DBA

ALL Assumed Name and Co-Partnership forms must be notarized in front of a Notary.  All of our office staff are notaries to help with this service and require a valid Driver’s License or State ID to process. 

The Certificate of Assumed Name and Certificate of Co-Partnership are legal documents.  They should be filed in all counties in which business is conducted.  Information given on these forms should be as complete and accurate as possible.

It is your responsibility to check local resources to verify that no existing business is using the same name or a name confusingly similar to the name you have chosen.  Names used at the County level are not exempt from use at the State level and vice versa.

It is your responsibility to notify this office and file the required forms if you:

  • Change the principal business address
  • Add or delete listed owners
  • Dissolve the business

Listed below are some the agencies that handle other requirements and regulations which may affect your business.  Please contact them directly for any information regarding your business.

Corporations, LLC’s, Non-Profit organizations and LLP’s DO NOT file with this office.

Contact the Corporation Division of the Michigan Dept. of Licensing & Regulatory Affairs (see contact information below).
