When a child is accused of a crime in Santa Clara County, the case is handled in juvenile court rather than adult court, unless it is transferred, under California's Welfare and Institutions Code. The county court's Juvenile Division page says the case goes to the Juvenile Justice Courthouse on Guadalupe Parkway in San Jose.

This page explains how a juvenile case moves through this county's court and probation system, using what California law and the county's official pages say.

How Santa Clara County Juvenile Court Works

The Superior Court's Juvenile Division page says that juvenile courts handle cases of children under 18 who violate any law. When a child is accused of a crime, the case is heard at the Juvenile Justice Courthouse, 840 Guadalupe Parkway in San Jose, part of the Superior Court of California, County of Santa Clara.

Juvenile court is not adult criminal court, and it uses different words. The case starts with a petition, a written document asking the court to declare the child a ward of the court. A detention hearing decides whether the child stays in custody while the case is pending. At the jurisdiction hearing, also called the adjudication, the court decides whether the allegations in the petition are true. At the disposition hearing, the court decides what happens next. One possible result is probation.

The Santa Clara County Probation Department runs the county's juvenile institutions. Probation officers make detention decisions, and under California law they prepare reports for the court, including the report a judge reviews before deciding a transfer motion. The federal Office of Juvenile Justice and Delinquency Prevention notes that case processing often varies from community to community. That variation is why the county-level details on this page matter.

Arrest and Detention in Santa Clara County: What Happens First

Under Welf. & Inst. Code § 625.6, a youth 17 years of age or younger must consult with legal counsel before a custodial interrogation and before waiving any Miranda rights. The consultation can happen in person, by telephone or by video conference, and it cannot be waived. The statute has exceptions. It does not apply to the admissibility of statements when an officer reasonably believed the information was needed to protect life or property from an imminent threat and limited the questions to what was reasonably necessary. It also does not require a probation officer to comply when performing certain normal duties.

A minor brought to custody may be held at Juvenile Hall at 840 Guadalupe Parkway, San Jose. The Probation Department's juvenile institutions page describes Juvenile Hall as temporary residential housing for youth awaiting adjudication or disposition. It says that if a child has been taken to Juvenile Hall, a staff person will contact the parent.

Under Welf. & Inst. Code § 631, a minor taken into custody generally must be released within 48 hours, excluding nonjudicial days, unless a petition or a criminal complaint is filed within that time. This rule does not apply when a minor willfully misrepresents themselves as 18 or older. Under § 632, a detained minor must be brought before a juvenile court judge or referee before the end of the next judicial day after the petition is filed. If the child is not brought to court in time, the child must be released. A 48-hour rule applies instead to certain warrantless arrests for nonviolent misdemeanors when the minor is not on probation or parole.

At the detention hearing, § 635 requires the court to release the minor unless one of these grounds appears:

the minor violated a juvenile court order;
the minor escaped from a juvenile court commitment;
detention is a matter of immediate and urgent necessity for the minor's protection;
detention is reasonably necessary to protect another person or property; or
the minor is likely to flee.

Under §§ 635(b)(2) and 636, a minor must be given equal consideration for release on home supervision regardless of whether the minor lives in the county where the offense occurred.

Hearings, Diversion and Transfer

At the detention hearing, § 635 allows the minor, the parent or counsel to present relevant evidence. Home supervision under § 636 may include electronic monitoring. If the court orders detention, § 636 limits the order to no more than 15 judicial days, and the court must enter its findings of fact.

Diversion means handling a case without a sustained petition. Under Welf. & Inst. Code § 654, a probation officer may, with the consent of the minor and the parent or guardian, refer the minor to services instead of filing a petition. When the probation department provides the services, the supervision program lasts no more than six months. A petition can still be requested during that period or within 90 days after it, or if the minor has not participated within 60 days. Whether diversion is offered depends on the probation officer's judgment and the facts of the case.

A transfer hearing decides whether a case moves to a court of criminal jurisdiction. Under § 707(a), the prosecution may move for transfer only in two situations:

the offense is alleged to have been committed when the minor was 16 or older, and it is a § 707(b) offense 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 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. The court considers the probation officer's report and any other relevant evidence that the petitioner or the minor may wish to submit. More on this stage appears in the overview of juvenile felony defense.

Types of Cases Handled in Santa Clara County Juvenile Court

Welf. & Inst. Code § 602 sets the basic reach of juvenile court. Except as § 707 provides, a minor between 12 and 17, inclusive, who violates a state or federal law, or a local ordinance defining a crime, is within the juvenile court's jurisdiction. Curfew ordinances based solely on age are excluded. A child under 12 comes within juvenile court jurisdiction only for the offenses § 602(b) lists:

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

Petitions can involve allegations such as theft, assault, drug offenses, weapons, or conduct connected to school. The type of offense matters. Section 707(b) contains a list of serious offenses, and a § 707(b) allegation affects both whether transfer is possible and whether a record can later be sealed. Sex-offense petitions raise additional issues, discussed on the page about juvenile sex crimes.

School consequences depend on the facts and on rules this page does not cover. Discipline with no police involvement or criminal charge is outside this site's scope.

Record Sealing in Santa Clara County: What the Law Allows

A juvenile record does not disappear or seal automatically at 18. California law provides two main routes to sealing.

Sealing on satisfactory completion (§ 786). When a person satisfactorily completes any of the following, the court shall order the petition dismissed and the records sealed:

an informal program of supervision under § 654.2;
probation under § 725; or
a term of probation for any offense.

After dismissal, the arrest and proceedings are deemed not to have occurred. There is an exception. Under § 786(d), the court shall not seal a record or dismiss a petition under § 786 if the petition was sustained on a § 707(b) offense committed at 14 or older. That bar lifts only if the finding on that offense was dismissed or was reduced to a misdemeanor or to a lesser offense not listed in § 707(b).

Sealing by petition (§ 781). A person may petition the court five years or more after juvenile court jurisdiction ends, or at any time after turning 18. The court orders sealing only if it finds two things: 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 the person attained 14 years of age that resulted in wardship, a petition may be filed or considered only if the person was committed to the Department of Corrections and Rehabilitation, Division of Juvenile Facilities, has reached 21 and has completed probation supervision after release from the division, or was not so committed, has reached 18 and has completed any probation supervision related to the offense (§ 781(a)(1)(D)). That limit does not apply where the § 707(b) offense was dismissed or reduced to a misdemeanor by the court (§ 781(a)(1)(E)), and a record of such an offense for which the person is required to register under section 290.008 of the Penal Code is not sealed (§ 781(a)(1)(F)).

Employment, college admissions and financial aid consequences can follow a juvenile case. 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.

Frequently asked questions

What court handles juvenile cases in Santa Clara County?

When a child is accused of a crime, the case goes to the Superior Court of California, County of Santa Clara, at the Juvenile Justice Courthouse, 840 Guadalupe Parkway, San Jose. Dependency cases about a parent's care of a child are heard at a different courthouse.

How soon does a detention hearing happen after a minor is arrested in Santa Clara County?

Under § 632, a detained minor must be brought before a juvenile court judge or referee before the end of the next judicial day after the petition is filed. For certain nonviolent misdemeanors, when the minor is not on probation or parole, the limit is 48 hours, excluding nonjudicial days. If the deadline is missed, the minor must be released.

Does a juvenile record automatically seal when a child turns 18 in California?

No. Sealing happens under § 786 after satisfactory completion of supervision or probation, except for § 707(b) offenses committed at 14 or older unless that finding was dismissed or reduced. Sealing can also happen by petition under § 781, which requires no felony or moral-turpitude misdemeanor conviction since jurisdiction ended, plus rehabilitation the court accepts. For a § 707(b) offense committed after age 14 that resulted in wardship, a petition is allowed only in the circumstances § 781(a)(1)(D) sets, which include an age of 18 or 21 and completed probation supervision.

Can a juvenile case be transferred to adult court in Santa Clara County?

Yes, but only on a § 707(a) motion. The motion is allowed for a § 707(b) offense or other felony alleged at 16 or older, or for a § 707(b) offense alleged at 14 or 15 by a person not apprehended before jurisdiction ended. Transfer also requires clear and convincing evidence that the minor is not amenable to rehabilitation in juvenile court.

What rights does a minor have when questioned by police in California?

Under § 625.6, a youth 17 or younger must consult with legal counsel in person, by phone or by video before a custodial interrogation and before waiving Miranda rights. The consultation cannot be waived. The statute has limited exceptions for imminent threats to life or property and for certain probation officer duties.

What is diversion in Santa Clara County juvenile court?

Diversion resolves a case without a sustained petition. Under § 654, a probation officer may, with the consent of the minor and the parent or guardian, refer the minor to services instead of filing a petition. Whether that happens depends on the probation officer's judgment and the facts of the case.

What is the difference between a juvenile adjudication and a criminal conviction?

A juvenile adjudication is a finding at the jurisdiction hearing that the allegations in the petition are true. It is not a criminal conviction. What follows is a disposition, not a sentence, and it may include declaring the child a ward of the court.
