All persons listed on the DBA/Co-Partnership form must provide their full names and addresses. DBA/Co-Partnership/Dissolution forms may be submitted in person or by mail. If you decide to file in person, all persons listed as owners must be present at the time of filing and must present a state issued picture ID (drivers license or ID card). All signatures must be notarized if the forms are going to be submitted by mail.
The fee to file a DBA/Co-Partnership/Dissolution form is $10.00. We do not charge to change the address of a business; however, if there are multiple owners, all must be present to sign the form with the new address.
The fee for additional certified copies of any business filing is $2.00 per copy.
We accept cash (in office only), check, money order, MasterCard and Visa as form of payment. Please make checks payable to the Ingham County Clerk.
