Updated June 2026 | Private Projects: N.C. Gen. Stat. § 44A-12(c) 

A lien waiver is a signed document in which a contractor, subcontractor, supplier, or other potential claimant releases some or all of their mechanics lien rights in exchange for payment or the promise of payment. Lien waivers are routine in construction payment administration. Done right, they’re a normal part of closing out a pay application. Done carelessly or under pressure, they can extinguish lien rights on amounts that haven’t been paid and leave you with no practical remedy.

North Carolina law, effective March 1, 2022, provides significant statutory protection under § 22B-5. Understanding those protections and their limits is what separates a lien waiver that’s safe to sign from one that quietly gives away more than the payment justifies.

Scope: The lien rights being waived are mechanics lien rights under NCGS Chapter 44A for private construction projects.

Quick Facts

• Statutory forms: None — parties draft their own
• Conditional and unconditional waivers: Both recognized; conditional is the safer form for progress payments
• Three things NC law prohibits: Waivers as a condition of getting a contract; overbroad progress payment waivers; final waivers demanded in exchange for progress payments
• Label doesn’t control: Calling a waiver “unconditional” does not override the § 22B-5 prohibitions
• Key statute: NCGS § 22B-5 (effective March 1, 2022)

The Two Types of Lien Waivers

Conditional lien waiver. The release of lien rights is conditioned on actual receipt and clearance of the specified payment. If the check bounces or the payment never arrives, the condition has not been met and lien rights are fully preserved. This is the appropriate form for progress payments: you are releasing rights only for money you are actually receiving, and only when you actually receive it.

Unconditional lien waiver. The release takes effect when the document is signed, without waiting for payment to clear. In most states, signing an unconditional waiver before the check clears immediately extinguishes lien rights regardless of what happens next. In North Carolina, § 22B-5(b) limits the damage in the progress-payment context — an unconditional waiver that purports to cover more than the actual payment amount is unenforceable as to the excess — but the safest practice is to use conditional waivers for progress payments and reserve unconditional waivers for final payment after the check clears.

Progress payment waiver. Covers a specific payment for a defined period — a pay application, a draw, a month’s work. Should be precisely scoped to the amount being paid and the period it covers.

Final payment waiver. Covers all remaining lien rights under the contract, releasing any claims not previously waived. Appropriate only when final payment has been received, the check has cleared, and all disputes are resolved.

North Carolina’s Three Statutory Prohibitions

§ 22B-5 imposes three specific prohibitions. Each is independently void and unenforceable — a provision can violate one, two, or all three at once.

1. Waiver As a Condition of Getting the Contract

Any contract provision requiring a potential claimant to waive lien rights in advance as a condition of executing or being awarded the contract is void and unenforceable (§ 22B-5(a)). You cannot be required to surrender lien rights before you have done any work or received any payment.

If a contract you are asked to sign includes a blanket lien waiver or requires you to sign one as a condition of award, that provision has no legal effect in North Carolina. You do not need to negotiate around it, it is simply void.

2. Overbroad Progress Payment Waivers

A provision requiring a lien waiver as a condition of receiving a progress payment is invalid if the waiver attempts to cover more lien rights than what corresponds to the specific payment being made (§ 22B-5(b)). You can be asked to waive rights for amounts you are actually receiving. You cannot be required to waive rights for amounts not yet paid as a condition of receiving an interim payment.

This applies regardless of how the waiver is labeled. “Unconditional” language does not override the statute.

3. Final Waiver in Exchange for a Progress Payment

A provision requiring a broad or final waiver (one releasing all lien rights for the project) as a condition of a progress payment is void (§ 22B-5(c)). Final waivers can be requested and enforced at the end of the project when all payments have been made. They cannot be demanded in exchange for a check that covers only part of the contract.

What Every Nc Lien Waiver Should Include

North Carolina has no statutory form. A waiver must be in writing and signed, but the statute does not specify required elements. Because scope disputes are the most common lien waiver problem, precision is worth the extra lines:

• Names of the parties — the claimant signing the waiver and the party making the payment
• Project identification — project name, address, or description sufficient to identify the specific job
• Contract description — the subcontract, purchase order, or contract under which the work was performed
• Scope of the release — the specific payment amount being waived (for progress waivers) or a statement that all amounts through final payment are released (for final waivers)
• Through date or pay period — the period of work being covered; verify this matches your pay application
• Conditionality clause (for conditional waivers) — language expressly conditioning the release on receipt and clearance of the specified payment
• Signature and date — signed by the claimant or a duly authorized representative

A “through date” that extends beyond the current pay period is the most common source of unintentional over-release. If the through date on the waiver doesn’t match the through date on your pay application, ask for a corrected form.

Practical Guidance: What to Check Before Signing

Verify the amount. The dollar amount in the waiver must equal the check you are receiving: not the total contract balance, not a rounded figure, not a prior period’s amount. Confirm this before signing.

Check the scope language. Language releasing “all claims” or “all work performed” on what is presented as a progress payment is a red flag. A progress waiver releases rights for that payment only. If the language is broader, it either violates § 22B-5(b) or is being used to disguise a final waiver, both of which you should push back on before signing.

Check the through date. If the waiver covers work through a future date, it may release rights for work not yet complete or not yet paid. Match the through date to your pay application’s period of work.

Conditional or unconditional? For progress payments, prefer conditional waivers. If the requesting party insists on an unconditional form, verify that the amount is limited to the current payment and nothing more. An unconditional waiver covering more than the actual payment amount is unenforceable as to the excess under § 22B-5(b), but that protection exists in statute, not in the language of the document, and litigating about it is not a good outcome.

Final waiver at a progress payment? If the waiver you are being asked to sign releases all lien rights for the project and you are not receiving final payment, it is void under § 22B-5(c). You are not required to sign it.

GC signing on behalf of the project. A general contractor cannot sign a lien waiver or take any other action that prejudices a first-tier subcontractor’s subrogation rights to the real property lien without that subcontractor’s written consent (§ 44A-23(a1)). A GC who signs a broad unconditional waiver that releases lower-tier sub claims without their consent may be personally liable to those subs.

Common Mistakes

• Signing an unconditional progress waiver before payment clears. § 22B-5(b) limits damage for overreaching waivers, but an unconditional waiver scoped precisely to the payment amount is effective the moment you sign it  regardless of whether the check ever arrives. Use conditional waivers for progress payments.
• Not reading the through date. A waiver “through [date]” can cover substantially more work than the pay application you are exchanging it for. Confirm the through date matches your application.
• Accepting a mismatched amount. Even a small discrepancy makes the scope of what you are releasing unclear. Insist on a corrected waiver.
• Treating the “unconditional” label as determinative. It isn’t. § 22B-5 applies regardless of how the waiver is labeled.
• Releasing the GC’s real property lien before lower-tier subs are paid. The GC’s real property lien is the vehicle through which first-, second-, and third-tier subs assert subrogation rights. A GC who releases that lien before lower-tier subs are satisfied without their written consent can face claims under § 44A-23(a1).
• Waiting to sign a release after payment. Once payment has cleared and the project is closed, getting a signed release to the other party quickly avoids title complications and preserves business relationships. A lien that lingers on title after payment is an unnecessary problem for everyone.

Where Lien Waivers Fit in the Larger Process

Lien waivers operate alongside formal lien rights under Chapter 44A. Signing a conditional progress waiver does not release your right to file a claim of lien for unpaid amounts outside the waiver period. Signing nothing does not substitute for the formal steps required to preserve and enforce lien rights.
