On the Russian theme, here's a report into a woman who suddenly discovered that she was legally dead:
Tatyana was so naïve when she believed she would be soon rehabilitated as living. Indeed, she was alive and still held her passport. However, as she realized later, once dead one can hardly revive. There was hardly an authority that knew how to get out of the unusual situation. Neither the bureau for civil status registration, neither the police or the funeral office agreed to shoulder the responsibility for the absurd incident. The pension service and the fiscal department considered Tatyana Rumyantseva as dead for a rather long period already. That was strange, but according to the records of the passport bureau, the woman was dead and alive at the same time. In April 2003, the housing board officially registered Tatyana was not living in her apartment as she was dead.
