What it means
In construction, anyone who supplies labour or materials may have a legal right to place a lien on the property if they are not paid. A lien waiver is the written release of that right, usually for a stated amount and a stated period.
Owners and lenders ask for waivers before releasing funds, because unpaid subcontractors can otherwise claim against the property even when the owner has already paid the main contractor. The waiver breaks that chain of risk.
Waivers come in several types. A conditional waiver takes effect only when payment is actually received, while an unconditional waiver takes effect when signed.
They can also cover a progress payment or the final payment. Payment applications typically net off retainage, which is a percentage of each bill held back until the work is finished.
The waiver should match the amount actually paid, so retainage is not waived until it is released. Careful teams collect waivers from every tier of the supply chain, including suppliers to subcontractors.
Forms and rules differ by location, so some places prescribe the exact wording. Lenders in particular treat waivers as part of their draw process.
Before each advance, the bank's inspector confirms progress, and the loan administrator checks that waivers match the payment applications. Missing or mismatched forms are one of the most common reasons a draw is delayed.
In practice
Real-world examples.
Example
A homeowner paying a kitchen remodelling contractor $30,000 asks for an unconditional final waiver when the last cheque is handed over. The owner then knows that the cabinet supplier cannot later claim against the house. The signed form goes into the closing file in case a buyer or lender asks for proof later.
Example
A bank funding a $5,000,000 apartment project releases each monthly draw only when it has waivers from the general contractor and the main subcontractors. This protects its security over the building. If a waiver is missing, the bank holds back that part of the draw until the paperwork arrives.
Example
A subcontractor on a school project signs a conditional waiver for $45,000 in advance of payment. The waiver becomes effective only when the funds clear, so the subcontractor keeps its lien rights until it is paid. The general contractor needs the signed form to pass on to the owner, which gives the subcontractor leverage to be paid promptly.
Formula
Calculation
Amount released = Progress billing - Retainage
Suppose a subcontractor bills $100,000 for the month and the contract holds back 10% retainage. Retainage = 100,000 x 0.10 = $10,000, so the payment released = 100,000 - 10,000 = $90,000. A conditional progress waiver for $90,000 is signed. If two earlier payments of $90,000 each were also made, the waiver acknowledges cumulative receipts of 90,000 + 90,000 + 90,000 = $270,000. Matching the waiver amount to the cash actually paid is the key control. If the waiver said $100,000 while only $90,000 was paid, the subcontractor would have released $10,000 it had not received, and the retainage would be at risk.Case study
Seen in the real world.
Summit Build is an illustrative, fictional developer constructing a $2,400,000 office fit-out. Early on, it paid its main contractor without collecting waivers from subcontractors. A roofing subcontractor then claimed it had not been paid $80,000 by the main contractor and filed a lien on the building.
The developer had to pay the claim again to clear the title for its lender. Afterwards it changed its process so that no payment is released until waivers are in hand for the previous month. The story is invented, but double payment is a common outcome of missing waivers.
The developer's lawyer also noted that the check on waivers should go down the supply chain. After the dispute, Summit began asking main contractors to list every supplier who delivered more than $5,000 of materials, and collected a waiver from each.
Watch out
Common mistakes.
- Signing an unconditional waiver before the money has arrived. The right to lien is given up even if the cheque later bounces.
- Waiving the full contract value in a progress waiver. The waiver should cover only amounts actually paid.
- Assuming one waiver covers everyone. Each party that can claim needs to sign its own, including suppliers and sub-subcontractors who may be unknown to the owner.
Questions
People also ask.
What is the difference between conditional and unconditional?
A conditional waiver depends on receiving payment, whereas an unconditional waiver applies immediately.
Does a waiver affect the right to be paid?
No, it gives up the right to claim against the property, not the right to sue for the money owed. The contractor can still pursue the person who contracted with it through ordinary legal action.
Who asks for lien waivers?
Property owners, lenders and general contractors request them from everyone who has worked on a project. Title insurers may also ask for them before issuing cover on a finished building.
