A separation agreement is a written contract between spouses resolving financial and parenting issues either during a legal separation or as the basis for a later dissolution decree. It may address property division, debt allocation, spousal maintenance, child support, legal decision making, and parenting time.

In Arizona a separation agreement entered in a legal separation proceeding can later be incorporated into a dissolution decree if the parties proceed to divorce.

A separation agreement is a contract. Its enforceability depends on whether it was entered voluntarily, with adequate disclosure, and without unconscionable terms.
