How to Prove a De Facto Relationship

6th May 2021

De facto couples have many of the same rights and obligations as married couples when they separate. The RMB Family Lawyer division explains how a de facto relationship is defined under the Family Law Act:

To be able to seek orders for a property adjustment when they separate, parties to a de facto relationship must first show that they were in fact in a de facto relationship so as to invoke the jurisdiction of the Court under the Family Law Act.

Demonstrating the existence of a de facto relationship can prove more complex than demonstrating a marriage.

To do so, the party claiming the existence of the relationship must be able to demonstrate that:

  1. The persons are not legally married to each other;
  2. The persons are not related by family; and
  3. Having regard to all the circumstances of their relationship, they have a relationship as a couple living together on a genuine domestic basis. 

To determine the existence of the relationship, and in particular, to satisfy itself as to the third point, a Court will have regard to the following circumstances of the parties’ relationship:

  1. The duration of the relationship;
  2. The nature and extent of the parties’ common residence;
  3. Whether a sexual relationship exists;
  4. The degree of financial dependence or interdependence, and any arrangements for financial support, between the parties;
  5. The ownership, use and acquisition of the parties’ property;
  6. The degree of mutual commitment to a shared life;
  7. Whether the relationship is or was registered under a prescribed law of a State or Territory as a prescribed kind of relationship;
  8. The care and support of children;
  9. The reputation and public aspects of the relationship.

The above is a non-exhaustive list of what the Court may have regard to, and the existence or absence of any of the above factors is not conclusive to the Court finding that a de facto relationship does or does not exist. Importantly, parties do not have to be in a relationship for a requisite period of time in order to establish the existence of a de facto relationship although the duration may assist in proving the de facto relationship.
