First, there are three ways to ensure the business name you want to file under is available and there are no trademark issues:
After obtaining a copy of the ‘doing business as’ in Illinois application form, if you don’t have legal counsel or a DBA filing service, take your time and make sure each entry is correct.
Read all instructions before you start answering as well. Specific information about your Illinois DBA business needs to be provided.
The final step is to mail the finished Illinois DBA application form after being notarized along with your application fee.
The mailing address will be provided by the county clerk and on the form itself. As soon as you have mailed it, all you need to do now is publish the assumed name in the local newspaper for 3 consecutive weeks which the clerk can help with as well.
Note that this guide is not legal advice. If you’re looking for expert advice on Illinois DBA registration or starting a business in Illinois, please schedule an appointment with a lawyer.
