We actually were given a rescue horse (with no contract). Later the rescue wanted us to sign one (a story for a different day). Anyway, the contract was absolutely stupid, IMO. One of the things that really stood out (among many, but we can't go over the whole thing) is that any time, for practically any reason, they could come and take the horse from us. They also put in there that if we did not relinquish the horse willing, that we had to pay their lawyer fees to sue us for the horse
Lesson learned! I would not touch a rescue horse with a ten-foot pole, so to speak. I will not give anybody the right to take away a horse I pay for every day.
