Section 5-212. [Resignation, Removal, and Other Post-appointment Proceedings.]
(a) Any person interested in the welfare of a ward or the ward, if 14 or more years of age, may petition for removal of a guardian on the ground that removal would be in the best interest of the ward or for any other order that is in the best interest of the ward. A guardian may petition for permission to resign. A petition for removal or for permission to resign may, but need not, include a request for appointment of a successor guardian.
(b) Notice of hearing on a petition for an order subsequent to appointment of a guardian shall be given to the ward, the guardian, the parents of the ward, provided that the parental rights have not been terminated or a voluntary surrender has not been signed, and any other person as ordered by the court.
(c) After notice and hearing on a petition for removal or for permission to resign, the court may terminate the guardianship and make any further order that may be appropriate, including appointment of a successor guardian.
