There are ways to pierce corporate veils, but that takes time and paperwork. Standard practice in situations where there is very valuable items or significant liability concerns is to make each item its own corporation. Shipping and taxis use this extensively. Carnival Cruise lines despite it's name on all those cruise ships does not own any of them, each ship is technically it's own corporation.
If I was Trump, I would have just to make life harder for anyone trying to collect on a lawsuit is to legally have most if not all of my assets in a trust, with me as the manager of said trust.
Exactly! Great points.
