Employee and Employer Contributions
401(k) plans typically include both employee contributions (deferred from wages) and employer contributions (such as matching dollars or profit sharing). Your QDRO must indicate whether both types of contributions should be divided—or just the portions contributed during the marriage.
Most courts award the community or marital portion of the account only. That means calculating what was contributed and how much those contributions earned during the shared period. If the employee continued contributing after the spouses separated, that part wouldn’t be included in the division.
