Employee vs. Employer Contributions
401(k) accounts commonly include both employee deferrals and employer matching contributions. These components must be clearly defined in the QDRO:
- Employee contributions are always 100% vested and divisible without restriction.
- Employer contributions may be subject to a vesting schedule and require extra attention. Unvested portions usually stay with the participant, but your QDRO should clarify this outcome.
If employer contributions are not yet fully vested at the time of divorce, the QDRO can state that the alternate payee is only awarded vested amounts — or that they’re awarded a percentage of whatever becomes vested later. Failing to address this detail can lead to fights down the road.
