My daughters trainer...lets call her sally...found a horse for my daughter. When we went and picked up the horse, Sally told the lady that she was giving the horse to my daughter. The lady said that was fine and that we didn't have to sign a contract because she knows Sally. Well Sally decided that she doesn't want anything to do with it anymore and calls rescue lady and tells her that we are not feeding the horse enough. Now rescue lady wants us to sign a contract. Would we still have rights to the horse if we refuse to sign?
