There can be reasons for a participant in an employment-based retirement plan to prefer it over an Individual Retirement Account.
Among them, opportunities for guarding a retirement asset from some kinds of creditors’ claims might be better with an employment-based plan (even if not ERISA-governed) than an IRA. This might be so not only under bankruptcy law, but also under other laws. As CuseFan suggests, there is no shortcut; one must get into the details of those laws and how they might apply to facts and circumstances the individual plans against.
The individual might want not only legal advice but also practical advice across her whole team of advisers, including lawyers (for each topic), certified public accountant, physician, actuary, financial planner, investment adviser, and TPApril.
This is not advice to anyone.
