This forum is the last place a person should go to get advice on a subject like this.
Having said that, I am going to offer thoughts that are not intended to be advice, but rather a defense of the offshore concept as it has been often misunderstood and maligned.
I was a stockholder and director of an offshore company for over 25 years. We constantly had meetings with lawyers and accounts to be sure we were legally complying with the complex laws of doing offshore business. Offshore companies and the bank accounts of those companies are intended to allow those entities to do business in a legal way, legal being the important word, when that business operates in the jurisdiction of more that one country without coming under, primarily, the tax laws of those countries as an individual would. We eventually had to pay taxes as individuals on any profits we made through those companies to our respective countries of residence.
Granted, there have been uses of the offshore banking industry to illegally hide money or evade taxes on that money. But those incidences are against the laws of those countries and when they are uncovered, they are not protected. One example is James Gibson. He was a US citizen who obtained Belize citizenship and had money in a Belize bank that was illegally obtained, according to a US court. He mistakenly believed that it was protected from the US courts. He is currently serving 21 years in a US prison and his money is in the hands of the US court.
If this fictitious person has a judgement against them from a court, he best pay that judgement or get an attorney to fight it within that jurisdiction. Whoops, I guess that sounds like advice - sound advice.
