Which of the following is true regarding a sales agent's commission?

A sales agent's commission must come solely from their authorized broker because the relationship between a sales agent and a broker is legally defined, establishing that the broker holds the license and is responsible for the actions of the sales agent. This means that any compensation, including commissions, is legally required to be paid through the broker, who then may share it or distribute it as they choose among their agents. This structure ensures accountability and adherence to relevant laws regarding real estate transactions, as brokers are responsible for their agents' compliance with regulations and ethical standards.

In this context, while commissions may sometimes be split among agents, it is ultimately the broker who determines how commissions are distributed from the sales generated by the agents they supervise. This reinforces the principle of broker oversight and protection of consumers within real estate transactions. Other options may imply aspects of commission handling that are either not permitted under real estate licensing laws or misrepresent the legal framework of broker-agent relationships.
