1. Employee vs. Employer Contributions
401(k) plans often contain two types of contributions: those made by the employee and those made by the employer. The QDRO can specify whether the division should apply to:
- All contributions (both employee and employer)
- Only the employee’s contributions
- Only marital contributions—those made during the marriage
Accurately determining what portion is marital is critical, especially when the participant started or ended participation in the plan outside the marriage timeframe.
