Mich. Comp. Laws § 322.551

Sec. 1. Any person or the heirs, executors, administrators or assigns of any person who has made a good faith purchase of land from the state of Michigan and received from the state a conveyance purporting to pass absolute title to said land, shall be entitled to a second conveyance by the state if it shall be found that, at the time of the original conveyance, title to the land was vested in the United States and that the title has been subsequently acquired by the state from the United States. The director of conservation is hereby authorized to issue a quit claim deed in such case to any person entitled thereto, providing said person shall submit to the attorney general evidence of his ownership in said land, and that the attorney general shall certify to the director of conservation that said person is entitled to have a good and sufficient title to said land, based upon the original conveyance from the state.
