Employee vs. Employer Contributions
A QDRO can divide all or part of a participant’s balance, but there’s an important distinction between what the employee contributed and what the employer provided. Employer contributions may be subject to a vesting schedule. If a participant is not 100% vested, some of those contributions will be forfeited—meaning they cannot be awarded to the alternate payee.
In your QDRO, clarify whether the award is based on the total account balance or only the vested portion. If you’re dividing the full account, make sure the QDRO reflects whether any unvested employer contributions should be excluded.
