General information [back to top]  
Agency:
County Clerk's Office (COUNTY)
Description:
A sole proprietorship is a type of business entity that legally has no separate existence from its owner. There is only one owner, and this person does business in his or her own name.

A sole proprietor must register to operate under a name other than his or her own name. To do so, sole proprietors must file a Certificate of Assumed Name, sometimes also called a “Doing Business As” Certificate, with the County Clerk in each county where he or she plans to do business. These filings can be made by business owners directly to the County Clerk's offices in the county or counties in which the business will operate. However, it is highly recommended that business owners consult an attorney, and in some cases an accountant, to learn about the full implications of various legal structures and related partnership agreements with regards to financial and legal liability, taxation, and planning for the possibility of sale or dissolution.

Please see the Additional Information links below for a summary of the laws pertaining to sole proprietorships, and the steps required to file and process the documents needed to operate your business under your “Doing Business As” name. For information about filing in a specific county, please contact the appropriate County Clerk's Office using the contact information available below.
