Employee and Employer Contributions
Most 401(k)-style plans have both employee and employer contributions. While employee contributions are immediately vested, employer contributions may be subject to a vesting schedule. You’ll need to clarify in the QDRO whether the alternate payee (usually the non-employee spouse) is entitled to only vested amounts or a portion of unvested contributions as well.
This detail has major financial implications. If the plan participant hasn’t been with the employer long enough to be fully vested, the alternate payee could miss out on significant funds unless the QDRO addresses this clearly.
