    Understanding Minnesota Requirements

    Minnesota requires contractors, subcontractors, and material suppliers to file a Preliminary Notice to preserve their mechanics lien rights. Under § 514.011, claimants must send this notice within 10 days (residential) to remain eligible to file a lien if payment disputes arise.

    Failing to send a timely Preliminary Notice in Minnesota can result in the complete loss of your right to file a mechanics lien. This makes compliance with the 10 days (residential) deadline one of the most critical administrative tasks for any construction project in the state.
