California Code, Business and Professions Code - BPC § 22351.5

(a) At the time of filing an initial certificate of registration or renewing a certificate of registration that has lapsed, the registrant shall also submit a completed Request for Live Scan form confirming fingerprint submission to the Department of Justice and the Federal Bureau of Investigation, in order to verify that the registrant has not been convicted of a felony.  The clerk shall utilize the Subsequent Arrest Notification Contract provided by the Department of Justice for notifications subsequent to the initial certificate of registration.

(b) If, after receiving the results of the Request for Live Scan, the clerk is advised that the registrant has been convicted of a felony, the presiding judge of the superior court of the county in which the certificate of registration is maintained is authorized to review the criminal record and, unless the registrant is able to produce a copy of a certificate of rehabilitation, expungement, or pardon, as specified in paragraph (2) of subdivision (a) of Section 22351, notify the registrant that the registration is revoked.  An order to show cause for contempt may be issued and served upon any person who fails to surrender a registered process server identification card after a notice of revocation.
