N.C. Gen. Stat. § 46A-84.5

If a purchaser in a partition sale defaults on the purchaser's bid, any party to the partition proceeding or the officer or person designated to make the sale may at any time petition the court to revoke its order confirming the partition sale. The petitioner for revocation shall serve all parties required to be served under G.S. 1A-1, Rule 5, and, if the purchaser is not a party, serve the purchaser under G.S. 1A-1, Rule 4(j). If the court finds that the purchaser defaulted on the purchaser's bid and is unable to cure the default, the court shall revoke its order of confirmation and order a resale.
