New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 61-16

Any purchaser of real estate at any public sale, held by any officer or person mentioned in section 2A:61-1 of this title, except at sales under general execution and actual levy thereunder, or for unpaid taxes or municipal liens, shall be entitled to be relieved from his bid if, before delivery of the deed, he shall satisfy the court by whose authority such sale was made of the existence of any substantial defect in or cloud upon the title of the real estate sold, which would render such title unmarketable, or of the existence of any lien or encumbrance thereon, unless a reasonable description of the estate or interest to be sold, and of the defects in title and liens or encumbrances thereon, with the approximate amount of such liens and encumbrances, if any, be inserted in the notices and advertisements required by law, and in the conditions of sale; but, if the court shall direct any lien or encumbrance not described, and which is due and payable, to be paid out of the proceeds of sale, the purchaser shall not then be relieved by reason of such lien or encumbrance.
