Employee and Employer Contributions
The QDRO must clearly identify which contributions are being divided. Employee contributions are always 100% owned by the participant, so they are fully divisible. However, any employer matching contributions may be subject to vesting. If the participant is not yet fully vested at the time of the divorce or QDRO, the alternate payee may not be entitled to the unvested portion.
This creates a potential conflict if the divorce judgment awards a percentage of “the total 401(k)” without accounting for vesting. Always check the plan’s vesting schedule, which should be in the Summary Plan Description (SPD) or available from the plan administrator.
