1. Contribution Types: Employee vs. Employer
In a 401(k), the account typically includes:
- Employee Contributions: Always 100% vested and eligible for division.
- Employer Contributions: Subject to vesting schedules. Only vested amounts can be assigned in a QDRO.
Unvested employer contributions may eventually be forfeited if the employee terminates or fails to meet service requirements. It’s vital to account only for vested funds as of the date of division or another chosen valuation date.
