relationship, including:
- The length of the relationship
- Whether you live together and for how long
- Financial arrangements and interdependence
- Ownership or use of property
- A mutual commitment to a shared life
- Whether you have or care for children together
- The public perception of your relationship
So the myth about a de facto relationship in Australia being defined by six months of living together doesn’t hold up on its own. Courts look at the full picture, not just a single time frame.
Can you be in a de facto relationship without living together full-time?
Yes. Cohabitation is a factor, but it’s not the only one. What matters is the overall nature of your relationship, your finances, emotional connection, and how you share your lives.
What evidence is used to prove a de facto relationship?
Bank statements, joint leases or mortgages, photos, text messages, declarations to Centrelink or super funds, and shared parenting responsibilities can all be relevant.

The ‘6-month de facto relationship’ theory debunked
There’s no ‘six-month rule’ in Australian law. This idea may come from confusion around different definitions used by organisations like Centrelink or migration departments. But for legal purposes – especially property settlement – it’s a myth.
How long do you have to live with someone before you’re entitled to half?
There’s no hard-and-fast rule. Property isn’t split 50/50 automatically (more on that below). But in most family law cases, you need to show one of the following to determine de facto break up entitlements in Victoria:
- A relationship of at least two years; or
- A child from the relationship; or
- Significant financial or non-financial contributions, like funding major renovations or covering mortgage payments. These are the kinds of things that can make it unfair not to divide property after a breakup.
Can a de facto partner take half your assets?
Not automatically. A de facto relationship doesn’t mean a 50/50 asset split. If you separate and meet the legal threshold for a property claim, the court will consider:
- Each party’s contributions (financial and non-financial)
- Future needs (income, health, caring responsibilities)
- The overall fairness of the proposed division
This may include superannuation, which can be split as part of a property settlement. For more information, visit our Family Law Services.
Difference between de facto and domestic partner or registered relationship
These terms are often used interchangeably, but they’re not the same.
- De facto partner: Someone you live with in a genuine domestic relationship, but aren’t married to.
- Domestic partner: A broader term sometimes used in public policy to include both de facto and registered partners.
- Registered relationship: A formal relationship recorded with Births, Deaths and Marriages in your state.
Do I need to register my de facto relationship in Victoria?
No, but it can help. While registration isn’t required for a relationship to be legally recognised, it can strengthen your position for things like migration, estate planning and Centrelink claims.
Your rights after separation
If your de facto relationship ends, you generally have two years from the date of separation to make a property or spousal maintenance claim.
What rights do I have if we separate before 2 years?
You may still be eligible for a property settlement if:
- You have a child together; or
- You made significant contributions (e.g. financial support, unpaid care) and would suffer hardship without a settlement.
This is a nuanced area, so it’s important to get advice early. Contact our team to find out where you stand.
Protecting yourself: legal and practical tips
It’s never too early to get clear on your legal rights. Whether you’re moving in together or planning for the future, a few simple steps can make a big difference:
- Consider a binding financial agreement (prenup): These can clarify how assets will be divided if the relationship ends. Learn more about binding financial agreements.
- Keep records: Maintain documentation of financial contributions, asset ownership and shared expenses.
- Get advice early: The earlier you seek legal guidance, the more options you have to protect yourself.
Understanding your de facto rights to assets
There’s no such thing as a six-month shortcut to a de facto claim, but that doesn’t mean your relationship isn’t legally significant. Whether you’re starting out or separating, understanding your rights can help you make informed decisions and protect what matters most.
