Tristan Thompson is taking another legal step to secure long-term care for his younger brother, filing for conservatorship over 19-year-old Amari Thompson. According to court documents obtained by Page Six, the NBA veteran is seeking to become Amari’s limited conservator, citing his brother’s inability to manage basic personal needs and finances due to a developmental disability.
The filing outlines the extent of Amari’s condition, stating he is “unable to properly provide for his personal needs for physical health, food, clothing or shelter,” and cannot manage financial decisions or protect himself from “fraud or undue influence.”
The documents also note that Amari is not in a position to weigh in on the conservatorship due to his intellectual disability and developmental delays.
Amari lives with Lennox-Gastaut syndrome, a severe form of epilepsy that can cause frequent seizures and long-term cognitive impairment. The condition has been part of the Thompson family’s public story for years, with Tristan previously launching the Amari Thompson Fund to support epilepsy awareness through Epilepsy Toronto.
This latest filing builds on a legal shift that began in 2024, when Tristan became Amari’s official guardian following the death of their mother, Andrea Thompson.
At the time, a judge determined that their father’s involvement was “not viable due to neglect, abandonment under California law,” effectively placing full responsibility on Tristan.
The move toward conservatorship now formalizes control over broader aspects of Amari’s care, including financial and medical decisions.
Public insight into Amari’s daily life has also come through Khloé Kardashian, Tristan’s ex-girlfriend, who has played a hands-on role in his care. Speaking on her podcast, she described the reality of his condition: “He is severely disabled… He can’t walk or talk,” adding that he experiences “a handful of seizures a day.”
Due to Tristan’s travel schedule, Amari often stays in Los Angeles with Kardashian, who has arranged consistent caregiving support and stability.
