New Jersey Statutes Title 46. Property .46 § 23-11

Whenever there has been or may be duly filed in the office of the county recording officer in any county maps of lands, and there have been made duplicate copies thereof, which copies have been delineated identically with the maps so filed, except for the style or title thereof, and such duplicate maps have not been filed in the office of such county recording officer, and there have been made conveyances of lands, or interests therein, and other instruments of similar nature, under which the lands intended to be conveyed or liened, have been described by reference to such unfiled map, the governing body of any municipality within this state and located in any such county may provide for the filing of a duplicate of such map delineated identically with the filed map, even though the title or style of the map may be in different form from the filed map approved by such municipality in the manner prescribed by law; but any such approval and filing shall not constitute a dedication of the streets or lot locations as therein delineated; and any such approval and filing of any such map shall be merely for the identification of the lands theretofore conveyed or liened, which approval shall be stated in the resolution adopted by the governing body approving such maps.
