Why a California prenup is different
A First prenup is built around the laws of California, and you, from the ground up.
Community property
If you live in California, the state already has a plan for your money. From the day you marry, most of what either of you earns, saves, or builds is owned equally by both of you. That default is called community property, and it applies automatically. A prenup is how you and your partner write a different plan together, on purpose, before any of it is theoretical. Read our full guide to California prenup laws and requirements
The seven-day signing rule
California also has the strictest signing rule in the country. At least seven calendar days have to pass between the moment the final agreement is delivered and the moment it is signed, and that rule cannot be waived, even when both partners have attorneys. The practical takeaway is simple: a California prenup works best when you start early and finish well before the wedding, not in the final week. See how California's 7-day rule works
Two ways to get a prenup in California
Self-Serve - $649
The most comprehensive prenup online, customized for you. Built with top family law attorneys and completed online by you and your partner in days, not months. Tailored to California, your finances, and your situation.
Included:
- Fully enforceable, drafted on a foundation built with family law attorneys
- Customized to California, not a generic template
- Guided questionnaire both partners complete from any device
- Full financial disclosure tools
- Covers equity, business ownership, real estate, inheritance, gifts, retirement, debts, pet custody, and more
- Online notarization included, no extra cost
- $649 flat. No retainer, no hourly bills, no surprise fees
Best if: you and your partner agree on the basics, your finances are reasonably straightforward, and $649 fits your preferred budget.
Self-Serve does not include spousal support (alimony) waivers in California, because those require each partner to have independent counsel. If you want to address spousal support, choose Lawyer Review.
Lawyer Review - $3,500
The gold standard of online prenups. Everything in Self-Serve, plus two independent attorneys, one for each of you, with drafting, revisions, and online notarization. Save thousands compared with hiring two lawyers traditionally, with no retainers and no hourly bills.
Included:
- Two independent attorneys: you pick yours, your partner picks theirs, from First's vetted California-licensed network
- Consultations and revisions included at the flat fee
- The ability to edit the underlying language with your attorney
- Spousal support provisions, which California allows only when both partners are represented
- Reserved attorney availability, so you can start today
- Online notarization included, no extra cost
- $3,500 flat. Rush service available for $750
Best if: either of you owns a business or has complex assets, either of you has been married before or has children from a prior relationship, you want each partner to have their own attorney, or you are in California and want to address spousal support.
Certain situations call for Bespoke: fully custom drafting for the most complex situations, dedicated counsel for each partner, and tailored process for the most sensitive or complicated agreements.
First vs hiring two California attorneys on your own
Key considerations
A California prenup with two independent attorneys is $3,500 total through First, with one attorney for each partner, consultations, revisions, and online notarization included. Hiring two firms separately in California, where the average lawyer bills $422 an hour and family law rates reach $800 in the largest metros, commonly runs $5,000 to $20,000 for the couple.
Hired separately, that work is billed hourly across two firms, so the final number is hard to predict before you start. First is one flat price, with no retainers and no hourly bills, and each of you gets your own independent attorney.
The hourly figures also price only the legal work. Hiring on your own means building a shortlist of local firms, calling each one, booking consults, and confirming both fee and availability against your wedding date, then running all of it again because your partner needs a different attorney. First's network is made up of local California-licensed family law attorneys who hold availability for First couples, so you each pick yours and start.

|---|---|---|
| California average, all practice areas | $422 | – |
| Largest metros, including San Jose, San Francisco and Los Angeles | $300 to $800 | – |
| Two attorneys hired separately in those metros | – | $5,000 to $20,000+ |

California prenup questions, answered
Is a prenup enforceable in California without a lawyer?
Most provisions can be enforceable without each partner hiring an attorney, as long as both partners sign a written agreement voluntarily, exchange full financial disclosure, and observe California's seven-day review period. The exception is spousal support: a waiver is only enforceable against a partner who had independent legal counsel at signing.
How much does a California prenup cost?
With First, a California prenup is a flat fee: $649 for Self-Serve, or $3,500 for Lawyer Review. A traditional two-attorney process in California commonly runs $5,000 to $20,000 or more combined, with hourly rates often between $300 and $800 in major metros.
Do I need to find a local California prenup lawyer, or can I use First?
You still get a local attorney with First. Lawyer Review at $3,500 includes an independent California-licensed family law attorney for each of you, drawn from a vetted local network that holds availability for First couples, so you get an attorney on each side without building a shortlist of local firms and calling each one. It is also the option that allows spousal support terms, which California enforces only where each partner had independent counsel. Hiring two local attorneys separately in California commonly runs $5,000 to $20,000 for the couple.
Do you do prenups in Los Angeles, San Francisco and San Diego?
Yes. First serves couples across California, including Los Angeles and Orange County, San Francisco and the Bay Area, San Jose and Santa Clara County, San Diego, and Sacramento. Lawyer Review at $3,500 includes an independent California-licensed family law attorney for each partner, and Self-Serve is $649. Both are completed online, so where in the state you live does not change the process or the price.
How much does a prenup cost in Los Angeles or San Francisco?
Family law attorneys in the largest California metros, including Los Angeles, San Francisco and San Jose, bill $300 to $800 an hour. Because each partner needs their own, hiring two separately in those markets commonly runs $5,000 to $20,000 or more for the couple. First is flat: $3,500 for Lawyer Review with both attorneys included, or $649 for Self-Serve.
What is California's 7-day rule?
California requires at least seven calendar days between the moment a partner is first given the final version of the prenup and the moment they sign it. The rule applies whether or not either partner has an attorney, and it cannot be waived. Because of it, every California prenup timeline runs backward from the wedding date, so starting early matters.
Can I do a California prenup online and have it hold up?
Yes. Completing a prenup online does not affect whether it holds up. Enforceability depends on the structure of the agreement: voluntary signing, full financial disclosure, drafting to California's rules, and independent counsel where it is required. First is built around all four.
What is the difference between Self-Serve and Lawyer Review in California?
Self-Serve at $649 is a guided, fully online prenup customized to California, best when your finances are straightforward and you are comfortable deciding together without an attorney in the room. Lawyer Review at $3,500 adds an independent attorney for each partner, the ability to edit the underlying language, and spousal support provisions, which California allows only when both partners are represented.
How long does a California prenup take with First?
Most couples complete Self-Serve in days, not months. Lawyer Review usually takes days to a few weeks, depending on complexity and how quickly both partners and both attorneys review. Build in time for California's rule that the final draft be delivered to both partners at least seven days before signing.
