Employee vs. Employer Contributions
This plan likely includes both employee elective deferrals and employer contributions (matching or discretionary). The employee contributions are always 100% vested, but employer contributions may be subject to a vesting schedule.
Your QDRO should clarify whether you’re receiving a share of the total vested balance or just the portions contributed during the marriage. It’s also essential to confirm whether unvested employer contributions should be excluded from the non-employee spouse’s share.
