Employee vs. Employer Contributions
401(k) accounts often include contributions from both the employee (money the participant contributes from their paycheck) and the employer (such as matching funds). These may not be fully vested at the time of divorce. It’s important that the QDRO clearly identifies whether you’re dividing only the vested portion or including a share of future vesting.
If the participant’s employer contributions haven’t vested yet, they may be forfeited later and cannot be divided. If the goal of the divorce agreement is to divide the full account—including unvested funds—timing and vesting schedules must be considered.
