In my state if you sign a buyer agency agreement, describe the property you are looking for and it is dated. You are obligated to pay in most situations. If you can prove abandonment you can likely get off the hook. Every state has their own laws and rules so be certain know what those laws and rules are. Also read the contract carefully. In my state there is a clause that if the listing broker doesn't pay the buyer agent, or doesn't pay enough to satisfy your fee, you are obligated to pay. I never liked that sentence. Thanks for your questions
