Employee vs. Employer Contributions
Employee contributions are always 100% vested and belong to the participant, so they can be divided easily. However, employer matching contributions are often subject to a vesting schedule. That means if the participant hasn’t worked at the company long enough, some of these contributions may not be available to divide—or may later be forfeited.
The QDRO must specify whether the alternate payee (the spouse receiving a share) is entitled to only vested balances at the time of the divorce or to future vesting, depending on how your settlement reads.
