According to NAR guidelines, the listing broker is required to disclose the amount of compensation being offered to cooperating brokers on each listing filed with the service. This ensures that cooperating participants are aware of the compensation they will receive before starting their efforts to sell a property. Disclosure of this information is necessary for transparency and fair cooperation among participants. You are allowed to inquire about the cooperating commission without needing to have a buyer lined up for the property already.
