California is a community property state
California is a community property state — without a prenup, all assets earned during marriage are split 50/50. A prenup is especially important in California — without one, all income and assets earned during the marriage are automatically split 50/50 regardless of who earned them.
Prenup Cost in California — Full Breakdown
| Option | Cost in California | Best for |
|---|---|---|
| Two separate attorneys (one per spouse) | $2,500–$10,000 | Complex assets, business ownership, high net worth, or prior marriages |
| One attorney drafts; second reviews | $1,375–$5,500 | Moderate assets; one party takes the lead on drafting |
| Online platform (HelloPrenup) | $599/couple | Straightforward finances, combined assets under $500K, no children from prior relationships |
| DIY template (not recommended) | $0–$99 | Not recommended — enforceability risk without attorney review |
California attorneys typically bill $300–$600/hour for family law matters. A standard prenup requires 8–20 hours of attorney time per side — covering the initial consultation, drafting, negotiation, revisions, and signing.

Key enforcement note
California has some of the strictest prenup requirements in the country. The 7-day rule is strictly enforced — signing immediately before the wedding creates a presumption of duress.
What Makes a California Prenup More Expensive
Attorney cost varies within the $2,500–$10,000 range based on complexity:
Business ownership
Valuing and protecting a business interest in a California prenup adds significant complexity — potentially requiring a business valuation expert and more detailed drafting provisions.
Adds $1,000–$3,000+
Real estate
If either party owns real estate in multiple states, each property's treatment must be addressed under the relevant state's laws.
Adds $500–$2,000
Prior marriage or children
Protecting children from a prior relationship requires careful estate planning integration — often a separate process running alongside the prenup.
Adds $500–$2,000
Negotiation and revisions
If the parties disagree on terms and require multiple rounds of revision, attorney fees increase proportionally. The simple estimates assume 2–3 drafts.
Variable — $300–$500/round
Attorney location
Attorneys in California's major metros (especially LA and San Francisco) typically bill 120–300 more per hour than suburban or rural attorneys.
