Prenuptial Agreement Cost in California
Last updated 5 min read
A prenuptial agreement in California typically costs $3,000 – $5,000 for a simple agreement and up to $10,000 – $20,000 for complex estates. California prenup costs depend on attorney rates, how complex your finances are, and whether both spouses retain their own lawyer. This page isn't legal advice — it's a plain-English summary of how a prenup in California works, what it costs, and what the state requires.
Cost breakdown
| Complexity | Typical cost | Who this fits |
|---|---|---|
| Simple | $3,000 – $5,000 | W-2 income, no business, no kids from prior relationships |
| Moderate | $5,000 – $10,000 | Real estate, retirement accounts, modest separate property |
| Complex | $10,000 – $20,000 | Business interests, multi-state property, expected inheritance |
Average attorney rate in California: $300–$600/hr. Both spouses hiring separate attorneys typically adds 50–75% to the total bill.
What California law requires
- In writing: Yes — required.
- Notarization: Not required, but recommended for evidentiary purposes.
- Independent counsel: Required by statute.
- Waiting period: 7 days between final draft and signing required by statute.
- Community property state: Yes — without a prenup, property acquired during marriage is presumptively split equally.
The controlling statute is Cal. Fam. Code §§1610–1617 — read the full text on the California legislature site.
California has the strictest procedural framework in the country. The 7-day rule in Cal. Fam. Code §1615(c)(2) requires at least seven calendar days between presenting the final agreement and signing it. Either both parties have independent counsel, or the unrepresented party signs an express written waiver after being warned in writing of the terms and effect. Disclosure must be specific and complete.
A notable California case
In re Marriage of Bonds, 24 Cal.4th 1 (2000). California Supreme Court upheld a prenup signed the day before the wedding without independent counsel — and the resulting public outcry pushed the Legislature to enact §1615(c), the modern 7-day rule and independent-counsel requirement.
Timeline
Start the conversation at least 90 days before the wedding. The statutory minimum between final draft and signing is 7 days; aim for 30+.
