Inventory forms and printed copies of the law prepared as provided in subdivision 3411(6) of this title, shall be delivered by the town clerk or listers to all taxpayers requesting the same. At the expense of the town, listers shall forward by mail such inventories and copies to such foreign corporations and nonresidents who are taxable therein, except those taxable for real estate only, as shall be known to them; and the listers or town clerk in like manner may furnish such copies to any taxpayer. Failure on the part of the listers or town clerk to mail or otherwise to furnish such copies, or of the aforesaid persons or corporations to receive the same, shall not in any manner affect or invalidate a grand list prepared and filed according to law. (Amended 1993, No. 49, § 3, eff. May 28, 1993.)
