Cal. PROB § 1517

(a) This part does not apply to guardianships resulting from the selection and implementation of a permanent plan pursuant to Section 366.26 of the Welfare and Institutions Code. For those minors, Section 366.26 of the Welfare and Institutions Code and Division 3 (commencing with Rule 5.500) of Title Five of the California Rules of Court specify the exclusive procedures for establishing, modifying, and terminating legal guardianships. If no specific provision of the Welfare and Institutions Code or the California Rules of Court is applicable, the provisions applicable to the administration of estates under Part 4 (commencing with Section 2100) govern so far as they are applicable to like situations.

(b) This chapter shall not be construed to prevent a court that assumes jurisdiction of a minor child pursuant to Section 300 of the Welfare and Institutions Code, or a probate court, as appropriate, from issuing orders or making appointments, on motion of the child’s counsel, consistent with Division 2 of the Welfare and Institutions Code or Divisions 4 to 6, inclusive, of the Probate Code necessary to ensure the appropriate administration of funds for the benefit of the child. Orders or appointments regarding those funds may continue after the court’s jurisdiction is terminated pursuant to Section 391 of the Welfare and Institutions Code.
