Order your CA Dept of Justice Live Scan criminal record (use Google for a listing of outlets everywhere in the State). There is no need to guess whether any record is being reported when you can quickly, cheaply and easily obtain a copy of your record.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
Likely this will never show on background check, unless it is run by law enforcement. You can go to Juvenile Court in your County to view your record.
