What are the rules for subpoena of personal records, my wife has been divorced for 5 years and all of a sudden her ex husbands attorney has frozen her 401 k by subpoena under the guise of preparing a QDRO that was never ordered by the court. The original QDRO was filed and accepted by the court in 2003. We were never notified of this action nor is it listed on the court doc list available online to us. Is this possible and how do we combat this we live in Nevada
