Examples of unfair terms in a prenuptial agreement

On Behalf of | Aug 21, 2025 | Family Law

Prenuptial agreements help couples determine how to handle their property and finances in the event of a divorce or separation. While these contracts are valid in California, not every term is enforceable. Courts may strike out provisions that are unfair or against public policy.

Here are some crucial points to remember

What can be included in a prenup?

California law allows couples to use prenups to clarify how property will be divided in divorce. Terms often cover separate and community property, debt responsibility and inheritance rights. A prenup can also outline how spouses will manage financial matters during marriage. These agreements must be in writing, signed voluntarily and include full financial disclosure.

What terms might be considered unfair?

Certain provisions are often viewed as unfair or invalid. For example, a prenup cannot limit child support or custody rights, as these decisions must be made in the best interests of the child. Terms that encourage divorce, such as financial rewards for ending the marriage, are also unenforceable. If one spouse hides assets, pressures the other to sign or does not provide a reasonable chance to review the agreement, the entire contract can be challenged.

Unfair terms may also include extreme waivers of spousal support. Under California law, a spousal support waiver is unenforceable if the spouse did not have independent legal guidance before signing or if enforcing it would be unconscionable at the time of divorce.

Courts in California have the authority to strike out unfair or unlawful provisions while still enforcing the valid parts of a prenup. If the agreement as a whole is deemed unfair, it may be set aside entirely. This ensures that prenuptial agreements protect both parties without undermining legal rights or public policy.
