Sealing juvenile records may often be more complicated than expungements of records later in life. In order to be a candidate for having juvenile records sealed, one must be 18 years old and have waited 5 years since his or her case had closed, probation ended and the judge deemed him or her rehabilitated.
When a minor is arrested, it is very common for them to become nervous and make incriminating statements. Dealing with police officers is not only a skill children do not learn, it may vary from town to town, race to race and per situation.
When you learn that your child has been arrested, it is natural for an irrational response to take over. Anger, fear and concern take over before rationality, especially when you know little about how the justice system in California treats minors.
