Employee vs. Employer Contributions
401(k) plans usually include both employee and employer contributions. Under ERISA, only the vested portion of the participant’s employer contributions can be divided in a QDRO. For example, if the participant is partially vested due to a vesting schedule (common in business entity plans), only the vested share can be assigned to the alternate payee.
If the employee isn’t fully vested at the time of divorce or QDRO approval, this will directly affect how much the alternate payee can receive. A clear QDRO can address options such as:
- Receiving only the vested portion at the time of order
- Delaying assignment until full vesting is achieved
