Tenn. Code Ann. § 62-18-127: Duty to research common boundaries

A professional land surveyor shall search the land records of the land to be surveyed filed in the register of deeds office and obtain the deeds of record of all the adjoining landowners as it pertains to the common boundaries. The professional land surveyor shall have the additional responsibility to utilize documents of public record or unrecorded documents or plats supplied to the surveyor at the time of the survey to resolve any discrepancies between the subject land and any adjoining lands. Evidence found from these sources shall be carefully compared with that located or found in the field survey in order to aid in the establishment of the original boundaries of the land being surveyed. It is not the intent of this section to require the professional land surveyor to research the title or encumbrances on the land involved.
