Hampton is a small borough of 1,438 people (2020 census) on about 1.5 square miles in the northwestern corner of Hunterdon County. It sits along Route 31 and the Musconetcong River, right on the Warren County line, between Glen Gardner and Washington Borough. Many residents commute along Route 31 to Interstate 78, Clinton and Flemington.

Route 31 Cases
Route 31 is the main road through Hampton and the source of many of its cases. Common charges include:
- DWI and refusal
- Driving while suspended or unlicensed
- Speeding and reckless driving, which can add points and raise insurance rates
- Possession of drugs or paraphernalia discovered during a stop
Because Hampton borders Warren County, drivers are sometimes unsure which county or court has their case. The location of the offense controls. A stop just north of the Musconetcong may be in Warren County, while a stop in the borough itself belongs to the Hampton court.
Neighborhood and Family Matters
Small-town cases often involve people who know each other: harassment complaints between neighbors, simple assault after a family argument, or criminal mischief involving damaged property. Some of these complaints are filed by private citizens rather than police. A citizen complaint must still be reviewed for probable cause, and many can be resolved through dismissal, mediation or a civil reservation.

Hampton Borough population by census, 1980 to 2020. Source: U.S. Census Bureau via NJ Office of GIS.
Hampton’s population has stayed between about 1,400 and 1,600 since 1980, and was 1,438 in 2020. The borough is small and mostly residential, with Route 31 as its main road. Because it sits on the Warren County line, many people pass through Hampton on their way to Washington, Clinton or Interstate 78.
Serious Charges Go to Flemington
If a Hampton arrest leads to an indictable charge, the case leaves municipal court and moves to the Superior Court at the Hunterdon County Justice Center in Flemington. That includes most drug possession charges, burglary, theft over $200, aggravated assault and weapons offenses. Indictable cases follow a longer process, including possible grand jury review, plea negotiations and pretrial motions.
Options for First-Time Defendants
New Jersey law gives first-time defendants several chances to avoid a conviction. Conditional discharge applies to many drug and paraphernalia charges. Conditional dismissal applies to many other disorderly persons offenses. Pretrial Intervention applies to indictable charges. Each requires an application and has conditions, and each can usually be used only once.
Driving While Suspended: Why It Escalates
Driving while suspended is a common charge on Route 31, and many people underestimate it. A first offense for driving while suspended under N.J.S.A. 39:3-40 carries a fine and an additional license suspension. Penalties rise with each offense, and a third offense can bring jail time.
The stakes jump if the original suspension was for DWI or refusal. Driving during a second or later DWI-related suspension is a fourth-degree crime under N.J.S.A. 2C:40-26, with a mandatory minimum of 180 days in jail without parole. Those cases leave municipal court and go to the Justice Center in Flemington. Before your first court date, it is worth confirming exactly why your license was suspended and whether proper notice was sent. Mistakes in Motor Vehicle Commission records are more common than most people think.
What Is at Stake: Penalties by Offense Level
- Petty disorderly persons offense: up to 30 days in jail and a $500 fine
- Disorderly persons offense: up to 6 months in jail and a $1,000 fine
- Fourth-degree crime: up to 18 months in prison
- Third-degree crime: 3 to 5 years
- Second-degree crime: 5 to 10 years
- First-degree crime: 10 to 20 years, and longer for some offenses

Maximum jail exposure rises sharply once a charge becomes an indictable crime.
How We Approach a Hampton Case
For Hampton cases, we start by confirming which court has jurisdiction, since the borough sits on the county line. We then gather the police report and any video, and review the stop, search and arrest for legal problems.
Most Hampton cases are municipal matters, and our goal is usually to avoid a criminal record through diversion, dismissal or an amendment. For DWI, we review the Alcotest and field sobriety tests. In neighbor disputes and citizen complaints, we look for ways to resolve the case without a conviction, including mediation where appropriate.
