1. Employee vs. Employer Contributions
A 401(k) typically includes both employee contributions (directly withheld from a participant’s salary) and employer contributions (such as matching funds). In a divorce, both can be subject to division—but employer contributions might be subject to a vesting schedule.
That means a QDRO might only divide the vested portion as of the date of divorce or another agreed-upon date. If employer matching funds aren’t fully vested, they won’t be available for division—unless you wait for future vesting, which must be clearly stated in the QDRO.
