The Office of Trustee is identified as a County Charter Office in accordance with the Shelby County Charter Amendment of November 2008. Under the amendment, the Trustee may serve two (2) four year terms to perform those duties identified by the state constitution and mandated by the laws of the State of Tennessee. To ensure the faithful performance of duties, the Trustee must be bonded according to T. C. A. § 8-11-103 (PDF). The appropriate amount of the bond is calculated using the amount of revenue collected by the Trustee and is based on financial risk.
