1. Employer Contributions and Vesting Schedules
Most 401(k) plans include both employee salary deferrals and employer contributions (through matching or profit sharing). These employer contributions are often subject to a vesting schedule—meaning your spouse might not yet have ownership of the full amount. A proper QDRO accounts for this. You can’t divide what the participant doesn’t own yet unless the plan explicitly permits “future vesting” for alternate payees—which most do not.
