Tristan Thompson files for conservatorship over 19-year-old brother Amari

Tristan Thompson has filed for conservatorship over his younger brother Amari.

The NBA athlete, 35, filed to be Amari’s limited conservator on Monday, in documents obtained by Page Six. Per the docs, Amari, 19, is “unable to properly provide for his personal needs for physical health, food, clothing or shelter,” and “suffers from an intellectual disability and developmental delay.”

The docs also note Amari is “unable to manage his financial resources or to resist fraud or undue influence.”

Amari, the docs state, is unable to comment on the selection of a conservator “due to his developmental delay and intellectual disability.”

Amari has LGS [Lennox-Gastaut syndrome], a severe form of childhood epilepsy that causes multiple types of seizures that can lead to permanent brain damage, resulting in learning difficulties and other disabilities, according to the Cleveland Clinic.

In February 2024, Tristan became Amari’s legal guardian following the death of their mother, Andrea. At the time, Amari was 17 years old.

Tristan claimed their father, Trevor, played no role in raising Amari since 2014, in docs obtained by Page Six..

The judge ruled at the time that a reunion between Amari and Trevor was “not viable due to neglect, abandonment under California law.”

Amari has appeared on “Keeping Up With the Kardashians” due to Tristan’s relationship with his ex Khloé Kardashian. Khloé spoke about becoming Amari’s primary caretaker in July 2025.

“He is severely disabled. … He can’t walk or talk,” she said on her “Khloé in Wonder Land” podcast.

Khloé explained that due to Tristan’s busy travel schedule in the NBA, she decided to keep Amari with her in Los Angeles.

“Amari has a handful of seizures a day with the type of epilepsy that he has,” she shared. “I have chosen to take care of him and be there for him because it’s not good that he travels.”

“California weather is so good for Amari and I just love having Amari be a part of my family,” she added.

The mother of two also noted that having Amari around is “important” for her children with Tristan — daughter True, 8, and son Tatum, 3 — as well as her kids, nieces and nephews, so that they can be exposed to all different types of people in the world.

“I think it teaches everyone compassion, understanding,” she explained. “It opens up their minds to seeing, ‘Wow, Amari is disabled, sure, but he’s also just like us at the same time.’”

“We just want to provide Amari with the best, most beautiful life that we know how. And he deserves that,” she added, sharing that she hired two caregivers for Amari.
