Which legal process usually involves preliminary investigations in juvenile cases?

The legal process that typically involves preliminary investigations in juvenile cases is the intake process. During intake, a probation officer or intake officer evaluates the case, gathers information, and assesses the juvenile's situation. This step is crucial as it determines how the case will proceed, whether it will go to court, or if alternative measures, such as counseling or community service, may be more appropriate. The intake process allows for a comprehensive understanding of the juvenile's background and the circumstances surrounding the alleged offense, which is essential for making informed decisions regarding their treatment and rehabilitation.
