    Annulment

    What is an annulment?

    An application for an annulment (also called a decree of nullity) is an application for a court order that a marriage be declared invalid.

    On what grounds can a marriage be declared invalid?

    Invalidity may result from any one of the following:

    • either partner was not of marriageable age
    • bigamy (that is, one partner was already married at the time of the marriage ceremony)
    • the people were within a prohibited relationship (for example, they were siblings or parent and child)
    • either or both of the parties did not consent (the marriage took place through fraud, duress, mistake or mental incapacity)
    • the ceremony was invalid (for example, the celebrant was not properly appointed).

    Can a party to an annulled marriage remarry?

    Partners to a void or invalid marriage may remarry at any time without entering a bigamous relationship [Family Law Act 1975 (Cth) s 71].

    Can a party to an annulled marriage still apply for orders about children or property?

    A partner to a void (annulled) marriage may still institute proceedings in the Family Law Court for orders about children, maintenance and property [Family Law Act 1975 (Cth) s 71].

    A child of a void marriage is covered by the Family Law Act 1975 (Cth) [ss 60E, 60F].
