N.C. Gen. Stat. § 8-19
Whenever any person owns several tracts of land which are contiguous or adjoining, but held under different deeds and different surveys, it may be lawful for any such person to have all such bodies of land included in one common survey by running around the lines of the outer tracts, and thereupon the possession of any part of said land covered by such common survey shall be deemed and held in law as a possession of the whole and every part thereof: Provided, that nothing in this section shall be construed to affect the rights or claims of persons which have already accrued to any part of said land. In all cases where such common surveys are made as directed by this section, the same may be recorded and registered as in cases of deeds, and shall be evidence in like manner.
