1. Employee vs. Employer Contributions
401(k) accounts typically contain both employee salary deferrals and employer contributions. From a QDRO perspective, both components may be divisible. However, certain employer contributions might be subject to a vesting schedule.
- Employee Contributions: 100% vested immediately.
- Employer Contributions: May be partially or fully unvested, depending on the participant’s length of service.
If the QDRO attempts to divide unvested portions, the alternate payee may receive nothing unless the participant meets vesting criteria in the future. That’s why understanding the plan’s specific vesting rules is critical to avoid overpromising an amount that won’t actually be paid.
