California Code, Insurance Code - INS § 791.03

No insurance institution, agent or insurance-support organization shall use or authorize the use of pretext interviews to obtain information in connection with an insurance transaction; provided, however, that a pretext interview may be undertaken to obtain information from a person or institution that does not have a generally or statutorily recognized privileged relationship with the person to whom the information relates for the purpose of investigating a claim where there is a reasonable basis for suspecting criminal activity, fraud, material misrepresentation or material nondisclosure in connection with a claim.
