Part V of the Family Law Act provides that spouses or prospective spouses may enter into a marriage contract or cohabitation agreement with respect to property and support obligations on termination of their marriage or cohabitation. Such a contract cannot determine the right of custody of children following the separation of the parties nor can it limit a spouse’s right to possession of the matrimonial home. A marriage contract is a domestic contract by virtue of the Family Law Act. Domestic contracts may be filed with the court, allowing their support provisions to be enforced, varied or even set aside. The Family Law Act also addresses the validity and enforceability of a domestic contract.
