Employee vs. Employer Contributions
Most 401(k) plans consist of two primary sources of money: amounts the employee personally contributed and matching contributions or other contributions made by the employer. A QDRO can divide both types, but there’s a key point to consider—employer contributions may be subject to a vesting schedule.
So even if the total account balance is $100,000, only a portion may be “vested” and available to be divided. Unvested amounts may be forfeited if the employee leaves the company, and that can significantly impact the division of assets in the QDRO.
