Employee vs. Employer Contributions
401(k) plans usually include both employee salary deferrals and employer-matching contributions. Spouses may be entitled to a share of both.
However, employer contributions often come with a vesting schedule—meaning the participant doesn’t own 100% of them right away. Your QDRO must clearly state whether it divides only vested employer contributions or if it allows the alternate payee to benefit from later vesting.
