What to do for a situation like this?
I brought a buyer to a business owner who wasn't planning on selling just get. We made him a offer he couldn't resist. I do all the contracts, and all the negotiations and he agrees to pay the 3% in LOI. Then, before he signs the contract  he wants an attorney to look it over. Comes back and attorney says no need to pay me anymore and to cut me out but if buyer wants to pay, then that's fine. Now, seller wants to cut me out of deal after I brought him a buyer.

Anyone have this situation and how did you handle it?

Edit: Sorry I forgot the most important piece. I'm a licensed RE Broker in Texas.

Your Buyer should at least hire you as a consultant for a work around on the fee.  Your fee comes out of the sales price anyway.  Good luck.  We all have to learn this one the hard way.

I told him I would feel awful if the seller took this route. Buyer said its the principal to this point and he's got all the leverage, the cash and he was willing to walk away because he felt that I would be disrespected.\n\nSeller had his attorney call me saying he will pay me the 3% after lunch.
