Employee vs. Employer Contributions
The first step in any division is being clear about whose contributions are being divided. 401(k) plans typically involve both employee elective deferrals and employer contributions. The QDRO should specify whether:
- Only contributions made during the marriage will be divided
- Both employee deferrals and employer matching contributions are included
- Only vested employer contributions will be shared (often the default)
It’s critical to understand what portion of employer contributions has vested—this can drastically change the size of the alternate payee’s award.
