A lien on real estate arising under the provisions of section 49-86 shall not continue in force as a lien for a longer period than fifteen years after the date thereof unless within said period an action on the bond in connection with which the notice of lien was filed has been prosecuted to effect and a judgment lien against the surety filed according to law. All liens on real estate which have expired under the provisions of this section shall be deemed dissolved and the real estate shall be free from any lien or encumbrance by reason of the same and the town clerk of the town in which the real estate is situated shall, upon the request of any person interested, discharge such lien of record by recording a discharge of lien in the land records.
