Tenn. Code Ann. § 21-1-405

It is no objection to the execution of a decree rendered against a defendant that it was founded on a bill taken for confessed, without personal service; but the court may require the complainant to give sufficient security, in such sum as the court deems proper, to abide by and perform such order touching the restitution of property, or repayment of money, as the court may and should make, upon the defendant subsequently setting aside the decree, and successfully resisting the complainant's suit.
