Legal Question in Family Law in Iowa

That's a discussion you need to have with your attorney who is representing you. It may be that what was contributed before you were married is not property of the marital estate.

Generally speaking the marital portion of a 401(k) is divisible. That means that the part which was acquired during the marriage can be divided. There are some other unique situations, which may be an exception to this general rule. However, if you are headed toward a divorce you may want to discontinue contributions now and pick them up following your divorce. Perhaps you have debt or other current obligations that could be serviced by those funds. Seeking legal advice can help you make those decisions.
