Hardship After Career Loss
Pearl Porter and Phuong Pham signed a prenuptial agreement before their wedding that eliminated all spousal support. Five years later Phuong lost her high-paying job and developed a serious illness that prevented her from working. When the marriage ended, the court refused to enforce the support waiver because enforcement would cause Phuong substantial hardship from a material change in circumstances arising after signing.
Property Division at Divorce
Phoebe Park brought substantial separate real-estate holdings into her marriage with Parker Phillips. Their prenuptial agreement addressed only support and left property division to state law. At divorce the court treated the agreement as one factor in its equitable apportionment of all assets acquired during the marriage, without regard to marital misconduct.

Cohabitation Contract Enforced

After separation Piper sought to enforce their written agreement dividing the home and other assets. The court upheld the agreement because it rested on valid consideration independent of any sexual relationship and did not violate public policy.

Preembryo Disposition Agreement
Parker Phillips and Piper Patel signed a prenuptial agreement that included a clause directing disposition of frozen preembryos in the event of divorce. After the marriage ended, one party sought to use the preembryos over the other's objection. The court refused to enforce the clause because it would compel parenthood against the contemporaneous wishes of one donor.

Common questions
Frequently Asked
5
Does a prenuptial agreement require consideration to be enforceable?+
No. A written prenuptial agreement signed by both parties is enforceable without consideration under modern statutes governing waivers of spousal rights.
Supporting sources
When is a prenuptial agreement unenforceable for lack of financial disclosure?+
A prenuptial agreement is unenforceable if the party against whom enforcement is sought did not receive a reasonably accurate description of the other party's property, liabilities, and income, or expressly waive further disclosure, or already possess adequate knowledge of that information.
Supporting sources
What constitutes duress that renders a prenuptial agreement unenforceable?+
Duress exists when one party conditions the wedding or essential benefits on immediate signature and the timing and pressure overcome the other party's free will, leaving no reasonable alternative.
Supporting sources
Must a party have independent counsel for a prenuptial agreement to be valid?+
Access to independent legal representation is required unless the agreement contains the statutory conspicuous notice of waiver or a plain-language explanation of the rights modified. Access means a reasonable opportunity to decide on counsel, locate one, obtain advice, and consider it.
Supporting sources
Can a prenuptial agreement waive a surviving spouse's elective share and allowances?+
Yes. A written prenuptial agreement signed by the surviving spouse can affirm, modify, or waive the elective share, homestead allowance, exempt property, and family allowance, and such an agreement is enforceable without consideration.
