Employee vs. Employer Contributions
401(k) plans typically consist of two types of contributions: those made by the employee (the plan participant) and those made by the employer. In the A.g. Van Metre Services, Inc.. 401(k) Retirement Plan, both types may be present. The QDRO must specify how each type of contribution is to be divided — and whether unvested employer contributions are included.
Generally, contributions made during the marriage are considered marital property. However, employer contributions are often subject to a vesting schedule, meaning they may not fully belong to the employee-spouse at the time of divorce.
