Texas Abandonment of Assumed Name Certificate is a legal document filed with the Texas Secretary of State to end the use of an assumed name. This document is used when a business entity has been using an assumed name but would like to end that use and return to its legal name. There are two types of Texas Abandonment of Assumed Name Certificates: one for unincorporated businesses and one for incorporated businesses. For unincorporated businesses, the certificate must include the assumed name, the date it was used, the owner or owners of the assumed name, and a signed statement of abandonment. For incorporated businesses, the certificate must include the assumed name, the date it was used, the name of the corporation, the state in which the corporation is incorporated, and a signed statement of abandonment. Both types of certificates must be signed by an authorized representative and notarized before being sent to the Secretary of State.
