Employee vs. Employer Contributions
Most 401(k) plans include:
- Employee contributions—always 100% vested
- Employer contributions—often subject to a vesting schedule
The QDRO should clearly separate the vested and nonvested portions. Unvested employer contributions aren’t typically divided, and if the employee leaves the company before full vesting, those funds may be forfeited altogether. That’s why it’s essential to pin down each portion of the account at the time of divorce.
