When a child is being held after an arrest, the juvenile detention hearing is the short court hearing where a judge decides whether the child goes home or stays in custody while the case continues. It happens soon after the arrest, on a deadline set by state law. It does not decide whether the child did what is alleged.

If your child is in juvenile hall tonight, you are probably waiting by the phone, unsure who decides anything, when you will see your child, or whether the next court date means the case is already being decided. This page walks through the order of events: the first hours in custody, the detention hearing itself, the right to a lawyer, and the stages that follow, using California's rules as the worked example.

Before You Start: What This Page Covers and What Varies by State

Juvenile law in the United States is mostly state law. The ages a juvenile court covers, how fast a hearing must follow an arrest, the grounds for holding a child, and the rules for sealing a record all differ from state to state. The federal Office of Juvenile Justice and Delinquency Prevention puts it plainly: each state's processing of law violators is unique, and practice varies even between communities in the same state. Where this page states a California rule, it says so.

A few terms come up throughout:

  • Petition: the formal document that starts a juvenile court case. It is not a criminal complaint.
  • Detention hearing: the first hearing, deciding whether a held child stays detained.
  • Jurisdiction hearing (also called an adjudication hearing): the hearing where the court decides whether the petition's allegations are true. A finding there is not a conviction.
  • Disposition: the court's order about what happens next if the allegations are found true. It is not a sentence.
  • Ward of the court: a child the juvenile court has taken under its authority and supervision.
  • Probation: court-ordered supervision in the community, with conditions.
  • Diversion: handling a case through a program instead of a formal petition or adjudication.
  • Transfer hearing: a hearing on whether a case moves to adult criminal court.
  • Sealing: a court order limiting access to juvenile records.

In California, under Welf. & Inst. Code § 602, the juvenile court generally covers minors who were 12 through 17 when they allegedly broke a law defining a crime (other than an age-based curfew ordinance), subject to the transfer rules of § 707. A child under 12 comes within the court's jurisdiction only for offenses the statute lists, which are murder and specified forcible sex offenses.

A detention hearing resolves two things: whether the child stays detained or is released, and what conditions come with either outcome.

Step 1 — Arrest and Initial Custody: What Happens in the First Hours

The first decision after an arrest is usually made by police, not a judge. The OJJDP case flow overview explains that at arrest, law enforcement generally decides whether to send the matter further into the system or divert it out, and that a youth taken to a detention facility is reviewed by probation officers or detention workers who decide whether to hold the youth pending a hearing.

In California, Welf. & Inst. Code § 628 tells the probation officer what to do when a minor is delivered to them: investigate immediately and release the minor to a parent, legal guardian or responsible relative. The exception applies only if continuing in the home is contrary to the minor's welfare and at least one of these conditions exists: detention is an immediate and urgent necessity to protect the minor, or reasonably necessary to protect another person or property; the minor is likely to flee; or the minor has violated a juvenile court order.

Welf. & Inst. Code § 631 sets an outer limit. A minor taken into custody generally must be released within 48 hours, excluding nonjudicial days, unless a petition to declare the minor a ward or a criminal complaint is filed within that time. That limit does not apply when the minor willfully misrepresents being 18 or older. For a warrantless arrest 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, when the minor is not currently on probation or parole, § 631(b) requires release within 48 hours, excluding nonjudicial days, unless a petition has been filed and a judge or referee has ordered the minor detained under § 635.

Questioning has its own California rule. Under Welf. & Inst. Code § 625.6, before a custodial interrogation and before any waiver of Miranda rights, a youth 17 or younger must consult with legal counsel in person, by phone or by video, and that consultation cannot be waived. The section does not apply to the admissibility of statements if the officer who questioned the youth reasonably believed the information sought was necessary to protect life or property from an imminent threat and the questions were limited to those reasonably necessary to obtain that information, and it does not require a probation officer to comply in the normal performance of the officer's duties under the sections it names. Nationally, the U.S. Supreme Court in In re Gault, 387 U.S. 1 (1967), held that the constitutional privilege against self-incrimination is applicable in the case of juveniles as it is with respect to adults.

Step 2 — The Detention Hearing: What the Court Decides and When It Must Happen

The detention hearing is the first time a judge looks at whether a held child should stay held. The OJJDP overview states that in all states a detention hearing must be held within a time set by statute, generally within 24 hours, and that the youth may be released or detention continued.

California's timing rule is Welf. & Inst. Code § 632. Unless the minor is sooner released, a detained minor must be brought before a juvenile court judge or referee as soon as possible, and in any event before the end of the next judicial day after the petition is filed. Section 632(b) sets a different limit for a minor taken into custody without a warrant on the belief that the minor committed a misdemeanor not involving violence, a threat of violence, or possession or use of weapons, when the minor is not currently on probation or parole: the hearing must be held 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. A minor not brought before the judge or referee within the period prescribed must be released.

At the hearing, Welf. & Inst. Code § 635 directs the court to examine the minor, the parent or guardian, or others with relevant knowledge, and to hear evidence the minor, parent or counsel wants to present. The court must order release unless the minor violated a juvenile court order, escaped from a juvenile court commitment, needs to be held as an immediate and urgent necessity for their own protection or as reasonably necessary to protect another person or property, or is likely to flee. The circumstances and gravity of the alleged offense may be weighed alongside other factors. The decision cannot rest solely on the minor's county of residence. Release is also required unless there is a prima facie showing that the minor falls within § 601 or § 602.

Under Welf. & Inst. Code § 636, if those grounds are shown and staying home is contrary to the minor's welfare, the court may order detention in juvenile hall or another suitable place for a period not to exceed 15 judicial days, and must enter the order together with its findings of fact in the court's records. If the home supervision criteria of § 628.1 apply, the court must place the minor on home supervision instead, also for up to 15 judicial days. Under § 628.1, home supervision means release to a parent, guardian or responsible relative on written conditions, which may include curfew and school attendance requirements, and a minor on home supervision is entitled to the same legal protections as a minor in secure detention, including a detention hearing. Under § 636(a), it may include electronic monitoring. Every minor must get equal consideration for home supervision wherever they live.

This hearing does not decide guilt or innocence. That question belongs to the jurisdiction hearing.

Step 3 — The Right to Counsel: What In re Gault Established and What It Means Today

In re Gault, 387 U.S. 1 (1967), is the U.S. Supreme Court decision holding that the Due Process Clause of the Fourteenth Amendment requires, in proceedings to determine delinquency which may result in commitment to an institution in which the juvenile's freedom is curtailed, that the child and the parents be notified of the child's right to be represented by counsel, and that counsel be appointed if they are unable to afford counsel. Gault also held that the privilege against self-incrimination applies to juveniles as it does to adults. In California, Welf. & Inst. Code § 633 requires that at the detention hearing the minor and a parent or guardian, if present, first be informed of the reasons the minor was taken into custody, the nature of the juvenile court proceedings, and the right to be represented at every stage of the proceedings by counsel. Welf. & Inst. Code § 634 requires the court to appoint counsel for a minor alleged to be a person described in § 601 or § 602 who appears at the hearing without counsel, unless the minor intelligently waives the right.

Step 4 — After the Detention Hearing: The Path to Adjudication, Disposition, and Beyond

The detention hearing decides where the child stays. The rest of the case follows a common series of decision points described in the OJJDP case flow overview. The full arc is set out in the site's juvenile court process guide.

Jurisdiction (adjudication) hearing. Witnesses are called and evidence is presented, and the court decides whether the petition's allegations are true. OJJDP notes that in nearly all such hearings a judge decides, though some states give a youth the right to a jury trial.

Disposition hearing. If the petition is sustained, probation staff prepare a report, and the prosecutor and the youth may offer recommendations before the judge orders a disposition. OJJDP describes probation that may include counseling, weekend confinement, community service or restitution, and residential placement in some cases. A child declared a ward of the court comes under the court's supervision. In California, the former Division of Juvenile Justice no longer operates.

Transfer. In California, Welf. & Inst. Code § 707 allows the prosecutor to move to transfer a minor to criminal court. The motion must come before jeopardy attaches. The adult court transfer guide covers this in more depth.

Diversion. OJJDP explains that intake may dismiss a case, handle it informally, or request formal court action. In an informal case, the youth may agree to conditions under a written agreement, and in most jurisdictions an informal disposition is offered only if the youth admits the act. Availability depends on the state, the county and the facts.

Sealing. In California, Welf. & Inst. Code § 786 requires the court to dismiss the petition and seal the related records when a ward satisfactorily completes informal supervision under § 654.2, probation under § 725, or a term of probation for any offense, except that § 786(d) bars dismissal and sealing under that section where the petition was sustained on an offense listed in § 707(b) committed at 14 or older, unless that finding was dismissed or reduced to a misdemeanor or to a lesser offense not listed in § 707(b). Once dismissed, the arrest and proceedings are deemed not to have occurred. Under § 786.5, the probation department seals records after satisfactory completion of diversion or supervision offered instead of a petition. Under § 781, a person may petition for sealing five years or more after jurisdiction ends, or at any time after turning 18. If the court finds that the person has not been convicted of a felony or of a misdemeanor involving moral turpitude since jurisdiction ended and that rehabilitation has been attained to the court's satisfaction, it orders the records sealed. For a § 707(b) offense committed at 14 or older that resulted in wardship, § 781 adds conditions: a petition may be filed only after the person has attained 18 and completed any probation supervision for that offense (21 if committed to the state juvenile facilities division the statute names), unless the finding was dismissed or reduced to a misdemeanor, and a record is not sealed if the person must register under Penal Code § 290.008. Under § 787, sealed records remain accessible in limited ways, including for required data reporting and approved research.

A juvenile case can also affect school, employment and other areas, depending on the facts and on rules this page does not cover. Immigration consequences are governed by immigration law this page does not cover.

Step 5 — Counsel at Each Stage: What the Statutes Say

Several California statutes speak to counsel at particular stages.

  • Initial custody and questioning: § 625.6 requires a youth 17 or younger to consult with legal counsel before a custodial interrogation and before waiving any Miranda rights.
  • Detention hearing: § 633 requires that the minor and a parent or guardian, if present, first be informed of the right to be represented by counsel at every stage of the proceedings, and § 635(a) has the court hear relevant evidence that the minor, the parent or guardian, or counsel desires to present.
  • Jurisdiction hearing: § 701 provides that if the minor is not represented by counsel at the hearing, objections that could have been made to the evidence are deemed to have been made.
  • Transfer hearing: under § 707, the central question is whether the minor is not amenable to rehabilitation while under the jurisdiction of the juvenile court, and the court considers the probation report and any other relevant evidence that the petitioner or the minor may wish to submit.

Typical Timeline: From Arrest to Disposition

How long a case takes depends on the state, the county's court calendar, and how complex the case is. The usual sequence runs like this:

  1. Arrest.
  2. A custody decision by police and probation, within hours.
  3. A detention hearing, within days. In California, this happens by the end of the next judicial day after the petition is filed, with the different limit in § 632(b) for the cases it lists.
  4. Further hearings, including a jurisdiction hearing. In California, § 657 requires the petition to be set for hearing within 30 days of its filing, or within 15 judicial days from the date of the order directing detention if the minor is detained in custody, with a separate rule where a warrant of arrest has been issued and the minor was not before the court when the petition was filed.
  5. A disposition hearing.
  6. Probation or another disposition lasting months or longer, with the length set by the court.

In California, a detention order under § 636 is for a period not to exceed 15 judicial days. A contested case usually takes longer than one resolved through an admission or diversion. A transfer motion adds a separate hearing before any jurisdiction hearing. Continuances, witness availability, the complexity of the alleged offense, and court-ordered evaluations can all extend the timeline. OJJDP also notes that detention can sometimes continue past disposition until a placement bed is available.

When the Process Gets Complicated: Transfer to Adult Court, Serious Offenses, and Repeat Petitions

A transfer motion

In California, under § 707, the prosecutor may seek transfer when a minor was 16 or older at the time of any offense listed in § 707(b) or any other felony. A minor who was 14 or 15 at the time of a listed offense may also face transfer, but only if they were not apprehended before juvenile court jurisdiction ended. The court orders a probation report on the minor's behavioral patterns and social history, including any victim statement. It may transfer only on clear and convincing evidence that the minor is not amenable to rehabilitation in the juvenile court, considering the criteria the statute specifies.

Different rules elsewhere

OJJDP describes states that require certain serious cases to be filed in criminal court, and others that let prosecutors choose the court for a defined list of cases. Which pattern applies depends on the state. A transferred case is handled in criminal court, where an outcome can be a conviction and adult sentencing rules apply.

Serious or repeat allegations

Under California's §§ 635 and 636, the court may weigh the gravity of the alleged offense and whether the minor violated a court order. OJJDP notes that prosecutors seeking transfer may point to prior adjudications. Information on specific charges, such as California juvenile assault charges, appears in this site's offense guides, and broader context is in the overview of juvenile crimes.

Under § 707, the court considers the probation report and any other relevant evidence that the petitioner or the minor may wish to submit. The outcome depends on that evidence and the statutory criteria.

Requesting a Consultation About a Detention Hearing
