Lien Waiver Requirements by State

The short answer: In most states you can write your own lien waiver, as long as it is clear. Twelve states require an exact statutory form, and a waiver that does not match can be void. About ten states also require a notice of intent before you can file a lien. The table below shows where your state lands, with the statute for each rule.

Lien rules are set state by state, and two of them decide how you handle a waiver: whether your state mandates a specific waiver form, and whether it requires a pre-lien notice of intent before you can file. Get either wrong and a waiver you signed, or a lien you tried to file, can fall apart.

The table covers all fifty states plus Washington, D.C. Each rule links to the controlling statute so you can confirm it yourself.

How to read this table

Statutory lien-waiver form. In the twelve states marked "Required," you cannot write your own waiver. The state prescribes the exact wording, and a non-conforming waiver can be thrown out when you need it most. In every other state, a clear conditional or unconditional waiver works, signed at the right time.

Pre-lien notice of intent. In the states marked "Required," you have to send a notice of intent to lien before you can file the lien itself, often on a strict deadline. It is also worth sending in states where it is optional, because it frequently gets you paid without filing.

These are the two rules that change most by state. Deadlines for filing the lien itself, preliminary notices earlier in the job, and other requirements vary too, so confirm the full picture for your state and project.
