Final answer:
In a real estate transaction where the broker represents the seller, a salesperson under that broker acts as a sub-agent, aiding in representing the seller's interests.
Step-by-step explanation:
If a broker represents a seller in a real estate transaction, a real estate salesperson working under the broker will typically serve as a sub-agent. In this role, the salesperson owes the same fiduciary duties to the seller as the broker does and is tasked with working on behalf of the seller to assist in the sale of the property.
The salesperson does not act as a customer, client, or consultant in this relationship, but rather as an extension of the broker, aiding in the representation of the seller's interests.
