Legal Question in Wills and Trusts in California

I would file for probate either as special administrator or as if there is no will. I would then continue the search for the will. One possibility would be to contact all lawyers who prepare wills near where your grandfather lived. Unfortunately sometimes people die and their wills can not be found. In that case the laws of intestacy would prevail. Quite often those laws are what the will said anyway so often not a big deal. I encourage you to talk to a qualified probate attorney to go through your options. Contact me if I can help. I am a certified specialist in probate law and work throughout the state.
