Employee vs. Employer Contributions
Most 401(k) plans include both employee contributions (money the employee elects to defer from their paycheck) and employer contributions (matching or discretionary amounts from the company). The QDRO should specify how both sets of contributions are divided.
If you’re dividing the account by a percentage of the full balance, be sure the QDRO specifies whether that includes employer contributions. In some cases, only employee contributions may be vested — meaning the employee actually owns them.
