Mechanic's lien deadlines in Wisconsin: the 2026 guide for subcontractors

If you furnish labor or materials on a Wisconsin project and you don't get paid, a mechanic's lien is how you force the issue. But the right to file expires fast. Here are the deadlines that matter, in plain language.

  1. Preliminary / Pre-Lien Notice

    Many Wisconsin projects require a subcontractor or supplier to serve a preliminary or pre-lien notice early in the job, generally within about 60 days of first furnishing labor or materials, to keep lien rights alive.

    Wis. Stat. § 779.01 et seq.

  2. Record Your Mechanics Lien

    Record your mechanics lien with the county recorder, generally within about 180 days after the last day you furnished labor or materials to the project.

    Wis. Stat. § 779.01 et seq.

  3. Deadline to Enforce the Lien (Lawsuit)

    File a lawsuit to enforce (foreclose) your lien, generally within about 24 months after the lien is recorded, or the lien can expire.

    Wis. Stat. § 779.01 et seq.
