Traditional vs. Roth Subaccounts
Many modern 401(k) plans include both traditional and Roth subaccounts. The traditional account grows tax-deferred, while Roth contributions are made after-tax and grow tax-free. If the participant has both account types, your QDRO must specify whether the alternate payee (usually the ex-spouse) is receiving a share from the traditional account, the Roth account, or both.
Getting this wrong can create serious tax issues, so precise drafting matters.
