Just a clarification on probate court distribution to children when there is no will
You state that grandchildren will inherit if their parent is no longer alive. The grandchildren will only get their deceased parent’s share if the parent died before the grandparent.
Sam dies leaving 3 living children (a, b, c), no spouse, no will. The 3 each get 1/3.
B predeceased Sam, then B’s children split B’s 1/3
BUT, it B dies after Sam, but before estate is settled. B’s 1/3 is paid to B’s estate and subject to B’s will and/or the probate process. The 1/3 could very well end up being shared by B’s spouse (widow/er)
