Lien Waiver and Release

A Lien Waiver and Release in the United States waives defined claims, preventing the releasing party from pursuing them later. It records the rental price, deposit, term, maintenance duties, and notice periods between landlord and tenant.

Lien waivers exist in four standard forms recognized across most jurisdictions: conditional waiver on progress payment, unconditional waiver on progress payment, conditional waiver on final payment, and unconditional waiver on final payment. The distinction between conditional and unconditional is critical. A conditional waiver becomes effective only when the claimant actually receives the payment referenced in the waiver. An unconditional waiver is effective immediately upon execution, regardless of whether payment has actually been received.

Several states, including California (Civil Code Section 8132-8138), Arizona (A.R.S. Section 33-1008), and Mississippi, mandate the use of statutory lien waiver forms. Using non-compliant forms in these states may render the waiver unenforceable or fail to extinguish lien rights. The waiver does not eliminate other contractual remedies such as breach of contract claims, stop-work rights, or bond claims on bonded projects.

Property owners and general contractors require lien waivers as a condition of each progress payment disbursement. A developer building a $3 million commercial project collects conditional waivers from the general contractor and all subcontractors before releasing each monthly draw, then obtains unconditional waivers confirming receipt of the previous month's payment. Construction lenders typically require these waivers before funding each draw request under the construction loan agreement.

Title companies require final unconditional lien waivers from all parties in the construction chain before issuing title insurance on newly constructed or renovated properties. Without complete waiver packages, a title exception for potential mechanic's liens remains on the policy, which can prevent sale or refinancing of the property.

Subcontractors and suppliers issue waivers to the general contractor or property owner upon receiving progress and final payments. A plumbing subcontractor who completed $85,000 in rough-in and finish work provides conditional waivers with each payment application, then an unconditional final waiver upon receiving the final retention payment.

Government construction projects governed by the Miller Act (40 U.S.C. Sections 3131-3134) and state Little Miller Acts substitute payment bond claims for lien rights on public property, but waivers still serve to track payment flow and confirm satisfaction of obligations through the contracting chain.

The waiver type must be clearly identified as one of the four standard forms: conditional progress, unconditional progress, conditional final, or unconditional final. Using the wrong type can result in premature release of lien rights before payment is actually received, exposing the claimant to significant financial risk if the payer's check bounces or payment is otherwise dishonored.

Claimant identification must include the full legal name, address, and role (general contractor, subcontractor, material supplier) of the party executing the waiver. The property description should include the street address, legal description, and the property owner's name. The project description or contract reference ties the waiver to the specific scope of work performed.

Payment details must state the exact amount being paid, the billing period covered (the "through date"), and any retention amounts withheld. For conditional waivers, the payment amount represents the condition precedent to the waiver becoming effective. For progress waivers, include the total contract amount, amount paid to date, and remaining balance to provide context within the overall project payment history.

Exceptions and reservations allow the claimant to exclude specific disputed amounts or change orders from the waiver scope. Without an exception provision, the waiver may inadvertently release claims for disputed work. The notarization requirement varies by state. States such as Texas and Michigan require notarized lien waivers, while others accept unnotarized executed forms. Include the date of execution, the claimant's authorized signature, and any state-mandated statutory language required for enforceability.
