When a teenager is accused of aggravated assault, it usually means an assault alleged to involve a weapon or force likely to cause serious injury. The case generally starts in juvenile court, not adult court, and moves through a detention decision, hearings and a disposition. Whether it can move to adult court, and whether the record can later be sealed, depends on the child's age, the offense and state law.

Most parents facing this charge are dealing with a phone call from police or juvenile hall, a word on a form they have never seen before, and a child who may not be home tonight. They want to know what the charge actually means, who decides whether their son or daughter stays in custody, whether "adult court" is a real possibility, and what this will mean for school and the years after. This page walks through each of those questions, using California's statutes as the worked example and noting where other states differ.

What Aggravated Assault Means When a Minor Is Charged

Aggravated assault is a general label, not always a statute's name, for an assault alleged to be more serious than a simple assault because of a weapon, the risk of serious injury, or another aggravating fact. Simple assault involves no such factor.

In California, the closest offense is Pen. Code § 245. Its core subdivisions cover "an assault upon the person of another with a deadly weapon or instrument other than a firearm," an assault with a firearm, and an assault "by any means of force likely to produce great bodily injury." Other subdivisions cover assault with specific types of firearms and assault on a peace officer or firefighter. The statute states punishment in adult terms, ranging across state prison, county jail or a fine depending on the subdivision, but those ranges describe adult court. For more on lesser charges, see California's juvenile assault and battery rules.

California's juvenile court generally covers minors who were 12 through 17 when the alleged law violation happened, and under 12 only for the listed offenses in Welf. & Inst. Code § 602, which are murder and specified forcible sex offenses. Section 602 makes these rules subject to § 707, the transfer statute discussed below. The case begins with a petition: the document that starts a juvenile case and states the allegations. It is not called a criminal complaint. The ages a juvenile court covers and how a case begins differ by state, so California's rule is not everyone's rule. A juvenile defense attorney is the lawyer who handles this kind of case in juvenile court.

How a Juvenile Aggravated Assault Case Moves Through Court

Police questioning often comes first, and California sets a specific rule for it. 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 shall consult with legal counsel in person, by telephone, or by video conference. The consultation may not be waived." The court considers any failure to follow this rule when deciding whether the youth's statements can be used. The rule does not apply where the officer reasonably believed the information was needed to protect life or property from an imminent threat and limited questions to what was reasonably necessary, and it does not apply to probation officers performing duties under §§ 625, 627.5 or 628.

After an arrest in California, the minor is delivered to a probation officer. Under Welf. & Inst. Code § 628, that officer must immediately investigate and immediately release the minor to a parent, guardian or responsible relative, unless the evidence shows that staying home is contrary to the minor's welfare and one or more of the conditions discussed in the next section exists.

A minor kept in custody must generally be released within 48 hours, excluding nonjudicial days, unless a petition has been filed within that time (Welf. & Inst. Code § 631). Once a petition is filed, § 632 requires that the minor be brought before a juvenile court judge or referee "as soon as possible but in any event before the expiration of the next judicial day" for a detention hearing, the hearing at which the court decides whether the minor stays in custody. A minor not brought before the court in time must be released. Shorter timing rules in §§ 631(b) and 632(b) apply only to nonviolent misdemeanors without a weapon, which generally would not describe an aggravated assault allegation.

Some cases are resolved through diversion, a process that may resolve a case without a sustained petition. Whether it is available depends on the offense, the minor's history and local practice. Otherwise the case goes to a jurisdiction hearing, also called an adjudication hearing: the juvenile court's version of a trial, where the judge decides whether the allegations are proven. If they are, the petition is "sustained," which is not called a conviction.

Next comes disposition, the court's decision about consequences after a petition is sustained. It serves the purpose sentencing serves in adult court, but it is not called a sentence. The court may make the minor a ward of the court, meaning the child is placed under the court's ongoing supervision, and may order probation, a period of supervision with conditions the minor must meet. The federal juvenile justice case flow describes this sequence nationally and notes that each state's processing is unique. Timelines and procedures differ by state; New York's Family Court process is one example of a different system.

Detention: What Keeps a Minor Held and What Can Lead to Release

The first decision to hold a child is made by the probation officer under § 628, and the juvenile court then decides at the detention hearing whether the minor stays held or goes home. Police do not make that final call.

California's Welf. & Inst. Code § 635 directs the court to release the minor unless it appears that the minor:

  • has violated an order of the juvenile court;
  • has escaped from a commitment of the juvenile court;
  • must be detained as a matter of immediate and urgent necessity for the minor's protection, or as reasonably necessary to protect the person or property of another; or
  • is likely to flee to avoid the court's jurisdiction.

The court may consider the circumstances and gravity of the alleged offense together with other factors, which matters in an aggravated assault case. The court must also release the minor unless a prima facie showing has been made that the minor falls under § 601 or § 602. Under § 636, if a ground exists and remaining at home is contrary to the minor's welfare, the court may order detention for up to 15 judicial days and must enter findings of fact supporting the order.

The alternative to detention is home supervision: release home under conditions set by the court, which may include electronic monitoring. Sections 635(b)(2) and 636 require that a minor be given equal consideration for release on home supervision regardless of whether the minor lives in the county where the offense occurred, and the decision to detain may not rest solely on county of residence. That rule concerns where the child lives; it is not a general preference for home supervision. Detention standards and timelines vary by state, and Illinois, for example, sets its own Illinois detention hearing rules.

Transfer to Adult Court: When It Can Happen and What It Requires

The words "tried as an adult" are often the most frightening part of an aggravated assault charge, so the conditions matter. In California, a case moves to adult court only after a transfer hearing: a proceeding in which the juvenile court decides whether the case should leave juvenile court for a court of criminal jurisdiction.

Under Welf. & Inst. Code § 707(a), the prosecutor may move to transfer only in two situations: when the offense is alleged to have been committed when the minor was 16 or older and is either an offense listed in § 707(b) or any other felony; or when a § 707(b) offense is alleged to have been committed at 14 or 15 by a person who was not apprehended before the end of juvenile court jurisdiction. The motion must be made before jeopardy attaches, and the court orders probation to prepare a report on the minor's behavioral patterns and social history, including any statement from the alleged victim.

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, considering criteria the statute lists. Whether a particular § 245 allegation is a § 707(b) offense, or is charged as a felony, depends on the facts alleged and the statute's text. That determination affects transfer eligibility at 14 and 15, and sealing as well.

Transfer rules, including ages, offenses and standards, differ significantly by state. Some states, as the federal case flow page notes, let prosecutors file certain cases directly in criminal court. A juvenile defense attorney for aggravated assault charges can explain how a state's transfer rules apply in a given case.

Disposition Options After a Petition Is Sustained

Disposition options in an aggravated assault case can include supervision without wardship, probation with conditions, placement outside the home, or confinement, depending on the offense, the minor's history and the court's findings. Nationally, the federal case flow page describes probation orders that may include counseling, restitution and weekend confinement, along with residential placements that range from secure to home-like settings.

California's Division of Juvenile Justice no longer operates. An older reference to commitment there does not describe a current option. Which disposition a California court may order in a specific case depends on the statute governing the offense and the court's findings. The court decides at the disposition hearing after reviewing the probation report and hearing from both sides.

Parents also worry about school, college, jobs and immigration status, often as much as the court case itself. Consequences in these areas can follow a juvenile case, and they depend on the facts and on rules this page does not cover. Immigration consequences are governed by immigration law this page does not cover. A sustained petition is not a conviction, but that difference does not settle every question outside juvenile court.

Sealing a Juvenile Record After an Aggravated Assault Case

California offers two main routes to sealing, a court order that closes a juvenile record so that, for most purposes, the case is treated as though it did not occur. A record does not disappear or erase itself, and it is not sealed automatically at 18.

Under Welf. & Inst. Code § 786, when a person satisfactorily completes an informal program of supervision, probation under § 725, or a term of probation for any offense, the court shall dismiss the petition and seal the records. Under § 786(d), however, the court shall not seal a record or dismiss a petition under § 786 if the petition was sustained based on an offense listed in § 707(b) committed when the individual was 14 or older, unless the finding on that offense was dismissed or reduced to a misdemeanor or to a lesser offense not listed in § 707(b). Once a petition is dismissed, the arrest and proceedings are deemed not to have occurred, and the person may answer inquiries from employers and schools accordingly.

Under § 781, a person may petition for sealing five years or more after juvenile court jurisdiction ends, or at any time after turning 18. The court orders sealing only if it finds that, since jurisdiction ended, the person has not been convicted of a felony or of any misdemeanor involving moral turpitude, and that 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.

Because some § 245 allegations may fall within § 707(b), both of these limits can shape an aggravated assault case. Sealing rules differ by state; the general juvenile assault charges page describes how the process compares across states.

What to Look for in a Juvenile Defense Attorney for Aggravated Assault Charges

Aggravated assault is among the more serious charges a minor can face in juvenile court. Detention, possible transfer, disposition and later sealing are all at stake, which is why early involvement of a juvenile criminal defense attorney matters. In California, § 625.6 already requires a lawyer consultation before custodial questioning of anyone 17 or younger.

A juvenile defense attorney handles the detention hearing, the jurisdiction hearing, any transfer hearing and the disposition. Each stage has its own legal standard and timing: § 635's detention grounds, the clear and convincing evidence standard in § 707, and the sealing limits in §§ 781 and 786. An attorney for a minor charged with a crime works within the terms and deadlines of the state where the case is pending. California's process is set out in more detail in the California juvenile defense overview.

This page covers the general framework of how juvenile aggravated assault cases work. It does not cover every state's rules, local court procedures, or the specific facts of any individual case.

Talking With a Juvenile Defense Attorney About an Aggravated Assault Charge

An aggravated assault petition raises several questions at once: whether the alleged offense is one § 707(b) lists, whether transfer is possible at the child's age, and how the eventual finding affects sealing. A consultation with our juvenile defense attorney can cover the petition and the specific subdivision charged, the dates of the detention or jurisdiction hearing, whether the child is detained or on home supervision, and the stage the case has reached. This page does not address any individual case's facts or local court practice.
