has done so for 12 months immediately before filing for divorce. Neither spouse can remarry before the divorce becomes final, which is usually one month and one day after the divorce is granted in court. Such a marriage would constitute bigamy and would be illegal and void. If there are children of the marriage aged under 18, a court can only grant a divorce if it is satisfied that proper arrangements have been made for them. A child of the marriage includes: any child of either spouse, including a child born before the marriage or after separation, any child adopted by the spouses or either of them, or any child who was treated as a member of the family prior to the final separation; for example, a step-child or foster child. A copy of the marriage certificate must be provided with the application.

After the divorce is finalised, each party can apply to the Federal Circuit and Family Court of Australia (or the Family Court of Western Australia for residents of that state) for a proof of divorce certificate.

Since 2009, the definition of "de facto couple" under the federal Act has included same-sex couples and applies throughout Australia, except Western Australia. A de facto couple must cohabit for a minimum of two years for the Family Law Act to apply, unless if they have a child together, have registered the relationship, or have made significant contributions to the relationship. Parties to a de facto relationship have only two years after separation in which to file for property and/or spousal maintenance in the Family Court. Before March 2009, state and territory laws applied to de facto relationships (and continues to apply in Western Australia). The names for de facto and similar relationships in each state and territory were/are as follows: Recognition outside Australia Because of how the power from state or territory
