...this will leaves 100% to only one child. It is witnessed by this same child and 1 other person. It is not notarized. I am told this will is invalid and that intestate rules apply. There are many emails btwn the 2 children agreeing to an even split but now the 1 in the will chg'd mind and is making threats if he isn't paid all. What to do? Can this be sent to probate court for a judge to decide? The child named in the will and who wants all lives 3000 miles away. Does he have to appear in PA or will judge proceed with/without his presence?
