Juvenile Detention Hearing Lawyer in Hudson County, NJ

Reviewed by William A. Proetta, Esq. · Updated October 2026

Under N.J.S.A. 2A:4A-34, a child charged with delinquency in New Jersey is released to a parent or guardian unless a judge or the court intake service approves detention, and detention is allowed only for a recent willful failure to appear, an active warrant, or a serious threat to community safety tied to a qualifying offense. A detained child must have a hearing “no later than the morning following” placement in detention, weekends and holidays included, followed by a probable cause determination within 2 court days, review hearings within 14 court days and then at least every 21 court days, and a trial within 30 days of detention (2A:4A-38).

In Hudson County, detention hearings are heard in the Family Part on the third floor of the Frank J. Guarini Justice Complex, 24 Central Avenue, Jersey City, where Judge Martha Mainor currently handles all juvenile cases. Juveniles who are not released are held at a county juvenile detention center. I have more than 15 years of criminal trial experience, and when a parent calls us at night, we prepare for the next-morning hearing that same night. Call (201) 793-8018.

Detention Under N.J.S.A. 2A:4A-34 in Plain English

The statute starts from release. “No juvenile shall be placed in detention without the permission of a judge or the court intake service.” Before a child can be held, the decision-maker must consider less restrictive alternatives: release to a parent or guardian, release on a promise to appear, or home detention.

Detention is permitted only on one of three grounds:

1. A recent willful failure to appear in court. “Recent” means within the last 12 months, or within 12 to 24 months if the child has not voluntarily come back to court since.
2. An active warrant for the child.
3. A serious threat to the safety of the community connected to the offenses the statute lists.

Two more limits apply. A child 11 or younger can be detained only for a first- or second-degree crime or arson. And the judge must state the reasons for detention on the record, which gives us something concrete to answer at each review.

There is no bail in the juvenile system (N.J.S.A. 2A:4A-40). Release does not depend on money. It depends on whether the court is satisfied that your child will come back to court and that the community will be safe, and on whether a responsible adult is ready to take your child home. Adults charged in the same building face a different process under the Criminal Justice Reform Act, which we explain on our page on New Jersey pretrial release and detention.

Summons or Warrant: How a Child Ends Up Detained

Most Hudson County juvenile cases start with a complaint-summons, and a child who gets a summons goes home. Under Attorney General Directive 2020-12, a summons is the presumed charging document. A complaint-warrant, which can lead to detention, is issued only when Court Intake Services or a judge authorizes detention.

The Directive makes a warrant mandatory for murder, aggravated manslaughter, manslaughter, aggravated sexual assault, sexual assault, robbery, carjacking and escape, and for attempts or conspiracies to commit them. It creates a rebuttable presumption of a warrant for firearm offenses, certain second-degree crimes and offenses committed while the child was on release or probation. A warrant does not settle whether your child stays held; the judge decides that at the detention hearing the next morning.

Before any of that, a child picked up by Jersey City, Hoboken or Bayonne police may be held at the police station only briefly. N.J.S.A. 2A:4A-37 permits a station hold only in a non-prisoner area, only to arrange release, and only with the child kept apart from adults charged with or convicted of crimes. The Directive caps that hold at 6 hours from entry into the department. Police must also notify you immediately when they take your child into custody (2A:4A-33). If officers want to question your child during that time, the rules on our page about police questioning of minors apply.

The Detention Hearing Timeline

Each deadline comes from the statute.

If the 30-day trial deadline passes, the court must set a date certain within 72 hours of a motion by the defense, unless it grants an extension for good cause. Each review hearing is a fresh chance at release: a family situation gets sorted out, a program accepts the child, or the State’s evidence looks thinner than it did on the first morning.

Where Hudson County Juveniles Are Held

A juvenile may be detained only in a facility designated by the Youth Justice Commission (formerly the Juvenile Justice Commission), or placed in shelter care designated by the Department of Children and Families (2A:4A-37). No child may be placed in a facility that is at maximum capacity. Hudson County juveniles who are detained are held at a county juvenile detention center designated for that purpose, and we confirm the location with you as soon as a hold is ordered.

Detention means “physically restricting facilities.” Shelter care is the same temporary care without physical restriction (2A:4A-22). For lesser charges, a child may be placed in a shelter or other non-secure setting when no parent or guardian can be found or is willing to take custody (2A:4A-34). That is why a parent’s presence at the first hearing matters so much.

A child who turns 18 while a case is pending is not moved to the county jail automatically. For ages 18 and 19, the court decides where the person is held. At 20 or older, the default is the county jail unless good cause is shown.

Release, Conditions and Home Detention

The alternatives the statute names are release to a parent or guardian, release on a promise to appear and home detention, which keeps your child at home under conditions the court sets.

The judge will want to know who will supervise your child, where your child will live and attend school, and how your child will get to every court date. A specific plan answers those questions before they are asked. If the case may be resolved outside court, our page on juvenile diversion in Hudson County explains those options, and we raise them with the Hudson County Prosecutor’s Office, which is in the same building, as early as the first hearing.

How Parents Should Prepare for the Hearing

The hearing is often over in minutes. What you bring can decide whether your child comes home.

Be there, early. A parent or guardian in the courtroom, ready to take the child home, is the strongest release argument. If you cannot attend, send a responsible relative.

Bring documents. Your ID, proof of your address, your child’s school name and schedule, any IEP or 504 plan, the names of doctors or counselors and a list of medications.

Have a supervision plan. Who is home after school, who drives your child to court and how you will make sure your child follows any curfew or condition.

Do not talk about the facts. Not on the phone from the station or detention center, and not in the hallway. Save it for the private conversation with us.

Stay calm and polite. Short, respectful answers to the court’s questions help.

If the charge is one the prosecutor may try to move to adult court, the detention hearing is the first time we see the State’s position. Our page on waiver to adult court explains that process. Disposition terms that include short-term county detention are a separate matter covered on our page on juvenile sentencing, and the full sequence of a case is on our Hudson County juvenile defense overview.
