1. Each retail time contract shall be in writing, shall be signed by both the buyer and the seller, and shall be completed prior to the signing of the contract by the buyer. In addition to such retail time contract, the seller may require the buyer to execute and deliver a negotiable promissory note to evidence the obligation created by the retail time contract, and the seller may require security for the payment of such obligation or the performance of any other condition of the contract, in which case the retail time contract may evidence such security. The fact that a note given to evidence a retail time contract contains the matters and things which sections 408.250 to 408.370 require be included in a retail time contract shall not render such note nonnegotiable under any of the provisions of article 3 of chapter 400 if such note is not otherwise nonnegotiable under said chapter. Any such additional document or documents shall be completed prior to the signing thereof by the buyer. No retail time contract shall require or entail the execution by the buyer of any note or series of notes which, when separately negotiated, will cut off as to third parties any right of action or defense which the buyer may have against the seller.
2. The printed portion of the contract, other than instructions for completion, shall be in at least eight point type. The contract shall contain the following notice in a size equal to at least ten point bold type:
"NOTICE TO THE BUYER:
(1) DO NOT SIGN THIS CONTRACT BEFORE YOU READ IT OR IF IT CONTAINS ANY BLANK SPACES.
(2) YOU ARE ENTITLED TO AN EXACT COPY OF THE CONTRACT YOU SIGN.
(3) UNDER THE LAW YOU HAVE THE RIGHT TO PAY OFF IN ADVANCE THE FULL AMOUNT DUE AND UNDER CERTAIN CIRCUMSTANCES TO OBTAIN A PARTIAL REFUND OF THE TIME CHARGE."
3. The seller shall deliver to the buyer, or mail to him at his address shown on the contract, a copy of the contract signed by the seller. Until the seller does so, a buyer who has not received delivery of the goods or been furnished the services shall have the right to rescind his agreement and to receive a refund of all payments made and return of all goods traded in to the seller on account of or in contemplation of the contract, or if such goods cannot be returned, the value thereof. Any acknowledgment by the buyer of delivery of a copy of the contract shall be in a size equal to at least ten point bold type and, if contained in the contract, shall appear directly above the buyer's signature. The buyer's acknowledgment, conforming to the requirements of this subsection 3, of delivery of a copy of the contract shall be conclusive proof of such delivery, and that the contract when signed did not contain any blank spaces except as provided in subsection 7 or section 408.270 , and of compliance with this section in any action or proceeding by or against a holder of the contract without knowledge to the contrary when he purchases the contract.
4. The contract shall contain the names of the seller and the buyer, the place of business of the seller, the residence of the buyer as specified by the buyer and a brief description of the goods sold or services furnished or to be furnished, and shall clearly state and describe any collateral security taken for the buyer's obligation.
5. The contract shall contain the following items:
(1) The cash sale price of the goods or services;
(2) The amount of the buyer's down payment, and whether made in money or goods, or partly in money and partly in goods, including a brief description of the goods traded in;
(3) The difference between items (1) and (2);
(4) The amount, if any, if a separate charge is made therefor, included for insurance and other benefits, specifying the types of coverage and benefits and the coverage periods and separately stating each amount for each insurance premium or benefit;
(5) The amount of official fees;
(6) The principal balance which is the sum of items (3), (4) and (5);
(7) The amount of the time charge;
(8) The amount of the time balance, which is the sum of items (6) and (7), payable in one or more deferred payments by the buyer to the seller, and the amount of each such payment and the due date or period thereof;
(9) The time sale price.
6. A retail time contract need not be contained in a single document. If the contract is contained in more than one document, then one such document may be an original document applicable to purchases of goods or services to be made by the retail buyer from time to time and in such case such document, together with the sales slip, account book or other written statement relating to each purchase, shall set forth all of the information required by this section and shall constitute the retail time contract for each such purchase.
7. No retail time contract shall be signed by any party thereto when it contains blank spaces to be filled in after it has been signed except that, if delivery of the goods is not made at the time of the execution of the contract, the identifying numbers or marks of the goods or similar information and the due dates of the payments may be inserted in the contract after its execution.
8. Upon written request from the buyer the holder of a retail time contract shall give or forward to the buyer a written statement of the dates and amounts of payments received and charges imposed and the total amount unpaid under such contract. A buyer shall be given a written receipt for any payments when made in cash.
9. No provision in a retail time contract relieving the seller from liability for any legal remedies which the buyer may have against the seller under the contract or any separate instrument executed in connection therewith shall be enforceable.
10. After payment of all sums for which the buyer is obligated under a contract and upon written demand made by the buyer the holder shall deliver or mail to the buyer at his last known address one or more good and sufficient instruments to acknowledge payment in full and shall release all security in the goods or in any collateral security.
11. No retail time contract shall contain any provision by which the buyer agrees to relieve the seller, assignee or holder of any liabilities, or whereby the buyer agrees to waive any claim, rights or legal remedies which the buyer may have against the seller, assignee or holder under the retail time contract.
