Recording and enforcing a New Jersey lien

Recording the lien

Record with the county clerk where the property sits. Whether electronic recording is accepted varies by county, so confirm with the recording office and build mailing time into the deadline. The lien must be notarized. The lien claim must be sworn to under oath.

After recording

A copy of the recorded lien must be served on the property owner and the general contractor within 10 days of recording. To keep the lien alive it must be enforced by lawsuit within 1 year after last furnishing labor or materials.

Wrongful lien exposure

New Jersey exposes claimants who file an exaggerated or baseless lien to damages. If a lien claim is without basis (frivolous, false, unsupported by a contract, or made in bad faith), willfully overstated, or not lodged in the required form, manner or time, the claimant forfeits the lien rights for the face amount and must pay the owner's or contractor's court costs and attorney's fees, and the court enters judgment for damages to anyone adversely affected.

Practitioner notes for New Jersey

New Jersey's Construction Lien Law (N.J.S.A. 2A:44A-1 et seq.) sets different tracks for commercial and residential work. On a commercial project there is no required preliminary notice; the lien claim must be lodged for record with the county clerk within 90 days after the last date work, services, material or equipment were provided (2A:44A-6). On a residential project, the claimant must first lodge a Notice of Unpaid Balance and Right to File Lien with the county clerk within 60 days after last furnishing, and serve a demand for arbitration within 10 days after that (2A:44A-21). The arbitrator rules on whether a lien may be filed and for how much. The lien claim itself is then due within 10 days after the claimant receives that decision, and never later than 120 days after last furnishing (2A:44A-6, 2A:44A-21). Every lien claim must be signed, acknowledged and verified by oath. Suit to enforce must be filed within 1 year after the last work or materials, or within 30 days after receiving a written demand to sue, whichever comes first (2A:44A-14). Be precise about the amount. A claim that is without basis or "willfully overstated", or that is filed late or in the wrong form, is forfeited, and the claimant must pay the other side's court costs and attorney's fees, plus damages (2A:44A-15). The residential steps have short, linked deadlines, so confirm with counsel early.
