Employee vs. Employer Contributions
Employee contributions (typically what the participant puts in from their paycheck) are usually 100% vested. Employer contributions, or “profit sharing” deposits from the company, may be subject to a vesting schedule.
If the participant hasn’t worked at Unknown sponsor long enough, some of that employer money may not be fully vested. That means part of the balance could be forfeited and not available to divide. A thorough QDRO will define whether the division applies to just the vested portion or includes future vesting events.
