Employee vs. Employer Contributions
The QDRO must distinguish between what portion of the participant’s account is from employee deferrals (always 100% vested) and what portion comes from employer contributions. Employer matching contributions—common in plans established by general business entities like Unknown sponsor —may be subject to a vesting schedule. Only the vested portion is eligible for division via QDRO.
For example, if the participant is only 50% vested in their employer matching funds at the time of divorce, the former spouse can only be awarded 50% of those matching contributions in addition to any share of the employee contributions.
