Indeed. It's called an "insurable interest." Parents are usually presumed to have an insurable interest in the lives of their children, although I'm not sure if that presumption holds for adult children.
In any event,
peacenlove, there's not much a person can do to have a life insurance policy on his/her life cancelled. I suppose you could call the insurance company and tell them that there's something fishy going on here, but as long as your mom is paying the premiums and there's no evident fraud involved, I don't think it's possible to have a policy on your life cancelled if you're not the owner of that policy.
