1. Traditional vs. Roth Account Balances
Most 401(k) plans now offer both traditional (pre-tax) and Roth (post-tax) sub-accounts. It’s critical that your QDRO specifies how each account is to be divided. If the entire account is split proportionally, the order should make that clear—or, if only the pre-tax portion is being divided, that must be stated unambiguously.
Failing to address Roth balances properly could result in incorrect distributions or tax reporting issues for the alternate payee.
