In August 2013, Aisultan was married to Alima Nazarbayeva. He had a daughter named Ameli (born 2016) and son named Sultan. Aisultan once spent time in a clinic due to alleged cocaine use. It is unknown whether this treatment was voluntary or forced. In October 2019, he was sentenced to a suspended sentence for an attack on a police officer in London in June 2019 and damage to a stranger's property. The verdict included probation, medical treatment, community service, and a fine. On 23 January 2020, Aisultan made a public statement on his Facebook page, claiming that his grandfather Nazarbayev was allegedly his father and that his life was threatened. He also stated that from 8 July 2019, he had not been able to use any of his social media accounts, because he was kept in custody and that the accounts were under control by his mother
Dariga Nazarbayeva and the ex-chairman of the
NSC Alnur Mussayev. In response to those claims, Mussayev on his Facebook page published an unsubstantiated document from 2013 indicating a DNA match of over 99% between Aisultan and his father
Rakhat Aliyev. However, following the death of Aisultan, Mussayev admitted to falsifying DNA records in his interview to
Exclusive Kazakhstan and that Aliyev was indeed not the biological father, yet failed to name the true paternal identity. On 13 February 2020, Aisultan requested political asylum in the United Kingdom. He explained this decision due to pressure by his family, claiming to possess information "about high-scale corruption between the government [sic] of Russia and Kazakhstan". He stated that he did not inherit his father's wealth because his father's wealth was stolen by his mother
Dariga Nazarbayeva and
Alnur Mussayev (or Musaev []) and that he was afraid that both of them wanted him killed. Minister of Information and Social Development
Dauren Abaev reported to
Khabar Agency that "to speculate on the fantasies of an addict just because he is the grandson of the First President, it’s not fair. It’s unfair and beyond morality. It is time to close this topic." ==Death==
