Employee vs. Employer Contributions
It’s crucial to distinguish between employee contributions (which are always 100% vested) and employer contributions, which may not be fully vested. The Mpf Federal LLC 401(k) Plan likely has a vesting schedule, which can limit what a non-employee spouse is entitled to. Your QDRO should specify whether it includes only vested employer contributions at the time of division or if it will be adjusted based on future vesting.
