N.D. Cent. Code § 35-01-21: Lien dependent on possession - Voluntary restoration of property extinguishes lien

The voluntary restoration of property to its owner by the holder of a lien which is dependent upon possession extinguishes the lien as to such property unless otherwise agreed by the parties, and notwithstanding any such agreement, extinguishes it as to creditors of the owner and persons subsequently acquiring title to the property, or a lien thereon, in good faith and for a good consideration.
