Employer Contributions and Vesting
In most 401(k) plans, the employer may contribute matching or discretionary amounts. However, those amounts are usually subject to vesting. That means if the divorce takes place before the full vesting period ends, some employer contributions may be forfeited.
Your QDRO should clearly state that only vested account balances are to be divided—and must specify the “date of division” carefully as that will determine the vesting snapshot.
