Notice to the Buyer
A copy of any such account executed on or after January 1, 1960, shall be delivered or mailed to the retail buyer by the retail seller prior to the date on which the first payment is due thereunder. Any acknowledgment by the buyer of delivery of a copy of the account shall be in a size equal to at least 6-point type and, if contained in the account, shall appear directly above or adjacent to the buyer's signature. No account executed on or after January 1, 1960, shall be signed by the buyer when it contains blank spaces to be filled in after it has been signed. The buyer's acknowledgment, conforming to the requirements of this subsection, of delivery of a copy of an account shall be presumptive proof, in any action or proceeding, of such delivery and that the account, when signed, did not contain any blank spaces as herein provided. Every account executed on or after January 1, 1960, shall state the amount of, or the method of calculating, the finance charge to be charged and paid pursuant thereto or shall state that a finance charge not in excess of that permitted by this law will be charged and paid pursuant to such account. A revolving account agreement is considered to be signed or accepted by the buyer if, after a request for a revolving account, the agreement or application for a revolving account is in fact signed by the buyer, or if that revolving account is used by the buyer or by another person authorized by the buyer to use it. The seller bears the burden of proving authorized use.
The items need not be stated in the sequence or order set forth in this paragraph, and additional items may be included to explain the computations made in determining the amount to be paid by the retail buyer.
