Employee and Employer Contributions
The account value of a 401(k) typically includes both employee contributions (what the participant put in) and employer contributions (matches or profit-sharing). Not all employer contributions may be fully vested, which could affect what’s actually available to divide.
If employer contributions are not fully vested at the time of divorce, those unvested amounts may not be payable to either spouse. Your QDRO must clearly define what portion—vested only or total balance—will be distributed to the alternate payee.
