A contract would not be negated by rising health costs unless the contract itself specifically said it could be altered or terminated under those circumstances; that is, if somene enters into a contract, they are held to its terms even if those terms become economically disadvantageous or even a hardship to them.The key thing, though, is that a contract is enforced according to its terms. You need to reference the terms of the contract itself to answer your question. If you have trouble understanding it, bring the contract to an attorney to review with you.
