DBA - Doing Business As

Registering a Business name in Ingham County protects the business name in Ingham County only.

The certificate expires after five (5) years.

If a DBA/Co-Partnership is not renewed, the name becomes available for someone else's use. 

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 a DBA 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). If you decide to file a Co-Partnership in person, at least one person listed as owners must be present to sign and certify all other signatures 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.
