The lien acquired under § 8.01-501 on intangibles shall cease whenever the right of the judgment creditor to enforce the judgment by execution or by action, or to extend the right by motion, ceases or is suspended by a forthcoming bond being given and forfeited or by other legal process. Furthermore, as to all such intangibles the lien shall cease upon the expiration of the following periods whichever is the longer: (i) one year from the return day of the execution pursuant to which the lien arose, or (ii) if the intangible is a debt due from, or a claim upon, a third person in favor of the judgment debtor or the estate of such third person, one year from the final determination of the amount owed to the judgment debtor.
