Every state has laws establishing a system of juvenile justice courts, outlining their purposes and procedures, and defining the limits of their powers. The names of the courts with juvenile delinquency jurisdiction vary by state and include District Court, Superior Court, Circuit Court, County Court, Family Court, Probate Court, and others.
