New Jersey Statutes Title 46. Property 46 § 26B-8

Whenever a map has been filed in the office of the county recording officer, and copies of it have been made that differ from the original only in title or style, and there have been made conveyances or liens, under which the lands intended to be conveyed or liened have been described by reference to the unfiled copy, the governing body of the municipality in which the land is located, by resolution, may approve the copy for filing in the manner prescribed by law. This approval and filing shall not constitute a dedication of the streets or lot locations as therein delineated and shall be merely for the identification of the lands conveyed or liened.
