Cal. Civil Code § 1786.28

(a) Each investigative consumer reporting agency that collects, assembles, evaluates, compiles, reports, transmits, transfers, or communicates items of information concerning consumers which are matters of public record shall specify in any report containing public record information the source from which this information was obtained, including the particular court, if applicable, and the date that this information was initially reported or publicized. (b) A consumer reporting agency which furnishes a consumer report for employment purposes and which for that purpose compiles, collects, assembles, evaluates, reports, transmits, transfers, or communicates items of information on consumers which are matters of public record and are likely to have an adverse effect upon a consumer’s ability to obtain employment shall in addition maintain strict procedures designed to insure that whenever public record information which is likely to have an adverse effect on a consumer’s ability to obtain employment is reported it is complete and up to date. For purposes of this paragraph, items of public record relating to arrests, indictments, convictions, suits, tax liens, and outstanding judgments shall be considered up to date if the current public record status of the item at the time of the report is reported.
