Cal. Prob. Code § 1851.5

Each court shall assess each conservatee in the county for any investigation or review conducted by a court investigator with respect to that person. The court may order reimbursement to the court for the amount of the assessment, unless the court finds that all or any part of the assessment would impose a hardship on conservatee or the conservatee’s estate. There shall be a rebuttable presumption that the assessment would impose a hardship if the conservatee is receiving Medi-Cal benefits.
