Employee vs. Employer Contributions
In most 401(k) plans, contributions are made by both the employee and the employer. Employee contributions are always 100% vested, but employer contributions aren’t guaranteed—some may still be subject to the company’s vesting schedule. That means your former spouse may not yet own all the funds in their account.
In a QDRO for the Diversified Well Logging, LLC 401(k) Plan, it’s critical to separate vested and unvested amounts and request division of only what the participant is entitled to at the time of distribution (unless local law or agreement says otherwise).
