Mia's filing listed a Dallas residence, which suggests that although Married at First Sight's recent episodes have shown the pair discussing a possible move to Houston, TX, they either never moved or subsequently relocated back to Dallas.
Judge David Lopez is the judge currently assigned to the divorce case, which has yet to proceed beyond the initial filing of the divorce petition.
While Married at First Sight's seventh season only premiered on Lifetime in July, Mia and Tristan tied the knot without knowing anything about each other in late March 2018. They exchanged vows on-camera after meeting each other for the first time at the altar.
The timing of the divorce filing would seem to indicate Mia and Tristan chose to stay together and remain married on "Decision Day," which was filmed in late May at the conclusion of Married at First Sight's extreme eight-week experiment.
However, the couple may also have opted to split at the end of Married at First Sight's filming and simply waited three months to get around to formally filing for divorce.
Mia, a 29-year-old airline recruiter; and Tristan, a 29-year-old former collegiate and semi-pro basketball player, have been shown dealing with many ups and downs in their relationship on Married at First Sight.
The biggest hurdle the couple had to overcome was Mia initially lying to Tristan about her March 27 arrest in which she had been detained in a Texas airport while traveling to Cancun, Mexico for their honeymoon and spent two days in custody.

An arrest warrant had been issued back in February by Mia's alleged ex-boyfriend, Jared Evans, who claimed she had stalked him on multiple occasions in the 13 months that followed their December 2016 breakup and also made an unauthorized purchase of an Apple iPhone on his credit card one year after their split.
Mia initially told Tristan the situation was a matter of identity theft and she had no relationship with her accuser, but she slowly came clean to her concerned husband off-camera, resulting in a lack of trust in their marriage.
After footage of Mia's arrest aired in July, Married at First Sight's producers had released a statement insisting all necessary precautions were taken during casting and viewers would have a front-row seat as drama unfolded between the couple "in real time."
"On this season of Married at First Sight, one of this season's participants, Mia, was detained at the airport by authorities as she was about to leave on her honeymoon with her new husband, Tristan," a MAFS representative toldPeople.
"The warrant for Mia's arrest was filed after her background check had been cleared by production."
"Viewers will have the opportunity to watch their emotionally true story as it unfolds in real time throughout the season and learn whether or not the couple ultimately decides to stay married or get a divorce."
As of the latest September 11 episode of Married at First Sight, however, Tristan and Mia's romance is doing quite well and they are falling in love with each other more and more every day.
