When a child is accused of assault, the case usually goes to juvenile court, not adult criminal court. A judge decides whether the child stays in custody, whether the allegation is proved and what the consequences will be. In some serious cases a court can move the case to adult court. Juvenile records can sometimes be sealed, but sealing is not automatic at 18.
Most people facing this are parents who got a phone call from a school, a police station or juvenile hall and are now trying to understand words they have never had to know. They are worried about whether their child is coming home tonight, what this means for school and whether one fight or one bad afternoon will follow their child for years. This page walks through how a juvenile assault case works, step by step, using California's rules as the detailed example and saying plainly where other states differ.
What Juvenile Assault Charges Mean Under the Law
Assault, in plain words, generally means an unlawful attempt or threat to cause someone physical harm. Battery generally means the actual harmful or offensive contact. Each state defines these offenses in its own law, and the exact elements, meaning what the prosecution has to prove, depend on that state's statutes.
Juvenile court uses its own vocabulary. The charging document is a petition, a written request asking the court to find that the child committed the offense, rather than a criminal complaint. If the court finds the allegation true, that finding is an adjudication, not a conviction. A juvenile defense attorney uses these terms because the law treats them differently from their adult versions.
Juvenile court generally covers minors, which in most states means people under 18, though the age range varies by state. In California, Welf. & Inst. Code § 602 places a minor between 12 and 17 years of age, inclusive, within juvenile court jurisdiction when the minor violates a state or federal law or a local ordinance defining crime, other than an age-based curfew ordinance, except as § 707 provides. A child under 12 comes within it only for the offenses § 602(b) lists: murder, and rape, sodomy, oral copulation or sexual penetration by force, violence, duress, menace or fear of immediate and unlawful bodily injury.
Assault allegations range from simple assault to aggravated assault, depending on the facts alleged. Juvenile court is built around rehabilitation, which shapes how judges approach these cases. California's version of these rules is covered in more depth in our page on California juvenile assault charges.
How a Juvenile Assault Case Moves Through Court
According to the OJJDP case flow overview, each state's processing of juvenile cases is unique, and even within states it varies by community. The general shape, though, is similar.
The charging decision. After an arrest or citation, law enforcement decides whether to send the matter on or divert it, and court intake, generally the probation department or prosecutor's office, then decides whether to dismiss it, handle it informally or ask for formal court intervention.
Diversion. Diversion means resolving a case outside formal court proceedings, often through a program with conditions. Some assault cases may be handled this way, depending on the facts and the jurisdiction. California law refers to an informal program of supervision.
The detention hearing. A detention hearing is the court hearing that decides whether a child stays in custody while the case goes on. In California, when a minor is delivered to the probation officer, § 628 requires immediate release to a parent, guardian or responsible relative unless continuing in the home is contrary to the minor's welfare and one of three conditions exists: urgent necessity to protect the minor or reasonable necessity to protect another person or property, a likelihood of fleeing, or violation of a juvenile court order. Under § 631, a minor generally must be released within 48 hours, excluding nonjudicial days, unless a petition is filed. Under § 632, a detained minor must be brought before the court before the next judicial day ends after the petition is filed. At the hearing, §§ 635 and 636 allow continued detention for up to 15 judicial days only on grounds the statutes list, and the court can instead order home supervision, with or without electronic monitoring. A minor gets equal consideration for home supervision regardless of whether the minor lives in the county where the offense occurred.
The jurisdiction hearing. Also called an adjudication hearing, this is the trial stage, where the court hears evidence and decides whether the petition is sustained, meaning found true.
Disposition. Disposition is the court's decision about consequences. If the court declares the child a ward of the court, the court takes legal authority over the child's supervision. Options can include probation, meaning court-ordered supervision with conditions, along with community service, counseling or, in serious cases, secure confinement.
At each stage a juvenile defense attorney can make arguments on the minor's behalf.
When a Juvenile Assault Case Can Be Transferred to Adult Court
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. Under California law, transfer is not automatic: the court has to hear the evidence and make findings first.
In California, Welf. & Inst. Code § 707(a) allows the prosecutor to move for transfer only in two situations. The first is an offense alleged to have been committed when the minor was 16 or older, if it is an offense listed in § 707(b) or any other felony. The second is a § 707(b) offense committed at 14 or 15 by a person who was not apprehended before juvenile court jurisdiction ended. Section 707(b) lists specific serious offenses, and whether an assault allegation falls on that list depends on the offense charged and the facts alleged.
The motion must be made before jeopardy attaches, which roughly means before the trial stage begins. The court orders a probation report on the minor's behavioral patterns and social history, including any statement from the alleged victim. Here is the standard the statute sets:
"In order to find that the minor should be transferred to a court of criminal jurisdiction, the court shall find by clear and convincing evidence that the minor is not amenable to rehabilitation while under the jurisdiction of the juvenile court."
The court must weigh criteria the statute lists, including the degree of criminal sophistication the minor showed, and if it orders a transfer it must state its reasons on the record. A plea to the petition waits until the transfer hearing ends. If a case is transferred, it proceeds in adult court, where a finding of guilt is a criminal conviction with adult consequences.
For a family, this is often the most frightening possibility to hear named. An attorney for juvenile charges can contest a transfer motion at that hearing. These are California's rules; other states set their own transfer standards. The juvenile felony defense page covers transfer in felony cases more broadly.
A Minor's Rights When Questioned by Police
Minors have constitutional rights during police questioning, including the right to remain silent and the right to counsel. The United States Supreme Court held in In re Gault, 387 U.S. 1 (1967), that minors have due process rights in juvenile delinquency proceedings, including the right to counsel.
California adds its own rule. 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 phone or by video, and that consultation cannot be waived. When deciding whether a youth's statements can be used, the court must consider any failure to follow this rule and must consider a willful violation in judging the officer's credibility. The rule does not govern admissibility when the officer reasonably believed the information was needed to protect life or property from an imminent threat and the questions were limited to what was reasonably necessary to get it. It also does not require probation officers to follow it in their normal duties under §§ 625, 627.5 or 628.
A juvenile criminal defense attorney can challenge statements made without the required safeguards; how a court rules depends on the facts.
Parents often ask what happens "when someone presses charges." In juvenile court, a private person does not file the case. Law enforcement and intake, generally probation or the prosecutor, decide whether a petition is filed, and the alleged victim's report is one factor they consider. Time limits for filing also exist, and they depend on the offense and the state; this page does not cover each state's limits.
Possible Outcomes and Consequences of a Juvenile Assault Adjudication
Dispositions cover a wide range. The OJJDP case flow overview describes informal handling, probation orders that can include counseling, community or victim restitution or weekend confinement, and residential placement that may be secure or more home-like. Which applies depends on the state, the offense and the child's history.
California's Division of Juvenile Justice no longer operates. California law now provides for secure youth treatment facilities for the most serious cases, and this page does not describe their rules.
A juvenile case can also affect school discipline, college admissions and employment, and those consequences depend on the facts and on rules this page does not cover. Immigration consequences are governed by immigration law this page does not cover.
How Sealing a Juvenile Record Works
Sealing by petition under § 781 is also possible, five or more years after juvenile court jurisdiction ends or at any time after 18. The court orders sealing only if it finds that, since jurisdiction ended, the person has not been convicted of a felony or any misdemeanor involving moral turpitude, and that rehabilitation has been attained to the court's satisfaction. For a § 707(b) offense committed after turning 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; sealing varies by state. A juvenile defense attorney can explain which path, if any, a record may qualify for.
What a Juvenile Defense Attorney Does in an Assault Case
Defense counsel represents the minor at every stage: the detention hearing, any transfer hearing, the jurisdiction hearing and disposition. Counsel can challenge whether the petition was properly filed, whether the minor's rights were respected during questioning and whether the evidence supports the allegation.
At disposition, an attorney for a minor charged with a crime can present the child's background, school record and circumstances for the court to consider. In California, the probation report and the court's choices at disposition are where that information matters most.
In re Gault, 387 U.S. 1 (1967), recognized the right to counsel in juvenile delinquency proceedings, including appointed counsel when a family cannot afford to hire one. That right belongs to the child.
This page covers the general framework of juvenile assault cases in the United States. The rules that apply to a particular child's case depend on the state, the court, the facts alleged and the minor's history. State pages, such as the one on Texas juvenile defense, and the parent's guide to juvenile court explain how those rules shift.
Talking With an Attorney for Juvenile Charges
Facing a child's assault case often means trying to make sense of several questions at once, usually while worried and short on time: whether the child is detained, whether a transfer motion is possible and whether the record could later be sealed. A consultation with our juvenile defense attorney can cover the petition and the offense alleged, the hearing dates already set, whether the child is in custody or on home supervision, and the stage the case has reached. This page does not cover each state's specific rules or the facts of any one case.
