Michigan Compiled Laws, Chapter 487. Financial Institutions § 487.2157

Sec. 37. (1) A drawer may rescind a deferred presentment service agreement without cost to the drawer and for any reason if the drawer, not later than the close of business on the business day following the date of the deferred presentment service transaction, either delivers to the licensee cash in an amount equal to the amount the drawer received if the drawer received cash in the transaction or returns to the licensee the licensee's check the drawer received if the drawer received a check from the licensee in the transaction. The licensee shall return to the drawer the check received in the transaction and any service fee paid by the drawer to the licensee. A drawer who rescinds an agreement under this section is not eligible for restitution under section 36  1 with regard to the rescinded agreement.

(2) A drawer may redeem a check from the licensee holding the check in a deferred presentment service transaction at any time before the maturity date. A licensee shall return the check to the drawer upon receipt of cash or its equivalent in the full amount of the check. A licensee shall not contract for or collect a charge for accepting partial payments from the customer if the full amount is paid by the maturity date.
