1. Employer Contributions and Vesting Schedules
401(k) plans often include both employee and employer contributions. While the employee’s contributions (and their growth) are immediately vested, employer contributions may be subject to a vesting schedule—commonly 3 to 6 years. That means only a portion of those funds may be considered “marital” and available to divide unless fully vested before the date of divorce.
If the Participant (the spouse with the 401(k)) is not fully vested, your QDRO should clearly state whether the Alternate Payee (the non-employee spouse) receives only vested funds or a share of future vested funds too. This is a major point of contention in many cases and requires clarity.
