NOTICE TO OWNER OF LIEN RIGHTS — WIS. STAT. § 779.02

Select the notice for the claimant's role. The following is the current language prescribed substantially by Wis. Stat. § 779.02(2)(a)–(b). Fill the date and property description in the non-prime notice. Print the prime notice in at least 8-point bold type, or use capital letters if typewritten, and give the owner a copy of the written contract containing it. Serve two signed copies of the non-prime notice on the owner or authorized agent.

Prime contractor — § 779.02(2)(a):

As required by the Wisconsin construction lien law, claimant hereby notifies owner that persons or companies performing, furnishing, or procuring labor, services, materials, plans, or specifications for the construction on owner's land may have lien rights on owner's land and buildings if not paid. Those entitled to lien rights, in addition to the undersigned claimant, are those who contract directly with the owner or those who give the owner notice within 60 days after they first perform, furnish, or procure labor, services, materials, plans or specifications for the construction. Accordingly, owner probably will receive notices from those who perform, furnish, or procure labor, services, materials, plans, or specifications for the construction, and should give a copy of each notice received to the mortgage lender, if any. Claimant agrees to cooperate with the owner and the owner's lender, if any, to see that all potential lien claimants are duly paid.

Non-prime claimant — § 779.02(2)(b):

As a part of your construction contract, your prime contractor or claimant has already advised you that those who perform, furnish, or procure labor, services, materials, plans, or specifications for the work will be notifying you. The undersigned first performed, furnished, or procured labor, services, materials, plans, or specifications on [date] for the improvement now under construction on your real estate at [legal description, street address or other clear description]. Please give your mortgage lender the extra copy of this notice within 10 days after you receive this, so your lender, too, will know that the undersigned is included in the job.

Part E — Pre-Filing Checklist

Eligibility & contract

☐ Claimant is within Wis. Stat. § 779.01 (contractor, sub, supplier, equipment lessor, design professional)
☐ Property is private; for public works, review the separate bond and remedy provisions of § 779.14
☐ No contract term requires a claimant to waive a lien or payment-bond claim before that claimant is paid (§ 779.135(1))

Preliminary notice (§ 779.02)

☐ For an applicable prime contractor: statutory notice included in the written owner contract; if there is no written contract, served separately within 10 days after first qualifying furnishing
☐ For an applicable non-prime claimant: exact statutory notice served in two signed copies within 60 days of first qualifying furnishing
☐ If ATCP 110.025 applies, its verbatim lien-waiver notice was given as a separate, retainable document before the home-improvement contract; the buyer's acknowledgement was retained
☐ Proof of service retained under the service methods in Wis. Stat. § 779.01(2)(e)

Notice of Intent to File (§ 779.06(2)) — Part A-2

☐ Notice prepared with nature of claim, amount, property description
☐ Served on owner at least 30 days before filing lien claim
☐ Service method and proof satisfy Wis. Stat. § 779.01(2)(e)
☐ Proof of service retained; § 779.06(2) does not itself impose a general affidavit requirement

Claim for Lien (Part B)

☐ Itemized statement of labor and materials with dates
☐ All credits applied (just and true account)
☐ Signed by claimant or attorney; verification is not required under § 779.06(3)
☐ Copies of every applicable § 779.02 notice and the § 779.06(2) notice attached to the filed claim

☐ Claimed amount is limited to eligible work, labor, services, materials, plans, or specifications used or consumed for the improvement; any fees sought separately have a legal basis
☐ Each signed waiver reviewed for its actual scope under § 779.05(1); § 779.135(1) voids a prepayment-waiver requirement in the contract, not the signed waiver itself

Documentation

☐ Itemized invoices and payment ledger
☐ Daily reports, delivery tickets, time records, photographs
☐ Title report identifying owner of record and prior encumbrances

Real estate documents transfer ownership, define who can use a property, and record agreements between buyers, sellers, landlords, and tenants. Deeds, purchase agreements, leases, and easements have to be drafted to meet state recording requirements, and mistakes show up at closing or years later in title disputes. Good real estate paperwork moves transactions forward quickly and avoids the kind of problems that only surface when it is time to sell or refinance.
