Vesting Schedules and Forfeitures
Many employer contributions within a 401(k) are subject to a vesting schedule. If the employee spouse (called the participant) hasn’t worked long enough to be vested in some or all of the employer’s contributions, those amounts may be forfeited if they leave the company. A strong QDRO will specify whether the alternate payee is entitled to only the vested balance or a percentage of the entire account—including unvested amounts as they vest in the future.
