Which one of the following is legally entitled to sue a seller for a commission when the buyer was represented by a subagent?

The listing salesperson typically works under the authority of the listing broker and does not have a direct contractual relationship with the seller. Therefore, they do not possess the legal standing to sue for a commission; that right belongs to the broker they represent.

Similar to the listing salesperson, the selling salesperson represents the buyer and is not in a contractual position with the seller. Their role is to facilitate the transaction on behalf of the buyer, but they lack the entitlement to sue the seller for commissions, which is a right reserved for brokers.

While the selling broker may have a contractual agreement with the buyer, they do not have a direct contract with the seller unless specified otherwise. The selling broker may negotiate terms, but they cannot sue the seller for a commission in instances where the seller’s obligations are fulfilled through the listing broker.
