New Jersey Mechanics Lien Statutes: Deadlines, Venues & Citations
Where New Jersey liens are filed and enforced
A New Jersey mechanics lien is filed with the County Clerk in the county where the project sits — 90 days from last date of furnishing. Filing in the wrong county does not perfect the claim, which matters on projects that straddle county lines. Those are two different clocks against two different offices, and New Jersey claimants lose rights far more often by missing the second one than the first.
New Jersey deadlines by claimant role
For subcontractors and suppliers: Preliminary notice — 60 days from first furnishing (N.J.S.A. § 2A:44A-20); Record the lien — 90 days from last furnishing (N.J.S.A. § 2A:44A-6); file suit — 1 years from lien recorded (N.J.S.A. § 2A:44A-14); bond notice — 275 days from last furnishing (N.J.S.A. § 2A:44-145); file suit — 1 years from last furnishing (N.J.S.A. § 2A:44-145); Pre-lien notice — 20 days from first furnishing (N.J.S.A. § 2A:44-128). For general contractors: Record the lien — 90 days from last furnishing (N.J.S.A. § 2A:44A-6). Every window runs from the claimant's own dates, not the unpaid invoice date.
Rules specific to New Jersey
REQUIRED: File 'Notice of Unpaid Balance and Right to File Lien Claim' with county clerk and serve on owner. Required before filing lien. Time limit varies. File lien claim with county clerk within 90 days of last furnishing of labor or materials. File lien claim within 90 days. Must have filed notice of unpaid balance first. File suit to enforce lien within 1 year of recording. The statute's literal notice window is ONE YEAR from the beneficiary's last actual work or delivery, but it is unusable at the end: no action may be brought until the EXPIRATION OF 90 DAYS after the statement of the amount due is provided to the sureties AND the contractor, and no action may be brought later than ONE YEAR from that same last date. The 90-day wait must therefore finish inside the same year, making ~DAY 275 the last workable service date. Recipient is the SURETIES, not the prime alone — the prior 'Prime Contractor and Surety / 90 days / 2A:44-143' row was wrong on the deadline, the trigger arithmetic and the citation. Missing the notice is NOT total forfeiture: the beneficiary has rights only to the benefits available FROM THE DATE THE NOTICE IS PROVIDED. Suit against the sureties is barred later than 1 year from the last date the beneficiary performed actual work or delivered materials, AND may not be brought until 90 days after the statement of the amount due was provided to the sureties and the contractor. Both ends bind: the earliest filing date is statement + 90 days, the latest is last furnishing + 1 year. MUNICIPAL MECHANICS LIEN track, separate from and cumulative to the bond. New Jersey DOES have a public-work lien: it attaches to the CONTRACT FUNDS the agency still holds, not the public property. A person furnishing labor or materials TO A SUBCONTRACTOR must file this written notice within 20 days of the FIRST performance of work or delivery to that subcontractor — the earliest deadline on a NJ public job. Failure bars the lien for those labor or materials UNLESS money is owing from the contractor to that subcontractor, in which case the lien is limited to no more than that amount; a late notice still secures work performed after the filing date. MUNICIPAL MECHANICS LIEN claim. A lien claimant may file a NOTICE OF LIEN CLAIM VERIFIED BY OATH at any time BEFORE the whole work to be performed by the contractor is completed or ACCEPTED BY RESOLUTION of the public agency, or WITHIN 60 DAYS THEREAFTER. Acceptance by resolution is a public act traceable through agency minutes. The lien only has value while the agency still holds contract funds, so it decays as the job pays out — the inverse of the bond claim, which survives a fully paid-out job.

Public projects in New Jersey
No lien attaches to public property in New Jersey. On public state local and public federal work the remedy is a payment bond claim instead — bond notice within 275 days of last furnishing, served on the SURETIES on the bond — and serve the contractor the same day, because the 90-day waiting period runs from provision to the sureties AND the contractor (N.J.S.A. § 2A:44-145). 7 public-project deadlines are tracked for New Jersey.
