Connecticut lien waiver requirements

Connecticut is a non-statutory state

Connecticut does not prescribe a statutory lien-waiver form or mandatory waiver language — waivers are governed by general contract principles and may be freely worded, so long as they clearly identify the amount waived and the property. By statute (Conn. Gen. Stat. § 42-158l), any contract provision waiving or releasing mechanic's-lien rights for work not yet performed and paid for is void as against public policy; lien rights may only be waived after the work is done and payment is received.

Statute: Conn. Gen. Stat. § 42-158l (anti-advance-waiver); mechanic's lien framework at Conn. Gen. Stat. §§ 49-33 to 49-39

Requirements at a glance

Notarization: Notarization is not required for a Connecticut lien waiver to be effective and is generally discouraged, as it provides no added enforceability benefit.
Mandatory statutory language: No statutorily required waiver language. A waiver is valid if in writing, signed by the waiving party, and clearly stating the amount waived and the property it applies to. Note: a contractual provision waiving lien rights for work not yet performed and paid for is void under Conn. Gen. Stat. § 42-158l.
Electronic signatures accepted

Mechanics lien filing deadline: Within 90 days after last furnishing labor or materials; the lien certificate is recorded with the town clerk and must be served on the owner within 30 days of recording (Conn. Gen. Stat. § 49-34).

Do lien waivers need to be notarized in Connecticut?

No. Connecticut lien waivers do not need to be notarized to be effective, and notarization is generally discouraged because it adds no enforceability benefit.
