Could you just use a standard loan agreement, and add in that you are paying the installments, and at the end the horse will become yours? It sounds like effectively you will have the horse on loan until you have finished paying. I think you can find a sample loan agreement on the BHS website
Am buying a horse . But am paying small deposit then will start to pay the balance in October. We want some kind of agreement that although horse is solely hers until full balance is paid off that any veto airy treatment I am liable for and that if she was pts or similar I still have to pay the full balance. Can anyone help?
