Up in the clouds
Got legal advice, they are in breach of contract, and the horse became mine as soon as they confirmed receipt of sale. So I was told to write them an email stating that they were in breach and see what happens.
Not sure what to do in meantime though.
I would hack off the yard and keep him somewhere else, even if you have to put him in temporary accommodation. Then send the email. I wouldn't email them while he is still on the yard, just in case some harm befalls the horse.
