Employee and Employer Contributions
This plan likely includes both employee deferrals and employer contributions. Employee contributions are usually fully vested, but employer contributions might be subject to a vesting schedule—especially if based on years of service. If your QDRO attempts to divide funds that are not yet vested, you could run into rejection or delays.
Make sure the QDRO clearly references only vested balances or includes a provision about how to handle unvested amounts that may vest after the divorce but before distribution.
