Employee and Employer Contributions
401(k) plans typically include both employee deferrals and employer matching contributions. Unless the couple agrees otherwise, a QDRO generally divides only the marital share—usually the portion contributed and accrued during the marriage. However, separating out the amount attributable to employee contributions versus employer match can matter, especially when the employer match isn’t fully vested.
Your QDRO should clearly state how to divide contributions and specify whether both employee and employer portions are split. Otherwise, the alternate payee (the non-employee spouse) might either receive too much or too little.
