Employee vs. Employer Contributions
401(k) accounts generally include both employee salary deferrals and employer matching contributions. Only vested employer contributions can be divided in a QDRO. If unvested contributions exist, they do not become part of the marital property unless they vest before the QDRO is approved.
That’s why reviewing the participant’s vesting schedule is critical. If the participant is close to full vesting, it may be worth waiting until that point before submitting the QDRO to ensure a larger marital share.
