A couple who had divorced and obtained a QDRO dividing the husband's retirement plan account decide to remarry.
The wife's share of the husband's account was segregated within the plan but never transferred out of the plan.
My understanding is that it is possible to get a court order declaring a QDRO null and void, but that un-segregating the segregated account may constitute a breach of fiduciary duty under ERISA. Does anyone know of legal authority to this effect?
