Family Law Act 1975

If:

the parties to a marriage make a written agreement with respect to any of the matters mentioned in subsection (2); and

at the time of the making of the agreement, the parties to the marriage are not the spouse parties to any other binding agreement (whether made under this section or section 90B or 90D) with respect to any of those matters; and

the agreement is expressed to be made under this section;

The matters referred to in paragraph (1)(a) are the following:

how, in the event of the breakdown of the marriage, all or any of the property or financial resources of either or both of the spouse parties at the time when the agreement is made, or at a later time and during the marriage, is to be dealt with;

the maintenance of either of the spouse parties:

during the marriage; or

after divorce; or

both during the marriage and after divorce.

For the avoidance of doubt, a financial agreement under this section may be made before or after the marriage has broken down.

A financial agreement made as mentioned in subsection (1) may also contain:

matters incidental or ancillary to those mentioned in subsection (2); and

other matters.

A financial agreement (the new agreement) made as mentioned in subsection (1) may terminate a previous financial agreement (however made) if all of the parties to the previous agreement are parties to the new agreement.
