New Jersey § 2a:4a-24

§ 2a:4a-24.

a. Except as otherwise provided by law, the court shall have exclusive jurisdiction

in all cases where it is charged that a juvenile has committed an act of delinquency

and over all matters relating to a juvenile-family crisis. Upon the determination that a juvenile has committed an act of delinquency or that

a juvenile-family crisis exists, the court may impose such disposition or dispositions

over those persons subject to its jurisdiction consistent with the purposes of this

act. Such jurisdiction shall extend in these matters over a juvenile and his parent, guardian

or any family member found by the court to be contributing to a juvenile-family crisis. The court shall, in accordance with the Rules of Court, clearly specify the responsibilities

of those subject to its jurisdiction with respect to the plan of rehabilitation for

the juvenile. b. The court shall have jurisdiction in respect to the custody of any juvenile who

may be held as a material witness in any case pending in the court. Whenever a juvenile is a material witness in any other court, the procedures established

by this act shall be followed. c. Juveniles who appear before the court in any capacity shall be deemed to be wards

of the court and protected accordingly. d. Nothing in this act shall affect the jurisdiction of other courts over offenses

committed after a juvenile under the jurisdiction of the court reaches the age of

18 years.
