WI AB1075

Raises the age of juvenile court jurisdiction from 17 to 18, meaning 17-year-olds alleged to have violated criminal laws, civil laws, or municipal ordinances would be processed through the juvenile justice system rather than adult criminal court

Creates a sum sufficient appropriation for the Department of Children and Families to reimburse counties for costs associated with 17-year-olds in the juvenile system, beginning January 1, 2026

Amends statutory definitions of "adult," "child," "juvenile," and "minor" throughout Wisconsin law to reflect the change from age 17 to age 18 as the threshold for adult status in criminal proceedings

Applies to violations allegedly committed on or after the effective date of the legislation

Maintains existing exceptions allowing certain serious juvenile offenders to be waived to adult court under existing provisions
