Alaska's package uses Brooks v. Brooks as a leading Supreme Court decision on voluntariness, disclosure, fairness, and enforcement.Brooks v. Brooks, 733 P.2d 1044 (Alaska 1987)
Title 25 supplies the statutory background for marriage, divorce, property, support, and children, so mandatory rules must be checked separately from the contract framework.Alaska Stat. tit. 25, including § 25.24.160
Formation and lifecycle
An agreement made upon consideration of marriage, other than mutual promises to marry, is unenforceable against the party charged unless the agreement or a note or memorandum is written and subscribed by that party or an authorized agent.
Alaska Stat. § 09.25.010(a)(5)The separate Community Property Act instrument must be in a written document signed by both spouses, classify some or all property as community property, and begin with the statute's capital-letter warning; it is enforceable without consideration.
Alaska Stat. § 34.77.090(a)–(b)People intending to marry may execute a community property agreement as if married, but it becomes effective only when they marry; the chapter's determination date is the latest of marriage, the instrument's effective date, or May 23, 1998.
Alaska Stat. § 34.77.090(f); § 34.77.900(7)A community property agreement may be amended or revoked only as the agreement itself permits or by a later community property agreement; the statute also contains a qualified surviving-spouse rule for nonprobate dispositions.
Alaska Stat. § 34.77.090(e)For an ordinary premarital agreement, the contemplated marriage supplies consideration; adequacy of the bargain is addressed through fairness rather than by inventing an unstated promise.
Andrew B. v. Abbie B., 494 P.3d 522 (Alaska 2021)Alaska has no general UPAA amendment section for ordinary prenups; Compton distinguishes asset-specific transmutation evidence from formal modification or waiver of the agreement.
Compton v. Compton, 902 P.2d 805 (Alaska 1995)What the agreement addresses
Title 25 supplies mandatory dissolution, property, support, custody, and child-related rules that operate alongside any premarital agreement.
Alaska Stat. tit. 25, including § 25.24.160A qualifying community property agreement may address property rights, management, disposition, estate planning, nonprobate transfers, governing law, and other lawful property matters, but may not adversely affect a child's right to support.
Alaska Stat. § 34.77.090(c)–(d)A community property agreement may not adversely affect a child's right to support.
Alaska Stat. § 34.77.090(c)A surviving spouse may waive elective-share, homestead, exempt-property, and family-allowance rights before or after marriage in a signed writing; the statute preserves voluntariness and execution-time unconscionability plus disclosure, written-waiver, and knowledge safeguards.
Alaska Stat. § 13.12.213Ordinary contract interpretation applies, but a court may not add a benefit, fund, or promise the parties did not make merely to repair a one-sided agreement.
Andrew B. v. Abbie B., 494 P.3d 522 (Alaska 2021)A valid prenup is persuasive but not conclusive evidence of intent to keep property separate; a court may examine the parties' treatment of particular assets and find transmutation while the agreement remains valid.
Compton v. Compton, 902 P.2d 805 (Alaska 1995)Kilkenny confirms the court first asks whether execution was voluntary, then whether the agreement was unconscionable when executed or later circumstances make enforcement unfair and unreasonable; it expressly notes Alaska has not adopted UPMAA.
Kilkenny v. Kilkenny, No. S-18602, Opinion No. 7787 (Alaska Sept. 19, 2025)A court may selectively strike terms made unfair or unreasonable by material changed circumstances without voiding the entire agreement, but it may not add new promises and must explain term-by-term choices sufficiently for appellate review.
Kilkenny v. Kilkenny, No. S-18602, Opinion No. 7787 (Alaska Sept. 19, 2025)Kilkenny holds that domestic violence and coercive financial control during marriage may be material changed circumstances making particular attorney-fee, support, or property-remedy restrictions unfair or unreasonable.
Kilkenny v. Kilkenny, No. S-18602, Opinion No. 7787 (Alaska Sept. 19, 2025)No private child-support waiver is valid without judicial scrutiny under Civil Rule 90.3, and parents may not contract around the child's right or the court's guideline and modification duties.
Nix v. Nix, 855 P.2d 1332 (Alaska 1993); Alaska Civil Rule 90.3Trial courts, not parents, are the ultimate custody decision makers and are not bound by private agreements; current best-interests law controls.
Dirkes v. Dirkes, 502 P.3d 1115 (Alaska 2022) (Opinion No. 7575)Process evidence
Section 34.77.090 supplies different enforcement formulations for agreements executed during marriage and before marriage, addressing voluntariness, execution-time unconscionability, disclosure, written waiver, and financial notice; the court decides unconscionability as a matter of law.
Alaska Stat. § 34.77.090(g)–(i)Brooks recognizes legally procured and ostensibly fair premarital agreements and asks about fraud, duress, mistake, misrepresentation or material nondisclosure, execution-time unconscionability, and changed circumstances making enforcement unfair or unreasonable.
Brooks v. Brooks, 733 P.2d 1044 (Alaska 1987)Material nondisclosure, misrepresentation, fraud, mistake, or duress can defeat enforcement under Brooks; the actual schedules, debts, values, and knowledge record must be preserved.
Brooks v. Brooks, 733 P.2d 1044 (Alaska 1987)Andrew requires a combined, fact-specific evaluation of time to review, ability and opportunity to consult independent counsel meaningfully, and ability to understand the agreement; no single factor is dispositive and ordinary duress is not the exclusive test.
Andrew B. v. Abbie B., 494 P.3d 522 (Alaska 2021)Alaska has no fixed statutory waiting-period safe harbor for an ordinary prenup; Andrew makes the actual time to receive, review, understand, and respond to the agreement essential to voluntariness.
Andrew B. v. Abbie B., 494 P.3d 522 (Alaska 2021)The focus is not merely whether separate counsel appeared, but whether the party had the ability and opportunity to consult independent counsel in a meaningful way.

A party disclosed ownership of remote land but gave no appraisal or debt information. Brooks makes the quality of disclosure and the other party's knowledge fact-specific questions.Brooks v. Brooks, 733 P.2d 1044 (Alaska 1987)
What information was needed for adequate financial understanding under current Alaska law?
