1. Employee and Employer Contributions
401(k) accounts frequently include both employee and employer contributions. The QDRO must clarify whether the alternate payee is receiving a portion of just the vested account or the entire balance. Employer contributions may be subject to a vesting schedule, which determines what portion is actually owned by the participant at the time of divorce. If any portion is not vested, it will generally be forfeited and cannot be awarded to the alternate payee.
