1. Employee and Employer Contributions
Most 401(k) plans allow voluntary employee deferrals and may include matching or discretionary employer contributions. In a divorce context, you’ll want to specify the correct assignment strategy:
- Shared Interest Approach: Participant’s account is divided based on a percentage (e.g., 50%) as of a certain date (often the separation or divorce date), including all gains and losses.
- Separate Interest Approach: The alternate payee receives their own account, composed of the assigned portion, and can choose future investment options independently.
If employer contributions aren’t yet fully vested, those amounts may not ultimately become part of what’s divided unless the participant remains employed long enough to vest fully. Your QDRO should make clear how to handle any later vesting.
