KRS 371.230: Contracts composed of more than one document.

A retail installment contract need not be contained in a single document. If the contract is

contained in more than one (1) document, one (1) such document shall be an original

document signed by the retail buyer, stated to be applicable to purchases of go ods or

services to be made by the retail buyer from time to time. 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 KRS 371.220 to 371.290 and

shall constitute the retail installment contract for each purchase. On each succeeding

purchase pursuant to such original document, the sales slip, account book or other written

statement may at the option of the seller constitute the memorand um required by KRS

371.290.
