Hardship After Career Loss
Arthur Abrams and Amber Alonzo signed an antenuptial agreement waiving spousal support. Five years later Amber lost her high-paying job due to industry changes and faced public assistance eligibility. The court refused to enforce the waiver term because enforcement would cause substantial hardship from a material change in circumstances after signing.
Property Apportionment on Divorce
Adam Anderson and Audrey Ashton entered an antenuptial agreement before marriage. Upon dissolution the court considered the agreement when equitably apportioning property acquired during the marriage without regard to marital misconduct and factoring in each spouse's contributions and needs.

Cohabitation Contract Analogy
Albert Allen and Andre Antoine lived together under an oral agreement allocating earnings and property. After separation a court enforced the agreement because it was not inseparably based on sexual services, treating it with the same contractual force given to antenuptial agreements between married couples.
Marvin v. Marvin557 P.2d 106 (Cal. 1976)
Frozen Embryo Disposition
A.Z. and B.Z. signed an antenuptial-style agreement addressing disposition of frozen embryos upon divorce. The court declined to enforce the agreement's terms because they implicated public policy concerns over procreation that could not be resolved by contract alone.
A.Z. v. B.Z.431 Mass. 150, 725 N.E.2d 1051 (2000)
Trust Assets and Elective Share
Arthur Abrams placed assets in an inter vivos trust and later married. His surviving spouse claimed an elective share. The court held that the antenuptial agreement did not automatically defeat the claim because the trust assets remained reachable under principles protecting spousal statutory rights.

…the subjective contemplation of the parties is uncertain and unworkable; such a test, we stated, "might invalidate virtually all antenuptial agreements on the ground that the parties contemplated dissolution ... but it provides no principled basis for determining which antenuptial agreements offend public policy and which do not."
