N.D. Cent. Code § 28-20-14

Whenever an appeal from any judgment is pending and the undertaking requisite to stay execution on such judgment has been given and the appeal perfected as provided in this title, the court in which such judgment was recovered, on motion after notice to the person owning the judgment, may direct the clerk to make an entry on the judgment docket that the judgment is secured on appeal, and thereupon it, during the pendency of the appeal, ceases to be a lien on the real property of the judgment debtor as against purchasers and mortgagees in good faith and for value.
