Tex. Ins. Code § 701.152

Information or material acquired under this chapter by an authorized governmental agency is privileged and is not a public record. The information or material is not subject to a subpoena, other than a grand jury subpoena, unless, after reasonable notice to the insurer and agency and a hearing, a district court determines that obeying the subpoena would not jeopardize the public interest and any investigation by the agency.
