What is a De Facto Relationship?


A de facto relationship or civil partnership exists where two people are living together as a couple on a genuine domestic basis. Whether a de facto relationship exists in a given situation will be determined by considering all the circumstances.

What the court considers

To establish if two people are in a de facto relationship, the court will consider:

  • the duration of the parties’ relationship;
  • how long the parties have lived together, if at all;
  • if a sexual relationship exists between the parties;
  • the level of financial dependence/co-dependency of the parties;
  • if the parties own property together, or separately;
  • if the parties enjoy the use of one another’s property;
  • if the parties have a commitment to a shared life together, and the level of that commitment;
  • if the relationship is registered as a civil partnership;
  • if the parties have children together;
  • the care arrangements for any children of the relationship, or of either party to the relationship; and
  • the public perception of the parties’ relationship.

The court will carefully think about the collective effect of all of the above factors when it determines whether or not a de facto relationship existed. No single factor is determinative and the overall circumstances of the parties’ relationship will be considered.

Who can be in a de facto relationship?

A Civil Partnership can exist between two people of the same sex or two people of different sexes. A de facto relationship cannot exist between two people who are married to one another or two people who are closely related by blood(such as parent and child or siblings).

A person can be a party to two de facto relationships at the same time. A  person can also be married to one person and simultaneously in a de facto relationship with another person.

Did a de facto relationship exist?

Before the court can deal with a matter under the Family Law Act, it must be satisfied that a de facto relationship existed (if the parties were not married). Usually, establishing that a de facto relationship exists will be a formality because both parties consent to the court’s jurisdiction under the de facto provisions in the Family Law Act.

However in some cases, the issue of whether a de facto relationships existed will be in dispute and the court will have to make a determination. =

For the Family Law Act to apply to a de facto relationship, the court needs to satisfy itself of one of the following:

  • that the parties were a de facto relationship for at least two years; or
  • that the parties have a child together; or
  • that the applicant made substantial contributions to the relationship; or
  • that if the court failed to make the declaration, the applicant would suffer a serious injustice; or
  • the relationship was registered under a prescribed state or territory law, for example the relationship was registered as a Civil Partnership with the relevant authority.

The court may also be asked to make a declaration about the duration of a de facto relationship, when a de facto relationship is taken to have commenced and/or ended. The Family Law Act applies to de facto relationships that have ended on or after 1 March 2009.

When making an application under the de facto provisions of the Family Law Act, it is important to keep in mind that limitation periods and jurisdictional requirements exist.
