Do I have any right to the value of these after 30 years of marriage
As a surviving spouse you are also likely to be entitled to the first $20,000 of your late husband's estate as a widow's award. Whatever you do, don't be bullied by his kids -- get a lawyer ASAP.
Under Illinois law, when a married person, who also has children, dies without a will, the estate is divided up by giving the spouse 1/2 of the estate and the other 1/2 of the estate is divided evenly among the children. How the estate is divided is up to the person who will eventually named the executor by the court. I suggest that it may be in your best interest to ask the court that you be named the executor. I also think that Stephanie Sexauer can do an excellent job for you.
I’m SO sorry to hear about this; how awful.
