The petitioner’s or proposed guardian’s provision of a proposed hourly fee schedule or another statement of his or her proposed compensation, as required by this paragraph, shall not preclude a court from later reducing the petitioner’s or proposed guardian’s fees or other compensation.

(j) If the proposed ward is or may be an Indian child, the petition shall state that fact.
