Employer Contributions and Vesting Schedules
One critical detail is whether the employer made contributions, and if so, whether the participant is fully vested. Many 401(k) plans tie employer contributions to a vesting schedule—often based on years of service. If your spouse isn’t fully vested, you may not be entitled to any unvested employer match. That said, the QDRO must be carefully worded to differentiate between participant contributions, vested employer contributions, and unvested employer amounts that could be forfeited.
