This may not be true, what I heard is --
Without a will, court will decide (probation?). As he has a minor kid, the kid is definitely entitled to some part of the money.
If the assets are the total between hu*****and and wife, wife should have half of it. For the hu*****and part, wife normally has 50% of it; the other 50%, divided between all the kids.
The legal guardian of the kid (mother?) should talk to a lawyer about it.
