The response of the person appointed to respond to the offer on behalf of the minor is subject to approval by the court. Within 15 days after a response to a qualified offer is filed with a court under subsection (b)(3) of this section, the court: May hold a hearing; and Shall approve or disapprove the response to the qualified offer. If a court disapproves the response to the qualified offer filed by the person acting on behalf of the minor, the court may order: That an additional response be filed on behalf of the minor; or Any action the court considers necessary and appropriate to protect the interests of the minor. If the court approves a response accepting a qualified offer on behalf of the minor, the order of the court shall designate one or more persons who shall be responsible for and authorized to make all decisions on behalf of the minor necessary to implement the qualified offer.
