I sent my horse to a trainer 16 months ago. We had a verbal agreement that I would pay 400 dollars a month I have been doing so every month since he got there. In June I had emailed him asking if I could lease my horse on his property he said no but offerd me a deal. The deal was hed take ownership of the horse until I was finished school in that time he would not sell him and I would pay 1000 to get him back. Unless he died in which case the horse would go back to me no charge if he had to sell the horse due to extreme circumstance I would be able to have first choice to buy him back for 1000. I did not have to pay anymore after the month of june. My mom sent him an email on June 28th saying we appreciated what he was doing and I just needed time to think but we were probably going for it. They did not respond to this email on July 9th I had sent them one clearly stating I was accepting the offer and for it to start right away and to draw up a contract. He did not respond so I assumed it was a go. He emailed me recently 2.5 months later asking why I haven't paid board and that my email back in July was confusing. He is saying I owe him 1200 dollars by the end of the month or he is selling my horse.He did not tell me any of this until 2.5 months later I had no idea he was still expecting payment because I though the deal was going through.
My question is what is my legal action and can he legally sell my horse he has no ownership papers and I never signed a contract he is also denying we ever had an arrangement.
