Sheriffs receive fees from the public for services they perform. However, pursuant to T.C.A. § 8-24-103(a)(2), the sheriff must pay over to the trustee, on a monthly basis, all fees, commissions, and charges collected by the sheriff’s office during the month. Because the sheriff is no longer on the “fee system,” it is the duty of the county legislative body to make the necessary appropriation and pay to the sheriff the authorized expenses fixed by law for operating of the sheriff's office, direct from the county trustee in 12 equal monthly installments, irrespective of the fees earned by the sheriff. T.C.A. § 8-24-103(a)(1). Pursuant to T.C.A. § 8-20-120, the county legislative body is required to fund the operations of the sheriff's office. Accordingly, the county legislative body is authorized to appropriate moneys to purchase all necessary equipment for use by the sheriff for preservation of the peace and for the service and execution of all process, criminal and civil, and to pay the salaries of deputy sheriffs appointed pursuant to the provisions of Title 8, Chapter 20. T.C.A. § 5-9-101(21). All necessary books, stationery, office equipment, stamps, and supplies of all kinds used in the conduct of the sheriff’s office are to be furnished and paid for by the county. T.C.A. § 8-22-107(a). Additionally, the sheriff is authorized to include in the sheriff's expense account, as part of the expenses of the office, the necessary cost of arresting criminals, of furnishing and operating the county jail and maintaining the state and county prisoners therein, and all other necessary and legitimate expenses incurred in the proper and efficient administration of the sheriff’s office. T.C.A. § 8-22-110(a).
