What Is a Defacto Relationship in Australia?
In Australia, a defacto relationship is recognised when two people—regardless of gender—live together on a genuine domestic basis but are not legally married to each other.
The Family Law Act 1975 (Cth) sets out the criteria for determining whether a relationship qualifies as defacto. According to the Act, a defacto relationship exists when the couple:
-
are not married to each other.
-
are not related by family.
-
have a relationship that demonstrates a genuine domestic partnership.
Courts assess several factors to determine whether a defacto relationship exists, including:
-
Mutual commitment: Whether both parties intended to maintain a long-term, committed relationship.
-
Living arrangements: Whether they share a residence, noting that temporary separations do not necessarily end the relationship.
-
Financial aspects: Whether they share finances or if one person is financially dependent on the other.
-
Social aspects: Whether the relationship is publicly recognised—for example, being acknowledged as a couple by friends and family.
-
Sexual relationship: While common, it is not an essential factor.
Australian law also recognises same-sex couples and relationships where partners may not live together full-time but still meet other requirements for recognition as defacto.
Legal Status and Rights of Defacto Couples in Australia
Defacto couples have many of the same legal rights and responsibilities as married couples, particularly under the Family Law Act 1975 (Cth). These rights apply to property division, partner maintenance, and arrangements for children.
Property Settlements
Defacto couples can apply for property settlements in the Federal Circuit and Family Court of Australia. When dividing assets, the court considers:
-
Financial contributions (such as income, investments, and savings).
-
Non-financial contributions (such as homemaking, child-rearing, or maintaining property).
-
Future needs (such as age, health, and earning capacity).
-
Special circumstances that may justify an unequal division of property.
Applications for property settlements must be made within two years of the relationship ending. In special circumstances, the court may grant an extension.
Example Case Scenario
Consider a Queensland couple, Sam and Casey, who were in a defacto relationship for six years. They purchased a home together—Casey contributed more to the deposit, while Sam paid most of the mortgage. When they separated, the court assessed both financial and non-financial contributions, including Sam’s care of their two children, to decide a fair division of property.
This illustrates that courts assess both tangible and intangible factors when dividing assets in defacto matters.
Defacto Relationships and Children
When defacto partners have children together, their parental rights and responsibilities are identical to those of married parents.
Disputes about parenting, child support, and care arrangements are typically resolved through family dispute resolution before going to court. The goal is to reach mutual agreements that protect the child’s best interests.
Under the Child Support (Assessment) Act 1989 (Cth), the Child Support Scheme, managed by Services Australia, determines the amount of child support payable based on each parent’s income and care percentage.
Defacto parents can also make private child support agreements that set out specific arrangements for care and financial support.
Registered Relationships in Australia
Some Australian states and territories allow couples to formally register their relationship. Registration provides legal proof of a relationship similar to a marriage certificate.
Benefits of Registration
-
Simplifies proving the existence of a defacto relationship in property or maintenance cases.
-
Can assist in accessing entitlements, benefits, or next-of-kin rights.
Registration is not mandatory but can be advantageous when dealing with legal or financial matters.
Financial and Property Disputes
When a defacto relationship ends, financial and property disputes can arise. Australian courts resolve these matters by assessing:
-
Financial and non-financial contributions by each party.
-
The care of children and ongoing financial needs.
-
The overall fairness of the proposed division.
Time limits apply—applications for property settlement or maintenance must generally be filed within two years after separation.
Mediation and Dispute Resolution
Mediation is encouraged before court proceedings begin. It allows both parties to resolve disagreements cooperatively and privately.
Key Benefits of Mediation
-
Cost-effective: Significantly cheaper than going to court.
-
Faster resolution: Agreements are often reached more quickly than through formal hearings.
-
Confidentiality: Mediation discussions remain private.
-
Control: Both parties participate in shaping the outcome.
-
Reduced stress: Encourages constructive communication and long-term cooperation, especially when children are involved.
If mediation fails, the case can proceed to the Federal Circuit and Family Court of Australia, where a judge will make a binding decision.
Frequently Asked Questions (FAQs)
What is the minimum time period for a defacto relationship?
There is no fixed time, but duration is one of several factors courts consider when determining whether a defacto relationship exists.
Can same-sex couples register their relationship?
Yes. Same-sex couples have equal rights to register their relationship and access the same legal protections as opposite-sex couples.
What happens if we can’t agree on property division?
If mediation fails, the court will decide based on contributions, needs, and fairness under the Family Law Act 1975.
Do defacto couples have the same child support obligations as married couples?
Yes. Both parents share equal responsibilities for financial support under the Child Support Scheme.
Is registration of a defacto relationship required?
No, but registration provides clear legal evidence of the relationship, which can assist in resolving disputes.
Can I apply for property settlement after two years?
Only in exceptional circumstances. The court must be satisfied that hardship would result if permission were denied.
Can defacto couples make financial agreements?
Yes. Financial or “binding financial agreements” can outline how assets will be divided if the relationship ends, provided they meet formal legal requirements.
