I don't know but it's just a thought. Video the horse! With your farrier and in every other situation where she is a danger to you or family members. I do realize a contract is in place but I won a simular case in NC. It's called "missrepresentation" you in good faith bought a horse "he" owned. If he told you the horse was safe, sound, a cribber, crazy .......etc, (you see what I am saying?)then the dang horse should be what he was selling. It's not like you came to him and begged to buy the horse, right? He (I'm sure) advertised in some fashion for potential buyers. Find the ad, or however you found out about the horse and how he was representing it. And go fight like mad. Personally I would be fighting to get 100% of my money back and he can keep that horse. So counter sue for your money back. I don't care if he's a judge, he's done you wrong and he is trying to bully you around......just because he is a lawyer. Try to clear your head of the hurt you are being inflicted by him and get your ducks in a row (so to speak) pull all of your resourses together and go get him.
I won my case! Good Luck!!!
