Dividing Employee and Employer Contributions
401(k)s generally include both employee contributions (deferrals taken from paychecks) and employer matching or profit-sharing contributions. In your divorce, both of these may be subject to division, but there’s a catch—the vesting schedule.
Some employer contributions aren’t fully owned by the employee until a certain number of years of service. That’s where a QDRO must be carefully worded. If your spouse isn’t 100% vested at the time of division, the order should avoid awarding benefits that your spouse doesn’t yet “own.”
