Separation Agreements in Arizona: What They Cover and How They Work

Verified April 4, 2026 • 57th Legislature, 1st Regular Session

Arizona law allows married couples to create a written separation agreement that addresses property division, spousal maintenance, and child-related matters. Once the court reviews and approves the agreement, it becomes part of the final decree and is enforceable like any court judgment.

Title 25, PREMARITAL AND MARITAL AGREEMENTS

What a Separation Agreement Can Include

A separation agreement is a written contract between spouses that covers how assets, debts, maintenance, and child-related matters will be handled during and after a divorce or legal separation. Arizona law specifically encourages these agreements to promote amicable resolution. The agreement can address the disposition of any property owned by either spouse, maintenance for either party, and support, legal decision-making, and parenting time for children.

To promote amicable settlement of disputes between parties to a marriage attendant on their separation or annulment or the dissolution of their marriage, the parties may enter into a written separation agreement containing provisions for disposition of any property owned by either of them, maintenance of either of them, and support, legal decision-making and parenting time of their children.

A.R.S. § 25-317(A)

One notable provision: the agreement can include a clause stating that its maintenance terms cannot be modified. This locks in the spousal support arrangement permanently, which can be a significant planning consideration for both parties.

How the Court Reviews the Agreement

The court does not simply rubber-stamp whatever the parties agree to. It reviews the property and maintenance provisions to determine whether they are fair, considering the economic circumstances of both parties. If the court finds the agreement unfair, it can ask the parties to submit a revised version or make its own orders for property disposition and maintenance.

The terms of the separation agreement, except those providing for the support, legal decision-making and parenting time of children, are binding on the court unless it finds, after considering the economic circumstances of the parties and any other relevant evidence produced by the parties, on their own motion or on request of the court, that the separation agreement is unfair.

A.R.S. § 25-317(B)

Once approved, the agreement's terms are set forth in the decree and enforceable by all remedies available for a court judgment, including contempt. Property and maintenance terms generally cannot be modified after entry of the decree, making the initial negotiation critically important for both spouses' long-term financial planning.

25-317. Separation agreement; effect A. To promote amicable settlement of disputes between parties to a marriage attendant on their separation or annulment or the dissolution of their marriage, the parties may enter into a written separation agreement containing provisions for disposition of any property owned by either of them, maintenance of either of them, and support, legal decision-making and parenting time of their children. A separation agreement may provide that its maintenance terms shall not be modified. B. In a proceeding for dissolution of marriage, for annulment or for legal separation, the terms of the separation agreement, except those providing for the support, legal decision-making and parenting time of children, are binding on the court unless it finds, after considering the economic circumstances of the parties and any other relevant evidence produced by the parties, on their own motion or on request of the court, that the separation agreement is unfair. C. If the court finds the separation agreement unfair as to disposition of property or maintenance, it may request the parties to submit a revised separation agreement or may make orders for the disposition of property or maintenance. D. If the court finds that the separation agreement is not unfair as to disposition of property or maintenance and that it is reasonable as to support, legal decision-making and parenting time of children, the separation agreement shall be set forth or incorporated by reference in the decree of dissolution, annulment or legal separation and the parties shall be ordered to perform them. E. Terms of the agreement set forth or incorporated by reference in the decree are enforceable by all remedies available for enforcement of a judgment, including contempt. F. Except for terms concerning the maintenance of either party and the support, legal decision-making or parenting time of children, entry of the decree shall thereafter preclude the modification of the terms of the decree and the property settlement agreement, if any, set forth or incorporated by reference. G. Notwithstanding subsection F of this section, entry of a decree that sets forth or incorporates by reference a separation agreement that provides that its maintenance terms shall not be modified prevents the court from exercising jurisdiction to modify the decree and the separation agreement regarding maintenance, including a decree entered before July 20, 1996.

How does estate planning work for blended families and second marriages?

Blended families need intentional planning because default legal rules often do not match your wishes. A trust can provide for a surviving spouse while protecting your children from a previous marriage.

How does divorce affect my estate plan in Arizona?

Arizona law (A.R.S. 14-2804) revokes many estate plan provisions favoring a former spouse, but ERISA-governed retirement plans and some other assets require manual beneficiary updates. A full estate plan review after divorce is essential.
