If execution on a judgment rendered in any court of record in this state or a transcript of which has been filed as provided in W.S. 1-17-306(a) is not issued within five (5) years from date of the judgment or if five (5) years intervene between the date the last execution issued on the judgment and the time of issuing another execution thereon, the judgment is dormant and ceases to operate as a lien on the estate of the judgment debtor.
