N.J. Stat. § 40A:12-13.3
Notwithstanding any provisions of law to the contrary, when any governing body of a county determines that all or any part of a tract of land, with or without improvements, owned by the county is not then needed for county purposes, it may, by resolution or ordinance, as appropriate, authorize a private sale and conveyance of the same, or any part thereof, to a municipality in the county without compliance with any other law governing disposal of lands by counties, for a consideration which may be nominal, and containing a limitation that such lands or buildings shall be used only for public purposes of such municipality, and that if said lands or buildings are not used in accordance with said limitation, title thereto shall revert to the county without any entry or reentry made thereon on behalf of such county.
