Employee and Employer Contributions
This type of 401(k) plan likely includes both employee deferrals and employer contributions. That’s important, because:
- Employee contributions are always 100% vested and subject to division.
- Employer contributions may be subject to a vesting schedule—meaning the participant may not be entitled to all employer-funded balances.
The QDRO must clearly define whether it includes just the vested portion or all contributions as of a certain valuation date. If this isn’t spelled out properly, the plan administrator could reject the order or misinterpret the intended division.
