What a traditional prenup costs in California
The traditional way to get a prenup in California involves hiring two separate family law attorneys — one for each partner. Each attorney typically charges $2,500–$10,000, depending on the complexity of your financial situation, the attorney's experience, and your location within the state. That puts the combined cost at $5,000–$20,000 for a standard prenuptial agreement.
These costs break down into several components: initial consultation ($250–$500 per attorney), drafting the agreement ($1,500–$5,000), negotiation and revisions ($500–$3,000), and the final signing ceremony. In California's community property system, additional complexity around characterizing separate vs. community assets can push costs higher.
What drives the cost up
- **Complex asset portfolios** — Business interests, real estate holdings, stock options, and retirement accounts all require more detailed drafting
- **Spousal support provisions** — Addressing alimony waivers or modifications adds legal complexity, especially in states with specific requirements
- **Multiple rounds of negotiation** — If partners disagree on terms, attorney hours accumulate quickly
- **High-net-worth situations** — More assets means more schedules, more disclosure, and more attorney time
- **California-specific requirements** — Notarization costs, the 7-day waiting period, and compliance with Cal. Fam. Code § 1610-1617 all factor into the total
How Clause reduces the cost
Clause is a legal technology platform that generates state-specific prenuptial agreements at a fraction of the traditional cost. The platform was built with licensed family law attorneys and generates documents that comply with California law — including Cal. Fam. Code § 1610-1617 requirements, community property rules, and all signing formalities.
Clause pricing
- **Essential Plan — $549** — Core agreement covering property division, debt allocation, spousal support, financial disclosure, and partner review. One document generation included.
- **Comprehensive Plan — $699** — Everything in Essential plus optional clauses (pets, sunset, marital residence, insurance, reproductive material, digital assets, dispute resolution), plain-language agreement analysis, unlimited revisions, AI reference translation (60+ languages), live document preview, and online notarization included.
- **Attorney Review — $699 per partner** — A licensed family law attorney in your state independently reviews the completed document for legal soundness and state compliance.
- **Online Notarization — $50** — A licensed notary witnesses your signatures via secure video call. Included free with Comprehensive.
Even with attorney review for both partners added on, the total cost through Clause ($549–$2,097) is significantly less than the traditional route ($5,000–$20,000). The difference is that Clause handles the document generation — the most time-intensive part of the traditional process — automatically.
Does California require attorney review?
California requires independent legal counsel for the party waiving spousal support. If your prenup doesn't modify spousal support, attorney review is not legally required — but it's strongly recommended for enforceability. Courts look favorably on agreements where both parties had their own counsel.
The real cost of not having a prenup
Without a prenup, California's default community property rules apply. In a community property state, that means a 50/50 split of everything earned during the marriage — including business appreciation, retirement contributions, and investment gains. If you started a business before marriage but it grew during the marriage, half that growth could be considered community property. A $549–$699 prenup is insurance against that outcome.
