California Code, Family Code - FAM § 761

(a) Unless the trust instrument or the instrument of transfer expressly provides otherwise, community property that is transferred in trust remains community property during the marriage, regardless of the identity of the trustee, if the trust, originally or as amended before or after the transfer, provides that the trust is revocable as to that property during the marriage and the power, if any, to modify the trust as to the rights and interests in that property during the marriage may be exercised only with the joinder or consent of both spouses.

(b) Unless the trust instrument expressly provides otherwise, a power to revoke as to community property may be exercised by either spouse acting alone. Community property, including any income or appreciation, that is distributed or withdrawn from a trust by revocation, power of withdrawal, or otherwise, remains community property unless there is a valid transmutation of the property at the time of distribution or withdrawal.

(c) The trustee may convey and otherwise manage and control the trust property in accordance with the provisions of the trust without the joinder or consent of either spouse unless the trust expressly requires the joinder or consent of one or both spouses.

(d) This section applies to a transfer made before, on, or after July 1, 1987.

(e) Nothing in this section affects the community character of property that is transferred before, on, or after July 1, 1987, in any manner or to a trust other than described in this section.
