In Somerset County, the path from arrest to a judge’s release decision now crosses county lines. Since October 2024, everyone taken into custody in Somerset County is processed at the Somerset County Jail in Somerville and then transferred to the Morris County Correctional Facility in Morristown. Their case, however, stays at the Somerset County Courthouse on North Bridge Street. That is where a Superior Court judge decides at the first appearance, and sometimes at a detention hearing, whether they will be released while the case is pending.
This page focuses on what Somerset County families most often ask about: how the detention hearing works, what evidence the judge hears, and how to prepare.

From Arrest to First Appearance
Most Somerset County arrests come from local departments in towns such as Bridgewater, Franklin Township, Hillsborough, North Plainfield, Bound Brook, Bernards Township, Montgomery and Somerville, or from troopers patrolling Interstates 287 and 78. When police charge an indictable crime on a complaint-warrant rather than a summons, the person is booked in Somerville and moved to Morris County.
A judge must hold the first appearance within 48 hours of the person’s commitment to jail. Defendants in Morris County custody usually appear by video. Before the hearing, Somerset Pretrial Services prepares the Public Safety Assessment (PSA), which produces two 1-to-6 scores. One measures the risk of failing to appear and the other the risk of new criminal activity. A separate flag marks a risk of new violent criminal activity. Pretrial Services then makes a recommendation based on those scores and the charge.
In most cases, the first appearance ends with release on conditions. If the Somerset County Prosecutor’s Office has filed a motion to detain, the judge will schedule a detention hearing instead.

Inside a Somerset County Detention Hearing
A detention hearing is the most important pretrial proceeding in New Jersey. It works like a short trial on a single question: can any set of release conditions manage the risks in this case?
Timing
The hearing takes place at the first appearance unless the State asks for up to three working days or the defense asks for up to five. Defendants stay in custody until the hearing.
Discovery comes first
Before the hearing, the prosecutor must turn over the evidence it relies on. That includes the affidavit of probable cause, police reports, statements and other materials in the State’s possession. Reviewing this discovery quickly is often where the defense finds its strongest arguments.
Probable cause
If the defendant has not yet been indicted, the State must establish probable cause for the charge. The defense can challenge it. A weak affidavit can lead to a release order, or even to a downgraded charge.
The standard of proof
To detain someone, the State must prove by clear and convincing evidence that no amount of monetary bail, no non-monetary conditions and no combination of the two would reasonably assure the defendant’s appearance, protect the community and prevent obstruction. Murder and life-sentence offenses carry a rebuttable presumption of detention. Every other charge carries a presumption of release.
Evidence and witnesses
Hearings usually proceed by proffer, with each side summarizing its evidence. The defense may call witnesses and present documents. In some cases the defense can cross-examine a detective, which gives an early chance to test the State’s version of events.
What the judge considers
The judge looks at the nature of the charge, the weight of the evidence, the defendant’s history and character, any danger to a particular person, and the PSA recommendation. The judge must explain the decision in writing or on the record.
Somerset County’s 2024 Detention Numbers
Somerset County stands out in the New Jersey Judiciary’s 2024 Criminal Justice Reform statistics as a county where detention motions are pursued firmly:
- Warrants: Somerset charged 1,156 defendants, and 644 of them (55.7 percent) were charged on complaint-warrants, above the statewide 44.7 percent.
- Detention motions: Prosecutors filed motions for 280 defendants, about 43.5 percent of those held on warrants, slightly above the statewide 42.8 percent.
- Few withdrawals: Only 13.6 percent of Somerset motions were withdrawn or dismissed, compared with 20.8 percent statewide.
- Outcomes: Of the 242 motions judges decided, 149 were granted (61.6 percent) and 93 were denied (38.4 percent), close to the state average.
- Bottom line: 23.1 percent of Somerset warrant defendants were detained at the initial decision, compared with 21.1 percent statewide. About 75 percent were released.

What these numbers mean in practice: in Somerset County, once a detention motion is filed, it is likely to be heard. Nearly 4 in 10 decided motions are denied, so a well-prepared defense has a real chance. But the defense should plan for a contested hearing rather than hope the motion will be dropped.
Conditions of Release
If the judge orders release, conditions fall into tiers supervised by Somerset Pretrial Services:
- Release on own recognizance
- Pretrial Monitoring Level 1, 2 or 3, with scheduled reporting
- Level 3+ with electronic monitoring or home detention
- Special conditions, such as no contact with a victim or witness, firearm surrender, drug testing, or a curfew
Violating a condition can lead to a motion to revoke release, so understanding each condition matters.
Preparing for the Hearing: A Checklist
Detention hearings move fast. In the days before a Somerset hearing, the defense team typically works through:
- Reviewing the affidavit of probable cause, police reports and any video produced in discovery
- Checking the criminal history the PSA relied on for errors or duplicate entries
- Confirming a release address and speaking with the people who live there
- Collecting employment, school and treatment documentation
- Identifying witnesses who can speak to the defendant’s reliability
- Proposing specific conditions, such as reporting, curfew, no-contact orders or monitoring, that answer the State’s concerns
Cases Where Somerset Prosecutors Often Seek Detention
- Firearms charges, particularly when combined with drug charges
- Domestic violence-related crimes involving injury or a weapon
- Robbery, carjacking and burglary of an occupied home
- Repeat offenses while already on pretrial release or probation
- Large-quantity drug distribution charges investigated by the county narcotics task force
Options After a Detention Order
The defense can appeal a detention order to the Appellate Division on an expedited basis. It can also ask the court to reopen the hearing based on a material change, such as an available residence or a treatment placement. New Jersey’s speedy-trial rules also cap pretrial detention. The State generally must indict within 90 days and begin trial within 180 days after indictment, excluding delays that the rules allow.
Helping a Family Member in Custody
- Do not expect to visit in Somerville. After booking, the person is housed in Morris County, so check that facility’s rules.
- Collect documents that support release: a lease, pay stubs, school enrollment or medical records.
- Avoid discussing the case on recorded jail calls or in messages.
- Contact a defense attorney as early as possible so a release plan is ready at the first appearance.
Frequently Asked Questions
Where will my family member be released from?
Because detainees are housed in Morris County after booking, a release may be processed from Morristown rather than Somerville. Call the facility or ask the defense attorney to confirm where and when to pick your family member up.
Are hearings in person or virtual?
Both happen. The defendant typically appears by video from custody, and attorneys may appear in person in Somerville or remotely, depending on the judge’s schedule.
What if the case started in a municipal court?
Indictable charges filed in a municipal court in Somerset County are sent to the Superior Court for the first appearance and detention process. Lower-level disorderly persons charges usually stay in the municipal court.
How often does Somerset County detain defendants?
In 2024, about 23 percent of Somerset defendants held on complaint-warrants were detained at the initial decision, slightly above the statewide rate of about 21 percent, according to New Jersey Judiciary statistics.
Can a detention hearing be postponed so I can hire a lawyer?
The defense can ask for a short continuance of up to five working days. The defendant stays in custody during that time, so many families hire counsel before the first appearance to avoid the delay.
Does the judge see the PSA score?
Yes. The judge receives the Public Safety Assessment and the Pretrial Services recommendation. The defense can challenge errors in either one.
