Tenn. Code Ann. § 66-27-314

The existing physical boundaries of a unit or the physical boundaries of a unit reconstructed in substantial accordance with the original plats and plans of the unit become its boundaries rather than the metes and bounds expressed in the deed or plat or plan, regardless of settling or lateral movement of the building, or minor variance between boundaries shown on the plats or plans or in the deed and those of the building. This section does not relieve a unit owner of liability in case of the owner's willful misconduct nor relieve a declarant or any other person of liability for failure to adhere to the plats and plans.
