Typically the Listing Agreement provides for the fee to be split between the Listing Broker and the Selling Broker (Buyer's Broker). If you clearly found the Buyer, then it stands to good reason that you would only have to pay the Listing Side Fee. So if you signed a 6% deal, and your Listing Broker agreed to share that 50/50 with the cooperating broker, then you would need to pay out at least 3%, but maybe no more than that. Of course you (or your attorney) need to refer to the actual language of the listing agreement you signed.
The main complication you may have is determining who is the Procuring Cause of the Buyer. Depending on your State, it may say that whoever wrote the offer is the Procuring Cause. So if your Listing Broker also wrote the Purchase Contract for the Buyer, then the Listing Broker is likely to be entitled to the Full Fee.
