In December 2020, according to an investigative report by Radio Free Europe / Radio Liberty, it was identified at least $785 million in European and U.S. real estate purchases made by Nazarbaev's family members and their in-laws in six countries over a 20-year span. This figure includes a handful of properties that have since been sold, including multimillion-dollar apartments in the United States bought by Nazarbaev's brother, Bolat. It does not include a sprawling Spanish estate owned by Kulibaev, for which a purchase price could not be found.
