Unless the successive succesor plans all never ever sent out any sort of notice or communication in the over 20 years since Continental Can, I do not see how the OP does not know who is now responsible. As a result I have the questions.
If I assume that the successor plans had no reason to send out any sort of communication to this QDRO beneficiary, I would then have to wonder why there was no monitoring of plan participation,, retirement date etc. which would have kept the OP up to date and informed over the years. I would have thought that it would be in a beneficiary's best interest to keep in touch with the plan since you could say that it is their money.
If I were a QDRO beneficiary I would certainly want to know retirement eligibility, retirement date, expected benefit, how payments will be made by whom etc.
Since the OP has apparently not kept in touch or up to date, I think that it is quite logical to wonder what the OP really knows.
Why do you believe that the plan administrator has been sending out notices?
For the last 25 years US corporations and their subisdaries have been bought and sold like commodities on the world financial markets for tax or or accounting reasons. During the tech boom some telecom companies were sold once a year for several years and often end up being owned by companies located in foreign countries with no knowledge of the requirements of US laws.
When a company is sold the first employees to go are the personnel and HR departments because they are considered to be overhead whose cost can be eliminated without affecting profits. It may be months or years before anyone at the acquiring entity attempts to contact participants or the company may be sold again. Frequently the work of reviewing benefit records and contacting plan participants is outsourced to the lowest bidder who will minimize the amount of work done to fit the budget. Records are shipped off to storage for a few years before they are shredded as a cost savings measure before all benefits are paid. Companies may not send out notices to save on expenses.
Electronic data cannot retrieved be after 5-10 years because no one can access the format used to store the data or because the data has degraded.
Change of address notices sent by participants are frequenetly directed to an address no longer used by the Plan sponsor or acquiror or there are no personnel available to process the change of address.
Plan participants should never leave their retirement money in a former employer's plan if it can be rolled over because they may not be able to locate the plan administrator years later.
