I have received a life insurance payment for my mother, how can I cash the check to pay for funeral expenses,? - probate litigation

I have power of attorney for my mother's business, but I moved from one state to another. I have the payment of life insurance as she moved, and the succession process is still controversial because of a greedy aunt.
I have to pay the funeral expenses, legal fees move for succession and expenses for medical evacuation, she left the bag.
Who or how do I change change your life?
