The wealthy have made themselves invulnerable to lawsuits. As wealth managers have made fortunes by putting clients funds into Cook Islands asset-protection trusts, clients such as the Rothschilds and the lesser known wealthy families of the world have done. In effect, such trusts make these fortunes essentially immune from the application of inconvenient national laws.
It seems that no litigant on earth has been able to break a Cook Islands trust, this includes the U.S. government, which has repeatedly been unable to collect on multi-million-dollar judgments against fraudsters convicted in federal court.
So when you get to that point, you have some idea of what to do, with the funds.
