Employee vs. Employer Contributions
Most 401(k) plans include two sources of money: contributions made by the employee and contributions made by the employer. The QDRO can allow the alternate payee to receive a share of either or both. However, employer contributions may be subject to a vesting schedule, meaning the employee doesn’t fully own those funds unless they’ve met certain service requirements.
If part of the employer contributions is unvested as of the divorce date, those amounts typically cannot be divided—or may later revert to the plan if the participant doesn’t meet vesting terms. The QDRO must clearly state whether division is based on the total balance or only the vested portion.
