Filing Process

At the time of filing, this office will verify if the business name chosen is available in this county. It is your responsibility to check at the state level, local telephone books, and news media to make certain there is no existing business using the name you have chosen. 

Once accepted, certified copies of that business name will be issued. The Certificate of Assumed Name and Certificate of Co-Partnership are not complicated, yet they are legal documents. Information given on them should be as complete and accurate as possible.


The fee for filing or renewing either the Certificate of Assumed Name or the Certificate of Co-Partnership is $10. The certificate is valid for five years from the date of filing.


Notarization of the certificate is necessary. If more than one person owns the business, all need to be present when filing, if the certificate is notarized by this office (otherwise, your signature must be notarized by an outside notary prior to filing in this office).

  • The business is dissolved
