Construction lien waivers by state

What is a lien waiver?

A lien waiver is a signed document in which a contractor, subcontractor, or supplier gives up (waives) the right to file a mechanic’s lien against a property — usually in exchange for payment. General contractors collect waivers from their subs so they can prove a property is clear of potential liens for work they’ve already paid for.

The four types of lien waiver

Almost every waiver is one of four combinations — conditional vs. unconditional, crossed with progress vs. final. Picking the wrong one is the most common and most dangerous mistake.

Conditional vs. unconditional — the one that bites

A conditional waiver only takes effect once payment actually clears, so it’s safe to exchange before or alongside a payment. An unconditional waiver takes effect the instant it’s signed, whether or not payment has cleared — so it should only ever be signed after payment is confirmed. Sending an unconditional waiver too early is how subs accidentally release rights to money they never received.

This is exactly the step ClearLien automates: it tracks the open conditional waiver and auto-drafts the matching unconditional waiver only once the bill payment clears in QuickBooks — never before.

Do all states require a specific form?

No. About a dozen states mandate specific statutory waiver forms you’re required to use; many others leave the form to the parties, as long as it clearly releases the right lien rights. Because requirements — and deadlines — differ by state and change over time, always confirm the current rules for your project. Use the directory below for state-specific detail.

Retainage changes the math

On a progress waiver, the covered amount should reflect only what’s actually been paid. Withheld retainage has to be excluded — otherwise a sub waives rights to money still being held. ClearLien carves retainage out of progress waivers automatically.
