The case search application will not display whether or not a case is in warrant status (i.e., an arrest warrant has been issued). If you think your case may be in warrant status, you should contact the court at (989) 731-0201, Monday-Friday, 8:00 a.m. to 4:30 p.m.
The case search application will not display information on non-public cases. There are categories of cases where information about the defendant and case is not available to the public. You cannot ask for information about a non-public case over the telephone or through the mail. Court personnel cannot acknowledge that a non-public case exists except to authorized persons who appear in person at the courthouse.
