I have a friend who looks pretty poor on paper, and also another one who keeps most of his assets in offshore corperations and in non dollar, non yen, non euro based hard currency assets.
If none of those where available my friends would probably keep under $100,000 in any number of banks, however with the fed stealing your money by default (low rates, inflation, declining dollar) that's not the best option available, athough IMHO the dollar is about done declining Vs the Euro. Farm land owned by said offshore corps is probably not a terrible investment if I was to give advise to a friend. If you have friends worried about asset protection (and anyone with money should worry about it) I'd suggest them seeing a good attorney, and then using a lot of their own common sense, which assume hopes and assumes they have some. Of all your above mentioned options owning stuff with your spouse is probably the dumbest, although the dollar has fallen nearly 50% in the last year or so, so in that regard Uncle's Al and Ben have already done to you what the courts would if your sig other leaves you.
