1. (a) The parties to a covered transaction may contract for a late fee on any installment not paid in full within 10 calendar days after its scheduled or deferred due date in an amount not to exceed 5% of the unpaid amount of the installment or $25, whichever is less.
2. (b) As an alternative to the late fee set forth in subsection (a), the parties to a covered transaction may contract for a late fee not to exceed $10 on any installment not paid in full within 10 calendar days after its scheduled or deferred due date, except that if the scheduled payment amount is $25 or less, the maximum late fee shall be $5.
3. (c) A late fee may be assessed only once on an installment regardless of the length of time such installment remains in default. A late fee may be collected at the time it is assessed or at any time thereafter.
4. (d) No late fee may be assessed when such a fee or charge is attributable solely to the failure of the consumer to pay a late fee on an earlier installment and the payment is otherwise a periodic payment received on the due date or within 10 calendar days after its scheduled or deferred installment due date.
5. (e) This section shall be a part of and supplemental to the Kansas mortgage business act.
