The Texas Dental Support Organization Ownership Information Addendum is a document that is used to provide information about the ownership of Dental Support Organizations (DSO's) in the state of Texas. It is required by the Texas State Board of Dental Examiners and must be filled out and submitted with the DSO application. The document includes information such as the names and addresses of all owners, the percentage of ownership interest of each owner, and any financial arrangements between the owners and the DSO. There are two types of Texas Dental Support Organization Ownership Information Addendum: the Initial Ownership Information Addendum and the Change of Ownership Information Addendum. The Initial Ownership Information Addendum is required for all new DSO applications and must be filled out in its entirety. The Change of Ownership Information Addendum is required for any subsequent changes in ownership or financial arrangements between the owners and the DSO.
