The procedure and organization of the juvenile court system is different from the adult system. After committing an offense, juveniles are detained rather than arrested. Next, a petition is drawn up which outlines the jurisdiction authority of the juvenile court over the offense and detained individuals, gives notice for the reason for the court appearance, serves as notice to the minor's family, and also is the official charging document.

Once in court, the juvenile case is adjudicated, and a disposition is handed down. Records from juvenile courts are sealed documents, unlike adult records which are accessible by anyone under the Freedom of Information Act. Like diversion, this measure is designed to protect the juvenile so that one mistake does not follow the juvenile for life. Juvenile records may also be expunged upon the juvenile's eighteenth birthday provided the juvenile has met certain conditions, such as good behavior. Juvenile court procedure is also far less formal than adult court procedure.

The disposition of a juvenile case is based on the least detrimental alternative, so the legacy of parens patriae is still evident. However, one major controversy in juvenile dispositions is the use of indeterminate sentencing, which allows a judge to set a maximum sentence. In such cases, juveniles are monitored during their sentences and are released only when the judge is satisfied that they have been rehabilitated or when the maximum time has been served. Critics argue that this arrangement allows the judge too much discretion and is, therefore, not the least detrimental punishment.
