California Code, Welfare and Institutions Code - WIC § 5229

At the time a person is ordered to undergo evaluation, or within a reasonable time thereafter, unless a responsible relative or the guardian or conservator of the person is in possession of the person's personal property, the person shall take reasonable precautions to preserve and safeguard the personal property in the possession of or on the premises occupied by the person.  The person responsible for taking him to the evaluation facility shall then furnish to the court a report generally describing the person's property so preserved and safeguarded and its disposition, in substantially the form set forth in Section 5211;  except that if a responsible relative or the guardian or conservator of the person is in possession of the person's property, the report shall include only the name of the relative or guardian or conservator and the location of the property, whereupon responsibility of the person responsible for taking him to the evaluation facility for such property shall terminate.

As used in this section, “responsible relative” includes the spouse, parent, adult child, or adult brother or sister of the person.
