Search and Apply for Assumed Names/Co-Partnerships

Business name searches and registrations for Assumed Names and Co-Partnerships are available through the Oakland County Clerk's Office. 

  • An Assumed Name consists of one or more parties.  It is more binding since all parties listed must sign the documents in front of a notary public and no changes can be made without the signatures of all parties involved.
  • A Co-Partnership consists of two or more parties and may be dissolved or changed by the signature of any party.

The Oakland County Clerk's Office is required to ensure that the business name you are seeking is not being used as an Assumed Name or Co-Partnership within Oakland County. You may apply in person at the Vital Records office or by mail.
