Arizona Prenuptial Agreement Laws: Requirements and Enforceability
Independently fact-checked against primary sources (last audited October 8, 2026). · 10 primary sources cited on this page. How we verify our legal content
Arizona prenups are governed by A.R.S. §§ 25-201 to 25-205, in Title 25, chapter 2, article 1. A premarital agreement must be in writing and signed by both parties, and under A.R.S. 25-202(C) a court will not enforce it if the challenging spouse proves it was signed involuntarily, or that it was unconscionable when signed and the required financial disclosure was missing.

Jurisdiction scope: This article covers premarital and postnuptial agreements under Arizona Revised Statutes Title 25, chapter 2, article 1 (A.R.S. 25-201 to 25-205 and 25-202.01), with a note on community property under 25-211. It does not cover covenant marriage, Arizona case law beyond the decision noted below, or other states' law. It is general information, not drafting guidance.
Which law governs prenups in Arizona
Arizona's rules for premarital agreements sit in one article of Title 25: A.R.S. 25-201, 25-202, 25-202.01, 25-203, 25-204 and 25-205. The central section is 25-202, which sets the formalities and the tests for enforcement. A 2026 law amended the article and added 25-202.01 for postnuptial agreements, covered below.
Formal requirements for an Arizona prenup
A.R.S. 25-202(A) provides: "A premarital agreement must be in writing and signed by both parties. The agreement is enforceable without consideration." Under 25-202(B), "The agreement becomes effective on marriage of the parties."
The six sections of the article contain no notarization, witness or filing requirement, no requirement that each party have a lawyer, and no waiting period between receiving and signing the agreement.
When an Arizona prenup is not enforceable
A.R.S. 25-202(C) puts the burden on the person resisting the agreement. It is not enforceable if that person proves either of two things:
| Ground | What the statute requires | Cite |
|---|---|---|
| Involuntary | "The person did not execute the agreement voluntarily." | 25-202(C)(1) |
| Unconscionable plus no disclosure | The agreement was unconscionable when executed, and before signing the person (a) was not given fair and reasonable disclosure of the other party's property or financial obligations, (b) did not voluntarily and expressly waive, in writing, any right to further disclosure, and (c) did not have, or reasonably could not have had, adequate knowledge of the other party's property or financial obligations | 25-202(C)(2) |
The second ground is conjunctive. Unconscionability alone is not enough under the statute; the disclosure failures in (a), (b) and (c) must also be shown. A party can waive further disclosure, but only voluntarily, expressly and in writing.
Who decides. Under 25-202(E), "An issue of unconscionability of a premarital agreement shall be decided by the court as a matter of law."
Timing of the unconscionability review. In Meek v. Meek, No. 1 CA-CV 23-0010 FC (Ariz. App. 2023), at paragraph 35, the Arizona Court of Appeals, citing In re Marriage of Pownall, 197 Ariz. 577 (App. 2000), described courts as reviewing premarital agreements for unconscionability as of when they were entered.
Spousal support waivers
A prenup may modify or eliminate spousal support (A.R.S. 25-203(A)), with one statutory safety valve. Under 25-202(D), if that provision would make a party eligible for public assistance at separation or dissolution, "a court, notwithstanding the terms of the agreement, may require the other party to provide support to the extent necessary to avoid that eligibility." For how maintenance works without an agreement, see Arizona alimony laws.
What an Arizona prenup can and cannot cover
Permitted subjects. A.R.S. 25-203(A) lets the parties contract about property rights, how property is disposed of at separation, dissolution or death, modification or elimination of spousal support, wills and trusts, life insurance proceeds, choice of law, and other matters "not in violation of public policy or a statute imposing a criminal penalty."
Child support. Under 25-203(B), "The right of a child to support may not be adversely affected by a premarital or postnuptial agreement." This page does not cover how Arizona courts treat terms about legal decision-making or parenting time.
If the marriage is void. Under 25-202(F), an agreement that would otherwise have been a premarital agreement is enforceable, if the marriage turns out to be void, only to the extent necessary to avoid an inequitable result.
Changing or revoking a prenup
A.R.S. 25-204 provides: "After marriage, a premarital or postnuptial agreement may be amended or revoked only by a written agreement signed by the parties." The amendment or revocation is enforceable without consideration.
Time limits. Under 25-205, "A statute of limitations applicable to an action asserting a claim for relief under a premarital or postnuptial agreement is tolled during the marriage of the parties to the agreement." Laches and estoppel remain available as defenses.
Postnuptial agreements in Arizona
HB 2861 (Laws 2026, chapter 26), signed April 7, 2026, added A.R.S. 25-202.01 on postnuptial agreements and amended 25-201, 25-203, 25-204 and 25-205 to refer to them. The Arizona Legislature's statute site displayed the new section when this page was verified on 2026-10-08. HB 2861 has no emergency clause, so it took effect on the session's general effective date, September 12, 2026. The act does not say whether 25-202.01 applies to postnuptial agreements signed before that date; a lawyer licensed in Arizona can advise on an older agreement.
As the section reads, a postnuptial agreement must be in writing and signed by both spouses and takes effect when executed. It is not enforceable if the challenger proves any of the following:
- the agreement was not free from the taint of fraud, coercion or undue influence;
- the person did not act with full knowledge of the property involved and their rights in it;
- the agreement is not fair and equitable; or
- the agreement does not reflect the spouses' mutual intent to divide or delineate their property interests.
The burden is higher than for a prenup: "The burden is on the party seeking to challenge the postnuptial agreement to prove by clear and convincing evidence that the postnuptial agreement is not enforceable." The grounds also differ from the premarital test in 25-202(C), so a postnup and a prenup are judged under different standards.
How Arizona treats property without a prenup
Arizona is a community property state. Under A.R.S. 25-211(A), "All property acquired by either husband or wife during the marriage is the community property of the husband and wife," except property acquired by gift, devise or descent and property acquired after service of a divorce, legal separation or annulment petition that results in a decree. See Arizona divorce laws for how community property is divided.
Who drafts an Arizona prenup
Prenups are drafted and reviewed by lawyers licensed in Arizona. The statute does not require each party to have a lawyer, but whether an agreement was signed voluntarily and with adequate disclosure decides whether it holds up under 25-202(C).

Frequently Asked Questions
Are prenups enforceable in Arizona?
Yes, if in writing and signed by both parties. A court will not enforce one if the challenger proves involuntary signing, or unconscionability at signing plus the disclosure failures listed in A.R.S. 25-202(C)(2).
Does a prenup need to be notarized in Arizona?
A.R.S. 25-202(A) requires a writing signed by both parties; the article's sections contain no notarization, witness or filing requirement.
Can you waive financial disclosure in an Arizona prenup?
Yes, but only voluntarily and expressly in writing. The waiver is one of the three disclosure conditions in A.R.S. 25-202(C)(2)(b).
Can an Arizona prenup eliminate spousal maintenance?
A.R.S. 25-203(A) allows terms modifying or eliminating spousal support, but if that would leave a spouse eligible for public assistance, a court may require support to the extent needed to avoid it (A.R.S. 25-202(D)).
Can a prenup limit child support in Arizona?
No. A child's right to support may not be adversely affected by a premarital or postnuptial agreement (A.R.S. 25-203(B)).
Is Arizona a community property state for prenups?
Yes. Property acquired during marriage is community property unless an exception applies (A.R.S. 25-211(A)), and a prenup may set different property rights (A.R.S. 25-203(A)).
