1. Employee and Employer Contributions
In a typical 401(k) plan like the Millennia Professional Services of Illinois, Ltd.. 401(k) Plan, both employee contributions (from paychecks) and employer contributions (matching or profit-sharing) are included. However, employer contributions may be subject to a vesting schedule. If the participant is not fully vested, part of the balance may be forfeited if they leave the company. This affects what the alternate payee can receive under the QDRO.
Make sure the QDRO clarifies whether the award includes only the vested account balance as of the date of division or if it includes future vesting rights.
