DBA “Doing Business As” or Co-Partnerships

The “Certificate of Assumed Name” and “Certificate of Co-Partnership” are legal documents.Information given on these forms should be as complete and accurate as possible.

Step 1: Check the name

The first step is to confirm that the business name you have selected is acceptable. The Clerk is authorized to reject any assumed name, which is likely to mislead the public, or is similar to other business names as to lead to confusion or deception. The registering of the name places that name on public record indicating that the registrant(s) is/are conducting business under an assumed name. A DBA protects a business from possible name duplications by other businesses.

Step 2: Check with the State

This ensures that the business name is not being used by a corporation, limited liability company (“LLC”), limited liability partnership (“LLP”), or non-profit organization, which are only filed at the state level, State of Michigan Business Entity Search. It is your responsibility to check at the state level, local telephone books, online and news media to make certain there is no existing business using the name you have chosen. You can also contact the Corporation Bureau in Lansing at: 517-241-6470.

Step 3: Complete & file the DBA / Co-Partnership form
