Juvenile delinquency is the legal term for conduct by a person under eighteen that would be a crime if an adult did it. Federal law also folds in “status offenses” — things like truancy, curfew violations, and underage drinking that are illegal only because of the person’s age.1Office of the Law Revision Counsel. 18 USC 5031 – Definitions These cases do not go through adult criminal court. They are handled in a separate juvenile system built around rehabilitation, with its own vocabulary, its own procedures, and its own limits on how severely a young person can be punished.
Who Counts as a Juvenile
Federal law draws the line at eighteen. Under 18 U.S.C. § 5031, a juvenile is someone who has not yet reached their eighteenth birthday, and the offense must have been committed before that birthday to count as juvenile delinquency. The same statute lets the court keep authority over a person up to age twenty-one to finish proceedings or carry out a disposition that began while they were still a minor.1Office of the Law Revision Counsel. 18 USC 5031 – Definitions
Nearly every state now sets the upper age of juvenile court jurisdiction at seventeen, meaning anyone who committed the offense before turning eighteen goes to juvenile court. Since 2007, eleven states have raised their cutoff to eighteen, and Vermont has extended original jurisdiction up to nineteen. A handful of states still send seventeen-year-olds to adult court for certain offenses.2Office of Juvenile Justice and Delinquency Prevention. Age Boundaries of the Juvenile Justice System
Most states have no statutory minimum age for juvenile prosecution. Among the states that do set a floor, it ranges from six to twelve.2Office of Juvenile Justice and Delinquency Prevention. Age Boundaries of the Juvenile Justice System In practice, very young children are almost always sent to social services rather than brought before a judge. Many states also allow juvenile courts to keep supervising a young person past the usual upper age boundary to finish a treatment plan, sometimes into the early twenties.3Office of Juvenile Justice and Delinquency Prevention.

Two Kinds of Conduct: Delinquent Acts and Status Offenses
The definition covers two different categories of behavior, and the distinction shapes how the case is handled.
A delinquent act is conduct that would be a crime regardless of the person’s age: shoplifting, vandalism, car theft, assault, robbery, drug offenses, and so on. When a minor is accused of one of these, the juvenile system uses different language than adult court. The young person is not “convicted” but “adjudicated delinquent,” and the sentencing stage is called a “disposition” rather than a sentence. The conduct is the same conduct an adult could be charged with; the forum and the framework are different.
A status offense, by contrast, is behavior that is only illegal because the person is a minor. An adult who skips work, stays out past midnight, or buys a pack of cigarettes faces no legal consequence. A minor doing something equivalent can be brought before a juvenile court. The most common examples are truancy, running away from home, curfew violations,4Office of Juvenile Justice and Delinquency Prevention. Youth Curfews and possession of alcohol or tobacco. Federal law prohibits tobacco sales to anyone under twenty-one,5Food and Drug Administration. Tobacco 21 and every state restricts alcohol to those twenty-one and over. Status-offense cases typically result in counseling, education, community service, or referral to social services rather than confinement.
Why the System Treats Juveniles Differently
The juvenile system rests on a doctrine called parens patriae, Latin for “parent of the country.” The idea is that the state has the authority and the obligation to step in when a child’s welfare or the public’s safety requires it. The first juvenile court, established in Cook County, Illinois, in 1899, was built on this premise: rather than treating children as small adults deserving punishment, the system would act as a substitute parent focused on correction and care.
In practice, that philosophy gives juvenile judges unusually broad tools. A judge can order psychological evaluations, substance-abuse treatment, educational tutoring, family counseling, community service, or placement outside the home. The goal is not to match the punishment to the crime, as in adult court, but to figure out what intervention gives this young person the best chance of becoming a productive adult.6Youth.gov. Points of Intervention That is also why the system still treats the consequences seriously — residential placement, electronic monitoring, intensive probation — even as it keeps the label and the record separate from the adult criminal system.
How a Juvenile Case Moves Through Court
A juvenile case looks different from an adult criminal case at almost every stage.
Intake and Diversion
When a young person is referred to the juvenile system, usually by law enforcement, the first step is intake. A probation officer or prosecutor reviews the case and decides whether to dismiss it, handle it informally, or file a formal petition asking the court to adjudicate the youth delinquent. Less than half of all referred cases proceed to formal court action.7Office of Juvenile Justice and Delinquency Prevention. Case Flow Diagram An informal resolution typically requires the youth to agree to conditions like community service, restitution, counseling, or a curfew.
Diversion programs take this a step further, redirecting young people away from court entirely and into community-based services like family counseling, substance-abuse education, mentoring, or job training.8Youth.gov. Diversion Programs A young person who completes diversion successfully usually avoids any formal record. Diversion is most commonly offered for first-time, nonviolent offenses.
Detention, Adjudication, and Disposition
If a youth is held in custody after arrest, a detention hearing generally has to happen within about twenty-four hours, where a judge decides whether continued detention is warranted. Many youths are released to their parents while the case moves forward.7Office of Juvenile Justice and Delinquency Prevention. Case Flow Diagram
The adjudication hearing is the juvenile equivalent of a trial. Witnesses testify, evidence is presented, and the prosecution has to prove the allegations beyond a reasonable doubt. In most states there is no jury. A judge alone decides whether the youth committed the alleged act.7Office of Juvenile Justice and Delinquency Prevention. Case Flow Diagram
If the court finds the youth responsible, the case moves to the disposition hearing. The judge picks from a menu that includes probation, community service, restitution, counseling, placement in a group home or residential treatment facility, or commitment to a secure juvenile facility for the most serious offenses. The judge considers the offense, the youth’s prior history, the family situation, school record, mental health, and likely response to treatment.
The Rights a Juvenile Has in Court
For decades, juvenile courts operated with almost no formal procedural protections, on the theory that acting in the child’s best interest was enough. The Supreme Court changed that starting in the 1960s.
Kent v. United States (1966) held that a juvenile facing transfer to adult court is entitled to a hearing, access to counsel, and a written statement of the court’s reasons.9Justia. Kent v United States, 383 US 541 (1966) The next year, In re Gault (1967) established the core due process rights that still govern juvenile adjudications:
- Written notice of the charges, given early enough to prepare a defense.
- The right to an attorney, including appointed counsel if the family cannot afford one.
- The right against self-incrimination.
- The right to confront and cross-examine witnesses.10Justia. In re Gault, 387 US 1 (1967)
In re Winship (1970) added the “beyond a reasonable doubt” standard of proof, the same one used in adult criminal trials.11Cornell Law Institute. In the Matter of Samuel Winship, Appellant One major right the Supreme Court has not extended to juveniles is the right to a jury trial. A small number of states grant jury trials by statute, but most do not.
When a Juvenile Is Tried as an Adult
The juvenile system assumes young people can be rehabilitated. When an offense is severe enough, or a youth’s history makes rehabilitation look unlikely, the case can be moved to adult criminal court — a decision with major consequences, because an adult conviction carries adult penalties and a permanent record.
States use three main mechanisms. Judicial waiver is the most common: the juvenile court judge holds a hearing and decides whether to give up jurisdiction, weighing the seriousness of the offense, the youth’s prior record, and the prospects for rehabilitation. Statutory exclusion takes the decision out of the judge’s hands by sending certain offenses — most often murder and other serious violent felonies — directly to adult court when committed by juveniles above a specified age. Direct file, used in some states, gives prosecutors the discretion to charge a juvenile in adult court without a waiver hearing.12Office of Juvenile Justice and Delinquency Prevention. Juvenile Transfer to Criminal Court
Federal law allows transfer of juveniles fifteen or older accused of a violent felony or serious drug offense when the court finds it would be “in the interest of justice,” with the age threshold dropping to thirteen for certain violent crimes.13Office of the Law Revision Counsel. 18 USC 5032 – Delinquency Proceedings in District Courts Some states enforce “once waived, always waived” rules, so a juvenile who has been transferred once is automatically handled in adult court for any future offense.12Office of Juvenile Justice and Delinquency Prevention. Juvenile Transfer to Criminal Court
Limits on How Harshly a Juvenile Can Be Punished
The Supreme Court has drawn constitutional lines around the harshest penalties when applied to minors, grounded in the Eighth Amendment’s ban on cruel and unusual punishment.
Roper v. Simmons (2005) held that executing anyone for a crime committed before age eighteen is unconstitutional.14Justia. Roper v Simmons, 543 US 551 (2005) Graham v. Florida (2010) ruled that a juvenile cannot be sentenced to life without parole for a non-homicide offense, and that states have to provide “some meaningful opportunity to obtain release based on demonstrated maturity and rehabilitation.”15Justia. Graham v Florida, 560 US 48 (2010) Miller v. Alabama (2012) extended the logic to homicide cases, striking down mandatory life-without-parole sentences for juvenile offenders; a judge can still impose that sentence in rare cases, but only after an individualized hearing.16Justia. Miller v Alabama, 567 US 460 (2012) Montgomery v. Louisiana (2016) made Miller retroactive, so people already serving mandatory juvenile life-without-parole sentences became eligible for resentencing.17Justia. Montgomery v Louisiana, 577 US 190 (2016)
Together these cases establish that even a juvenile convicted of the most serious crimes must receive a sentence that accounts for their youth and capacity to change.
Whether the Record Follows You
One of the most important features of the juvenile system is that a case does not have to follow a person for life. Most states let juvenile records be sealed, so they do not appear on standard background checks. Some states allow expungement, which destroys the record entirely.
The process varies by state. A growing number of states seal or expunge juvenile records automatically when the person reaches a certain age or completes their sentence; others require a petition. California seals records on successful completion of probation. Connecticut erases youthful-offender records when the person turns twenty-one. Several states set the automatic trigger at the twenty-first birthday as well. Even where a petition is required, the process is generally less burdensome than adult expungement, with modest filing fees and shorter waiting periods.
Not every offense qualifies. The most serious offenses — particularly those involving violence or sexual conduct, and those that could have been transferred to adult court — are often excluded. Sealed records also carry some residual effects: law enforcement and certain government agencies can still access them, and some professional licensing boards can ask about sealed adjudications. For most everyday purposes, though, including employment and housing applications, a sealed record effectively does not exist. For young people who stay out of further trouble, the ability to clear a juvenile record is one of the system’s most meaningful protections.
