Yes, they can. A judge can dismiss a petition when the evidence falls short, a case can be closed through diversion or informal supervision, and in California a court must dismiss a petition once a child satisfactorily completes informal supervision or probation, except as Welf. & Inst. Code § 786(d) provides for certain offenses listed in § 707(b). None of these outcomes is automatic; each depends on the facts and the law.
This question comes from parents and guardians whose teenager has been arrested, cited or charged and who want to know whether this will follow their child into high school, college and adult life. This page explains how a juvenile case can end, what each ending means for the record, and where those endings fall in the court process, using California's rules as the worked example.
How Juvenile Court Cases Can End Without an Adjudication
Juvenile court has its own words, and they matter. A case starts with a petition, the document asking the court to take authority over the child, not a criminal complaint. The court holds an adjudication (California calls it a jurisdiction hearing), where a judge decides whether the allegations are proven. If they are, the petition is sustained; if not, it is dismissed. A sustained petition is not a conviction. The disposition is the court's later decision about what happens next, such as probation. Diversion is a program a child completes instead of going through formal court proceedings.
A case can end at three broad points. Before a petition is filed, probation or the prosecutor can send a child to a diversion or supervision program, or decide not to file at all. At adjudication, the petition can be dismissed or found not proven. After disposition, completing probation can lead to dismissal and sealing.
These rules change from state to state, including the ages juvenile court covers, who qualifies for diversion and how sealing works. The California rules below are California's, not a national standard.
What Diversion Means and When It Applies
Under Welf. & Inst. Code § 654, a probation officer who concludes that a minor is within the jurisdiction of the juvenile court may, with the consent of the minor and the minor's parent or guardian, refer the minor to services provided by a health agency, community-based organization, local educational agency, an appropriate non-law-enforcement agency or the probation department, in lieu of filing a petition. A program of supervision run by the probation department may not exceed six months. Under § 654.3, a minor is not eligible for the program of supervision in § 654 or § 654.2 in the case of a petition alleging an offense listed in § 707(b), except in unusual cases where the court makes an interests-of-justice determination and specifies its reason on the record; § 654.3(a) lists other cases of ineligibility, with a similar exception.
Diversion and informal supervision work at two points. Before a petition is filed, § 654 and § 786.5 describe referral of the minor to a program in place of a petition. After a petition has been filed by the prosecuting attorney, § 654.2 lets the court, without adjudging the minor a ward and with the consent of the minor and the minor's parents or guardian, continue any hearing on the petition for six months and order the minor to participate in a program of supervision; if the minor successfully completes the program, the court shall order the petition dismissed.
California law recognizes both routes. Under Welf. & Inst. Code § 786.5, the probation department "shall seal the citation, arrest, and other records in its custody" when a child satisfactorily completes a diversion or supervision program to which probation or the prosecutor referred the child "in lieu of the filing of a petition," including informal supervision. Under Welf. & Inst. Code § 786(a), when a person alleged or found to be a ward satisfactorily completes an informal program of supervision under § 654.2, probation under § 725 or a term of probation for any offense, "the court shall order the petition dismissed" and shall order the records sealed.
Satisfactory completion has a meaning. Section 786 treats it as met when the child has no new wardship finding or conviction for a felony or a misdemeanor involving moral turpitude during supervision and has not failed to substantially comply with reasonable orders within the child's capacity. Section 786(d) makes an exception: the court shall not seal a record or dismiss a petition under § 786 if the petition was sustained based on an offense listed in § 707(b) that was committed when the individual 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).
Grounds for Dismissing a Juvenile Petition
Under Welf. & Inst. Code § 701, proof beyond a reasonable doubt, supported by evidence legally admissible in the trial of criminal cases, must be adduced to support a finding that the minor is a person described by § 602. Under § 702, if the court finds after hearing the evidence that the minor is not such a person, it shall order that the petition be dismissed and the minor discharged from any detention or restriction ordered. A weapons case, a drug case and a theft case each have different elements, so the evidence needed differs too; this site's pages on juvenile drug charges and juvenile weapons charges cover two of them.
How evidence was gathered can matter. Under Welf. & Inst. Code § 700.1, a motion to suppress evidence obtained as a result of an unlawful search or seizure is heard before jeopardy attaches, and if the court grants it over the objection of the people at that point, the court enters a judgment of dismissal as to all counts of the petition except those on which the prosecuting attorney elects to proceed under § 701. California has a specific rule about 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," and that this consultation "may not be waived." When deciding whether a youth's statements can be used, the court must consider the effect of any failure to comply. The section does not apply when an officer reasonably believed the information was needed to protect life or property from an imminent threat and limited the questions to that, and it does not require probation officers to comply in certain normal duties.
Under Welf. & Inst. Code § 782, a judge of the juvenile court in which a petition was filed may dismiss the petition, or set aside the findings and dismiss it, if the court finds that the interests of justice and the welfare of the person who is the subject of the petition require that dismissal, or finds that the person is not in need of treatment or rehabilitation. The court may exercise that discretion at any time after the petition is filed, whether or not the petition was sustained at trial, by admission or by plea agreement, and a dismissal under § 782 does not by itself seal the records.
Procedural problems are different. In California, if a detained child is not brought before a judge in time, Welf. & Inst. Code § 632 says the child "shall be released from custody." That is release, not dismissal of the petition.
Serious and Violent Offenses and Transfer Hearings
A charge like robbery, a serious assault or a homicide brings a different fear: that the case will leave juvenile court altogether. A transfer hearing is where a judge decides whether a minor's case stays in juvenile court or moves to adult criminal court. This site's page on juvenile transfer hearings covers it in more depth.
In California, Welf. & Inst. Code § 707 governs transfer. The prosecutor may make a motion to transfer when the child is alleged to have committed, at 16 or older, an offense listed in the statute or "any other felony criminal statute." For a child who was 14 or 15, a motion is possible only for a listed offense and only if the person was not apprehended before juvenile court jurisdiction ended. The motion must be made prior to the attachment of jeopardy.
Transfer is not automatic. The court orders probation to prepare a report on the child's behavior and social history, including any statement from the alleged victim, and considers other evidence either side offers. To transfer, the judge must find "by clear and convincing evidence that the minor is not amenable to rehabilitation while under the jurisdiction of the juvenile court," consider criteria the statute specifies, and recite the basis for the decision in an order entered upon the minutes, including the reasons supporting the finding that the minor is not amenable to rehabilitation.
The offenses listed in § 707(b) include murder and robbery, and this site's juvenile robbery page covers robbery. If the court orders a transfer, the case moves from juvenile court to a court of criminal jurisdiction.
What Happens to a Juvenile Record After the Case Ends
In California, turning 18 does not by itself seal a juvenile record. Sealing closes the records so that, in California, the proceedings are deemed not to have occurred, with the access exceptions the sealing statutes list. California has several routes.
Under Welf. & Inst. Code § 781, the person or the county probation officer may petition the court to seal records five years or more after juvenile court jurisdiction ended, or at any time after the person turns 18. The court notifies the district attorney and probation, holds a hearing, and orders sealing if it finds the person has not been convicted of a felony or a misdemeanor involving moral turpitude since then and "that rehabilitation has been attained to the satisfaction of the court." Once sealed, "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, a petition may be filed or considered only in the circumstances listed in § 781(a)(1)(D), which turn on the person's age and on completing probation supervision; that limit does not apply if the offense was dismissed or reduced to a misdemeanor. A record of such an offense for which the person is required to register under Penal Code § 290.008 shall not be sealed.
Under § 786, dismissal after satisfactory completion of probation or informal supervision generally comes with a sealing order covering records held by the court, law enforcement, probation and the Department of Justice, subject to the § 786(d) exception described above. The person may then answer inquiries from employers and schools as though the arrest and proceedings did not occur. Where a sustained petition bars firearm possession until age 30, the sealed records are destroyed at age 33. Under § 786.5, probation seals records after completed diversion and notifies the arresting agency and the Department of Justice, which must seal theirs within 60 days.
Whether an unsealed record shows up on a particular background check depends on the type of check and rules this page does not cover. School discipline, employment and financial aid consequences can also follow a juvenile case and depend on the facts. Immigration consequences are governed by immigration law this page does not cover.
What the Process Generally Looks Like: From Arrest to Resolution
A juvenile case can move in this order: police contact, arrest or citation, probation intake, a decision to file a petition or divert, a detention hearing if the child is held, the jurisdiction hearing, disposition, then probation or another outcome, and later, sealing eligibility.
California's detention rules are specific. Under Welf. & Inst. Code § 628, the probation officer must immediately release the child to a parent, guardian or responsible relative unless continuing in the home is contrary to the child's welfare and one or more of these applies: continued detention is a matter of immediate and urgent necessity for the child's protection or reasonably necessary for the protection of another person or property, the child is likely to flee, or the child has violated a juvenile court order. Under § 631, a child must be released within 48 hours, excluding nonjudicial days, unless a petition or criminal complaint has been filed in that period, except for a minor who willfully misrepresents being 18 or older; § 631(b) sets a different rule for certain warrantless nonviolent misdemeanor custody. Under § 632, a held child must be brought before a judge for a detention hearing, the hearing on whether custody continues, before the end of the next judicial day after the petition is filed, with a 48-hour limit for certain nonviolent misdemeanors.
At that hearing, § 635 requires release unless grounds like those above appear, and the court considers the circumstances and gravity of the alleged offense alongside other factors. Under § 636, the court may order a minor detained for a period not to exceed 15 judicial days if it appears at the hearing that grounds like those above exist and continuing in the home is contrary to the minor's welfare, and the court may instead order home supervision, with or without electronic monitoring.
If a petition is sustained, the child may become a ward of the court, meaning the court takes legal authority over the child's supervision, and may be placed on probation, supervision with conditions the court sets. How long a child can be held or committed depends on the offense, history and disposition, and juvenile court authority ends at an age that varies by state. California's Division of Juvenile Justice no longer operates. Assault cases follow this same path; see California juvenile assault charges.
