Leasing can be very exciting and rewarding.:). Some things: make sure the contract is specific about costs and names EXACTLY what your costs will be. Is the base lease cost inclusive of everything or could there be surprise add one..for example a surcharge if the price of feed, farrier, etc goes up. Who is responsible for vet care and followup? What are your responsibilities as lessee in regards to care both in daily riding and/or vet? Is there anything they do not want the horse to do? Policy for off property travel if you decide, and they approve, to show. For example..when I did a half lease on my horse, it was very clear that he was to be booted for any exercising; he was limited to jumping to only four times a week with no height higher than 3' 6". Lessee was responsible for any and all costs related to her own shows and that included any vet costs if the horse was injured or got sick either due to or while being off property. This included cost of farrier if he threw a shoe at the show. For the most part I kept full care of the horse related to vet, farrier etc as I am just paranoid that way...:). She also had vet authority to call but had to let me know ASAP and I retained approval for any major care; the vet had a letter from me detailing her level of care authorization. One other thing; if you are under 18 you may need to have a parent sign as well.
