Which of the following listings would allow more than one brokerage firm to work simultaneously to sell the owner's property and claim the full commission?

An exclusive listing grants a single brokerage firm the sole right to market and sell the property. Under this agreement, the owner cannot engage other brokers to sell the property, which means that only the exclusive broker can claim the commission if the property is sold. Thus, it does not allow for multiple brokers to work simultaneously.

A written listing refers to any listing agreement documented in writing, which can be exclusive or non-exclusive. Therefore, it does not inherently imply that multiple brokers are allowed to work on the sale. The nature of the listing—exclusive or open—determines whether more than one broker can claim commission.

An exclusive right-to-sell listing provides one brokerage firm the exclusive authority to sell the property, ensuring that the brokerage earns the commission regardless of who finds the buyer. This means no other brokerage firms can work on the sale simultaneously, making it incompatible with the idea of multiple broker participation.
