Australian society has long recognised the existence of non-traditional domestic partnerships. This has been reflected across various laws, with de facto relationships holding significant weight from a legal perspective. This can be a confusing area, especially when it comes to understanding what a de facto relationship is and why it matters from a legal stance.
So, why is this important, and what does it mean for you?
This article explains what constitutes a de facto relationship in Australia, how the law determines if one exists, and why this status is so relevant, particularly in family law and financial matters. The information is general only and is not intended to be legal advice. If you need guidance, we recommend consulting an experienced lawyer.
The Latin term “de facto” simply means “in fact” or “in reality”. In a legal sense, it means a couple is living together on a genuine domestic basis, even though they aren’t married.
The definition of a de facto relationship is found in section 4AA of the Family Law Act 1975 (Cth). The Act is a federal law, and its principles are applied across Australia, although some states have their own specific laws that also deal with de facto relationships, particularly in areas outside of family law.
According to the Family Law Act, a person is in a de facto relationship with another person if:
The third point is the one that often requires the most thought, and the law looks beyond simply sharing a house. To determine if a genuine domestic basis exists, a court will consider various factors. No single factor is more important than another, and a court will look at all of them to get a complete picture of the relationship.
These factors include:
The law looks at the combination of these factors to decide whether a de facto relationship exists.
The legal recognition of de facto relationships is a big deal because it grants de facto couples many of the same rights and responsibilities as married couples. This is most obvious in two key areas: family law and financial matters.
For many years, couples who were not married had limited legal recourse if their relationship ended. That changed with reforms to the Family Law Act that came into effect in 2009. These changes gave de facto couples the right to ask a court to make orders about property settlement and spousal maintenance after a relationship breakdown, just like a married couple.
The principles for dividing assets in a de facto relationship are largely the same as for a married couple. A court will consider:
This legal recognition means that if you are in a de facto relationship and it ends, you are protected by the same legal framework as a married couple when it comes to property division.
Beyond family law, being in a de facto relationship can impact a range of other financial and legal areas:
The concept of a de facto relationship acknowledges that many people choose not to marry but still want the same legal protections and recognition as married couples.
If you are in a relationship that you think might be a de facto relationship, it is important to understand your rights and obligations, especially if you are considering buying property together or if the relationship ends. The law’s purpose is to ensure that both partners are treated fairly and that any children of the relationship are properly cared for.
The detailed and comprehensive definition of de facto in the Family Law Act ensures that the unique circumstances of each couple are taken into account, providing a flexible framework for addressing a wide range of situations.
