A property is described in a deed in three basic ways: Metes and Bounds; Subdivision and Lot; and Section, Township, and Range. The first two are common in Tennessee whereas the third is not (it isn’t unheard of, but not common).
Subdivision and Lot descriptions do not require a surveyor to write them. However, a metes and bounds description does. Metes and bounds are quite literally the measurements and boundary described. Things like: “North 20 feet to a rock in the creek,” ” N24°E 16 chains 27 links to the sourwood where the old gray mare stands,” or “16 paces to an X in a stone.”
