Orange County keeps DBA work with the County Clerk. Filing, amending, or discontinuing a Business Certificate, also called a DBA certificate, is done at the County Clerk’s office. Forms can be downloaded or completed in person when filing. The county’s DBA packet adds the practical details.
Forms must be completed, signed, and notarized when presented. The individual or sole proprietor business certificate also has a filing fee.
Choose the original, amendment, or discontinuance form, notarize signatures, and confirm the current fee before going to the clerk.
Keep the exact business name, matching form, notarized signatures, fee confirmation, and filed certificate together. Use the same County Clerk route when the DBA needs an amendment or discontinuance.
