New Jersey Mechanics Lien Law: Deadlines, Notices & Filing Guide
New Jersey mechanics lien and bond claim deadlines under N.J. Stat. § 2A:44A-6 (private) and § 2A:44-145 (public), from My Lien Lawyer. Lien rights are limited to first- and second-tier claimants, with a 90-day filing window and 1-year suit deadline.
New Jersey mechanics lien deadlines at a glance
New Jersey does not use a traditional preliminary notice system; instead, lien eligibility itself is limited to first-tier subcontractors and suppliers and second-tier suppliers to first-tier subcontractors. Claimants further removed from the owner or general contractor in the contracting chain simply have no lien rights to protect, regardless of any notice they might serve.
The lien claim must be lodged for record within 90 days of the date the claimant last provided work, services, material, or equipment to a non-residential project, under N.J. Stat. § 2A:44A-6.
Suit to enforce the lien must be commenced within 1 year after last furnishing labor or materials, under N.J. Stat. § 2A:44A-14; missing this deadline extinguishes the lien.
A claimant on a New Jersey public bond must serve written notice of the bond claim on the prime contractor and surety within 90 days of last furnishing labor or materials, and suit on the bond may not be commenced more than 1 year after last furnishing.
Primary statute

Who can file a mechanics lien in New Jersey?
New Jersey construction lien rights extend only to first-tier subcontractors and suppliers, and to second-tier suppliers who supply first-tier subcontractors; more remote claimants and general contractors covered elsewhere in the statute may also qualify depending on their contractual position.
Overview of New Jersey lien practice
New Jersey narrows the pool of eligible lien claimants more than most states, extending rights only to first-tier subcontractors and suppliers and to second-tier suppliers who supply those first-tier subcontractors, which means remote sub-subcontractors or suppliers further down the chain have no lien remedy at all under this statute. For those who do qualify, the lien claim must be lodged for record within 90 days of last providing work, services, material, or equipment, and a copy must be served on both the owner and contractor within 10 business days of filing. Because the 1-year suit deadline runs from last furnishing rather than from the recording date, claimants should not assume they have a full year after recording to act; filing the bond claim notice or lien well ahead of that deadline is the safer practice. Filing a Notice of Unpaid Balance before recording the lien can preserve priority back to the date of that filing, which matters when multiple claimants compete for limited funds. Recording must occur in the correct county and identify the actual owner of record. Public project claimants follow a parallel 90-day bond notice and 1-year suit deadline under a separate statute. Federal property remains outside this framework.
Common pitfalls on New Jersey projects
Recorded lien must be served promptly
A copy of the recorded lien claim must be served on the owner and contractor within 10 business days of filing to remain enforceable.
NUB filing can preserve priority
Filing a Notice of Unpaid Balance before the lien preserves priority back to the date the NUB was filed, which can matter when funds are limited.
Missed suit deadline extinguishes the lien
Failure to commence suit within 1 year of last furnishing extinguishes the lien entirely, regardless of when it was recorded.
Bond claim notice needs certified mail
Notice of a public bond claim must be served on the prime contractor and surety, and doing so by certified mail helps establish proof of timely service.
