Wisconsin lien deadlines for contractors
Updated · Checked against primary sources
The short answer
In Wisconsin, file a lien claim with the circuit court clerk within 6 months of your last work or materials, after serving a notice of intent at least 30 days before filing. Sue within 2 years of filing. On residential jobs of 4 units or fewer, primes must give the owner a lien notice, and subs and suppliers must serve notice within 60 days of first furnishing.
The deadlines
| Step | Rule |
|---|---|
| Preliminary notice: who | Only on wholly residential projects of 4 or fewer family units. Prime contractors who use subs or suppliers must put the statutory lien notice in the written contract with the owner. Subs, sub-subs and suppliers (everyone except a prime) must serve a notice on the owner. Not required on nonresidential or mixed-use work, projects adding more than 4 units, by laborers employed by a contractor, or by those contracting directly with the owner (other than primes). |
| Preliminary notice: when | Prime: in the written contract, or if there is no written contract, served within 10 days after first labor or materials are furnished. Subs and suppliers: within 60 days after first furnishing labor or materials, in 2 signed copies. (A late sub or supplier notice still gives a lien for work furnished after the owner actually receives it (779.02(3)). A prime that skips its notice loses the lien unless it pays all its subs and suppliers on time.) |
| File or register the lien | Within 6 months from the date the claimant last performed labor or furnished materials, file the claim for lien in the office of the clerk of circuit court for the county where the land is, and serve a copy on the owner within 30 days after filing (779.06(1)). Same deadline for primes and subs. |
| Enforce or perfect it | Within 2 years from the date of filing the claim for lien, bring the action and file the summons and complaint (779.06(1)). |
| Residential jobs | Preliminary notice rules under 779.02 apply only to wholly residential projects of 4 or fewer family units. On nonresidential projects and residential projects over 4 units, no prime or sub notice to owner is required, but the 30-day notice of intent still is. |
Other notices and rules
- Notice of intent to file lien claim (779.06(2)): required of every claimant, served on the owner at least 30 days before filing the claim, whether or not a 779.02 notice was given. Because the claim is due within 6 months, the notice of intent must go out within about 5 months of last furnishing.
- The claim for lien must attach copies of any 779.02 notice and the notice of intent (779.06(3)).

General information from the statutes cited below, checked 2026-09-24. Lien law is strict and details depend on your role and contract. Confirm with a construction lawyer in Wisconsin before relying on a deadline. Read from the official Wisconsin Legislature site (2025 biennium, published 9-4-26). The 2-year enforcement period is in 779.06(1), not 779.10 (779.10 covers the judgment).
Where Pavado comes in
How Pavado builds a CRM around your jobs
Lien rights are usually lost to a calendar, not a court. We build CRMs that start each job's notice and lien clocks from its real start and completion dates and remind you before every deadline, so the rights you earned by doing the work are still there when a customer stops paying.
Instead of bending your shop around someone else's software, we build the system around how your jobs actually move, and connect it to what you already use.
- Your pipeline, your stages. From first call to paid invoice, set up the way your team already works.
- Automations for the busywork. Follow-ups, reminders and handoffs that happen without anyone remembering.
- One record per customer. Calls, quotes, jobs, photos and invoices in one place instead of five apps.
- Connected to your stack. QuickBooks or Xero, Gmail or Outlook, payments and e-sign, plus thousands more through Zapier and an API.
- 1.Book a free demo and walk us through how a job moves today.
- 2.We map the workflow and send a scoped proposal, free.
- 3.We build it, connect your tools and get your team using it.
The first conversation and a scoped proposal are free, and we will tell you early if we are not the right fit.
