A sales agent may work from an office location different from the main office of the sales agent's sponsoring broker, but the sponsoring broker is still responsible for the sales agent's actions. [TRELA §1101.803, Rule 535.2(a)] Despite this flexibility, a sales agent may not lawfully engage in brokerage activity unless the sales agent is associated with, and acting for, the sponsoring broker at all times. [TRELA §1101.351(c)] Thus, a sales agent may not work for a broker who is not the sales agent’s sponsoring broker or work for another broker or out of another broker's office.
