1. When a mechanic's lien is satisfied by payment of the claim, the claimant shall acknowledge satisfaction thereof and, if the claimant neglects to do so for thirty days after demand in writing is personally served upon the claimant, the claimant shall forfeit and pay twenty-five dollars to the owner, general contractor, or owner-builder and be liable to any person injured to the extent of the injury.

2. If satisfaction is not acknowledged within thirty days after service of the demand in writing, the party serving the demand or causing the demand to be served may file for record with the administrator a copy of the demand with proofs of service attached and endorsed and, in case of service by publication, a personal affidavit that personal service could not be made within this state. Upon completion of the requirements of this subsection, the posting shall be constructive notice to all parties of the due forfeiture and cancellation of the lien. Upon the posting of the demand with the required attachments, the administrator shall mail a date-stamped copy of the demand to both parties.
