Wisconsin Lien Waiver Requirements and FAQs

Whether you’re a general contractor (GC), subcontractor, or property owner, understanding Wisconsin lien waivers is crucial. These essential documents function as receipts acknowledging payment up to a specific amount, thereby waiving the party’s right to file a lien against the property for that amount. While the concept is straightforward, the practical application of lien waivers can be complex.

Several types of lien waivers exist, each requiring submission at specific times during a project. (For a deeper dive into lien waiver basics, refer to The Ultimate Guide to Construction Lien Waivers for Subcontractors.) Moreover, lien waiver requirements vary by state, with each jurisdiction setting its own rules regarding valid forms, contents, and enforcement.

Understanding these nuanced requirements is important for subcontractors to maintain compliance, prevent payment disputes, and protect their financial interests. So grab your hard hat, and let’s dive into the world of Wisconsin lien waivers!

Wisconsin

Wisconsin Lien Waiver Overview

Wisconsin's lien waiver laws are complex, even though the state is one of 38 without a mandated form. This means parties can include anything they want in a Wisconsin lien waiver. And because many lien and lien-related statutes favor the owner, even small mistakes can invalidate a waiver and unintentionally relinquish lien rights. Therefore, construction teams in Wisconsin must be meticulous and adhere strictly to the rules—easier said than done.

Wisconsin law has seemingly contradictory provisions:

  • Section 779.135 prohibits contractual provisions that require laborers to waive their lien rights (or claims against a payment bond) before they've been paid for work, services, materials, plans, or specifications. 
  • However, Section 779.05 states that any signed lien waiver is "valid and binding," regardless of payment or timing. This means a laborer could technically sign away their rights before even starting work or providing materials, even if no such contractual provision exists.

Remember this difference: While contractual provisions waiving your lien rights aren’t allowed here, Wisconsin lien waivers are binding whenever you sign them. Ultimately, it’s important to review the lien waiver form and corresponding job contract to make sure your lien rights stay protected through fair payment terms. 

Here are some other key considerations when handling lien waivers in Wisconsin:

  • Within 10 days after work begins, materials are furnished, or plans are procured under the authority of the GC, laborers need to provide either the owner or authorized agent with the Notice to Owner, Lender, and Supplier. The text must follow the language in Section 779.02 “substantially” to be valid. This document acts as a safeguard to fair, timely payment. 
  • Lien waivers need to be extremely clear-cut to support GCs, subs, and suppliers in the state of Wisconsin. Statutes note that “any ambiguity in such document shall be construed against the person signing it,” putting owners in the driver’s seat in case of a dispute.

Wisconsin Lien Waiver FAQs

Does Wisconsin have a specific lien waiver form that must be used?

Wisconsin doesn’t provide parties with a specific, statutory lien waiver form. The contents can include anything owners want—including language that takes away important leverage to get paid. Read the contract and corresponding lien waiver forms carefully, and advocate for fair payment language if necessary.

What are the specific requirements for a lien waiver to be valid in Wisconsin?

While Wisconsin lien waivers are largely unregulated, there are still some important rules to follow to make sure they’re valid documents:

  • They should clearly state the amount being waived and the property to which they apply, 
  • They must be signed by the party waiving their lien rights, and
  • They must be preceded by a Notice to Owner, Lender, and Supplier within 10 days after labor begins or materials are purchased.
When must lien waivers be exchanged in Wisconsin?

Wisconsin statutes don't specify when lien waivers must be exchanged. While a contract cannot force someone to give up their lien rights before payment (779.135), the state also deems signed lien waivers "valid and binding" (779.05) regardless of payment. This creates a tricky situation: Even though a contract can't require a pre-payment waiver, if someone does sign one (even without a contractual requirement), it's considered legally binding because of 779.05.

This means that while technically, a Wisconsin lien waiver can be signed at any time, signing one before payment is extremely risky and can result in losing your lien rights without getting paid. Do not sign a lien waiver before you have been paid.

When exchanging both conditional and unconditional waivers, we recommend following these timing rules, recognized as industry best practices:

  • Conditional lien waivers, which are only effective once payment is received, are exchanged with progress payment applications.
  • Unconditional lien waivers become binding upon signature, even if payment hasn’t been received. These documents should only be submitted following payment for Wisconsin construction jobs.

Can lien waiver provisions be added to the contract in Wisconsin?

In Wisconsin, any contractual provisions that ask contractors to waive their lien rights or claim them against a payment bond before payment for their work, services, or materials furnished are not allowed. This move protects construction teams from agreements that eliminate their leverage for fair payment. 

What should I do if there's a dispute over a lien waiver in Wisconsin?

Lien waiver disputes can be messy and delay any late payments even further. Wisconsin courts judge lien waivers by their intent; any ambiguous language is often interpreted in favor of the owner

Keeping this in mind, read over your lien waiver form and corresponding job contract if you enter into a dispute. Try to mediate with the other party directly. If this doesn’t pan out, consider consulting with a construction law attorney who is familiar with Wisconsin lien laws.
