Employee and Employer Contributions
Most 401(k) plans include both employee salary deferrals and employer-matching contributions. While employee contributions are always fully vested, employer contributions may be subject to a vesting schedule. This is especially common in plans offered by business entities like Unknown sponsor.
If your divorce judgment includes a percentage split of the entire account balance, your QDRO must specify whether that applies only to vested amounts or includes unvested employer contributions. Important: any unvested amounts at the time of divorce may be forfeited later and may not be payable to the alternate payee.
