In Tennessee, adjoining landowners sometimes end up in court in boundary disputes. There are various reasons that boundary line disputes arise, including: imprecise descriptions in deeds; conflicts between descriptions in recorded plats and deeds to owners of subdivision lots; fences that have been in place for years, but that are not consistent with deed descriptions; and deed overlaps (where, for example, there is not enough land to satisfy the deed descriptions for two adjoining parcels which were once part of the same tract).
Even if a Tennessee court might otherwise resolve a boundary dispute in favor of Landowner A, instead of Landowner B, based strictly on deed descriptions and/or the testimony of a surveyor, Landowner B might still be declared the lawful owner of the disputed land. Why? In Tennessee, if adjoining landowners agree, even verbally, on a boundary line, the agreed boundary line may well become the legally accepted boundary line. Keep in mind that an agreement in this context requires some sort of communication and assent. It is typically not enough for one of the landowners to say simply that the other did not object to a fence, wall, or other boundary marker.
In addition to an agreement between adjoining landowners as to a boundary line, disputed property might be held to be the property of one of the landowners (let’s say Landowner B) based on the doctrine of adverse possession. This might be the case even if the court determines that the relevant deeds establish that the property would otherwise belong to Landowner A.
