Which document serves as proof of employment by a seller for a broker in order to collect a commission?

The listing agreement serves as proof of employment by a seller for a broker in the context of collecting a commission. This document establishes a formal relationship between the seller and the broker, outlining the terms under which the broker will market the property and secure a buyer. It specifies the commission rate, the duration of the agreement, and the responsibilities of both parties. This legal binding agreement ensures that the broker is entitled to receive a commission upon successfully facilitating a sale, reinforcing the broker's role as the agent in the transaction.

In contrast, the deposit receipt is primarily used to document the acceptance of a buyer’s deposit when making an offer on a property, and it does not serve to establish a formal relationship for commission purposes. The escrow agreement involves the handling of funds and documents during the sale process, but it does not pertain to the employment of the broker. The purchase contract, while crucial for detailing the terms of the sale between buyer and seller, does not confirm the broker's right to a commission, which originates from the listing agreement.
