1. Division of Employee vs. Employer Contributions
Most 401(k)s include both:
- Employee contributions – fully owned by the participant once deposited.
- Employer contributions – may be subject to a vesting schedule.
In a QDRO, you’ll need to specify whether both are being divided. Be mindful of unvested employer contributions—they may not be available to divide. If the participant leaves the company, any unvested portion is usually forfeited.
