Employee and Employer Contributions
In a 401(k) plan, the employee (participant) can make elective salary deferral contributions, and the employer may offer matching or non-matching contributions. In this case, the plan offered through Genomatica, Inc.. is likely structured with both components, given its status as a corporate-sponsored benefit in the general business sector.
During divorce, both the employee’s contributions and the employer’s vested contributions are typically subject to division. Unvested contributions may not be divided unless they later vest under the plan’s schedule—and that should be clearly addressed in the QDRO.
