What is a de facto relationship?
For family law purposes, a person is in a de facto relationship with another person if they:
- Are not legally married to each other
- Are not related by family, and
- Have a “relationship as a couple living together on a genuine domestic basis”.
Is your relationship considered de facto?
If you have any doubts about whether you are in a de facto relationship you can apply to the court for a determination. In deciding whether parties have a “relationship as a couple”, the court will consider:
- the duration of the relationship
- whether the parties share a common residence or have any joint property
- whether a sexual relationship exists
- the degree of financial dependence or interdependence
- the care and support of children, and
- the degree of mutual commitment to a shared life, including observations from family and friends as to the parties’ relationship.
