When a teenager is accused of a serious felony, the case can begin in juvenile court and, in some circumstances, move to adult court. Each state's law decides which offenses count as serious. That label can shape whether the child is held in custody, whether the case can move to adult court, which outcomes the judge can order, and whether the record can later be sealed. The rules differ from state to state.
A parent or guardian may get a phone call they never expected. A son or daughter has been arrested or questioned, may be sitting in juvenile hall, and someone has used words like "felony," "violent" or "adult court." Those words land hard. The questions that follow are practical ones: what the charge means, what happens at the next hearing, and how much of the child's future depends on it. This page explains how the system handles these cases across the United States, using California's statutes as the worked example and naming each California rule as California's.
What 'Serious Juvenile Felony' Means
A juvenile case starts with a petition. This is the court document that lists what the minor is accused of doing. It is not a criminal complaint or an indictment. A minor is a person younger than the age limit that the state's juvenile court covers, and that limit differs by state.
"Serious felony" is not one national category. Each state writes its own definitions, and offenses on a serious or violent list in one state may be classified differently in another.
The words for each result also differ from adult court:
- Adjudication is the juvenile court's finding that the allegations are true. In California, a wardship order is not a conviction (Welf. & Inst. Code § 203).
- Disposition is the order the court makes after that finding. It is not a sentence.
In California, Welf. & Inst. Code § 602 provides that, except as provided in § 707, a minor between 12 and 17 years old, inclusive, who violates a law defining a crime is within the juvenile court's jurisdiction. Curfew ordinances based only on age are excluded. The court "may adjudge the minor to be a ward of the court." A ward of the court is a minor the court has taken under its supervision and authority. That is California's rule. For a fuller overview of each stage, see the juvenile court process.
How Juvenile Courts Classify Felony Offenses
A state may divide offenses into misdemeanors and felonies and may add a further tier, labeled "serious," "violent" or "aggravated," that triggers different procedures. Depending on the state, those procedures can include:
- eligibility for transfer to adult court
- hearings the court must hold
- longer commitment periods
California sets its list by statute. Welf. & Inst. Code § 707(b) lists 30 offenses. They include:
- murder
- certain arson offenses
- robbery
- rape with force, violence or threat of great bodily harm
- attempted murder
- assault with a firearm or destructive device
- assault by any means of force likely to produce great bodily injury
- carjacking while armed with a dangerous or deadly weapon
- voluntary manslaughter
That list matters in California both for transfer and, as covered below, for sealing.
Classification can also affect the possible outcomes. It can affect diversion, which is a process that can resolve a case without a formal adjudication. It can affect whether a transfer hearing is possible. It can also affect the range of dispositions, including probation, which is court-ordered supervision in the community under conditions the court sets. The classification is a starting point for these decisions, not the decision itself. For more, see the guide to juvenile felony defense.
The Juvenile Court Process for a Serious Felony Charge
Questioning can come before any hearing. In California, Welf. & Inst. Code § 625.6 provides that before a custodial interrogation, and before any waiver of Miranda rights, a youth 17 or younger "shall consult with legal counsel in person, by telephone, or by video conference." That consultation "may not be waived." There is a narrow exception. It applies when the officer reasonably believed the information was needed to protect life or property from an imminent threat, and the officer's questions were limited to what was reasonably necessary to get it. When a judge decides whether a youth's statements can be used, the judge considers any failure to comply. That is California's rule.
The detention hearing is where a judge or referee decides whether a minor in custody stays detained or goes home. Timing and grounds vary by state. In California, the timing works this way:
- Under Welf. & Inst. Code § 631, a minor in custody generally must be released within 48 hours, not counting nonjudicial days, unless a petition or a criminal complaint is filed within that time. For a minor taken into custody without a warrant on the belief that the minor committed a misdemeanor that does not involve violence, the threat of violence, or possession or use of a weapon, and who is not currently on probation or parole, § 631(b) instead requires both a filed petition and a detention order under § 635.
- Under Welf. & Inst. Code § 632, a detained minor generally must be brought before the court before the end of the next judicial day after the petition is filed. If that does not happen, the minor must be released. For the same kind of nonviolent misdemeanor arrest without a warrant, § 632(b) requires the detention hearing as soon as possible, but no later than 48 hours after the minor was taken into custody, excluding nonjudicial days, after a petition has been filed.
The jurisdiction hearing (also called an adjudication hearing) is where the court decides whether the allegations in the petition are true. Who decides varies by state. If the court sustains the petition, meaning it finds the allegations true, a disposition hearing follows. For the most serious charges, a transfer hearing may come first.
Transfer to Adult Court: When It Can Happen and How
A transfer hearing is the proceeding where a court decides whether a minor's case should be handled in adult criminal court instead of juvenile court. Depending on the state, it may be called a fitness hearing or a waiver hearing. An overview of what being tried as an adult involves is available separately. States in the United States use different ways to move a case to adult court, and they vary a great deal:
- Judicial waiver: a judge decides after a hearing.
- Prosecutorial direct file: in some states, a prosecutor can file the case directly in adult court.
- Statutory exclusion: in some states, the legislature removes certain offenses from juvenile court jurisdiction altogether.
The minimum age for transfer also differs by state. For a judicial waiver, transfer is generally not automatic, and a hearing and findings are required. The page on juvenile transfer describes these mechanisms in more depth.
Two United States Supreme Court decisions bear on these proceedings. Kent v. United States, 383 U.S. 541 (1966), arose under the District of Columbia's Juvenile Court Act. The Court held that, as a condition to a valid waiver order, the minor was entitled to a hearing, including access by counsel to the social records and probation or similar reports the court considers, and to a statement of reasons for the court's decision, a result it said was required by the statute read in the context of constitutional principles relating to due process and the assistance of counsel. In re Gault, 387 U.S. 1 (1967), concerned proceedings to determine delinquency which may result in commitment to an institution in which the juvenile's freedom is curtailed. For those proceedings the Court held that the Due Process Clause of the Fourteenth Amendment requires notice of the charges and of the right to counsel, retained or, if the family cannot afford counsel, appointed, and that the privilege against self-incrimination applies to juveniles as it does to adults.
California's process works through Welf. & Inst. Code § 707, and it begins with a motion by the prosecutor. Two groups can be the subject of that motion:
- a minor who was 16 or older at the time of a § 707(b) offense or any other felony
- a person who was 14 or 15 at the time of a § 707(b) offense but was not caught 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. That report includes any statement the victim offers. The court must consider criteria listed in the statute, including the degree of criminal sophistication the minor showed.
To order a transfer, the court must find by clear and convincing evidence that the minor is not amenable to rehabilitation while under juvenile court jurisdiction. If the court orders a transfer, it must recite the basis for its decision in an order entered upon the minutes, including the reasons supporting its finding that the minor is not amenable to rehabilitation while under the jurisdiction of the juvenile court. A transferred case is handled in a court of criminal jurisdiction. How these proceedings unfold step by step is covered on the page about transfer hearings.
Dispositions for Serious Felonies: What the Court Can Order
Disposition is the juvenile court's counterpart to sentencing, though juvenile court does not call it a sentence. Possible dispositions range widely, and the options and the names of facilities differ by state:
- informal probation
- formal probation
- placement in a group home or foster care
- commitment to a county juvenile facility
- commitment to a state-level secure youth facility
In California, Welf. & Inst. Code § 725.5 provides that in determining the judgment and order to be made once a minor is found to be a person described in § 602, the court shall consider, in addition to other relevant and material evidence:
- the age of the minor
- the circumstances and gravity of the offense committed by the minor
- the minor's previous delinquent history
California's Division of Juvenile Justice no longer operates. Older descriptions of commitments to it are out of date, and the placements available today depend on current California statutes and the court's findings.
There is no single national answer to how long a child can be held. Each state's law governs how long a commitment can last, and the answer depends on the offense, the minor's age and the order the court makes. Those charged with violent offenses may also want to read about juvenile assault charges.
Record Sealing and Long-Term Consequences
Sealing is a court order that restricts access to a juvenile record. It does not erase the record, and the record does not simply disappear. Whether a record can be sealed depends on the offense, the minor's age and the state's statute. In California, the sealing rules are tighter for an offense listed in § 707(b) that was committed at 14 or older, as described below.
In California, Welf. & Inst. Code § 786 provides that when a person satisfactorily completes informal supervision under § 654.2, probation under § 725, or a term of probation for any offense, "the court shall order the petition dismissed" and the related records sealed. "Satisfactorily" is defined in § 786(c): no new finding of wardship and no conviction for a felony offense or a misdemeanor involving moral turpitude during the period of supervision or probation, and no failure to substantially comply with the reasonable orders of supervision or probation that are within the person's capacity to perform. Unpaid restitution alone does not count against the person. The court also seals records when a petition is dismissed or not sustained.
There is an important limit. Under § 786, a petition sustained for a § 707(b) offense committed at 14 or older cannot be sealed unless that finding was dismissed or reduced to a misdemeanor or to a lesser offense not on that list.
Welf. & Inst. Code § 781 offers another route. The person, or the county probation officer, may petition for sealing five years after juvenile court jurisdiction ends, or at any time after the person turns 18. The court must find that the person has not been convicted of a felony or of a misdemeanor involving moral turpitude since the case ended, and that rehabilitation has been attained to the court's satisfaction.
For a § 707(b) offense committed after age 14 that ended in wardship, § 781 sets added conditions. A petition may be filed or considered only if the person was not committed to the Division of Juvenile Facilities, is at least 18 and has completed any probation supervision related to that offense, or was so committed, is at least 21 and has completed probation supervision after release. Those conditions do not apply if the offense was dismissed or reduced to a misdemeanor by the court. Even after sealing, prosecutors and courts can still access those records in certain later proceedings, including a later transfer motion.
California's sealing statutes also touch firearms and registration:
- Section 786 refers to sustained petitions that make a person ineligible to own or possess a firearm until age 30 under California law.
- Section 781 provides that, when the juvenile records of a ward subject to the registration requirements of Penal Code § 290 are sealed, the order also relieves the person from the registration requirement. A record of a § 707(b) offense committed after age 14 for which the person is required to register under Penal Code § 290.008 shall not be sealed.
None of this is automatic at 18. School discipline consequences can follow a juvenile case and depend on the facts and on rules this page does not cover. Immigration consequences are governed by immigration law this page does not cover. The page on juvenile sex crimes addresses registration-related offenses in more depth.
How Juvenile Law Varies Across States
Age is the clearest example of how much states differ. The upper age limit, meaning the age at which a person is treated as an adult by default, varies.
Minimum ages vary too. California's § 602 generally starts at 12. It reaches younger children only for the specific offenses § 602(b) lists, covered in the FAQ below.
Several other rules differ by state:
- Transfer: the mechanisms and the offenses that make a minor eligible for transfer differ significantly.
- Diversion: whether it is available for a serious felony varies by state, and even by county within a state.
- Sealing: who can seek it, when, and for which offenses varies by state.
For a parent reading late at night, this variation is the frustrating part. A rule a friend describes from another state may not apply at all. The California rules on this page are California's alone, and another state's courts may handle the same charge very differently. A broader overview of juvenile crimes covers more offense types.
If You'd Like to Talk Through Your Child's Case
A serious felony petition brings several decisions close together. These include the detention hearing, a possible transfer motion, and later questions about disposition and sealing. This page explains how the system works in general. It does not cover any one child's facts or every state's rules.
