Generally, a juvenile crime will stay on your record until successful completion of probation, with exceptions for serious crimes which cannot be sealed until the age of 18 (or 21 if you were committed to the Department of Youth and Community Restoration). The consequences of juvenile convictions are designed to be short-lived. In many cases, if you comply with the terms of probation and demonstrate rehabilitation, then you are entitled by law to have your juvenile charges dismissed, sealed, and expunged (destroyed). Once records are sealed, the proceedings are legally deemed never to have occurred.
