If you cannot accept the following, you may not be ready to sign a buyer-broker agreement. In the following situation, the original broker is not without remedy. As long as the original broker can prove that he or she was the cause of the buyer`s purchase, the original broker should be entitled to the co-broke commission offered by the new listing broker in the Multiple Listing Service (MLS). And according to the mlS Clear Cooperation Policy: „Within one business day after a property is marketed to the public, the listing broker must submit the listing to the MLS to collaborate with other mls participants.“ See www.nar.realtor/about-nar/policies/mls-clear-cooperation-policy. .
