My mother just passed away on May 5th. She did have a will but the executor is my deceased grandparents. My step father has numerous credit card bills and medical bills coming in. What is he legally responsible for paying? Does he have to go to probate? Please help me by telling me what he needs to do and if he has to pay her medical bills. They really dont have a savings. She only had a 401k, a life insurance policy to cover funeral expenses, and an annuity for my brother and I. Her house is very old and in bad condition to try to sell.
