Employee vs. Employer Contributions
QDROs typically apply to the full 401(k) account unless limited otherwise. This includes both employee deferrals and employer contributions. However, many 401(k) plans only vest employer contributions over a period of time. If the participant spouse isn’t fully vested, part of the employer contributions may not be divisible through a QDRO.
It’s crucial to determine vesting status as of the division date. Otherwise, you may end up awarding more than what’s actually available to the alternate payee (the spouse receiving part of the retirement).
