Premiums and refunds

(1) Each policy, certificate, or statement of insurance shall provide that in the event of termination of the insurance prior to the scheduled maturity date of the indebtedness, any refund of an amount paid by the debtor for insurance shall be paid or credited promptly to the person entitled to it. The formula used in computing the refund shall be filed with and approved by the commissioner under Chapter 21, Part 2, Approval of Forms. No refund is required if it would be less than $5. (2) If a creditor requires a debtor to make any payment for credit life or credit accident and health insurance and an individual policy, certificate, or statement of insurance is not issued, the creditor shall immediately give written notice to the debtor and credit the account. (3) The amount charged the debtor for credit life or accident and health insurance may not exceed the premiums charged by the insurer as computed at the time the charge to the debtor is determined.
