Employee and Employer Contributions
With 401(k) plans, contributions come from both the employee and the employer. During the QDRO process, it’s critical to separate which contributions do or don’t belong to the marital estate. If there’s a pre-marital portion of the account—such as money saved before the marriage—it may need to be excluded from the division.
Employer contributions need special attention. They sometimes come with vesting schedules, described next.
