I doubt it; I think it will go to Anna Nicole's baby daughter. Most state probate statutes allow for inheritance by children born after the decedent made their will. The rationale is that the decedent intended for their child to inherit, even if they didn't get around to changing the will to include the new child.
But then the issue falls back on paternity. I know under Bahama's slender law there is apparently no procedure to challenge paternity--it is whatever the mother states on the birth certificate. But the estate will be probated in the US--California I assume. It will have to force the hand of Stern because I can't imagine a court in California not requiring a paternity test to decide who will be the guardian over this child's estate. At the moment the only uncontestable next of kin under US jurisdiction is Virgie.
