Employee and Employer Contributions
In most 401(k) plans, a participant contributes pre-tax salary, and the employer makes matching or discretionary contributions. In a QDRO, both sources of funds can be divided—but there’s a catch. Employer contributions may be subject to a vesting schedule. If your spouse is not fully vested, you may not be entitled to the entire employer-funded portion.
For example, if only 60% of the employer’s contributions are vested, only that 60% is available to be divided. The remaining 40% may be forfeited upon separation from service or divorce, depending on the terms of the plan. The QDRO should clearly define the cutoff date (usually the date of marital separation or divorce) for determining which funds are included and how vesting is measured.
