California Juvenile Laws and Rules: Court Process, Rights, and Records

California juvenile laws govern how the state responds when someone between 12 and 17 breaks a criminal law, and the framework looks different from adult court at every step: no jury, a judge focused on rehabilitation as much as accountability, stronger protections during police questioning, and pathways to seal records that adult defendants don’t get. The rules live primarily in the Welfare and Institutions Code, and they’ve shifted significantly in recent years, including a minimum age for delinquency jurisdiction and the closure of California’s state-run youth prisons in favor of county-operated facilities.

Who the Juvenile System Covers

California’s juvenile court has jurisdiction over minors who are 12 to 17 years old when they violate a state or federal law or a local criminal ordinance. Curfew ordinances based solely on age are handled separately and don’t trigger delinquency jurisdiction on their own.¹

The floor of 12 is relatively new. Before SB 439, California had no minimum age, and very young children could be adjudicated as wards. Now, children under 12 can only be brought into juvenile court for a narrow set of extremely serious offenses, including murder and certain violent sexual offenses.¹

How Long Jurisdiction Lasts

Juvenile court involvement doesn’t automatically end at 18. For most offenses, the court can retain jurisdiction until age 21. For serious offenses listed in WIC 707(b), that extends to age 23 or two years from the date of commitment to a secure youth treatment facility, whichever is later. In cases where an adult conviction would have carried an aggregate sentence of seven years or more, jurisdiction can run until age 25, with limited authority to extend further in some 707(b) cases.²

Status Offenses Versus Delinquency Offenses

California sorts juvenile conduct into two categories, and the sorting shapes how heavy the response can be.

Status offenses are acts that are only unlawful because the person is a minor. Habitual truancy is the classic example. Persistent refusal to obey a parent’s reasonable directions, or being beyond parental control, also falls here. The court’s power in status cases is deliberately limited. A minor adjudicated solely for truancy cannot be placed in a locked facility or removed from parental custody except to ensure school attendance.³

Delinquency offenses are acts that would be crimes at any age. They run from petty theft and vandalism through robbery, arson, and murder. Less serious offenses often resolve through informal probation or diversion. Serious offenses listed in WIC 707(b) can trigger formal adjudication, extended jurisdiction, and commitment to a secure facility.⁴

How a Juvenile Case Moves Through Court

The terminology shifts in juvenile court. There is no arraignment, no trial, no sentencing. Instead, there are three stages, and each one has its own function.

Detention Hearing

When a minor is taken into custody, the officer or probation department decides whether to release the minor to a parent with a citation or hold the minor in a juvenile facility. If the minor is held, a detention hearing must occur as soon as possible, and no later than 48 hours after custody begins, excluding non-court days.⁵

At that hearing, the minor and parent or guardian are told the reasons for custody, the nature of the proceedings, and the minor’s right to counsel at every stage.⁶

Adjudication Hearing

Adjudication is the juvenile equivalent of a trial. A judge, not a jury, weighs the evidence and decides whether the minor committed the alleged offense. The standard of proof matches adult court: beyond a reasonable doubt. The single-judge format is less adversarial in feel, but the consequences of a sustained petition can be substantial, and judges scrutinize the evidence carefully.

Disposition

If the petition is sustained, the case moves to disposition. The judge reviews reports from probation and, when appropriate, from social workers and mental health professionals, then crafts an individualized plan. That plan might include informal or formal probation, community service, counseling, substance abuse treatment, group home placement, or commitment to a secure youth treatment facility. The court weighs the offense, the minor’s history, family circumstances, and any prior involvement with the system.

When a Minor Can Be Sent to Adult Court

Proposition 57, passed by California voters in 2016, took away the district attorney’s ability to file charges against a minor directly in adult court. A minor now cannot be tried as an adult unless a juvenile court judge orders transfer after a hearing. Only the prosecutor can request that hearing, and only in specific circumstances: minors 16 or older accused of any felony, or minors 14 or 15 accused of a serious offense listed in WIC 707(b).⁴

The 707(b) list includes murder, attempted murder, arson of an inhabited structure, robbery, kidnapping, and certain violent sexual offenses. It’s the same list that governs extended jurisdiction and eligibility for secure facility commitment.⁴

To order transfer, the judge must find by clear and convincing evidence that the minor cannot be rehabilitated within the juvenile court’s jurisdiction. Five factors guide the analysis:

Criminal sophistication, including age, maturity, intellectual capacity, peer or family pressure, childhood trauma, and foster care involvement.
Whether the minor can realistically be rehabilitated before juvenile jurisdiction expires.
The seriousness of prior delinquent history and the role environment and trauma played in it.
Whether prior rehabilitation efforts actually provided adequate services and how the minor responded.
The circumstances of the current offense, including the minor’s mental state, degree of involvement, and the harm caused.⁴

Each factor pulls the court toward considering mitigation, and transfer is meant to be the exception rather than the default.

Rights That Apply to Minors

Juvenile proceedings can end in confinement, and constitutional protections apply. The U.S. Supreme Court settled that in In re Gault, holding that minors facing delinquency proceedings have the right to notice of charges, counsel, protection against self-incrimination, and confrontation of witnesses.⁷

The Right to an Attorney

California goes beyond the federal minimum. If a minor accused of a status or delinquency offense appears at a hearing without an attorney, the court must appoint one, regardless of the family’s ability to pay. The court can only proceed without appointed counsel if the minor makes an intelligent waiver, and judges are skeptical of waivers coming from young people.⁸

If a conflict exists between the minor and a parent or guardian, the court must appoint separate counsel for each. This comes up more often than families expect, particularly when a parent is pressuring the child toward a specific outcome that doesn’t serve the child’s legal interests.⁸

Attorney Consultation Before Police Questioning

This one matters enormously and often surprises parents. Under WIC 625.6, before a youth 17 or younger can be subjected to custodial interrogation, and before that youth can waive Miranda rights, the minor must first consult with an attorney. The consultation can happen in person, by phone, or by video. It cannot be waived.⁹

A narrow emergency exception exists when an officer reasonably believes the information is needed to protect life or property from an imminent threat, and the questioning stays limited to that threat. Outside that exception, failure to comply gives the defense strong grounds to suppress any statements the minor made.⁹

Parents in the Process

Parents and guardians are notified of every proceeding and encouraged to take part. Family involvement is treated as a component of rehabilitation, and disposition plans often include obligations for the family as well as the minor.

What the Court Can Order at Disposition

The range of possible outcomes is wide by design, letting judges match the response to the offense and the individual.

Probation and Community-Based Conditions

For first-time and less serious offenses, informal probation, formal probation, community service, counseling, and educational workshops are the common outcomes. Judges can also impose curfews, stay-away orders, and regular check-ins with a probation officer. The point is to hold the minor accountable while keeping them in the community.

Victim Restitution

When a victim has an economic loss, the court must order the minor to pay restitution. It’s mandatory, not discretionary. The court orders full restitution unless it finds compelling and extraordinary reasons not to, stated on the record. If the loss can’t be calculated at disposition, the order stays open and the amount is set later.¹⁰

Secure Youth Treatment Facilities

For the most serious cases, California now uses county-operated Secure Youth Treatment Facilities. The state’s Division of Juvenile Justice ceased operations on June 30, 2023, and transferred its remaining population to counties under the realignment mandated by SB 823.¹¹

Commitment to a secure youth treatment facility is reserved for wards 14 or older who have been adjudicated for a 707(b) offense. Before ordering it, the court must find on the record that no less restrictive option is suitable, weighing the severity of the offense, the minor’s history, the facility’s programming, and the minor’s developmental maturity and mental health.¹²

The court sets a baseline term of confinement tied to the most serious adjudicated offense, and the maximum confinement cannot exceed the middle-term adult prison sentence for the same crime. For most 707(b) offenses, confinement caps at age 23. For cases where an adult sentence would have been seven years or more, it caps at age 25.¹²

Diversion Instead of Adjudication

For many offenses, formal adjudication is treated as a last resort. Diversion programs combine counseling, workshops, community service, and accountability measures suited to the minor’s circumstances. Complete the program, and the case is dismissed with no sustained petition and no wardship.

Sealing Juvenile Records

Juvenile proceedings are generally closed to the public, and California provides two distinct routes to seal records once a case is over. This is one area where the juvenile system offers a real second chance that adult court doesn’t.

Automatic Sealing After Successful Probation

If a minor satisfactorily completes informal supervision, probation, or formal probation, the court must dismiss the petition and order the records sealed. It happens automatically, without a separate petition. The order reaches records held by the juvenile court, law enforcement, probation, and the Department of Justice.¹³

“Satisfactory completion” means no new wardship findings or convictions for a felony or a misdemeanor involving dishonesty during supervision, and substantial compliance with the court’s reasonable orders. Unpaid restitution doesn’t block sealing; the court can convert it to a civil judgment. Once records are sealed under this provision, the arrest and proceedings are legally deemed never to have occurred, and the person can truthfully say they were never arrested or involved in a juvenile case.¹³

One important boundary: automatic sealing is not available if the sustained petition was based on a 707(b) offense committed at 14 or older.¹³

Petition-Based Sealing Under WIC 781

Cases that don’t qualify for automatic sealing, including 707(b) offenses, can still be sealed by petition. Eligibility opens at age 18, or five years after probation ended or the last contact with a probation officer, whichever comes first. The court holds a hearing and looks at whether the person has been rehabilitated, generally meaning no felony convictions and no misdemeanor convictions involving dishonesty since the case closed. Probation investigates, gathers records from every agency involved, and recommends for or against sealing. If the court is satisfied, it orders the records sealed and eventually destroyed.¹⁴

Constitutional Ceilings on Juvenile Punishment

Federal constitutional law sets outer limits that California must respect. The U.S. Supreme Court has read the Eighth Amendment’s ban on cruel and unusual punishment to create special protections for minors, recognizing that immaturity, susceptibility to outside pressure, and still-developing character make children different from adults for sentencing purposes.

The death penalty is unconstitutional for anyone who committed the crime before turning 18. Life without the possibility of parole is unconstitutional for a juvenile convicted of a non-homicide offense. Even for homicide, no state can impose a mandatory life-without-parole sentence on a juvenile; the sentencing court must be free to consider the offender’s youth and individual circumstances before imposing the harshest available punishment.¹⁵

These decisions shape California’s approach at every level: baseline confinement terms tied to adult middle terms, individualized rehabilitation plans, and the mandatory judicial review of any transfer to adult court all reflect the constitutional command that youth counts as a mitigating factor.
