Employee and Employer Contributions
In most 401(k) plans, participants make pre-tax or Roth contributions from their pay, and employers may also make matching or discretionary contributions. In the 20250822143401nal0002604179001, both types of contributions may exist—and they are not always fully vested.
This can lead to issues if the QDRO doesn’t differentiate between vested and unvested funds. For example, if the employee has not yet satisfied the vesting schedule, some employer contributions may be forfeited upon termination—and not available to divide.
The solution? A well-drafted QDRO should specify that the alternate payee only receives a share of the vested plan balance as of a particular date (usually the separation or divorce date).
