It also provides that if the acomptère is paid to the seller as lump sum damages, all trust and cancellation fees for the title are paid by the seller. If a broader arbitration clause is to be desired, the separate arbitration contribution from the AIR form should be used. But even this endorsement has limits to what is covered by arbitration. Most “commercial brokers” use the AIR form when representing a seller because it has a passive (automatic) removal of contingencies. CAR forms are normally used when the broker is not a member of the AIRCRE organization that authorized these forms. The CAR form is usually more advantageous for a buyer. I am a member of both organizations and use AIR and CAR forms. I also used CAR forms for sellers, as with everything, it all depends. .
