N.J. Ct. R. 4:5A-2

(a) Notice of Track Assignment. Within ten days after the filing of the complaint, the court shall mail a notice of track assignment to the plaintiff. The plaintiff shall annex a copy of the notice to process served on each defendant.

(b) Change of Track Assignment. Within 30 days after receipt of the track assignment notice, plaintiff may apply to the court for a change of track assignment by filing a certification of good cause. Any party other than the plaintiff seeking a change of track assignment shall file and serve a certification of good cause with its first pleading and any objection thereto shall be made by responding certification filed and served within ten days. Any party aggrieved by the court's determination on such application may seek relief therefrom by motion filed and served within 15 days thereafter. After the expiration of the time periods herein prescribed, a track assignment may be changed by the court on its own motion or motion of a party only if the fundamental cause or causes of action have changed or if the case type or track was erroneously identified on a party's Case Information Statement or erroneously entered into the automated docket. A track assignment shall not, however, be changed, during or after the time periods herein prescribed, either because of the alleged complexity of the case or on a representation by a party that additional discovery is required. In such event, relief may be sought pursuant to R. 4:24-1.
