Before an appearance
Use the current notice and the actual charge
Keep the summons or complaint, later notices, and relevant records together. Check the court code, case or ticket number, date, and whether the notice requires an in-person or virtual appearance. For evidence requests and timing, use the municipal-court discovery and adjournments guide; for the charge itself, start with the traffic-defense overview, DWI guide, or criminal-defense overview.
Published addresses and calendars can change or may describe an office rather than the hearing instructions for one case. Follow the latest notice and call the court if it conflicts with this page.
NJMCDirect lists eligible payment options, but paying can resolve a charge as a guilty plea. Understand the effect before using payment to dispose of a case.
