We have the applications for Assumed Names (DBA) in the County Clerk's Office. At the time of filing we check the name of the business to make sure no one else is using that name in Montcalm County. The cost for filing is $10 and the filing is valid for a period of five years. Assumed name applications (DBA), MUST be signed in front of a Notary Public. We have one available in our office daily, Monday-Friday 8am-4pm.
