1. Division of Contributions
Most 401(k) plans involve both employee and employer contributions. With the National Council of Examiners for Engineering and Surveying Retirement, each party’s marital share should be calculated based on the participant’s account balance accrued during the marriage. Keep in mind:
- Employee contributions are always 100% vested and available for division.
- Employer contributions may be subject to a vesting schedule, which could affect how much the alternate payee (the non-employee spouse) receives.
If your divorce order doesn’t make these distinctions clear, the QDRO administrator may reject your order or improperly calculate the division.
