I think this is a scam... Owner died, bought horse, decided to sell.For all the OP kinows, the papers are false. Not traveling to see horse or find someone to go see horse for that amount of money is not real smart.
If the lady won't answer, what about the farm owner/manager? What about the registry? Call them and explain what is happening and maybe they can help with information.I would be calling the farm, the farm owner, the farm manager, any contact named over and over until someone answers. With the internet, it is so easy to take a photo, put up and ad, make false papers and sell said horse without anyone actually even looking at the horse in person. Happens alot .
Unfortunately, if it sounds like a good deal, then its probably false.
I am not sure you can even go to court if there is no contact with the lady who sold you the horse, she will have to be served before you can go to court. You will have to have a physical address for her to be served and she probably even lied about that.
