Employee vs. Employer Contributions
A QDRO can divide both employee and employer contributions. However, only vested portions of employer contributions are available for division. If the participant isn’t fully vested, some of the employer match may still be forfeitable—ex-spouses can’t receive a share of this unvested amount.
It’s critical your QDRO defines the division clearly—whether by percentage (e.g., 50%) or a flat dollar amount—and whether gains/losses will apply from the division date.
