Employee and Employer Contributions
401(k) plans include the employee’s contributions (deferrals from paychecks) and often include employer contributions (e.g., matching). These amounts aren’t always treated equally in a QDRO. The employee contributions are always 100% vested, but employer contributions may be subject to a vesting schedule.
If the order assigns “50% of the total account” without considering vesting, the alternate payee could end up with more or less than intended. In many cases, it’s smarter to specify an award based on the vested account value as of a certain date—often the date of separation or divorce judgment.
