Kan. Admin. Regs. § 75-6-1
The parties to a sale, lease, loan, or modification of a sale, lease, or loan that is not a consumer credit transaction may agree in a writing signed by the parties to make the transaction subject to the Kansas uniform consumer credit code. Any such agreement may be included in the contractual agreement evidencing the credit transaction, and when so included, no additional signatures shall be required to evidence the agreement to include the transaction within the scope of the Kansas uniform consumer credit code other than the signatures normally used in executing the credit transaction. In order to be effective, each such agreement shall be executed simultaneously with the contractual agreement evidencing the credit transaction.
