Prob. Code, § 3051

(a) Subject to Section 3071, the right of a spouse to manage and control community property, including the right to dispose of community property, is not affected by the lack or alleged lack of legal capacity of the other spouse.

(b) Except as provided in subdivision (c), if one spouse has legal capacity and the other has a conservator:

(1) The spouse who has legal capacity has the exclusive management and control of the community property including, subject to Section 3071, the exclusive power to dispose of the community property.

(2) The community property is not part of the conservatorship estate.

(c) If one spouse has legal capacity and the other has a conservator, the spouse having legal capacity may consent, by a writing filed in the proceeding, that all or part of the community property be included in and, subject to Section 3071, be managed, controlled, and disposed of as a part of the conservatorship estate.

(d) Except as provided in subdivision (e), if both spouses have conservators, an undivided one-half interest in the community property shall be included in and, subject to Section 3071, be managed, controlled, and disposed of as a part of the conservatorship estate of each spouse.

(e) If both spouses have conservators, when authorized by order of the court in which any of the conservatorship proceedings is pending, the conservators may agree in writing that all or specific parts of the community property shall be included in the conservatorship estate of one or the other of the spouses and, subject to Section 3071, be managed, controlled, and disposed of as a part of the conservatorship estate of that spouse.
