(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, must join in executing any instrument by which that community real property or any interest therein is leased for a longer period than one year, or is sold, conveyed, or encumbered.

(b) Nothing in this section shall be construed to apply to a lease, mortgage, conveyance, or transfer of real property or of any interest in real property between husband and wife.

(c) Notwithstanding subdivision (b): (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) No action to avoid any instrument mentioned in this section, affecting any property standing of record in the name of either spouse alone, executed by the spouse alone, shall 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) Nothing in this section precludes either spouse from encumbering his or her 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.
