Employee and Employer Contributions
401(k) plans have two components: employee contributions (which are always 100% vested) and employer contributions, which are often subject to a vesting schedule. In a QDRO, a former spouse can generally only receive a portion of what’s actually vested as of the date of division.
If the employee is not yet fully vested in the employer match portion, your QDRO must clarify whether the alternate payee gets only vested amounts as of a certain date or whether they share in future vesting. The plan document will ultimately govern this — and failing to address it upfront can delay approval.
