California Premarital Asset Laws

California is a community property state — most assets and debts acquired during marriage are owned equally by both spouses.

Overview

California is a community property state, which means that nearly all assets and debts acquired by either spouse during the marriage are considered jointly owned — a 50/50 split regardless of who earned or spent the money.

What Counts as Community Property?

  • Wages and salaries earned during marriage
  • Property purchased with marital income
  • Debts incurred during the marriage (by either spouse)

What Stays Separate?

  • Assets owned before the marriage
  • Gifts and inheritances received by one spouse (even during marriage)
  • Property acquired after permanent separation
  • Assets explicitly kept separate per a valid prenuptial or postnuptial agreement

Prenuptial Agreements in California

California enforces prenuptial agreements under the California Uniform Premarital Agreement Act (Family Code § 1600–1617). For a prenup to be valid:

  1. It must be in writing and signed by both parties
  2. There must be no duress — both parties must sign voluntarily
  3. Each party should have independent legal representation (or waive it in writing)
  4. A 7-day waiting period is required between presentation and signing
  5. Full financial disclosure is required from both parties

Key Considerations

  • California’s community property rules are some of the strongest in the nation
  • Even commingled accounts (mixing separate and marital funds) can complicate tracing
  • A prenup can designate future earnings as separate property
