I have done in the past, but don't think I would again. I sold Jed using a 3 month trial/lease. I had a lengthy contract in place, and had full details of the owner (down to drivers lic, etc), and off he went. I only allowed him to go for 2 reasons - one. I had a GOOD gut feeling, and two. They lived a good couple of hours away. Three (yes i can't count LOL). I had a very detailed contract. It worked out beautifully, he's still with the family and I honestly couldn't have asked for a nicer home for him. (hello if you're reading this!! ) But I don't think I would again .. purely because I don't trust people LOL! On property is fine, but I'd still have a contract in place. I do think trials can work, for sure, but I wouldn't let the horse go off the property again. I am super happy how it worked out with Jed though! I think that it's difficult to buy a horse without having a trial, one ride doesn't really show their true colours.
