401(k) Basics: Employee Contributions vs. Employer Contributions
Employee contributions are always 100% vested, which means they belong entirely to the employee—even in divorce. Employer contributions, however, are often subject to vesting schedules. That matters because any unvested funds at the time of divorce may not be available for division.
If the plan participant is still working for the employer (which, in this case, is listed as Unknown sponsor ), any future vesting or forfeiture of employer contributions must be addressed in the QDRO. It’s critical to clarify whether the alternate payee will share in future vesting or only what’s vested as of the date of divorce.
