Wait, that doesn't make any sense. He's dead. Half of HIS assets should transfer to YOU.
Not if he didn’t leave a will. It goes to his offspring. His 2 children he had after he left me were adopted by someone else and they still are entitled to an equal share of my assets. I can go to court and try to prove he was not entitled to half of my assets, but I have to find people to testify that will not gain from their testimony. Unfortunately, at this time, most that knew the situation have passed on. I have to find two people, but so far only have one.
Find another lawyer. If he abandoned the marriage and financial support for your children, he should be paying you from his estate. If they make you pay one penny, you should buy a small classy motorhome and move around d RVs parks for the rest of your life.
