Couples who live together and are not married live in what is called a de facto relationship.
Sometimes it is difficult to decide whether a qualifying de facto relationship exists. It can often be important to establish if there is a de facto relationship for the purpose of division of property, either on a relationship breakup or when one partner dies.
It is a matter of whether the couple have a mutual commitment to a shared life together.
The property division regime that applies to married couples similarly applies to couples in a qualifying de facto relationship of three years or more.
For a couple in a de facto relationship that has lasted less than three years, their property may still be divided on a contribution basis, if there is a child of the relationship or one partner has made a substantial contribution to the relationship.
