De facto relationships are subject to many of the same laws as married relationships. This means that there are many responsibilities and potential liabilities which may apply to you in a de facto relationship, particularly in relation to your share of property, debts, parental responsibility, maintenance, income tax, social security (Centrelink) and superannuation to name a few.
Laws relating to property settlements, maintenance, parenting orders and child support are also the same as those that apply to married relationships. Accordingly, Western Australians in a de facto relationship can use the Family Court to resolve disputes arising from the breakdown of a de facto relationship, provided the de facto relationship between the two parties lasted for at least 2 years. You must bring any application in the Family Court within 2 years of the relationship ending.
