Cal. Probate Code § 3140

(a) A conservator served pursuant to this article shall, and the Director of State Hospitals or the Director of Developmental Services given notice pursuant to Section 1461 may, appear at the hearing and represent a spouse alleged to lack legal capacity for the proposed transaction. (b) The court may, in its discretion and if necessary, appoint an investigator to review the proposed transaction and report to the court regarding its advisability. (c) If the court determines that a spouse alleged to lack legal capacity has not competently retained independent counsel, the court may in its discretion appoint the public guardian, public administrator, or a guardian ad litem to represent the interests of the spouse. (d) (1) If a spouse alleged to lack legal capacity is unable to retain legal counsel, upon request of the spouse, the court shall appoint the public defender or private counsel under Section 1471 to represent the spouse and, if that appointment is made, Section 1472 applies. (2) If the petition proposes a transfer of substantial assets to the petitioner from the other spouse and the court determines that the spouse has not competently retained independent counsel for the proceeding, the court may, in its discretion, appoint counsel for the other spouse if the court determines that appointment would be helpful to resolve the matter or necessary to protect the interests of the other spouse. (e) Except as provided in paragraph (1) of subdivision (d), the court may fix a reasonable fee, to be paid out of the proceeds of the transaction or otherwise as the court may direct, for all services rendered by privately engaged counsel, the public guardian, public administrator, or guardian ad litem, and by counsel for such persons. (f) The court may order the cost of the review and report by a court investigator pursuant to subdivision (b) to be paid out of the proceeds of the transaction or otherwise as the court may direct, if the court determines that its order would not cause a hardship.
