W. Va. Code § 31A-5-5: Regulation and examination of performance of bank services.

No state bank may cause to be performed, by contract or otherwise, any bank services for itself, whether on or off its premises, unless written assurances satisfactory to the commissioner of banking are furnished to him by both the state bank and the party performing such services that the performance thereof will be subject to regulation and examination by the commissioner and any federal supervisory agency to the same extent as if such services were being performed by the state bank on its own premises.
