1. Division of Contributions (Employee and Employer)
Most 401(k) accounts include both employee salary deferrals and employer contributions. These components may be impacted by:
- Vesting schedules: Employer contributions are often subject to vesting rules. Only vested portions can be divided under a QDRO. Any unvested contributions at the time of divorce become irrelevant to division unless the participant later vests and the QDRO specifies future entitlement.
- Marital portion definition: Your QDRO should define the “marital portion” (e.g., based on contributions made during marriage) and explain how earnings and losses are applied up to the date of division.
