Mich. Comp. Laws § 168.514
If the registration of an elector is canceled, the clerk shall make a proper entry on the master registration card, indicating the date and the cause for cancellation, and shall affix his or her signature to the entries. All copies of the canceled registration cards must be filed in the office of the clerk. All duplicates of the master registration card canceled may be destroyed 2 years after the registration is canceled. The clerk may also destroy the master registration card of an elector 5 years after the date of cancellation of the elector's registration. The clerk may also destroy any canceled master registration cards 2 years after the date of cancellation if the canceled registration cards are reproduced under the records reproduction act, 1992 PA 116, MCL 24.401 to 24.406, and the reproductions are on file in the office of the clerk. The reproductions may be destroyed after the expiration of the statutory retention date of the reproduced records. A voter registration that has been canceled due to an elector moving out of the jurisdiction must not be reinstated if the elector moves back to the jurisdiction and a new voter registration is required for that elector.
