How would i go about finding a deed and seeing if there is mortgage life insurance?

ask: "How would i go about finding a deed and seeing if there is mortgage life insurance?"

My grandfather died 3 months ago and i'm trying to take care of his finanial obligations. I'm trying to find the deed to his house that was purchased 7 yrs ago and still has a balance due. He spoke about having mortage life ins (house gets paid off, following death) I can't find any of this papper work. He had no will. How would i go about finding the deed of the house and if he had any mortgage life insurance?
