A predischarge plan of aftercare for a planned discharge of an involuntarily committed minor shall be formulated in cooperation with the minor and the minor's parent, guardian, or other legal custodian. A copy of the plan shall be delivered to the parent, guardian, or other legal custodian. The plan shall:
(1) Specify the services required in the community to meet the minor's needs for treatment, education, housing, nutrition, physical care, and safety;
(2) Specify any income subsidies for which the minor is eligible; and
(3) Identify local and state agencies which can provide services and support to the minor.
The lack of such a plan is not sufficient reason for the continued commitment of a minor when release is otherwise appropriate or required under this title.
