When access to financial records is obtained pursuant to section 3414(b) of this title (emergency access), the Government authority shall, unless a court has authorized delay of notice pursuant to subsections (a) and (b), as soon as practicable after such records are obtained serve upon the customer, or mail by registered or certified mail to his last known address, a copy of the request to the financial institution together with the following notice which shall state with reasonable specificity the nature of the law enforcement inquiry:

Any memorandum, affidavit, or other paper filed in connection with a request for delay in notification shall be preserved by the court.
