Mich. Comp. Laws § 500.1510: Insurance premium finance agreement; delinquency charge; cancellation charge.

Sec. 1510.

An insurance premium finance agreement may provide for the payment by the insured of a delinquency charge of $1.00 to a maximum of 5% of the amount of the delinquent installment payment on any installment payment that is in default for a period of 10 days or more. However, an insurance premium finance agreement shall not provide for the payment by the insured of a delinquency charge that exceeds $5.00 on any installment that is in default for a period of 10 days or more for either of the following:

An insurance premium finance agreement that finances an insurance contract primarily for a personal, family, or household purpose.

An insurance premium finance agreement, the annual premium of which does not exceed $10,000.00, that is issued to a nonprofit organization exempt from taxation under section 501 of the internal revenue code of 1986, 26 U.S.C. 501.

If a default under subsection (1) results in the cancellation of any insurance contract listed in the agreement, the agreement may provide for the payment by the insured of a cancellation charge equal to the difference between any delinquency charge imposed in respect to the installment in default and $5.00.
