Cal. Probate Code § 2017

(a) A third person who acts in good faith reliance on a conservatorship order registered under this article is not liable to any person for so acting if all of the following requirements are satisfied: (1) The conservator presents to the third person a file-stamped copy of the registration documents required by Section 2011, 2012, or 2013, including, but not limited to, the certified copy of the conservatorship order. (2) Each of the registration documents, including, but not limited to, the conservatorship order and the file-stamped cover sheet, appears on its face to be valid. (3) The conservator presents to the third person a form approved by the Judicial Council, in which the conservator attests that the conservatee does not reside in this state and the conservator promises to promptly notify the third person if the conservatee becomes a resident of this state. The form shall also prominently state that the registration is effective only while the conservatee resides in another jurisdiction and does not authorize the conservator to take any action while the conservatee is residing in this state. (4) The third person has not received any actual notice that the conservatee is residing in this state. (b) Nothing in this section is intended to create an implication that a third person is liable for acting in reliance on a conservatorship order registered under this article under circumstances where the requirements of subdivision (a) are not satisfied. Nothing in this section affects any immunity that may otherwise exist apart from this section.
