1. Vesting Schedules and Forfeitures
Many 401(k) plans, especially in the business sector, use a gradual vesting schedule for employer contributions (e.g., 20% vested per year over 5 years). You cannot divide unvested funds in a QDRO—even if they’re listed in the account balance at the time of divorce. If a participant later meets a vesting milestone after the divorce, those amounts are not retroactively shareable unless the QDRO includes specific forward-looking provisions. Working with an experienced QDRO attorney ensures these rules are properly addressed so no expected money is lost or misallocated.
