District Court Cases in Mercer
New Jersey does not have separate district courts in the traditional sense. Instead, the Superior Court acts as the state's court of general jurisdiction. In Mercer County, the criminal division handles all indictable offenses — serious criminal cases from the first to fourth degrees. After a grand jury indictment, the case is assigned to criminal division judges.
The Civil Division handles claims over $15,000, foreclosure cases, and appeals from municipal courts. Cases are assigned to judges according to the vicinage's internal rules. The Presiding Judge of each division oversees the distribution of workload.
Magistrate Court Cases in Mercer
New Jersey does not have separate magistrate courts. Functions typically performed by magistrate courts in other states are divided between municipal courts and the Special Civil Part of the Superior Court in Mercer County.
Municipal Courts handle:
- Disorderly persons offenses and petty disorderly persons offenses (analogous to misdemeanors)
- Traffic violations, including DWI
- Violations of local ordinances
- Minor criminal cases not requiring indictment
Special Civil Part handles civil cases up to $15,000 and small claims up to $3,000. Landlord-tenant (eviction) cases are also part of this division. These cases are heard in the civil courthouse on South Broad Street.
Family Law, Probate, and Juvenile Matters in Mercer
Family Law
The Family Division of the Superior Court in Mercer handles divorce, child custody, alimony, protective orders from domestic violence, paternity establishment, and termination of parental rights. A divorce complaint is filed in the county where the spouses lived at the time of separation. Closed divorce cases are stored in the courthouse of the county where the decision was made.
Probate Matters
Probate, guardianship, and trust cases are handled by the Mercer County Surrogate's Court. The Surrogate is an elected official who certifies wills and appoints executors. More complex probate disputes are transferred to the Chancery Division — Probate Part of the Superior Court.
Juvenile Matters
The Family Division also handles juvenile delinquency cases and child protection cases (DCPP matters). These records are confidential under New Jersey law. For information on juvenile programs, contact the Family Division at 609-571-4200.
How Cases Move Through the Mercer Court System
The typical progression of a case depends on its category, but the general sequence is as follows:
- Case initiation. A criminal case begins with a complaint or indictment; a civil case with a complaint; a family case with a petition or complaint.
- Judge assignment. The case is assigned to judges in the vicinage according to category and internal rules.
- Initial hearings. In criminal cases — arraignment; in civil cases — case management conference.
- Pre-trial phase. Parties exchange evidence (discovery), file motions. In criminal cases, plea negotiations may occur.
- Trial. A jury or judge renders a verdict. In civil cases, settlement or default judgment is possible.
- Post-judgment. Criminal sentencing, appeal to the Appellate Division, or enforcement of judgment.
Timelines depend on the complexity of the case. Criminal cases with indictable offenses usually take longer than municipal cases for minor offenses.
