When it appears to the court’s staff that, because of a violation of law or of a supervisory order, a child under the court’s jurisdiction should be removed from the child’s home or that the child’s probation should be revoked, or special conditions imposed, it shall file a motion for review and change of decree. Such motion shall include a statement of the facts and shall set forth the reasons for the proposed review and change.

Upon receipt of the motion, the court may order a hearing to determine the allegations of the motion.

The court may modify a condition of protective supervision or probation included in its decree. Such modification shall be given to the parties in writing, and the parties may petition the court to hold a hearing on the advisability of the modification.
