N.J. Stat. § 45:22-33
No pawnbroker, his agent or attorney, shall receive, by way of pledge or pawn, from any person any mechanic's tools used in the erection, addition or alteration of any building or structure, unless said person produces before said pawnbroker, his agent or attorney, two reputable citizens who reside in the county in which the pawnbroker is doing business, and who shall respectively subscribe to an affidavit containing the name, residence and occupation of such affiant, and setting forth that said affiant verily believes that the person desiring to pledge said mechanic's tools is the true owner thereof. Every such affidavit shall be kept on file by the pawnbroker and a note thereof made in his book and shall be subject to the same inspection as his books, and the pawnbroker shall furnish without charge a true copy of said affidavit to each person making the same. A pawnbroker who violates any of the provisions of this section shall be guilty of a misdemeanor.
