[adning id=“43652”]

Khloé Kardashian has undergone a legal name change process for her baby boy with Tristan Thompson. Initially, the birth certificate had the name “Baby Kardashian” as Khloé had not decided on a name at the time. However, according to documents obtained by PEOPLE, they have officially changed his name.

A Los Angeles county judge recently approved the name change for their now 13-month-old son, formally establishing him as Tatum Thompson. This significant decision comes approximately a year after the birth of their child.
