Well, the problem is, this is a PARTNERSHIP. It works with the voluntary consent of the other. If it was a corporation, you can certainly sue the corporation for canceling it, and you would most likely win the case. You would probably get a judgment against them. If it’s legally a PARTNERSHIP, and you’re a partner, technically, he’d be suing himself as well. Also, if this was an individual health policy, one would receive no liability – only if it was a GROUP policy.
