Getting married in California?
A prenuptial agreement in California allows couples to define how property, income, debts, and financial responsibilities will be handled if the marriage ends. Because California is a community property state, default rules can apply unless a valid prenup says otherwise.
California prenup laws are governed by the California Family Code and include specific requirements around timing, disclosure, and voluntary consent.
In short: Cal. Family Code § 1615 outlines the enforceability tests. The 7-day rule was established by statute (after the case In re Marriage of Bonds, which prompted reforms).
Key points
- Prenuptial agreements are recognized in California if they are voluntary, in writing, and signed by both partners.
- A California prenup may be unenforceable if the challenging party proves it was not signed voluntarily, or that it was unconscionable at the time of execution and signed without fair and reasonable financial disclosure or a valid written waiver of disclosure.
- California premarital agreements are governed by the California Family Code, including Sections 1610 through 1615.
- California is a community property state, and a prenup can define what remains separate property and how community property will be treated during marriage or at divorce.
Are prenups legal in California?
California’s premarital agreements are governed by the California Family Code (Cal. Fam. Code §§ 1610–1615), which adopted the UPAA with some state-specific enhancements. A prenup must be in writing and signed by both parties (no notarization required by statute, but in practice prenups are usually notarized in CA).
What makes a California prenup enforceable?
Prenuptial agreements are enforceable in California if they meet the requirements set out in the California Family Code. The court will examine whether the agreement was entered into voluntarily, whether both parties had fair financial disclosure, and whether the terms were unconscionable at the time of signing or enforcement.
California courts apply additional scrutiny when spousal support is waived or limited, especially if one party did not have independent legal counsel.
What you can—and can’t—include in a California Prenup.
California law explicitly prohibits any prenup terms that purport to affect child support or child custody – such terms are void and will be severed (Cal. Fam. Code §1612(b)). Parties can contract about property rights, business interests, estates and inheritances, and even spousal support (with the caveats above).
Simple process
Start early. California’s 7-day rule means the final draft of the prenup should be presented at least a week before signing if one or both parties are unrepresented – in practice, begin negotiations months in advance. Get attorneys if possible.
