A construction lien – also known as a mechanic’s lien – is a powerful legal tool that allow contractors, subcontractors, and suppliers to secure payment for work performed or materials supplied on a property.

This guide explains what a construction lien is, how lien waivers work, and when you may want to hire an attorney to take action.

Whether you’re a contractor safeguarding your right to payment or a property owner trying to avoid a lien dispute, this page covers the essentials.

What is a lien waiver?

A lien waiver is a legal document used in the construction industry to relinquish the right to file a lien against a property. These waivers are often exchanged when a payment is made—essentially serving as a receipt that confirms the contractor or subcontractor has been paid and will not pursue further claims on the property.

There are two main types of lien waivers:

• Conditional lien waiver: Effective only when payment clears.
• Unconditional lien waiver: Takes effect immediately, regardless of whether the payment is received.

Waivers reduce the risk of double payment for property owners and offer protection for contractors by clarifying payment terms.

Understanding the construction lien form

A construction lien form is the official document filed with the local county recorder’s office to place a lien on a property. The form typically includes:

• Name and address of the lien claimant
• Property owner’s name
• Description of labor or materials provided
• Amount owed
• Legal description of the property
• Dates of work and/or final delivery
• Verification (notarized signature)

Wisconsin imposes strict deadlines on when a construction lien may be filed. Missing these deadlines can invalidate the lien. To ensure all statutory requirements and deadlines are met, it is recommended that an attorney be hired.

Construction lien waivers and releases

Lien waivers and lien releases are sometimes used interchangeably, but they serve different purposes in the lien process:

Lien waiver

A lien waiver is typically signed before or at the time of payment and prevents future lien rights.

Lien release

A lien release is signed after a lien has already been filed and confirms that the claimant has been paid and is voluntarily removing the lien.

Both documents are vital to keeping construction payment chains clean and reducing disputes. For property owners, obtaining signed waivers and releases from all parties before releasing funds is the recommended practice.

When to hire a construction lien attorney

You should consider hiring an attorney in any of the following scenarios:

• You’re a contractor or subcontractor who hasn’t been paid on a project.
• You’re a property owner who’s received a Notice of Intent to file a lien.
• You want to review or draft lien waiver/release documents for a project.
• You’ve been served with a foreclosure or similar action based on a construction lien.
