Wisconsin Mechanics Lien Laws

Notice to Owner of intent to lien must be served at least 30 days before filing (non-prime contractors). 6 months from last work. 2 years to enforce.

Step-by-step guide for Wisconsin

1. 1

   Confirm your lien rights

   Verify you hold a valid contract, are properly licensed (if Wisconsin requires it), and that the work was on private property. Public projects require a payment bond claim, not a lien.

2. 2

   Send preliminary notice

   Wisconsin requires a preliminary notice before filing. Missing this notice permanently bars your lien rights.

3. 3

   Track your deadline from last day of work

   Your lien must be recorded within 180 days of your last furnishing of labor or materials. Mark the calendar the day you finish work — this clock does not stop.

4. 4

   Prepare the lien document

   Your lien claim must include: claimant name and address, property owner name, property description (legal description or address), amount claimed, description of labor/materials, and dates of first and last furnishing.

5. 5

   Notarization (not required in this state)

   Wisconsin does not require notarization.

6. 6

   File with the Register of Deeds

   Record your lien with the Register of Deeds in the county where the property is located. Filing fee is typically $30–$50. Request a file-stamped copy for your records.

7. 7

   Serve a copy on the property owner

   Most states require you to mail or personally serve a copy of the filed lien on the property owner within a short window of recording. Check Wisconsin rules for exact timing and method of service.

8. 8

   Enforce by month 24

   If the debt remains unpaid, you must file a lawsuit to foreclose on the lien within 24 months of recording. If you miss this deadline, the lien expires and the cloud on title is removed without payment.
