A minor arrested for a misdemeanor may have the arrest record and records sealed under certain circumstances.
A minor arrested for a misdemeanor may have the arrest record and records sealed if (Penal Code 851.7.):
Some misdemeanor crimes are not eligible for this relief including arrests for registerable sex offenses, some drug offenses, or traffic offenses (Penal Code 851.7(e)). If a court grants relief, the records will be sealed and the proceedings will be deemed never to have occurred (Penal Code 851.7(b)). Section 851.7 relief doesn’t apply to minors who are taken into temporary custody under Welfare & Institutions Code section 625 then released without further proceedings.
