Juvenile Court vs. Adult Court: How the Two Systems Work

If your child has been arrested or charged, the case usually starts in juvenile court. Juvenile court is a separate system built around a minor's rehabilitation, not punishment. It uses different words: a petition instead of a criminal complaint, an adjudication instead of a conviction, a disposition instead of a sentence. Its hearings are generally closed and its records generally confidential.

Most people facing a child's arrest have only ever seen adult court, on television or in the news, so they picture handcuffs, a jury and a prison term. The juvenile system works differently at almost every step, and some cases can still move to adult court. This page explains how the two systems differ. Rules vary from state to state, so where a specific rule is given, it is California's rule, and the page says so.

What Juvenile Court Is and How It Differs from Adult Criminal Court

Juvenile court is a specialized court for cases involving young people accused of breaking the law. The upper and lower age limits vary by state. Adult criminal court is built around punishment, deterrence and public accountability. Juvenile court is built around rehabilitation and the child's welfare.

That difference in purpose shows up in the vocabulary. A petition is the document that formally starts a juvenile case and states the allegations. It takes the place of a criminal complaint or indictment. An adjudication is the court's finding that the allegations are true, the juvenile counterpart to a conviction. A disposition is the outcome the court orders afterward, the counterpart to a sentence. A ward of the court is a minor the court has placed under its ongoing supervision. The federal Office of Juvenile Justice and Delinquency Prevention notes that this language differs from the criminal court system, where a person is convicted and sentenced. This page uses the juvenile terms throughout.

Two other structural differences matter. Juvenile hearings are generally closed to the public, while adult criminal proceedings are generally open. Juvenile records are generally confidential, while adult criminal records are generally public. The same federal page cautions that each state's processing is unique and that practice varies even within a state. A broader overview appears in this site's parent's guide to juvenile court.

Age Jurisdiction: Who Juvenile Court Covers

Age decides which court hears a case. Juvenile court jurisdiction, meaning the court's legal power over a case, covers a range of ages that each state sets for itself, and both the upper and lower limits differ from state to state.

The words "minor" and "juvenile" overlap but are not identical. A minor is generally a person under the age of majority, usually 18. A juvenile, in the court sense, is a person within the age range that a state's juvenile court covers. A state's statutes define both terms, and the definitions do not always match.

California's rule is set out in Welf. & Inst. Code § 602. Except as provided in § 707, a minor who is between 12 and 17 years of age, inclusive, when he or she violates a state or federal law, or a city or county ordinance defining a crime, is within the juvenile court's jurisdiction. Curfew ordinances based solely on age are excluded. The court may adjudge that minor a ward of the court. A minor under 12 is within the juvenile court's jurisdiction only when alleged to have committed one of the offenses § 602(b) lists:

• murder;
• rape by force, violence, duress, menace, or fear of immediate and unlawful bodily injury;
• sodomy by those same means;
• oral copulation by those same means; and
• sexual penetration by those same means.

The statute ties jurisdiction to the minor's age when the offense was committed, not to the minor's age at the time of the hearing.

How a Juvenile Case Moves Through Court: From Arrest to Disposition

Many juvenile cases begin with the police. Federal regulations described by the OJJDP case flow overview discourage holding juveniles in adult jails and lockups. At arrest, the case may be diverted or referred onward, often to a juvenile probation department. That referral step has no real adult-court counterpart.

The next question is detention, meaning whether the child stays in custody while the case is pending. Adult court usually turns on bail. Juvenile court instead asks whether holding the child is necessary.

California's detention rules work as follows:

• Probation officer's decision. Under Welf. & Inst. Code § 628, the probation officer must immediately release the minor to a parent, guardian or responsible relative. The officer may hold the minor only if staying home is contrary to the minor's welfare and at least one listed condition exists: urgent protection of the minor or others is necessary, the minor is likely to flee, or the minor has violated a juvenile court order.
• 48-hour release rule. Under § 631, the minor generally must be released within 48 hours, excluding nonjudicial days, unless a petition or a criminal complaint is filed within that time.
• Detention hearing. Under § 632, a detained minor generally must appear before a judge or referee for a detention hearing before the end of the next judicial day after the petition is filed. A different 48-hour rule (excluding nonjudicial days) applies to certain warrantless arrests of minors not on probation or parole for misdemeanors not involving violence, a threat of violence, or possession or use of weapons. A minor not brought before the court in time must be released.
• Court's decision. Sections 635 and 636 set the grounds on which the court may keep a minor detained. If those grounds are met, § 636 allows detention for up to 15 judicial days. Both sections require that a minor receive equal consideration for release on home supervision, regardless of whether the minor lives in the county where the offense occurred.

After the petition comes the adjudication hearing, which California calls a jurisdiction hearing. A judge usually hears it. Then comes the disposition hearing, where the court decides on outcomes such as probation or residential placement. Diversion resolves a case without a formal adjudication, often through an informal agreement and set conditions. In adult court, the comparable steps are arraignment, a preliminary hearing or grand jury, a public trial and sentencing, and they produce a criminal record. Each step is laid out in this site's guide to the juvenile court process and the California juvenile court process.

Rights in Juvenile Court: What the Constitution Guarantees — and What It Does Not

The United States Supreme Court decided the central questions about juvenile rights in three cases. In In re Gault, 387 U.S. 1 (1967), the Court held that juveniles in delinquency proceedings that could end in confinement have several rights: notice of the charges, counsel, protection against self-incrimination, and the right to confront and cross-examine witnesses.

In In re Winship, 397 U.S. 358 (1970), the Court held that the allegations in a delinquency case must be proved beyond a reasonable doubt, the same standard adult court uses. In McKeiver v. Pennsylvania, 403 U.S. 528 (1971), the Court held that the Constitution does not require a jury trial in juvenile delinquency proceedings. Federal materials note that in some states the youth is still given a right to a jury trial. Adult defendants have the jury right as a constitutional matter.

California adds its own protection during police questioning. Welf. & Inst. Code § 625.6 provides that 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 statute has two exceptions:

• It does not govern whether statements are admissible when the officer reasonably believed the information was necessary to protect life or property from an imminent threat and limited the questions to that purpose.
• It does not apply to a probation officer's normal duties under §§ 625, 627.5 or 628.

Closed hearings belong to how the juvenile system is built. They are not a constitutional right of the child.

Transfer to Adult Court: When a Juvenile Case Moves

For a parent, transfer is often the deepest fear, so it helps to see how narrow California's version is. Transfer, also called waiver or certification, is the process that moves a case from juvenile court to adult criminal court.

States use different methods. In judicial waiver, a juvenile judge decides at a transfer hearing. The OJJDP overview also notes that prosecutors may file some cases in either juvenile or criminal court. In many states, prosecutors must file certain serious cases in criminal court. In a growing number of states, prosecutors may choose juvenile or adult court for a defined list of cases. Not every state uses every method.

California uses judicial waiver. Under Welf. & Inst. Code § 707(a), a 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 alleged at age 14 or 15, and the person was not apprehended before juvenile court jurisdiction ended.

The court orders a probation report on the minor's behavioral patterns and social history. It may order 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. In making that decision, the court considers the criteria the statute lists, including the minor's degree of criminal sophistication. More detail appears in this site's guide to California juvenile transfer.

A transferred case is public. A conviction in adult court brings an adult sentence and a public adult criminal record.

Juvenile Records: Confidentiality, Sealing, and Collateral Consequences

A juvenile record does not disappear at 18, and it is not sealed automatically on a birthday. Sealing closes the record so that, in the statute's words, the proceedings are deemed not to have occurred. Juvenile records are generally confidential to begin with. Adult records are generally public and usually harder to seal or expunge, depending on the state and the offense.

California has two main sealing pathways.

Sealing on completion (§ 786). Under Welf. & Inst. Code § 786, if a person satisfactorily completes informal supervision, probation under § 725, or a term of probation for any offense, the court shall dismiss the petition and seal the records. Satisfactory completion means two things: no new wardship finding or conviction for a felony or a misdemeanor involving moral turpitude during supervision, and no failure to substantially comply with reasonable orders within the person's capacity. There is an exception in § 786(d). The court shall not seal under § 786 if the petition was sustained on a § 707(b) offense committed at age 14 or older, unless that finding was dismissed or was reduced to a misdemeanor or to a lesser offense not listed in § 707(b).

Sealing by petition (§ 781). Under § 781, a person may petition five or more years after juvenile jurisdiction ends, or at any time after turning 18. The court orders sealing only if it finds two things: since jurisdiction ended, the person has not been convicted of a felony or of any misdemeanor involving moral turpitude, and rehabilitation has been attained to the court's satisfaction. For a § 707(b) offense committed at 14 or older that resulted in wardship, a petition may be filed or considered only in the circumstances § 781(a)(1)(D) lists.

School discipline, college admissions and employment consequences 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, which this page does not cover. School cases have their own page on school-related juvenile charges.

If You'd Like to Talk Through Your Child's Case

Knowing how the two systems differ is one thing. Knowing which court your child's case is in, and what comes next, is another. A consultation can cover the petition or the charge, whether your child is detained, which hearing is set and when, and whether transfer or sealing rules come into play. This page explains general rules. It does not cover how those rules apply to one family's facts.
