For most real estate transactions, the Buyer and Seller will use a real estate broker. To sell your home, the real estate broker will want a listing agreement signed. You should consult a lawyer before signing the listing agreement. It is a binding contract when signed by both parties. In the same way, the Buyer should understand the Buyer/Broker’s form before signing. This could potentially obligate the Buyer to pay all or some portion of the real estate commission.
