Mich. Comp. Laws § 333.1222: Renewals; distribution of work; pro rata fee; waiver.

Sec. 1222.

In order to distribute the work of renewals in the interests of administrative efficiency, the appropriate state agency may:

Schedule expirations established under section 16194 or otherwise under law to spread them over each year of a biennium or longer term.

Issue initial licenses in the interim during a normal term to expire on the next normal expiration date or the first normal expiration date thereafter, and prorate the fees therefor.

The issuing agency shall collect, before a renewal is issued under section 1221 or this section, a pro rata fee for the period of the extension granted under section 1221 or this section. However, to save administrative costs, the agency may waive this fee for an extension of not more than 2 months.
