40-14-312. Delinquency charges.
(a) With respect to a consumer loan, refinancing, or consolidation, the parties may contract for a delinquency charge on any installment not paid in full within ten (10) days after its scheduled due date in an amount not exceeding the greater of:
(i) Five percent (5%) of the unpaid amount of the installment; or
(ii) Ten dollars ($10.00).
(b) A delinquency charge under paragraph (a)(i) of this section may be collected only once on an installment however long it remains in default. No delinquency charge may be collected if the installment has been deferred and a deferral charge (W.S. 40-14-313) has been paid or incurred until ten (10) days after the deferred due date. A delinquency charge may be collected at the time it accrues or at any time thereafter.
(c) No delinquency charge may be collected on an installment which is paid in full within ten (10) days after its scheduled installment due date even though an earlier maturing installment or a delinquency charge on an earlier installment may not have been paid in full. For purposes of this subsection payments are applied first to current installments and then to delinquent installments.
(d) If two (2) installments or parts thereof of a precomputed loan are in default for ten (10) days or more, the lender may elect to convert the loan from a precomputed loan to one in which the loan finance charge is based on unpaid balances. In this event he shall make a rebate pursuant to the provisions on rebate upon prepayment (W.S. 40-14-319) as of the maturity date of the first delinquent installment, and thereafter may make a loan finance charge as authorized by the provisions on loan finance charge for consumer loans (W.S. 40-14-310) or the provisions on loan finance charge for supervised loans (W.S. 40-14-348), whichever is appropriate. The amount of the rebate shall not be reduced by the amount of any permitted minimum charge (W.S. 40-14-319). If the lender proceeds under this subsection, any delinquency or deferral charges made with respect to installments due at or after the maturity date of the first delinquent installment shall be rebated, and no further delinquency or deferral charges shall be made.
