Which document is utilized by a broker to seek a commission from a buyer?

The correct choice is the Exclusive Buyer Brokerage Agreement. This document establishes a formal relationship between the buyer and the broker, where the broker represents the buyer's interests in the transaction. It specifies the terms under which the broker is entitled to a commission in return for their services, including the obligation of the buyer to work exclusively with that broker during the search for a property.

This agreement is essential in reinforcing the broker's right to seek compensation when the buyer ultimately purchases a property. It outlines the scope of services provided by the broker and the expectations from both parties, ensuring that the broker is compensated for their work, regardless of whether the property is listed by another agent or is a private sale.

In contrast, the other choices serve different purposes. A Purchase Agreement is the contract that outlines the terms of buying a property once a buyer decides on a specific property. The Listing Agreement is between a seller and the broker to market a property for sale, and the Sales Contract is an agreement that details the transaction of a property between the buyer and seller. None of these documents establish the exclusive representation needed to allow a broker to rightfully claim a commission from a buyer in the same way that the Exclusive Buyer Brokerage Agreement does.
