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 sell the property, preventing any other broker from acting on behalf of the owner. In this arrangement, the designated broker is entitled to the full commission regardless of who sells the property, which eliminates the possibility of multiple brokers claiming a commission simultaneously.

A written listing refers to any formal contract between a property owner and a brokerage firm. This type of listing can be either exclusive or open. Therefore, it does not inherently allow for multiple firms to claim commission, as the structure of the agreement dictates whether exclusivity exists or not.

An exclusive right-to-sell listing gives one brokerage firm the exclusive right to sell the property, ensuring that they receive the commission no matter who sells it. Similar to an exclusive listing, this arrangement prevents multiple brokers from simultaneously claiming the commission.
