Recording and enforcing a New Jersey lien
Recording the lien
Record with the county recorder where the property sits. Electronic recording is not generally available, so 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 has no dedicated wrongful-lien penalty statute, but an inflated or baseless lien can still be challenged and removed at the claimant's expense.
