Employee and Employer Contributions
This plan likely includes both employee salary deferrals and employer contributions. The QDRO has to specify whether the alternate payee (typically the non-employee spouse) is entitled to a portion of both types of contributions or just one.
Some employer contributions may only partially belong to the employee, depending on the vesting schedule (more on that below). A proper QDRO needs to separate vested from unvested funds and state whether the alternate payee gets anything from partially vested accounts.
