1. Employee vs. Employer Contributions
Most 401(k) plans include both employee deferrals and employer contributions. The employee’s own contributions are usually fully vested, but employer contributions may be subject to a vesting schedule. The QDRO must clearly state what percentage or dollar amount from each type of contribution is being awarded to the alternate payee (the spouse who is receiving a share).
Be wary of dividing employer contributions that aren’t fully vested. If the employee separates from the company before vesting, unvested amounts may be forfeited, which could lead to complications if the QDRO references a dollar amount that ends up no longer available.
