A child born during a marriage is presumed to be the husband's. After two years, if unchallenged, that presumption holds, unless the bio father appears, and the named father, bio father and mother are of one accord, and the court accepts, that the bio father should become the legal father. There may also be room for the two year clock to be on hold if the husband is active military. You do not indicate how old the child is, and it is not in son's favor that he has apparently not challenged the paternity before a divorce went through, but seeing counsel is necessary if there is any opportunity to undo the lack of action to date.
