As long as the investments are still held in the IRA rollover account, they should be protected in bankruptcy as well as from a judgment creditor. Speak to the manager of the institution for further information about how they act to protect their depositors. Hope this perspective helps!
I agree with the attorneys that have answered already, As long as the retirement meets the definition under the Internal Revenue Service, it will be protected from the trustee. Of course you should discuss this with your attorney.
