What about setting up a "Family Trust" instead? ... I'm not even sure that you have anything like this in the US but I'm assuming you do.
Everything you own then becomes owned by the "Trust". Normally you control the "Trust" or you can nominated someone else to control it. AT ANY TIME... (Hint Hint)
There's are not exclusive to rich people. IMO If you own your house you need a "Trust. You can also secure things like furniture and cars in a "Trust".
It's becoming more and more common in Australia for people to secure their assets this way.
That way your kids will get what's coming to them regardless of what may happen in any future relationship.
BUT "Porsche-O-Phile's" Post is worth reading over and over again.
