Tenn. Code Ann. § 45-10-109

In all judicial proceedings, the reasonable expenses of a financial institution in producing records in response to a subpoena shall be taxed as costs, without regard to the amount of any bond, and in all other instances, the issuer shall pay the financial institution's reasonable expenses incurred in complying with the subpoena. The financial institution shall submit to the issuer, either with the records or within thirty (30) days after delivering the records, a statement as to its charges for preparing and delivering the records. Charges by the financial institution at rates that do not exceed those established by the financial institution’s published fee schedule shall be deemed reasonable unless otherwise determined by the appropriate court after notice and a hearing.
