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.
