Your questionnaire is probably a replication of the steps provided within either the OCC examination manual or FDIC manual. You have to remember, their questionnaires cover the Right to Financial Privacy Act which encompasses more than the one form you are reviewing. Actually, if you reference either of the publications I cite, they reference the section of code from within the RFPA that the question aligns with. Basically, your questionnaire is not made for the review you are conducting.
Prior to an agent being able to serve a third party summons (which is the form you are looking at) they are supposed to be sending a notification of third party summons to the taxpayer(s) as required by IRC 7602(c). Thankfully, IRS compliance with their own procedures is someone else's problem... I am led to believe they are sending notifications based on their procedures.
