Employee and Employer Contributions
In a 401(k) plan, contributions typically come from both the employee and often their employer. The QDRO can be drafted to divide only the employee’s contributions, or it can include employer-matching contributions as well—depending on what was earned and vested during the marriage.
It’s common to split only the portion earned during the marriage, on a date-of-marriage to date-of-separation basis. Make sure your QDRO specifies this clearly.
