Criminal records of Mercer County, New Jersey, are available through several channels — online tools, state court systems, law enforcement agencies, and the court clerk's office. MercerNJCourt.us allows you to search publicly available information about criminal cases in the county.

How to Search Criminal Records in Mercer
Start your search with MercerNJCourt.us — a resource that compiles public information about county court cases. You will need at least one of the following to search:
- Full name of the defendant
- Date of birth
- Case number
Online Search via State Portals
The New Jersey court system supports several free databases.
- The PROMIS/Gavel Public Access system is specifically designed for Superior Court criminal cases. Enter the last name or case number. Some records are restricted according to state judicial rules.
- Municipal Court Case Search — for municipal court cases: traffic violations, disorderly persons offenses, and other complaints.
- The Find a Case page on the NJ Courts website consolidates links to all available databases.
Separately, the state Department of Corrections maintains an offender registry, where you can check if a person is under supervision or in a correctional facility.
In-Person Visit
The Mercer County Criminal Court is located separately from the civil court.
The courthouse has public access terminals. A clerk will help you find a case by last name or number — just approach the criminal division registration desk.
Written Request
For closed cases or cases not available in online databases, fill out form CN 10200 (Records Request Form). The form can be mailed or submitted in person. Choose the delivery method — pickup, US mail, or email — directly on the form. To obtain an official criminal history record, contact the New Jersey State Police, which is the repository of the state's criminal records.
Search Mercer Criminal Cases by Case Number
A New Jersey case number has a clear structure, and each part carries specific information. The typical format for a Superior Court criminal case looks like this:
Example: 11-01-0001-I
- 11 — county code (Mercer has code 11 in the state judicial system)
- 01 — year the case was opened (two digits)
- 0001 — sequential case number
- I — letter indicating the type of case (e.g., "I" for indictment)
If you have the full number, enter it into the PROMIS/Gavel system — the search will yield results faster than by last name. Municipal cases have a different numbering format; use the separate municipal court portal for them.
