From my understanding, ERISA accounts are fully "protected" from bankruptcy or garnishment. You can still be hit with a court award of say 1 million. You would have had to ignore the court order and not pay (forever) , or file bankruptcy.
Federally, IRA's and Roth IRAs are currently protected in bankruptcy up to $1,362,800 (https://www.thebankruptcysite.org/ex...s/federal.html
) That amount is adjusted year to year. States' laws vary on these accounts.
I may be misunderstanding this. Do not use this info for your financial planning. Seek confirmation.
