According to Right to Financial Privacy Act, the bank is required to notify the customer when someone is requesting account records such as deposition subpoena for records.
No, it isn't. If customer notice is required, the government, not the bank, is required to provide it. The bank is only required to get a certification from the government that it has fulfilled its legal requirements prior to turning over the records. If the feds are demanding financial records, you handle employee records just like you do those of other customers.
