If Betty gives multiple types of listings to different brokers, who is generally entitled to a commission if one of them sells the house?

When multiple brokers are involved in the listing of a property, the entitlement to a commission typically goes to the broker who successfully closes the sale. This is foundational to real estate practices, where the broker who brings a buyer to the table and finalizes the transaction is rewarded with the commission.

In situations where a seller provides multiple listings to different brokers, the commission structure is governed by the type of listing agreement in place. In an exclusive right to sell agreement, the designated broker would indeed be entitled to a commission regardless of who procures the buyer. However, since the question does not specify that such an exclusive agreement exists, it's understood that if a sale occurs through one of the brokers’ efforts, it’s the broker who concluded the transaction that earns the commission.

In contrast, the other choices imply scenarios where multiple brokers or listings could potentially claim entitlement. However, the standard practice upholds that without specific contractual agreements granting shared commission rights among others (which generally isn't the case with open listings), the successful broker receiving the commission aligns with industry norms. This scenario illustrates the foundational principles of brokerage agreements and commission structures that govern real estate transactions.
