1. Employee and Employer Contributions
This plan likely includes both employee contributions (money the participant deferred from their paycheck) and employer matching or discretionary contributions. Those employer contributions may be subject to a vesting schedule—which means not all balances are owned by the participant unless the vesting requirements are met.
When creating a QDRO, you must be careful to define whether the division includes only vested amounts or will account for a future vesting schedule.
