In California, offenses called "serious juvenile felonies" are the offenses on the specific list in Welfare and Institutions Code § 707(b), such as murder, robbery, forcible sex offenses, and assault with a firearm. That list figures in whether a case can be transferred to adult court, in who can be committed to a secure youth treatment facility, and in record sealing.
A parent or guardian may first hear about a charge like this in an unexpected phone call. Their son or daughter may be sitting in juvenile hall tonight, and the words they keep hearing, "707(b)," "transfer," "serious felony," sound like a verdict before anything has happened. They are trying to work out what the label means, whether their child can be sent to adult court, and whether this will follow the child for life. This page walks through each of those questions using California's own statute text.
What "Serious Juvenile Felony" Means Under California Law
Welf. & Inst. Code § 707(b) is the controlling statute. It does not create a general "severe crimes" category. It names particular offenses, one by one, and its rules apply only when a minor is accused of one of them.
A California juvenile case begins with a petition, the written document a prosecutor files in juvenile court that states what the minor is alleged to have done. Under Welf. & Inst. Code § 602, a minor who was between 12 and 17 years old, inclusive, when they allegedly broke a state or federal criminal law, or a local criminal ordinance other than an age-based curfew, comes within the juvenile court's jurisdiction. That same section allows a child under 12 to come within juvenile court jurisdiction only for a short list of offenses: murder and certain forcible sex offenses. Section 602 also begins with the words "Except as provided in Section 707." Those words mean the juvenile court's general jurisdiction over 12- to 17-year-olds gives way only as § 707 allows, which is why § 707 controls whether some cases leave juvenile court.
If the court finds the allegations true, it may make the minor a ward of the court. That means the juvenile court takes legal authority over the child's supervision and care, and it can make orders about where the child lives and what the child must do.
Adult criminal law uses its own categories, including those in Pen. Code § 1192.7. Those categories overlap with § 707(b) in places, but they are not the same list. For the juvenile court questions on this page, including whether a transfer hearing can happen, § 707(b) is the list that counts.
The Offenses Listed in Welfare and Institutions Code § 707(b)
The statute's own words are worth reading directly. Section 707(b) begins: "This subdivision is applicable to any case in which a minor is alleged to be a person described in Section 602 by reason of the violation of one of the following offenses." Then it lists 30 items:
- Murder.
- Arson, as provided in the Penal Code's arson statute.
- Robbery.
- Rape with force, violence, or threat of great bodily harm.
- Sodomy by force, violence, duress, menace, or threat of great bodily harm.
- A lewd or lascivious act, as provided in the Penal Code provision the statute cites.
- Oral copulation by force, violence, duress, menace, or threat of great bodily harm.
- A sexual penetration offense, as specified in the Penal Code provision the statute cites.
- Kidnapping for ransom.
- Kidnapping for purposes of robbery.
- Kidnapping with bodily harm.
- Attempted murder.
- Assault with a firearm or destructive device.
- Assault by any means of force likely to produce great bodily injury.
- Discharge of a firearm into an inhabited or occupied building.
- An offense described in a Penal Code provision the statute cites.
- An offense described in the Penal Code's firearm-use enhancement provisions the statute cites.
- A felony offense in which the minor personally used a weapon described in the Penal Code provisions the statute cites.
- A felony offense involving witness or victim intimidation, as described in the Penal Code provisions the statute cites.
- Manufacturing, compounding, or selling one-half ounce or more of a salt or solution of a controlled substance specified in the Health and Safety Code provision the statute cites.
- A violent felony, as defined in Pen. Code § 667.5(c), that would also be a felony violation of the Penal Code's criminal street gang statute.
- Escape by force or violence from a county juvenile hall, home, ranch, camp, or forestry camp, in violation of § 871(b), if great bodily injury is intentionally inflicted on a facility employee during the escape.
- Torture, as described in the Penal Code.
- Aggravated mayhem, as described in the Penal Code.
- Carjacking, as described in the Penal Code, while armed with a dangerous or deadly weapon.
- Kidnapping for purposes of sexual assault, as punishable in subdivision (b) of Pen. Code § 209.
- Kidnapping as punishable in Pen. Code § 209.5.
- The offense described in subdivision (c) of Pen. Code § 26100.
- The offense described in Pen. Code § 18745.
- Voluntary manslaughter, as described in subdivision (a) of Pen. Code § 192.
Item 21 borrows a definition from adult law. Pen. Code § 667.5(c) defines "violent felony" with its own list, including murder or voluntary manslaughter, mayhem, any robbery, kidnapping, carjacking, attempted murder, and certain sex offenses. Under § 707(b), one of those violent felonies counts only when it would also be a felony violation of the gang statute.
What matters is the conduct the petition alleges, measured against these items. A word used in a police report does not decide the question. Two offenses with similar names, such as simple assault and juvenile aggravated assault, can land on opposite sides of the list.
How the Juvenile Court Handles a § 707(b) Case: From Detention to Disposition
The court process can start before any hearing, with police questioning. Under Welf. & Inst. Code § 625.6, 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," and that consultation "may not be waived." The section has limits. It does not govern whether statements are admissible when an officer reasonably believed the information was needed to protect life or property from an imminent threat and asked only questions reasonably needed to get it. It also does not require a probation officer to follow it during certain normal duties.
A § 707(b) charge does not automatically mean a child stays locked up. Under Welf. & Inst. Code § 628, when police bring a minor to the probation officer, that officer must investigate immediately and release the child to a parent, guardian, or responsible relative. The exception applies only if the evidence shows that staying home is contrary to the child's welfare and at least one of these conditions exists: detention is urgently necessary 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.
If the child is held, the next step is the detention hearing, the court appearance where a judge decides whether the child stays in custody or goes home while the case continues. Under § 635, the court must order release unless those same kinds of grounds appear, or the minor escaped from a juvenile court commitment. The court may weigh "the circumstances and gravity of the alleged offense," but only in conjunction with other factors. Under § 636, a detention order may last no more than 15 judicial days, and the court must enter its findings in the record. The court may also order home supervision, with or without electronic monitoring, regardless of which county the child lives in.
Later comes the jurisdiction hearing, also called the adjudication hearing. This is where the court decides whether the minor committed the offense alleged in the petition. A finding that the allegations are true is an adjudication. If there is an adjudication, the court holds a disposition hearing, where it decides what happens next for the child. Options can include probation, which is court-ordered supervision in the community with conditions the child must follow; placement outside the home; or, for qualifying cases, commitment to a secure youth treatment facility. Some cases instead go to diversion, a program offered in place of filing a petition. Families who want the full sequence can see the California juvenile court process.
Transfer Hearings: When a § 707(b) Case Can Move to Adult Court
A transfer hearing is a court proceeding that decides whether a minor's case stays in juvenile court or moves to adult criminal court. Under § 707(a), a motion to transfer may be made for an offense alleged to have been committed when the minor was 16 or older (an offense listed in § 707(b) or any other felony), or for a § 707(b) offense committed at 14 or 15 by a person not apprehended before the end of juvenile court jurisdiction.
When a parent first hears that a case "might go adult," it can sound as though the decision has already been made. It has not. A transfer hearing is held in juvenile court, and it ends in one of two ways. The court can keep the case, and the case then continues through adjudication and disposition as described above. Or the court can order transfer, and the case then proceeds in adult criminal court.
The court may order a 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 it considers the probation officer's report, any other relevant evidence the petitioner or the minor submits, and the criteria in § 707(a)(3)(A) to (E). The site's guide to juvenile transfer hearings explains the hearing itself in more depth.
A transfer changes the stakes considerably. Once a case is in adult court, the result is governed by adult criminal law, which this page does not cover. That can include a criminal conviction and an adult record. The juvenile sealing rules described below are written for juvenile court records, not adult ones.
Consequences That Can Follow a § 707(b) Adjudication in Juvenile Court
Commitment to a secure youth treatment facility depends in part on the § 707(b) list. Under California Rules of Court, rule 5.804, a youth may be committed to a secure youth treatment facility if three conditions are all met. First, the youth committed an offense listed in section 707(b) when the youth was 14 years of age or older. Second, that offense is the most recent one for which the youth has been adjudicated. Third, the court finds on the record that a less restrictive alternative disposition is unsuitable, after considering all relevant evidence, including recommendations from counsel and the probation department.
The rule then requires a set of steps. The court must set a baseline term and a maximum term of confinement, and it must apply credit for time already served before commitment. The court must order probation to prepare an individualized rehabilitation plan and must approve a plan within 30 court days of the commitment order. It must also hold a progress review within six months to decide whether the baseline term should change. California's former Division of Juvenile Justice is no longer an option.
A case can also carry collateral consequences, which are legal effects beyond the court's disposition, such as registration requirements or limits on certain rights. Firearms are one example the statute text itself reflects: § 786 refers to sustained petitions that make a person ineligible to own or possess a firearm until age 30 under the Penal Code. Whether that applies depends on the offense and the facts.
Other consequences fall outside this page. Sex-offense registration, school discipline, and employment consequences depend on the specific offense, the facts, and rules this page does not cover. Immigration consequences are governed by immigration law this page does not cover. Record sealing is affected as well, as the next section explains.
Record Sealing After a § 707(b) Case
Sealing is a court order that closes off a juvenile record. Once a record is sealed, the statutes treat the proceedings as deemed not to have occurred, subject to the limited access rules described below. A juvenile record is not sealed automatically when a child turns 18, and sealing does not destroy the record on the day it is ordered.
For a parent looking twenty years ahead, three statutes describe three different routes to sealing.
Petition to the court (§ 781). Under Welf. & Inst. Code § 781, the person or the county probation officer may petition the court for sealing. The timing is five years or more after juvenile court jurisdiction ends, or five years after contact with probation or police if no petition was filed, or at any time after the person turns 18. The court notifies the district attorney and probation, who may testify. The court orders sealing if it finds that the person has not since been convicted of a felony or a misdemeanor involving moral turpitude, and that rehabilitation "has been attained to the satisfaction of the court." After sealing, "the proceedings in the case shall be deemed never to have occurred." For an offense listed in § 707(b) that was committed after the person turned 14 and resulted in wardship, § 781(a)(1)(D) allows a petition only in two circumstances: the person was committed to the Department of Corrections and Rehabilitation, Division of Juvenile Facilities, has turned 21 and has completed probation supervision after release; or the person was not so committed, has turned 18 and has completed any period of probation supervision related to that offense. Those limits do not apply if the offense was dismissed or reduced to a misdemeanor (§ 781(a)(1)(E)). If the person is required to register under Pen. Code § 290.008 for such an offense, the record shall not be sealed (§ 781(a)(1)(F)). A sealed § 707(b) record can still be accessed in the later proceedings the statute lists, including a later transfer motion (§ 781(a)(1)(D)(ii)).
Dismissal after completing probation (§ 786). Under § 786, when a ward satisfactorily completes informal supervision, probation under § 725, or a term of probation for any offense, the court must dismiss the petition and seal the records held by the court, law enforcement, probation, and the Department of Justice. It must also set a date for those records to be destroyed. For a record with a sustained petition that triggers the firearm ban until age 30, the destruction date is the person's 33rd birthday. Satisfactory completion generally means no new findings of wardship or felony or moral-turpitude misdemeanor conviction during supervision, along with other conditions. Under § 786(d), the court shall not seal a record or dismiss a petition under this section if the petition was sustained based on an offense listed in § 707(b) that was committed when the person was 14 years of age or older, unless the finding on that offense was dismissed or was reduced to a misdemeanor or to a lesser offense that is not listed in § 707(b).
Diversion (§ 786.5). When a youth completes diversion or supervision offered by probation or the prosecutor in place of a petition, the probation department must seal its records. Police and the Department of Justice must then seal theirs within 60 days of notice.
Sealed does not mean gone in every respect. Under § 787, agencies may access sealed records for required data reporting, and a court may allow researchers access. In both cases, personally identifying information may not be released.
Talking Through a § 707(b) Case
A § 707(b) allegation can bear on each stage described above: detention, a possible transfer hearing, disposition, and sealing. This page explains California's statute text and does not cover the specific facts of any one family's case.
