Many couples move in together believing that living together immediately creates a 50/50 entitlement to each other’s assets. It’s a common misconception, and one that can cause unnecessary anxiety or poor financial decisions.
In reality, Australian family law takes a far more nuanced approach. Living together does not instantly merge your property interests. Any entitlement that may arise does so gradually, based on contributions and how the relationship develops.
Simply sharing a home does not necessarily mean the law recognises you as de facto partners. Courts look at a range of factors to decide whether a de facto relationship exists, including:
Only once a de facto relationship is established can either partner seek a property settlement. Even then, the idea of an automatic 50/50 split is still inaccurate.
One of the most misunderstood parts of family law is how interests in each other’s property develop over time. Living together alone doesn’t give a partner an immediate claim over assets owned by the other. Instead, entitlements grow as time goes on and contributions build up.
Courts consider a structured set of factors when deciding how assets should be divided:
This means a partner who owned a home before living together doesn’t automatically lose half of it if the relationship ends. Likewise, a partner who made significant non-financial contributions may receive a larger share than their financial input alone would suggest.
Over time, contributions can increase a partner’s interest in property they do not legally own.
For example:
These contributions build up gradually. Entitlements grow with the relationship, not from the moment you move in together.
One of the most effective tools for clarity and protection is a Binding Financial Agreement (BFA). A BFA is a written agreement about how your property and finances will be dealt with.
A BFA can:
For many couples, a BFA is simply a practical way to make sure both people feel secure and respected.
Moving in together is an emotional milestone, not a legal trigger for a 50/50 division of assets. Australian family law recognises that relationships change over time, and so do property interests. Entitlements grow gradually, based on contributions and the nature of the partnership, not the date you start sharing a home.
