If I’m reading this correctly, the money in the children’s Trust is untouchable in the civil case. By adopting the 42-year old and giving her 1/3 of the Trust, he’s really only taking money from his children. His assets (those not in the Trust) are up for grabs in the civil suit. I guess his kids could be pissed, but hell, it was his money in the first place.
I agree, it kind of sounds like what you described, but it makes little sense for him to do that. I think somehow, he must be pushing some of his non-trust assets to his gf.
 Not really since he gave the money away, deeming it exempt property from creditors. Maybe his kids are angry at him for whatever reason and refuse to participate in the sham. Thus the girlfriends adoption so he can get his grubby hands on it judgement free.
