1. Employee vs. Employer Contributions
The A Little on the Side, LLC 401(k) Plan likely includes both types of contributions. Employee contributions are always fully vested—meaning they belong to the employee regardless of how long they’ve been with the company.
Employer contributions, on the other hand, may be subject to a vesting schedule. This means only a portion (or none) may actually belong to the employee spouse at the time of divorce. The QDRO can only divide vested amounts unless both spouses agree otherwise.
