Dividing Employee vs. Employer Contributions
A 401(k) plan like the Marine Biological Laboratory Defined Contribution Retirement Plan typically includes both:
- Employee salary deferrals (contributed directly from the participant’s paycheck)
- Employer contributions (matching or discretionary)
If your divorce agreement says you’re dividing half the account, make sure that includes both portions. But some agreements only divide the employee contributions. If the participant has a large match balance, this can significantly impact the outcome.
