Division of Contributions
There are generally two types of money in a 401(k): employee contributions and employer contributions. A proper QDRO should specify how each type will be divided. In most cases, the order will assign a percentage or fixed dollar amount based on the account’s value as of a specific date, usually the date of divorce or separation.
Failing to specify the valuation date can result in an unequal or unintended division. Be clear and precise in your order.
