California

Persons who serve more than 10 papers a year are required to be registered in the county in which they operate. Registration is valid statewide. Applicants must be a resident for one year immediately preceding filing. Each applicant is required to post a $2,000 bond or cash deposit. No testing or education required. Licensed private investigators, although exempt from the registration requirement, would probably not be empowered to serve bank levies and similar documents without being registered in view of the statutory language requiring that a registered process server serve those documents.
