Prenuptial Agreement in
California

Under California Family Code § 721, if a party is not represented by independent legal counsel, the final agreement must be delivered to that party at least seven calendar days before signing. This waiting period ensures there is time for meaningful review.

California's community property system treats most assets and income earned during marriage as jointly owned. A prenup can override these defaults for designated assets, keeping them as the separate property of one spouse.

Yes, but with limits. A California court may decline to enforce a spousal support waiver if it is unconscionable at the time of enforcement, and the waiving spouse must have been independently represented at the time of signing for the waiver to be most effective.

Independent counsel is not required, but it is strongly encouraged. If a party is unrepresented, they must sign a separate declaration stating they were advised of their right to counsel and voluntarily waived it.

A California prenup can be invalidated if it was signed under duress, if there was inadequate financial disclosure, if the seven-day waiting period was not observed for unrepresented parties, or if the terms were unconscionable when signed.

Family Code § 1615(c)(2) requires at least seven calendar days between the day a partner is first presented with the final prenuptial agreement and the day they sign it. The waiting period gives each person time to read the document and consult a lawyer if they choose. Practically, this means finalizing your prenup at least a week — ideally a month or more — before the wedding. Signing earlier than day seven risks the whole agreement.

No — you can create your own California prenup. If you sign without a lawyer, the law simply requires that you expressly waive independent counsel in a separate signed document and receive a written plain-language explanation of the terms. One exception is provision-specific: a waiver of spousal support is only enforceable if the waiving partner actually had independent counsel at signing (Fam. Code § 1612(c)). Everything else can be done without attorneys.

California has the country's priciest prenups: attorney-drafted agreements typically run $3,000 to $8,000, and in Los Angeles, San Francisco, or Silicon Valley — especially with startup equity involved — bills of $10,000+ for two sets of counsel are common. Creating your California prenup online costs a flat $349, built around the state's 7-day rule and disclosure standards. Optional review by a local attorney adds a few hundred dollars and is required only if you want an enforceable spousal-support waiver.

With prenups.ai, you can have a draft prenuptial agreement in under 20 minutes. Traditional attorney routes in California typically take 2–6 weeks due to scheduling, drafting, negotiation, and review. If a party does not have independent legal counsel, they must be given at least 7 calendar days between first receiving the final agreement and signing it. This is a critical requirement. We recommend starting the process at least 2–3 months before your wedding to allow time for review and any revisions.

Yes. California does not require you to have an attorney to create a valid prenuptial agreement. However, having each party consult with independent legal counsel significantly strengthens enforceability. Many couples use prenups.ai to create the initial draft and then have it reviewed by attorneys, which is much more affordable than starting from scratch.

Without a prenup, California's default community property rules apply. California is a community property state. All property acquired during the marriage is generally owned 50/50 by both spouses, regardless of who earned it. A prenup lets you define your own terms instead of leaving these decisions to state law or a judge's discretion.
