When a teenager is accused of a gun or weapons offense, the case usually stays in juvenile court, not adult criminal court. A child who is held in custody first gets a detention hearing, then a hearing on whether the allegations are true, then a disposition hearing. In some states, including California, a serious weapons case can also bring a hearing on transfer to adult court.
Most people facing this situation are parents or guardians who got a phone call they never expected. Their child has been arrested, may be sitting in juvenile hall, and they are trying to work out what a gun allegation means, whether their child could be tried as an adult, and what it will mean for school and for the years ahead. This page explains each step in plain terms, using California's rules as the worked example and showing where other states differ. For an overview of other offenses heard in juvenile court, see our juvenile crimes hub.
What Juvenile Gun and Weapons Charges Mean Under the Law
A juvenile case starts with a petition, the document that sets out what the minor is accused of. It is not a criminal complaint. The court then holds a jurisdiction hearing (also called an adjudication hearing) to decide whether the allegations are true. If they are, a disposition hearing follows, where the court decides what happens next. The court may also make the minor a ward of the court, which means the juvenile court takes on supervision of the child.
In California, Welf. & Inst. Code § 602 gives the juvenile court jurisdiction over a minor between 12 and 17, inclusive, who violates a state or federal law, or a local ordinance defining a crime, except as Welf. & Inst. Code § 707 provides. That is California's rule. Other states set different age ranges.
Juvenile courts are built around rehabilitation. A gun allegation, though, is among the more serious matters these courts hear, and it can open the door to extra proceedings such as a transfer hearing. A juvenile defense attorney at this early stage looks at which charge was filed, because the charge shapes everything that follows.
Common Gun and Weapons Offenses Alleged Against Minors
Gun and weapons allegations against minors tend to fall into a few broad groups:
- possession of a firearm by a minor
- carrying a concealed weapon
- possession of a weapon on school grounds
- brandishing, meaning displaying a weapon in a threatening way
- use of a weapon during another offense
A weapon found at school often leads to two separate tracks: the court case and the school's own discipline process. Our page on juvenile charges and school explains how the two relate.
Federal law adds another layer. 18 U.S.C. § 922(x) is a federal statute that generally restricts possession of handguns by persons under 18, subject to exceptions the statute lists. Federal juvenile cases are handled differently from state juvenile cases, and most gun allegations against teenagers are brought in state court.
The exact charge matters. An attorney for juvenile charges reads the petition closely, because the specific offense alleged decides whether a transfer hearing is even possible. In California, Welf. & Inst. Code § 707(b) names specific serious offenses. Whether a gun allegation falls within that list depends on the precise offense charged.
How a Juvenile Gun Case Moves Through Court
For most families, the first hours after an arrest are the most confusing, so it helps to walk through them in order.
In California, the process begins when police take a minor into temporary custody and bring the minor to the probation officer. Under Welf. & Inst. Code § 628, the probation officer must immediately look into what happened and release the minor to a parent, guardian or responsible relative. The exception is where the evidence shows that going home is contrary to the minor's welfare and at least one of three conditions exists:
- detention is urgently necessary to protect the minor, or reasonably necessary to protect another person or property
- the minor is likely to flee
- the minor has violated a juvenile court order
If the child is not released, two clocks start running. Under Welf. & Inst. Code § 631, a detained minor generally must be released within 48 hours, excluding nonjudicial days, unless a petition has been filed in that time. Under Welf. & Inst. Code § 632, a minor still in custody must then be brought before a judge or referee for a detention hearing, the hearing that decides whether the child stays in custody. It must happen as soon as possible, and no later than the end of the next judicial day after the petition is filed. If the hearing does not happen in that time, the minor must be released.
The detention hearing is often the first time a parent sees the judge, and it is about custody, not guilt. Welf. & Inst. Code § 635 requires the court to release the minor unless grounds like those in § 628 appear, or the minor has escaped from a juvenile court commitment. The court may weigh the circumstances and gravity of the alleged offense along with other factors, which is one reason a gun allegation can make release harder to obtain. Under Welf. & Inst. Code § 636, a detention order lasts no more than 15 judicial days. Both sections also give a minor equal consideration for release on home supervision, which may include electronic monitoring, regardless of whether the minor lives in the county where the offense occurred. In practice, that means a child from another county is not ruled out of home supervision for that reason alone. It is not a general preference for home supervision.
Other states run on different clocks. The OJJDP case flow overview says detention hearings generally take place within 24 hours, within a time period each state sets by statute.
At the jurisdiction hearing, the court decides whether the petition's allegations are true. A sustained petition is not a conviction. At the disposition hearing, the court may order probation, which is court supervision with conditions, or placement or other outcomes. Some cases are instead handled through diversion or informal supervision. Whether that is available depends on the offense, the minor's history and the court, as our page on whether juvenile charges can be dismissed explains. A juvenile criminal defense attorney can appear for the minor at each of these hearings.
Transfer to Adult Court: What the Law Requires
A transfer hearing, called a fitness hearing in some places, is where a juvenile court decides whether a minor's case should move to adult criminal court. In California, transfer is not automatic.
Under Welf. & Inst. Code § 707(a), the prosecutor may make a transfer motion only in two situations:
- the offense was allegedly committed when the minor was 16 or older, and it is either an offense listed in § 707(b) or any other felony
- the offense is a § 707(b) offense allegedly committed at 14 or 15, by a person who was not apprehended before juvenile court jurisdiction ended
The motion must be made before jeopardy attaches. The court then orders a probation report on the minor's behavioral patterns and social history.
The court may order a transfer only if it finds, by clear and convincing evidence, that the minor is not amenable to rehabilitation while under the jurisdiction of the juvenile court. In plain terms, the court weighs whether the juvenile system can realistically help this young person before its authority ends. Its criteria include the degree of criminal sophistication the minor showed. If the court orders transfer, it must state its reasons in an order. The court also postpones any plea until the transfer hearing ends.
These are California's rules. Ages, offense lists and procedures differ significantly from state to state. The OJJDP overview notes that some states let prosecutors file certain cases directly in criminal court. A minor who is transferred faces the case as an adult criminal matter, with adult consequences that can include adult incarceration. A juvenile defense attorney can present evidence at a transfer hearing, including evidence about the minor's prospects for rehabilitation.
A Minor's Rights When Questioned by Police
The U.S. Supreme Court held in In re Gault, 387 U.S. 1 (1967), that a minor facing delinquency proceedings that could result in confinement has due process rights. Those rights include notice of the charges, the right to counsel, the privilege against self-incrimination and the right to confront witnesses. They are grounded in the Constitution.
California goes further. Under Welf. & Inst. Code § 625.6, before a custodial interrogation and before any waiver of Miranda rights, a youth 17 years of age or younger must consult with legal counsel in person, by telephone or by video conference. The consultation cannot be waived. When a court decides whether the youth's statements can be used, it must consider any failure to follow this rule.
There are two limits. The section does not govern admissibility when an officer reasonably believed the information was needed to protect life or property from an imminent threat and kept the questions to what was reasonably necessary. It also does not require probation officers to follow it in their normal duties under specified sections.
This is California's rule, and other states handle questioning of minors differently. For an attorney for a minor charged with a crime, whether these protections were followed is often one of the first questions about a statement the child made.
Collateral Consequences of a Juvenile Gun Adjudication
The consequences of a sustained petition for a weapons offense can reach well past the disposition itself.
School. Schools can run their own disciplinary process, separate from the court case. School discipline rules vary, and this page does not cover them in detail.
Firearms. An adjudication for certain offenses can restrict firearm possession as an adult. The restrictions depend on the offense and the state. California's Welf. & Inst. Code § 786 refers to sustained petitions that make a person ineligible to own or possess a firearm until age 30.
Records. A juvenile record is not sealed automatically at 18. In California, Welf. & Inst. Code § 786 requires the court to dismiss the petition and seal the records when a person satisfactorily completes informal supervision under § 654.2, probation under § 725, or a term of probation for any offense. Once the petition is dismissed, the arrest and proceedings are deemed not to have occurred.
There is an important exception in § 786(d). The court shall not seal or dismiss under § 786 if the petition was sustained on a § 707(b) offense committed at 14 or older. That bar lifts only if the finding on that offense was dismissed, or was reduced to a misdemeanor or to a lesser offense not listed in § 707(b).
Sealing by petition under Welf. & Inst. Code § 781 is ordered only if the court finds two things. First, since jurisdiction ended, the person has not been convicted of a felony or of any misdemeanor involving moral turpitude. Second, rehabilitation has been attained to the court's satisfaction. For a § 707(b) offense committed after age 14 that resulted in wardship, a petition may be filed or considered only in the circumstances § 781(a)(1)(D) lists. These are California's rules.
Other effects. Immigration consequences are governed by immigration law this page does not cover; see juvenile charges and immigration. Employment, college admissions and financial aid can also be affected, depending on the facts and on rules this page does not cover.
What a Juvenile Defense Attorney Does in a Gun Case
A juvenile defense attorney represents the minor at every stage of the case: the detention hearing, the jurisdiction hearing, disposition, and any transfer hearing. Early decisions carry weight. What happens at the detention hearing, and whether a transfer motion is filed, can shape the rest of the case.
In gun cases, defense work commonly includes asking three questions:
- was the weapon or other evidence lawfully obtained?
- were the minor's rights, including any California § 625.6 consultation, respected during questioning?
- what disposition options does the law allow?
None of this guarantees a particular result. What the law allows always depends on the facts and the court.
