Trenton Criminal Court Process

Criminal cases in Trenton follow the standard New Jersey court process. The type of charge determines which court handles the matter. Disorderly persons offenses go through Trenton Municipal Court. Indictable crimes, which are equivalent to felonies in other states, are handled by the Mercer County Superior Court, Criminal Division.

When someone is arrested in Trenton, the case begins with a complaint. Under the Criminal Justice Reform Act of 2017, codified at N.J.S.A. 2A:162-15, most defendants receive a pretrial risk assessment instead of cash bail. This changed how booking and release work at the Mercer County Correctional Center at 1750 River Road. A Public Safety Assessment score helps judges decide whether to release or detain a defendant before trial.

For indictable offenses, the Mercer County Prosecutor presents the case to a grand jury. If the grand jury returns an indictment, the case moves to Superior Court for arraignment, discovery, and potentially trial. All of these steps generate records that become part of the criminal history file in Trenton. Plea agreements, trial verdicts, and sentencing orders are all recorded by the court clerk.

Municipal court cases in Trenton cover lesser offenses. These include disorderly persons charges, petty disorderly persons offenses, and motor vehicle violations with criminal penalties such as DWI. The municipal court judge can impose fines, probation, and jail sentences of up to six months for these charges. Records from municipal court proceedings in Trenton are also part of a person's criminal history in the state system.

Criminal History Expungement in Trenton

Expungement removes a criminal record from public view. Trenton residents who qualify can petition the Mercer County Superior Court to have eligible records expunged. The process is governed by N.J.S.A. 2C:52-1 through 2C:52-32.

New Jersey expanded its expungement law in recent years. The "Clean Slate" law, effective in 2020, allows expungement of certain criminal records after specific waiting periods. For indictable offenses, the wait is generally six years from the completion of the sentence. Disorderly persons offenses can be expunged after five years. Some drug offenses may qualify sooner. Trenton residents can contact the Expungement Clerk at the Mercer County Criminal Courthouse by calling (609) 571-4200, extension 74048, for guidance on the process.

Filing an expungement petition requires several steps. You need to gather your criminal history, complete the petition forms, and file them with the court. The petition must be served on all relevant parties, including the Mercer County Prosecutor, the Attorney General, and any law enforcement agency involved in the original arrest. A hearing date is set, and the judge reviews the petition.

Note: Successful expungement in Trenton means the criminal history record is isolated and cannot be seen through standard public record searches.

The state also launched an automated expungement process for certain marijuana-related offenses under N.J.S.A. 2C:52-6. Trenton residents with qualifying marijuana convictions may have their records cleared without filing a petition. The Administrative Office of the Courts manages this process statewide.
