Under California law, parents have the liberty to choose the surname for their child upon birth. In this case, Khloé Kardashian, aged 39, and Tristan Thompson, aged 32, initially filed paperwork earlier in the year to change their son's last name from Kardashian to Thompson. The court approved this change, finalizing their decision to officially name him Tatum Thompson.
This legal alteration marks a significant step in the life of the now 13-month-old Tatum, who was originally listed as 'Baby Kardashian' on his birth certificate. The couple's journey to this decision was not without its share of challenges, including a tumultuous period in their relationship.
