1. Understanding 401(k) Contributions: Employee vs. Employer
The Trillium Engineering 401(k) Plan likely includes both voluntary employee contributions and employer matching. These two sources must be considered separately in any division.
- Employee Contributions: These are fully vested immediately and can generally be divided as of a specific date or percentage.
- Employer Contributions: May be subject to a vesting schedule. Any unvested amounts will most likely be forfeited if the employee leaves before meeting certain service requirements.
The QDRO must specify whether only vested balances are to be divided, and how to handle future vesting or forfeitures after the divorce.
