I get asked all the time whether I can find hidden bank accounts around the world. The answer is mostly no. Brian Willingham of Diligentia Group wrote a helpful article about this last year, entitled “Can a Private Investigator Get Bank Records or Account Information?”. His answer is also no.
There are laws in place to protect your financial privacy. So if a private investigator, forensic accountant, or other professional tells you that they can find hidden bank accounts, you can be assured that they are using dishonest and illegal means to do so.
