In the Madoff case his company was put under receivership, not seized: http://www.sec.gov/news/press/2008/2008-293-order.pdf
And ownership wasn't transfered of anything: he was enjoyed from transferring or disposing of value.
Per the document linked to Madoff's estate was put under an "order freezing assets" [1]. Dotcom's property is described as being "seized and restrained" [2], not confiscated or forfeited.
