Construction of Buildings · NAICS 236 · Lien Waiver

A lien waiver is a critical document in building construction, where subcontractors and suppliers on residential and commercial projects often must waive their right to file a mechanics lien to get paid. This form is tailored to construction of buildings (NAICS 236) and covers both conditional and unconditional waivers for progress and final payments. It includes state-specific considerations, such as notarization requirements, and protects your rights while satisfying owners and title companies. Use it to streamline payment on your next building project.

Frequently asked questions

What is the difference between conditional and unconditional lien waiver?

A conditional waiver takes effect only when payment is actually received, while an unconditional waiver is effective immediately upon signing, even if the check bounces. For building projects, always use a conditional waiver until you have confirmed funds.

Do I need to notarize a lien waiver for building construction?

It depends on the state. Some states like Texas require statutory forms and notarization, while others do not. Many owners and title companies request notarization regardless, so our form includes an optional notary block.

Can I waive rights for work not yet paid?

No. A lien waiver only covers the specific amount and work described. You should never sign an unconditional waiver before receiving payment. Our form includes a reservation of rights to protect you for unpaid extras.
