The Superior Court of California, County of Los Angeles, has granted Tristan Thompson temporary guardianship of his 17-year-old brother, Amari.
The ruling grants Thompson, 32, “all powers a parent having legal custody of a child would have,” according to court documents obtained by PEOPLE.
The NBA player’s request for guardianship follows the death of their mother, Andrea, who died in January 2023.
The younger Thompson brother has epilepsy, in addition to other medical conditions that require around-the-clock support, which led Thompson to request guardianship.
The NBA free agent was also granted the authority to “manage ward’s finances and assets, travel with the ward within the United States of America and internationally, enroll ward in social and other extracurricular activities, decide living arrangements of the ward [and] obtain legal counsel on behalf of the ward,” per the official court documents.
This decision follows the court declaring there was both “sufficient evidence” and “good cause” for Thompson to temporarily take guardianship over Amari.
Prior to the court’s decision, Thompson requested sole legal guardianship of Amari on September 8.
In court documents obtained by PEOPLE, Thompson claimed their father, Trevor Thompson, has been absent from his younger brother’s life since 2014. The father of four also claimed he was Amari’s closest living family member.
Thompson also told the court he would like to assist his brother in managing and investing their mother’s inheritance.
