California Code, Family Code - FAM § 2251

(1) Declare the party or parties, who believed in good faith that the marriage was valid, to have the status of a putative spouse.

(2) If the division of property is in issue, divide, in accordance with Division 7 (commencing with Section 2500), that property acquired during the union that would have been community property or quasi-community property if the union had not been void or voidable, only upon request of a party who is declared a putative spouse under paragraph (1). This property is known as “quasi-marital property.”
