Vesting Schedules and Unvested Contributions
401(k) plans often come with a vesting schedule for employer contributions. If the employee hasn’t reached full vesting at the time of divorce, some of the employer match may be excluded from the marital estate. Most plans will only allow the QDRO to divide what the participant is vested in on the date of division—nothing more.
Make sure your QDRO clearly states whether the division applies only to vested balances. If this detail is missed, the plan administrator may default to their rules and ignore intentions for a fair division.
