Employer Contributions and Vesting
Many 401(k) plans include both employee and employer contributions, but not all employer money belongs to the employee right away. That’s where vesting comes in. Until fully vested, an employee only owns a portion of the employer’s contributions.
A QDRO must account for vesting by dividing only the participant’s vested balance. If the QDRO mistakenly awards unvested amounts, the alternate payee (you or your ex-spouse) may end up getting less than expected.
