Denton County Clerk

The Denton County Clerk administers the assumed name process in Collin County. Part of far north Dallas is in Denton County. Sole proprietorships and general partnerships must file an assumed name certificate in the county where they do business.


Assumed Name Certificates (DBA or “Doing Business As”)

While information regarding Assumed Name searches is available via the internet at:, the information available online may not be as current as the information available in the office. Conducting the search online and mailing the filing request with fees could result in another business retaining the same Assumed Name. Currently the only method to ensure a thorough search of an Assumed Name is to personally appear in the County Clerk’s Office to conduct the search.

Currently, you may request that a search be performed on the name that you are interested in by mail for a fee of $10.00. However, if you come to our office in person, there is no fee for the search and friendly clerks are available to assist you in your business name search. Once the search is completed, the application can be signed in front of one of our clerks (must have a valid driver’s license) instead of a notary and your application will be processed immediately. Assumed name searches and assumed name recordings can be done through all County Clerk satellite locations.


The fee for an Assumed Name Certificate to be filed and recorded is $24.00 if it is already notarized and $25.00 if the clerk must witness a signature. There is an additional $0.50 for each additional signature on the business name (i.e. A sole proprietor pays $24.00 for an assumed name certificate, and a partnership with two signers on the business name pays $24.50. In both cases, the form has been already notarized). The same fees apply for Abandonment of Assumed Name filings. Accepted payment options are: cash, money order, cashier’s check, personal check or business check. We do accept some credit and debit cards. Certain rules, restrictions and fees apply to credit card use. Please call our office at 940-349-2010 for details if paying by credit card.
