Tristan Thompson has filed for conservatorship for his younger brother Amari.
The 35-year-old NBA athlete filed for Amari’s limited guardianship on Monday, according to documents obtained by Page Six.
The document says 19-year-old Amari is “unable to adequately meet personal needs such as physical health, food, clothing, and shelter” and “suffers from intellectual disability and developmental delay.”
The documents also say Mr. Amari is “incapable of managing financial resources and resisting fraud and undue influence.”
Amari said in a written statement that he could not comment on the selection of a guardian “due to his developmental delay and intellectual disability.”
According to the Cleveland Clinic, Amari has LGS (Lennox-Gastaut syndrome), a severe form of childhood epilepsy that can cause multiple types of seizures, cause permanent brain damage, and lead to learning disabilities and other disabilities.
In February 2024, Tristan became Amari’s legal guardian following the death of her mother, Andrea. Amari was 17 years old at the time.
In documents obtained by Page Six, Tristan claimed that his father, Trevor, had no role in raising Amari since 2014.
A judge ruled at the time that reuniting Amari and Trevor was “impossible due to neglect and abandonment under California law.”
Amari appeared on Keeping Up with the Kardashians when Tristan’s former caretaker, Khloe Kardashian, became Tristan’s primary caretaker in July 2025.
“He’s severely disabled. … He can’t walk or talk,” she said on the “Chloe in Wonderland” podcast.
Khloe explained that she decided to keep Amari in Los Angeles due to Tristan’s busy travel schedule with the NBA.
“Amari has the same type of epilepsy and has seizures several times a day,” she said. “It’s not good for him to travel, so I decided to take care of him and be by his side.”
“The weather in California has been great for Amari, and we are so happy to have her as part of our family,” she added.
The mother of two also said it was “important” for her children with Tristan (daughter True, 8, and son Tatum, 3), their children, nieces, and nephews to have Amari around, giving them exposure to different types of people.
“I think this movie teaches compassion and understanding to everyone,” she explained. “It opens their minds and realizes, ‘Wow, Amari is indeed disabled, but he’s also just like us.'”
“We just want to give Amari the best, most beautiful life we know, and he deserves that,” she added, sharing that they hired two caregivers for Amari.
