Insurance, insurance, insurance!
Contract, contract, contract!
Cover your backside, cover your backside, cover your backside!
My Mom is boarding my cousin's 2 horses (pasture with run-in shed) - only $150, total. Dirt cheap. But then, like it said it's for her niece, who is in really tough times right now... so take that into consideration. And no - no contract, she doesn't have it covered by insurance; big mistake in my book! But her choice to make I guess. So far everything's gone fine, she's only had them 2 months though.
