Connecticut Lien Waiver Forms — Generate in 60 Seconds
Generate Connecticut lien waivers that comply with Section 42-158l of the Construction Contract Act. Connecticut doesn't prescribe mandatory form language, so our custom templates are designed to be clear, enforceable, and aligned with Connecticut's dual-statute framework: Chapter 847 (mechanics liens) and Chapter 742b (construction contract payments). All four waiver types available with free preview. No notarization required.
Which Type Do You Need?
Connecticut uses the standard 4-type framework (conditional/unconditional x progress/final). Key CT rule: Section 42-158l voids any waiver for work not yet "performed and paid for" — both conditions must be met. This makes conditional waivers particularly well-suited to Connecticut projects.

No mandatory statutory form
Connecticut does not prescribe specific waiver form language. Section 42-158l governs when waivers are enforceable, not what they must look like. Form design is up to the parties.
Advance waivers VOID
Section 42-158l: any waiver for services, labor, or materials "not yet performed and paid for" is void. Both performance AND payment must occur first.
Notarization NOT required
Lien waivers don't need notarization in Connecticut. The mechanics lien certificate itself must be subscribed and sworn to (Section 49-34), but that's a separate document.
5% retainage cap (private commercial)
Section 42-158k caps retainage at 5% per progress payment on private projects over $25,000. Owner must deposit retainage in an escrow account.
Subcontractor lien capped at owner's contract price
Section 49-33(e): a sub's lien can't exceed the amount the owner agreed to pay the person through whom the sub claims. Know the contract price above you.
90-day filing deadline
Mechanics lien certificate must be filed with the town clerk within 90 days after last furnishing. Copy to owner within 30 days of filing.
Connecticut Lien Waiver Legal Requirements
Connecticut's lien waiver framework sits across two statutes. The mechanics lien itself is governed by Chapter 847, Section 49-33 et seq. — covering who can lien, filing requirements, and subcontractor rights. Lien waiver enforceability is governed by the Construction Contract Act, Chapter 742b. Section 42-158l is the key provision: it declares void any contract clause or periodic lien waiver that "purports to waive or release the right of a contractor, subcontractor or supplier" to claim a lien "for services, labor or materials which have not yet been performed and paid for." Both conditions — performance and payment — must be satisfied. The Act applies to private projects over $25,000, excluding residential properties of 4 or fewer units. For projects outside this scope, common-law principles govern waiver enforceability. Connecticut also has strong prompt payment protections under Section 42-158j: owners must pay GCs within 30 days of receiving a pay application, and GCs must pay subs within 30 days of receiving payment. Late payments accrue interest at 1% per month.
Recent Law Changes
- No major recent amendments to mechanics lien or lien waiver statutes. The Construction Contract Act (Chapter 742b, Sections 42-158i through 42-158r) remains the primary framework for private commercial project payment and waiver rules.
Connecticut Conditional Progress Waiver
What It Is
Custom template waiving lien rights for a progress payment, conditioned on receipt and clearance of payment. Directly aligned with Section 42-158l's requirement that both performance and payment must occur before a waiver is enforceable.
When to Use
When submitting a pay application or exchanging a waiver for a progress payment you haven't received yet.
Key Legal Points
- No statutory form — our template uses clear, unambiguous language designed for Connecticut compliance.
- Conditional on payment: the waiver takes effect only upon receipt and clearance of the specified payment.
- Section 42-158l reinforces this: waivers are void for work "not yet performed and paid for."
- Retainage excluded — template preserves rights to retained amounts (capped at 5% under Section 42-158k on qualifying projects).
- Change orders and disputed extras preserved as exceptions.
- Covers only the specified payment period — not future work.
Tips
- The conditional structure mirrors Connecticut's own statutory language about performance and payment — it's the natural fit.
- No notarization needed for lien waivers in Connecticut. Keep signed copies for your records.
- Include all key fields: company info, project address, owner, GC, payment amount, and period covered.
Connecticut Unconditional Progress Waiver
What It Is
Immediately waives lien rights for the covered progress payment upon signing. States that payment has been received in full for the covered period.
When to Use
Only after you've received the progress payment and it has cleared your bank. Not just deposited — cleared.
Key Legal Points
- Immediately effective upon signing — no condition precedent.
- Section 42-158l provides a backstop: waivers are void if work hasn't been "performed and paid for." But enforcing this protection means going to court.
- Retainage and disputed extras excluded from the waiver scope.
- Must clearly state the payment amount and identify the property.
- Covers only the specified payment period.
Warning
Once signed, this waiver takes effect immediately. Section 42-158l technically voids waivers without actual payment, but proving it means litigation. Use a conditional waiver if payment hasn't cleared — don't rely on the statute as your safety net.
Tips
- Verify the payment has fully cleared before signing — not just deposited.
- Compare the amount on the waiver to the actual cleared amount. Discrepancies create risk.
- Keep a copy of the cleared check or bank confirmation as evidence of payment.
Connecticut Conditional Final Waiver
What It Is
Waives all remaining lien rights on the project, conditioned on receipt and clearance of final payment including retainage.
When to Use
When requesting final payment (including retainage) and you want your lien rights protected until the money actually clears.
Key Legal Points
- Covers ALL remaining work, services, materials, and equipment on the project.
- Conditional on final payment — including retainage — clearing your bank.
- Section 42-158l aligns: waivers are void unless work has been performed and paid for.
- On qualifying private projects, retainage is capped at 5% (Section 42-158k). Verify the retainage amount matches what's been withheld.
- Owner must release retainage from escrow — confirm escrow account exists per Section 42-158k.
- List any disputed amounts as exceptions to the waiver.
Tips
- Ensure the final payment amount includes all retainage owed. Connecticut's escrow requirement means the money should be readily available.
- If any disputes remain, list them as exceptions rather than signing a clean final waiver.
- Verify the retainage escrow account balance with the owner before signing.
Connecticut Unconditional Final Waiver
What It Is
The most consequential waiver. Immediately and irrevocably releases ALL lien rights on the project upon signing. States that full payment has been received.
When to Use
Only after ALL payment — including final payment and retainage — has been received and fully cleared.
Key Legal Points
- Complete and permanent release of all lien rights on the project.
- Immediately effective — no condition, no recall.
- Must state clearly that full payment for all work, services, materials, and equipment has been received.
- Section 42-158l is your statutory backstop if signed without payment, but enforcing it means litigation.
- No exceptions or carve-outs — this covers everything.
Warning
This is permanent. Once signed and delivered, your lien rights are gone. If any amounts remain outstanding — retainage, change orders, disputed extras — use a conditional final waiver instead. Don't rely on Section 42-158l as a safety net.
Tips
- Verify every dollar has been received and cleared before signing — including retainage from escrow.
- This is the complete release. There's no take-back. Double-check all amounts against your records.
- If open disputes exist, resolve them first or use a conditional final waiver with listed exceptions.
Common Connecticut Lien Waiver Mistakes
- 1
Not knowing the "performed AND paid for" requirement
Section 42-158l requires both conditions — performance and payment — before a waiver is enforceable. A waiver signed after work is done but before payment clears is just as void as one signed before work starts. Both boxes must be checked.
- 2
Signing an unconditional waiver before payment clears
Section 42-158l technically protects you, but enforcing that protection means litigation. Use a conditional waiver when payment hasn't cleared — it's the safer route and mirrors the statute's own "paid for" language.
- 3
Ignoring the 5% retainage escrow requirement
On private commercial projects over $25,000, Section 42-158k caps retainage at 5% and requires it to be held in escrow. If the owner hasn't established an escrow account, that's a red flag. Verify before signing a final waiver.
- 4
Missing the 90-day lien filing deadline
The 90 days runs from when you last furnished labor or materials (Section 49-33). You must also serve a copy on the property owner within 30 days of filing the certificate with the town clerk. Miss either deadline and your lien is invalid.
- 5
Assuming lien waiver rules apply to small residential projects
Chapter 742b (including Section 42-158l) applies only to private projects over $25,000 and excludes residential properties of 4 or fewer units. On excluded projects, common-law principles govern — which means less statutory protection for your waiver rights.
