Employee vs. Employer Contributions
Most 401(k) balances include both:
- Employee Contributions: These are fully vested and typically easier to divide.
- Employer Contributions: These may be subject to a vesting schedule, meaning only a portion is available for division at the time of divorce.
It’s important to review the participant’s vesting percentage with the plan administrator before finalizing division terms. Otherwise, you could award funds that don’t legally belong to the participant—leading to delays or rejection of your QDRO.
