Employee and Employer Contributions
When dividing a 401(k) like the Masco Corporation 401(k) Plan, it’s essential to clarify whether the order will divide only employee contributions or include employer-matching contributions as well. In most cases, the total vested account balance—including both participant and employer contributions—can be divided. However, anything unvested may not be subject to division depending on plan rules at the time of divorce.
For example, if your spouse has a $200,000 balance in their account, but $50,000 is unvested employer money due to vesting schedules, only the $150,000 may be eligible for division.
