Protecting my investement for my son.

If you established an account prior to your second marriage, and it was funded only prior to the second marriage, a court would likely find that it is your separate money, and the second wife would have no claim to that account.  If the account was funded in part during the second marriage from your earnings, than it is either wholly marital, or if you provide a proper accounting of which parts were premarital and which parts were marital, then the court could find it part separate and part marital, and your second wife would have no interest in the separate part.  If you contend it is not your money, and you were holding it in trust for a third party,  you would need to show that you did not treat it as your own.
