1. Understanding Contribution Sources
In 401(k) plans, the account balance often includes both:
- Employee Deferrals: Money the participant (employee) voluntarily contributed.
- Employer Contributions: Matches or profit-sharing contributions made by the company.
Your QDRO should specify whether both sources are included in the division. If the document merely says “account balance,” the plan may default to including only employee deferrals. That can be a costly mistake if the employer’s contributions are substantial.
