Call the agent or appointment and explain why you want to terminate the contract. For example, if you simply changed your mind about the sale, it is unlikely that the agent will tackle the cancellation, because there is no commission. It is important to know that it is the broker who owns the list, not the listing agent. If you wish to resign because you are not satisfied with the listing agent`s service, the broker manager could easily assign another agent who is with you from the same office, in which case you would not have to terminate the listing agreement. If you resign for another reason, you must work with the agent and broker. Most exclusive listing agreements include a section on expiration or early cancellation. It is customary for the contract to expire on its own within a specified period – such as six months – during which the seller can choose another agent without penalty.
