Tennessee Code Title 29. Remedies and Special Proceedings § 29-18-130

(2)(A) If the defendant prays an appeal, then the defendant must execute bond, or post either a cash deposit or irrevocable letter of credit from a regulated financial institution, or provide two (2) good personal sureties with good and sufficient security in the amount of one (1) year's rent of the premises, conditioned to pay all costs and damages accruing from the failure of the appeal, including rent and interest on the judgment as provided for in this section, and to abide by and perform whatever judgment may be rendered by the appellate court in the final hearing of the cause.

(B) The plaintiff is not required to post a bond to obtain possession if the defendant appeals without complying with this subdivision (b)(2). The plaintiff is entitled to interest on the judgment, which accrues from the date of the judgment if the defendant's appeal fails.
