AZ SB1323

Raises the age of juvenile court jurisdiction from 18 to 21 years old, allowing courts to retain jurisdiction over individuals up to age 21 for delinquent juveniles with state notice of intent to retain jurisdiction.

Updates definitions of "adult," "child," and "juvenile" throughout Arizona Revised Statutes to reflect the new age threshold of 21 instead of 18.

Allows juvenile courts to retain jurisdiction over 17-year-olds adjudicated as delinquent until age 19 if the state files notice of intent at case commencement, with automatic discharge at age 19 unless terminated by court order or department discharge.

Modifies probation periods, treatment services eligibility, and competency determination timelines to align with the expanded juvenile court jurisdiction through age 21.

Makes conforming amendments to criminal charging provisions, discharge requirements, and record destruction timelines to accommodate individuals under 21 remaining in the juvenile justice system.
