California Code, Probate Code - PROB § 1851.6

(a) Any interested person, as defined in Section 48 or any person entitled to receive notice pursuant to Section 1822, if they have personal knowledge of a conservatee, may petition the court to investigate an allegation of abuse, as defined by Section 15610.07 of the Welfare and Institutions Code, of the conservatee by a conservator.  The court shall investigate all such allegations that establish a prima facie case of abuse.  If the court investigator has performed an investigation within the preceding six months and reported the results of that investigation to the court, the court may order, upon good cause shown, that a new investigation is not necessary or that a more limited investigation is sufficient.

(b) A superior court shall not be required to perform any duties imposed pursuant to this section until the Legislature makes an appropriation identified for this purpose.
