Each risk manager must at all times keep the Texas Department of Insurance informed of the risk manager's address. Such address must be included in each license application and each license renewal form. In the absence of the submission of a specific written request to change that address, which must be separate from any other submission, the risk manager's current address is presumed to be the address on file with the department. Such address will be considered the risk manager's last known address for the purpose of notice to the agent by the department. Any request for a change of address must be made using the instructions provided on the department's website.
