How to File a Mechanics Lien in Wisconsin
Step 1 — Confirm you have lien rights in Wisconsin
Wisconsin's recorded rules cover general contractors, subcontractors and suppliers (Wis. Stat. § 779.06). Each of those roles has its own filing window — see Step 3. Wisconsin rule detail: Sub/supplier must serve 'Notice to Owner' within 60 days of first furnishing. No notice = no lien rights for work done before the notice.
Step 2 — Send the Wisconsin preliminary notice
Wisconsin requires a preliminary notice 60 days, notice of intent (Wis. Stat. § 779.14). It is a precondition, not a formality. It must reach Circuit Court Clerk and Owner and Prime Contractor and Surety and Prime Contractor and Contractor / Owner (personally liable). Delivery: Certified Mail, Return Receipt Requested. Wisconsin rule detail: Prime must file claim for lien within 6 months of last furnishing of labor or materials.
Step 3 — Your Wisconsin filing deadline
Wisconsin sets the window by claimant role: • General contractors: within 6 months of your last day of work or materials. • Subcontractors and suppliers: within 6 months of your last day of work or materials. The clock runs from last date of furnishing — not your invoice date. Punch-list and warranty callbacks generally do not restart it. Wisconsin rule detail: File claim for lien within 6 months. Must have served preliminary notice on owner first.
Step 4 — Prepare and record the lien in Wisconsin
Record in the county where the property sits, under Wis. Stat. § 779.18. The document must identify the property, the owner of record, the amount actually owed, and what you furnished. Overstating the amount can void the claim outright. Wisconsin rule detail: File suit to enforce lien within 2 years of recording.
Step 5 — Serve the recorded Wisconsin lien
Wisconsin requires service on Circuit Court Clerk and Owner and Prime Contractor and Surety and Prime Contractor and Contractor / Owner (personally liable). Use Certified Mail, Return Receipt Requested and keep the receipt. In many states an unserved lien is unenforceable even though it appears on title. Wisconsin rule detail: Written notice within 90 days of last furnishing on public works projects. No lien on public property in Wisconsin.
Step 6 — Enforce before the Wisconsin deadline expires
You must sue to foreclose within 2 years (filing) (40 U.S.C. § 3133(b)(2)). Miss it and the lien expires and title clears, leaving only a contract claim. Wisconsin rule detail: File suit on payment bond within 6 months of last furnishing.
Retainage rules that affect your Wisconsin claim
Wisconsin treats retainage on its own schedule (Wis. Stat. § 66.0901), so money still held back may have a different due date than your progress billings. Wisconsin rule detail: Second-tier claimants only. No notice = no bond claim.
Other Wisconsin requirements that void liens
• File no sooner than 90 days AND no later than 1 year. • Prime must pay sub within 7 days of receiving payment from owner. Interest at 1%/month on amounts wrongfully withheld. • Retainage released within 30 days of substantial completion on public contracts. 10% maximum retainage. • Public prompt payment: prime must pay sub within 7 days of receiving payment from public owner. Interest at 1%/month on amounts wrongfully withheld.
Frequently Asked Questions
How long do I have to file a mechanics lien in Wisconsin?
Wisconsin requires the lien to be recorded within 6 months, measured from last date of furnishing. The exact window depends on your role — general contractors: within 6 months of your last day of work or materials.
Do I need to send a preliminary notice before filing in Wisconsin?
Yes. Wisconsin requires a preliminary notice 60 days (notice of intent). Failing to send it on time generally forfeits your lien rights entirely, regardless of how much you are owed.
Where do I file a mechanics lien in Wisconsin?
File with the county recorder's office in the county where the property is located. Filing in the wrong county does not preserve your deadline, and re-filing in the correct county after the deadline will not save the claim.
What happens if I miss the Wisconsin filing deadline?
Your lien rights are extinguished. Wisconsin courts do not grant extensions for missed mechanics lien deadlines. You would be left with a breach-of-contract claim against whoever hired you, which carries no security interest in the property and is far harder to collect.
How long does a mechanics lien last in Wisconsin?
Once recorded, you must file suit to enforce within 2 years (filing). If you do not, the lien expires automatically and no longer clouds the property's title.
