A real estate salesperson selling a property listed by another broker is directly responsible to his or her broker, as they work under the broker's supervision.
Step-by-step explanation:
In the context of real estate transactions, a real estate salesperson who is selling a property listed by another broker is directly responsible to his or her broker. This is because real estate agents work under the supervision and guidance of the brokers that employ them. The salesperson's allegiance and responsibilities are first and foremost to their employing broker, who in turn is responsible for the listing agreements with owners and potentially the multiple listing service (MLS).
