Michigan: Local History & Genealogy Resource Guide

Courthouse Records

County level research is essential in the pursuit of family and local history. The list below highlights the most common county courthouse records used by genealogists, but there are many more record sets available. Use the guides below and explore the specific resources for the counties of interest to assure that you locate all pertinent documents.

When requesting courthouse records, inquire about both docket books and paper files. Often both types of material exist for each record. While the two formats may merely repeat the data, one may be easier to read than the other. And, in many cases, there are further details, unique notations, over-sized pages such as maps, and so on, that are filed in only the docket book or in only the paper file. Seeing both will provide a more complete review of the record.
