What to look for in a San Francisco prenup attorney

  • Bar-licensed in California. Non-negotiable. An attorney from a neighboring state cannot represent you here.
  • Family-law focus, not generalist. California prenup procedural rules (Cal. Fam. Code §§1610–1617) are unforgiving; specialists handle them daily.
  • Active in San Francisco courts. Local court customs, scheduling, and judge familiarity matter when prenups get challenged.
  • Comfortable being one of two attorneys. Joint representation is one of the most common bases for invalidation later.
  • Flat-fee quote available. San Francisco rates are high enough that hourly billing can balloon; ask for a flat or capped fee once they\'ve scoped your situation.

California prenup rules that apply in San Francisco

  • Statute: Cal. Fam. Code §§1610–1617
  • In writing + signed: Required.
  • Notarization: Not required, but recommended.
  • Waiting period: 7 days between final draft and signing required by statute.
  • Independent counsel: Required by statute.

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.

Frequently asked questions

How much does a prenup lawyer cost in San Francisco?
In San Francisco, family-law attorney rates run $380–$750/hr. Total prenup fees range from $3,800 – $6,300 for a simple agreement to $12,500 – $25,000 for complex estates. San Francisco Bay Area attorney rates are the highest in California, often 20–30% above state average. Tech equity, IPO timing, and pre-IPO stock options make San Francisco prenups particularly business-asset-driven.
How do I find a San Francisco prenup attorney?
Three reliable paths: (1) a vetted matching service like LegalMatch that screens family-law attorneys by San Francisco-metro practice; (2) the California state bar's lawyer-referral service at https://www.calbar.ca.gov; (3) a referral from a family-law attorney you already know. Avoid general-practice attorneys — prenups have state-specific procedural rules best handled by specialists.
Do San Francisco courts apply different prenup rules than the rest of California?
No — California prenup law (Cal. Fam. Code §§1610–1617) applies uniformly across the state, including San Francisco. What varies by metro: attorney rates, court backlogs, and the typical asset mix in local prenups. The substantive enforceability standard is the same statewide.
Can I sign a prenup in San Francisco and move to another state later?
Yes, but choice-of-law clauses don't always survive a move. If you later divorce in another state, that state's courts decide whether to apply California law or local law. See the DeLorean v. DeLorean case for the textbook example. For couples with high relocation probability, drafting that satisfies multiple states' rules is the safer approach.
