My 20 year old son just got a shareholder notice to vote in the 2025 proxy meeting for Liberty Mutual Holding Corp. He does not own stock in Lib. I don't own stock in Lib. The family doesn't own stock in Lib. Either it was a mistake or somebody has purchased stock in his name accidentally or fraudulently in his name. Not sure if an ID theft product is my best bet but I thought I would try here first. How do I find his account and either correct it or seize it.
