Vesting and Employer Contributions
Many 401(k) plans have complex vesting schedules for employer contributions. This means that while an employee’s own contributions are always 100% theirs, the employer match may only partially belong to them based on years of service.
If you’re the alternate payee (the spouse receiving a share), it’s critical to confirm what portion of the employer match is actually vested. You can only be awarded vested benefits under a QDRO. Any unvested amounts usually revert back to the plan once the employee leaves the company.
