How to use this historical code
Ask which record applies to older paperwork
If a notice shows code 1109, do not silently replace it with the current Princeton code. Give the older code when contacting the court and confirm which record and location apply to that matter. Sources: Historical status: Princeton Historic Preservation Commission (checked September 5, 2026) · Princeton Municipal Court — directory entry: State List of Municipal Courts (roster dated August 31, 2026) · Princeton Municipal Court — Physical address: Princeton Municipal Court (checked September 5, 2026). Open the Princeton Municipal Court guide.
Information to confirm
Case-specific administration of older code 1109 matters is not established.
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.
Current-notice caveat: 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 directory page.
Payment caveat: 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.
