    Understanding Iowa Requirements

    Iowa requires contractors, subcontractors, and material suppliers to file a MNLR Filing (Mechanic’s Notice and Lien Registry) to preserve their mechanics lien rights. Under § 572.13, claimants must send this notice within 10 days from first furnishing to remain eligible to file a lien if payment disputes arise.

    Failing to send a timely MNLR Filing (Mechanic’s Notice and Lien Registry) in Iowa can result in the complete loss of your right to file a mechanics lien. This makes compliance with the 10 days from first furnishing deadline one of the most critical administrative tasks for any construction project in the state.
