New Jersey Statutes Title 47. Public Records 47 § 1-9

The clerks, registers of deeds and mortgages and surrogates of the several counties of this state may, whenever any of the maps on file in their respective offices shall, by public use, become so worn, torn or otherwise impaired as to be wholly or partly illegible, employ a competent person to copy, retrace, redraft or otherwise restore or make legible such maps, and reindex the same. The compensation of the person so employed shall be fixed and paid by the boards of chosen freeholders of the several counties, according to law.
