Employee vs. Employer Contributions
In many 401(k) plans, there are two primary types of contributions—those the employee defers from their paycheck and those the employer contributes as a match or discretionary amount. Employer contributions often come with a vesting schedule, meaning the employee earns the right to keep them over time (usually based on years of service).
The QDRO must clarify whether the alternate payee’s share includes only vested amounts or a percentage of all contributions (even those forfeited later). It’s critical to specify the valuation date clearly, especially for unvested employer contributions.
