Employee and Employer Contributions
Most 401(k) plans consist of employee contributions (what the worker puts in from their paycheck) and employer contributions (such as matching or profit-sharing). A QDRO should spell out whether both types of contributions are divided and how much each party gets.
It’s common for divorcing spouses to split only what was earned during the marriage. That’s why dates of marriage and separation are critical. But not all contributions are fully vested—more on that next.
