When a California teenager is accused of assault or battery, the case usually goes to juvenile court, not adult court. Assault means an unlawful attempt to injure someone, with the present ability to do it. Battery means actually using force on someone. The juvenile court decides whether the allegations are true and, if they are, what orders to make. The court does not impose an adult sentence.

Most parents facing this situation got a phone call from a school, a police station or juvenile hall, and are now trying to make sense of words like "petition" and "detention hearing" while worrying about their child's school and future. This page explains what an assault or battery charge means for a minor in California and how the juvenile court process works. It covers each stage from arrest to record sealing, using the terms the court itself will use.

What Assault and Battery Mean Under California Law

California defines the two offenses in separate statutes. Under Pen. Code § 240, "An assault is an unlawful attempt, coupled with a present ability, to commit a violent injury on the person of another." Under Pen. Code § 242, "A battery is any willful and unlawful use of force or violence upon the person of another."

The difference is contact. An assault can happen even if no one is touched, because the definition turns on the attempt and the ability to carry it out. A battery requires that force or violence was actually used on another person. Whether the facts meet either definition depends on what happened and on what the prosecution can prove.

Juvenile court uses its own language. Under Welf. & Inst. Code § 602, a minor between 12 and 17 years old, inclusive, who violates a California or federal criminal law is generally within the juvenile court's jurisdiction. That section allows exceptions under § 707, and it also covers some very serious offenses committed under 12. The case begins with a petition, a court filing that says what the state believes the child did. If the court finds the petition true, that finding is an adjudication, not a conviction. The court may then make the child a ward of the court, meaning the court takes on supervision of the child's conduct and care. The court's orders are a disposition, not a sentence.

A more serious charge, aggravated assault under Pen. Code § 245, is covered below.

How California Juvenile Court Handles Assault Charges

The case usually starts with temporary custody. Welf. & Inst. Code § 625 allows a peace officer to take a minor under 18 into temporary custody without a warrant when the officer has reasonable cause to believe the minor is described in § 602. The officer must tell the minor that anything the minor says can be used against them, and must advise the minor of constitutional rights, including the right to remain silent and the right to counsel.

Before police question the child in custody, another rule applies. Under Welf. & Inst. Code § 625.6, a youth 17 or younger "shall consult with legal counsel in person, by telephone, or by video conference" before a custodial interrogation and before any waiver of Miranda rights. The consultation cannot be waived. Section 625.6 has a narrow exception: it does not affect whether statements are admissible if the officer reasonably believed the information was needed to protect life or property from an imminent threat and asked only the questions reasonably needed to get it.

If the child is held, the clock matters. Under Welf. & Inst. Code § 631, a minor generally must be released within 48 hours, not counting nonjudicial days, unless a petition is filed within that time. Under Welf. & Inst. Code § 632, a detained minor must be brought before a judge or referee for a detention hearing before the end of the next judicial day after the petition is filed. That hearing decides whether the child stays in custody. Shorter limits apply to some nonviolent misdemeanors.

Detention Hearing, Petition and Diversion

At the detention hearing, release is the starting point. Under Welf. & Inst. Code § 635, the court must release the minor unless one of these applies:

  • the minor violated a juvenile court order;
  • the minor escaped from a juvenile court commitment;
  • detention is a matter of immediate and urgent necessity to protect the minor;
  • detention is reasonably necessary to protect another person or property; or
  • the minor is likely to flee.

The court may consider the circumstances and seriousness of the alleged offense alongside other factors. Under §§ 635 and 636, a minor must get equal consideration for release on home supervision regardless of whether the minor lives in the county where the offense occurred. Under § 636, a detention order may last up to 15 judicial days.

The petition itself is filed by the District Attorney or the Probation Department, according to the California Courts self-help guide. Not every case reaches that point. The Judicial Council's information for parents says a probation officer might offer a diversion program instead of court, and that each county has different rules and programs. Diversion means a program outside the usual court path. After a petition is filed, Welf. & Inst. Code § 654.2 lets the court, with the consent of the minor and parents, continue the hearing for six months while the minor completes a supervision program. The court must dismiss the petition if the minor successfully completes that program. Diversion is not available in every case and depends on the facts, the county and the court.

If the case goes forward, the jurisdiction hearing, the juvenile version of a trial, comes next. A judge decides it, and there is no jury. The District Attorney must prove the allegations beyond a reasonable doubt. If the petition is sustained, a disposition hearing follows. The court process overview walks through each of these steps in order.

Aggravated Assault and Assault with a Deadly Weapon in Juvenile Court

An assault charge becomes far more serious under Pen. Code § 245. Section 245(a)(1) covers assault with a deadly weapon or instrument other than a firearm. Section 245(a)(4) covers assault by any means of force likely to produce great bodily injury. Section 245(a)(2) covers assault with a firearm. For an adult, these offenses carry possible state prison terms. That alone sets them apart from simple assault, and the difference carries into how a juvenile court views the case. The aggravated assault page covers these charges in more depth.

The most significant difference involves transfer to adult court. Under Welf. & Inst. Code § 707(a), the prosecutor may move to transfer a case in only two situations:

  • the offense is alleged to have been committed when the minor was 16 or older, and it is either an offense listed in § 707(b) or any other felony; or
  • the offense is a § 707(b) offense committed at 14 or 15 by a person who was not apprehended before juvenile court jurisdiction ended.

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. The motion must be made before jeopardy attaches, and the court orders a probation report on the minor's behavioral patterns and social history. Whether a particular § 245 charge qualifies depends on the exact charge, the child's age and the court's findings. The difference between juvenile court and adult court is large, which is why a transfer motion is the most consequential point in a case like this.

Possible Outcomes: Probation, Diversion, and Other Dispositions

A sustained petition does not lead to one fixed result. Under Welf. & Inst. Code § 725(a), the court may, without making the minor a ward, place the minor on probation under the probation officer's supervision for up to six months. This option is limited to offenses other than those listed in § 654.3. If the minor does not comply, the court may then make the minor a ward. Under § 725(b), the court may instead make the minor a ward of the court.

On probation, the self-help guide explains, the probation officer enforces the court's orders, checks that the youth obeys the law and the probation terms, and works to involve the youth in school, community programs, job training or counseling. The OJJDP case flow overview describes probation orders that commonly add requirements such as counseling or restitution, and notes that case processing varies from community to community.

The judge may also decide the youth cannot live at home. The self-help guide describes three settings:

  • a group home, a privately run facility with therapeutic programs;
  • a county probation camp or ranch, where youth usually stay for a period of several months set by the court; and
  • a secure youth treatment facility, which is for youth found to have committed the most serious offenses. The court sets a specific commitment period and reviews the case periodically.

California's Division of Juvenile Justice no longer operates.

A juvenile case can also lead to consequences for school discipline, college admissions and employment. 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.

Sealing a Juvenile Assault Record in California

A juvenile record does not disappear at 18. California provides two main paths to sealing, and each one has conditions.

The first path follows from completing a program. Under Welf. & Inst. Code § 786, if a person satisfactorily completes a § 654.2 supervision program, probation under § 725, or a term of probation for any offense, the court shall dismiss the petition. The court must also seal the records held by the court, law enforcement, the probation department and the Department of Justice, and set a date for their destruction. There is an important exception in § 786(d). The court shall not seal or dismiss under § 786 if the petition was sustained for a § 707(b) offense committed at 14 or older, unless the finding on that offense was dismissed or was reduced to a misdemeanor or to a lesser offense not listed in § 707(b).

The second path is a petition to the court. Under Welf. & Inst. Code § 781, a person may ask the court to seal records five years or more after juvenile court jurisdiction ends, or at any time after turning 18. The court orders sealing only if it 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. If the case involved 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.

Which path applies depends on the offense, the child's age at the time and how the case ended.

What a Juvenile Defense Attorney Does in an Assault Case

At each stage, a juvenile defense attorney has a defined role. At the detention hearing, § 635 allows the court to hear evidence that the minor, a parent or counsel wishes to present. An attorney can present that evidence and argue for release or home supervision. At the jurisdiction hearing, the attorney can test whether the prosecution has proved each part of the definition, including the attempt, the present ability, and willful, unlawful force where battery is charged.

Diversion and disposition call for different work. The attorney can raise whether a supervision program under § 654.2 or a county program is possible. At disposition, the attorney can put the child's school record, family support and background in front of the court. If a transfer motion is filed under § 707, an attorney for a minor charged with a crime can contest the claim that the minor is not amenable to rehabilitation in juvenile court. After the case ends, the attorney can explain which sealing path under § 786 or § 781 the law provides.

None of these steps guarantees a result. What happens depends on the facts, the law and the court.

Talking With an Attorney for Juvenile Charges

An assault petition can raise several questions at once: whether the child stays detained, whether diversion is possible, whether a transfer motion could be filed, and whether the record can later be sealed. A consultation with our juvenile defense attorney can cover the petition and the charge it alleges, the hearing dates already set, whether the child is detained, and the stage the case has reached. This page does not cover adult criminal assault cases, civil restraining orders, or assault cases outside California. For weapons charges, a separate page explains how those cases proceed.
