Ouch. Never, ever, (can't put in enough never's ) do this. Life insurance is just that, insurance when there is loss of life. If there is a beneficiery such as a spouse, legally there is nothing the hospital can do to take that money.
I really try to be a responsible person and it would take a lot for me to say "don't" pay off a debt I occured but I am recently a widow, my wonderful dh of 25 years lost his battle with luekemia.

Because he was a wonderful man his life insurance will allow me to continue to live the life we planned on. My children will finish college and I will be financially secure for the rest of my life. Would I trade it all back in a nanosecond for 1 more day with my boo. YES!! but now that I am the sole responsible parent for my kids sorry I would never ever use my life insurance to pay any bill.
