How to find a deceased persons Will?

I assume that you have questioned the deceased's friends and other family members. If that's been of no use then if they had a safety deposit box I'd start there. If that's not successful then go through any papers that you can find in desk drawers, file cabinets, the pages of a family bible or the like. Check eveywhere. If you still don't find a Will be on the look out for a letter or business card from an attorney; you can contact them and ask if they drafted one for your grandfather (if the attorney has retired you can contact the state bar association to get their contact information).  If you can't find any information about an attorney, then try contacting other advisers that your grandfather may used; a financial planner or an accountant. You can even just start calling attorneys in town to see if they drafted a Will for your grandfather. Additionally, you could also place a "Lost Will" ad in the local paper. Further, you can check with the Probate Court in the county where he resided; it is possible that a Will was filed with there when it was executed.
