Cal. FAM § 1102

(a) Except as provided in Sections 761 and 1103, either spouse has the management and control of the community real property, whether acquired prior to, or on or after January 1, 1975, but both spouses, either personally or by a duly authorized agent, are required to join in executing an instrument by which that community real property or an interest therein is leased for a longer period than one year, or is sold, conveyed, or encumbered.

(b) This section does not apply to a lease, mortgage, conveyance, or transfer of real property, or of an interest in real property, between spouses.

(c) Notwithstanding subdivision (b), both of the following shall apply:

(1) The sole lease, contract, mortgage, or deed of the husband, holding the record title to community real property, to a lessee, purchaser, or encumbrancer, in good faith without knowledge of the marriage relation, shall be presumed to be valid if executed prior to January 1, 1975.

(2) The sole lease, contract, mortgage, or deed of either spouse, holding the record title to community real property to a lessee, purchaser, or encumbrancer, in good faith without knowledge of the marriage relation, shall be presumed to be valid if executed on or after January 1, 1975.

(d) An action to avoid an instrument mentioned in this section, affecting any property standing of record in the name of either spouse alone, executed by the spouse alone, shall not be commenced after the expiration of one year from the filing for record of that instrument in the recorder’s office in the county in which the land is situated.

(e) This section does not preclude either spouse from encumbering that spouse’s interest in community real property, as provided in Section 2033, to pay reasonable attorney’s fees in order to retain or maintain legal counsel in a proceeding for dissolution of marriage, for nullity of marriage, or for legal separation of the parties.
