Contractor's attorney disputes validity of our Lien stating "it has lapsed due to your failure to enforce it. Under SDCL §5-22-8, a lien may be discharged for 'lapse of the time within which an action to enforce the same may be commenced without such action having been commenced.' SDCL 5-22-7 provides that: All claims to liens under this chapter relating to public improvement contracts shall cease to have any validity or to be binding upon the public body or the contractor under the provisions of this chapter unless an action to enforce the same as hereinbefore provided shall be commenced within thirty days from the acceptance of the work for which the same shall be claimed. ...As of today’s date, A Thru Z has not taken further action to enforce its lien...because A Thru Z has not taken any action to enforce its Public Claim of Lien within thirty (30) days of acceptance of A Thru Z’s work, its Public Claim of Lien has ceased to have any validity under SDCL 5-22-7 and 5-22-8." 1. Is this correct? 2. If so, we were not aware of this requirement to maintain/effectuate the Lien. I would expect that zLien should have advised us accordingly at the time we issued it. Did they and we missed it??
