Section 6

Every assurance company to whom notice was duly given of the assignment of any policy under which the company is liable shall, upon the request in writing of any person by whom any such notice was given or signed, or of his executors or administrators, deliver an acknowledgment in writing under the hand of the manager, secretary, treasurer, or other principal officer of the assurance company, of its receipt of such notice; and every such written acknowledgment, if signed by a person being de jure or de facto the manager, secretary, treasurer, or other principal officer of the assurance company whose acknowledgment the same purports to be, shall be conclusive evidence as against such company of it having duly received the notice to which such acknowledgment relates.
