(a) After service of the summons and petition of the ward or any person interested in his welfare, the court may remove a guardian and appoint a successor if in the best interests of the ward. On petition of the guardian, the court may accept his resignation and make any other order which may be appropriate.
(b) An order adjudicating or readjudicating incapacity may specify a minimum period, not exceeding one year, during which no petition for an adjudication that the ward is no longer incapacitated may be filed without special leave. Subject to this restriction, the ward may make a request for an order from the court that he is no longer incapacitated, and for removal of the guardian. A request for this order may be made by informal letter to the court or judge and any person who knowingly interferes with transmission of this kind of request to the court or judge may be adjudged guilty of contempt of court.
(c) Before acting upon any such petition or request, the court shall send a visitor to the residence of the present guardian and to the place where the ward resides or is detained to observe conditions and report in writing to the court. After reviewing the report of the visitor, the court may order termination of the ward's incapacity or a hearing following the procedures set forth in Section 62-5-303.
