How delinquency cases begin under A.R.S. § 8-301, what rights your child has, and how adjudications get set aside under A.R.S. § 8-348

A phone call from a school resource officer or a Maricopa County sheriff's deputy telling you that your child has been arrested is one of the most frightening moments a parent can face. The good news: Arizona's juvenile justice system is built around rehabilitation rather than punishment, and children in delinquency proceedings have robust legal rights — many of them established by In re Gault, a landmark U.S. Supreme Court case that began right here in Arizona. The bad news: the system moves fast, the stakes are real, and for certain serious offenses Arizona law requires prosecutors to charge teenagers as adults.
This guide explains how juvenile delinquency cases work in Maricopa County Juvenile Court, what happens at each stage from referral through disposition, when a case can end up in adult court, and how a young person can clear their record later under A.R.S. § 8-348.
Juvenile delinquency proceedings are commenced under A.R.S. § 8-301, which governs how a case formally enters the juvenile court system. In practice, most cases start with a referral: a police officer who arrests or cites a minor forwards the case to the juvenile court and the county attorney. In Maricopa County, that means the Maricopa County Attorney's Office Juvenile Division, which handles charging decisions for youth arrested anywhere in the Phoenix metro — from Glendale to Tempe to Gilbert.
Arizona juvenile court has jurisdiction over children under 18 who are alleged to have committed a delinquent act — conduct that would be a criminal offense if committed by an adult — or who are alleged to be incorrigible (status offenses like chronic truancy, running away, or curfew violations that only a minor can commit). Once a referral arrives, the county attorney has several options:
The single most important early question in any Arizona juvenile case is whether it stays in juvenile court. Under A.R.S. § 13-501, the county attorney must charge a juvenile who was 15, 16, or 17 at the time of the offense as an adult for the most serious crimes, including first- and second-degree murder, forcible sexual assault, armed robbery, and certain other violent offenses. The statute also gives prosecutors discretion to charge 14- to 17-year-olds as adults for other felonies, including when the juvenile qualifies as a chronic felony offender.
Separately, the state can ask the juvenile court itself to transfer a case to adult criminal court after a transfer hearing, where the judge weighs the seriousness of the offense, the juvenile's record, and the prospects for rehabilitation within the juvenile system.
Thanks to In re Gault (1967) — a case that arose from Gila County, Arizona — juveniles in delinquency proceedings nationwide are guaranteed core due-process rights. In Arizona these include:
There is one major difference from adult court: no jury. Delinquency cases are decided by a juvenile court judge at a bench trial called an adjudication hearing.
Parents should also know that the evidence rules in juvenile court have some unique features. For example, A.R.S. § 8-237 creates a hearsay exception allowing certain out-of-court statements or conduct of a minor to be admitted in juvenile court proceedings. Defense counsel needs to be ready to challenge the reliability and use of such statements — another reason experienced juvenile-specific representation matters.
After an arrest, a juvenile may be released to parents or held at a county detention facility. If your child is detained, the court must hold a detention hearing promptly — generally within 24 hours under the Arizona Rules of Procedure for the Juvenile Court — to decide whether continued detention is necessary or whether the child can go home, with or without conditions.
Similar to an adult arraignment: the judge advises the juvenile of the allegations in the petition and their rights, counsel is confirmed or appointed, and the juvenile admits or denies the allegations.
Defense counsel investigates, reviews disclosure, litigates motions (for example, to suppress statements taken in violation of Miranda), and negotiates. Many cases resolve by plea agreement or diversion. If not, the case proceeds to the adjudication hearing, where the judge decides whether the state has proven the delinquent act beyond a reasonable doubt. If proven, the child is "adjudicated delinquent" — the juvenile equivalent of a conviction.
Disposition is the juvenile analog of sentencing, and the court's options are geared toward rehabilitation. Common outcomes include:
| Disposition | What it means |
|---|---|
| Standard probation | Supervision by a juvenile probation officer, plus conditions like counseling, curfew, school attendance, and community service |
| Intensive probation (JIPS) | Stricter supervision with more frequent contacts for higher-risk youth |
| Restitution and fines | Repayment to victims for losses caused by the offense |
| Treatment programs | Substance-abuse, behavioral-health, or counseling programs, residential or outpatient |
| ADJC commitment | Commitment to the Arizona Department of Juvenile Corrections — the most serious juvenile disposition; juvenile court jurisdiction ends at age 18 |
A juvenile adjudication is not supposed to follow a person for life, but it does not disappear automatically at 18. Arizona provides two main paths to clear a juvenile record:
Setting aside the adjudication — A.R.S. § 8-348. A person who is at least 18 years old, who was adjudicated delinquent or incorrigible, and who has fulfilled the conditions of probation or been discharged from the Department of Juvenile Corrections may apply to the juvenile court to set aside the adjudication. Key features of the statute:
Destruction of records — A.R.S. § 8-349. A separate statute allows qualifying individuals to apply for destruction of their juvenile court and referral records once statutory conditions are met. Whether set-aside, destruction, or both make sense depends on the record and the person's goals — college applications, professional licensing, military enlistment, or employment background checks.
