Once you’ve selected a REALTOR® to market and sell your property, you and the agent will  enter into a written, legally binding contract called a listing agreement. This standard form  (RLA; Exclusive Authorization and Right to Sell) stipulates all agreement terms, including the listing price, the listing time period, the broker’s commission and more. It also informs the seller of issues and legal requirements that may be involved in the process. (www.car.org)
