Cal. Welf. and Inst. Code § 5371
No person upon whom a duty is placed to evaluate, or who, in fact, does evaluate a conservatee for any purpose under this chapter shall have a financial or other beneficial interest in the facility where the conservatee is to be, or has been placed.
Conservatorship investigation and administration shall be conducted independently from any person or agency which provides mental health treatment for conservatees, if it has been demonstrated that the existing arrangement creates a conflict of interest between the treatment needs of the conservatee and the investigation or administration of the conservatorship. The person or agency responsible for the mental health treatment of conservatees shall execute a written agreement or protocol with the conservatorship investigator and administrator for the provision of services to conservatees. The agreement or protocol shall specify the responsibilities of each person or agency who is a party to the agreement or protocol, and shall specify a procedure to resolve disputes or conflicts of interest between agencies or persons.
