New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 4A-41

Where a juvenile is adjudicated delinquent, the disposition of the case shall be entered within 30 days of such adjudication if the juvenile has been placed in a detention center or shelter-care facility. If the juvenile is so placed and no disposition of the case is made after 30 days, the court shall, upon motion of the juvenile, fix a date certain for the dispositional hearing which shall be within 10 days of the motion, unless an extension is granted by the court for good cause shown. Disposition shall be made in all other cases within 60 days unless an extension is granted by the court where good cause is shown. The court shall provide written notice to the proper parties as to the date, time and place of such hearing and do so sufficiently in advance of the hearing to allow adequate time for preparation.
