N.J. Stat. Ann. § 13:8B-4

No conservation restriction or an historic preservation restriction held by the State or a local unit or by a charitable conservancy, shall be unenforceable by reason of lack of privity of estate or contract, or lack of benefit to particular land, or an account of the benefit being assignable or being assigned to any other governmental body or charitable conservancy with like purposes. All such restrictions shall be duly recorded and indexed in the registry of deeds for the county where the land lies so as to affect its title, in the manner of other conveyances of interests in land, and shall describe the land subject to said restrictions by adequate legal description or by reference to a recorded plan showing its boundaries.
