"You sure ain't.  Such legal fictions bother a lawyer not at all.  Smith is legitimate different ways in different jurisdictions, all kosher and all breaking his way - even though he is probably a bastard in his physical ancestry.  So he inherits.  Besides that, while his mother was wealthy, both his fathers were at least well to do.  Brant was a bachelor until just before the expedition; he had ploughed most of his scandalous salary as a pilot on the Moon run back into Lunar Enterprises, Limited.  You know how that stuff has boomed - they just declared another three-way stock dividend.  Brant had one vice, gambling - but the bloke won regularly and invested that, too.  Ward Smith had family money; he was a medical man and scientist by choice.  Smith is heir to both of them."
