Lien Waiver

A lien waiver, also called a lien release, is a document in which a contractor, subcontractor or supplier confirms payment and gives up its right to file a mechanics' lien for the work covered. In the US, people who improve a property and don't get paid can usually file a lien against that property. A waiver removes that threat for the amount paid.

There are four common types:

• Conditional progress waiver: gives up lien rights for a progress payment, but only once that payment actually clears.
• Unconditional progress waiver: gives up lien rights for work through a set date, effective right away. It should be signed only after payment is received.
• Conditional final waiver: gives up all lien rights once the final payment clears.
• Unconditional final waiver: gives up all remaining lien rights, effective right away.

A common pattern is to collect a conditional waiver with each payment request, then an unconditional waiver for that payment once it has cleared.

Why it matters for lenders

For a construction loan, unpaid trades are a direct threat to the lender's collateral. In some states, mechanics' liens can take priority over the lender's mortgage, sometimes dating back to when work on the project began. A lender that funds draws without waivers may be paying the borrower while the people doing the work go unpaid, and then face their claims later.

Lien waiver rules vary a lot by state. Some states, including California, Texas, Georgia and Arizona, require waivers to substantially follow forms written into state law, and a waiver that doesn't may not be valid. Other states let the parties use their own forms. Timing, notice rules and lien priority also differ. Lenders should use waiver forms reviewed by counsel for each state where they lend, rather than one national template. This is general education, not legal advice.

How it works in practice

Before funding a construction draw, a loan administrator checks the waiver log. The general contractor's payment application lists five subcontractors paid from the last draw. She needs an unconditional progress waiver from each, matching the amounts paid, plus a conditional waiver from the general contractor for the current request. Two waivers are missing and one shows the wrong amount. She holds back that part of the draw until they arrive, then orders a title update to confirm no new liens were filed.

At the final draw, the lender requires final waivers from every trade before releasing retainage. In spreadsheets and email, matching dozens of waivers to the right trade, draw and dollar amount is slow and easy to get wrong. Tying each waiver to the draw and trade it covers makes the gaps easy to see.
