N.C. Gen. Stat. § 156-115: Warranty in deed runs to purchaser who pays assessment.

Where the land assessed by drainage commissioners under the provisions of this Article has been purchased since the making of the assessment by a purchaser for value without notice under a deed of general warranty, and said purchaser pays to the sheriff the amount of said drainage assessment, which is a lien on the land purchased, then such purchaser who pays the said drainage assessment shall have a right of action against the warrantor of his title under the covenant of general warranty contained in his deed for the recovery of the amount paid. (1919, c. 282, s. 3; C.S., s. 5371.)
