The payment of compensation or the obligation to pay compensation to an agent by the seller or buyer is not necessarily determinative of a particular agency relationship between an agent and the seller or buyer. A listing agent and a selling agent may agree to share any compensation or commission paid, or any right to any compensation or commission for which an obligation arises as the result of a real estate transaction, and the terms of any such agreement shall not necessarily be determinative of a particular relationship.
