Mich. Comp. Laws § 500.405a
If an insurer is subject in its state or country of domicile to formal delinquency proceedings within the meaning of chapter 81 or to a proceeding of similar effect, and the formal delinquency proceeding was properly commenced by the appropriate domiciliary regulatory authority on or after October 1, 1991, the certificates of authority of the insurer and of any current affiliated insurers of the insurer shall be automatically revoked 90 days after the effective date of the delinquency or other proceedings without further action by the commissioner unless, within the 90-day period or a longer period if the commissioner allows, each insurer requalifies for a certificate of authority under the provisions of this act then in force. A domestic insurer for purposes of requalification shall be treated as though it is a foreign insurer. The certificate of authority shall be revoked under such conditions for the protection of the public as the commissioner may require.
