Christine Brown is taking legal action against her ex-husband Kody Brown.

Just nearly three years after ending her marriage with Kody, 55, in November 2021, Christine, 52, has reportedly filed a lawsuit against

the Sister Wives patriarch.

According to the court documents obtained by In Touch, Christine is suing Kody for child support and custody of their 14-year-old daughter, Truely Brown.

Christine is said to have filed the legal paperwork on Monday, Sept. 16, formally requesting the court to establish paternity of her youngest daughter since Kody isn’t listed on Truely’s birth certificate.

Additionally, Christine requested a domestic relations injunction that would stop both parties from harassment, domestic violence, demeaning or disparaging the other party, canceling or modifying services and taking the child for “nonroutine travel” without court orders or permission, In Touch reports.

Since her parents separated, Truely has been living with her mom in Murray, Utah after Christine sold her home in Flagstaff, Ariz in October 2021. Kody and Christine officially announced their separation via Instagram the following month.

Christine was spiritually married to Kody for over 25 years, meaning their marriage was recognized by the church but not the state. Throughout their 25 years of plural marriage, they welcomed six children together: Aspyn, 29, Mykelti, 28, Paedon, 26, Gwendlyn, 22, Ysabel, 21 and Truely.

Christine’s decision to leave the polygamous marriage marked the first of three splits for Kody over the next two years. Janelle Brown later confirmed her separation from Kody in December 2022, followed shortly by Meri Brown announcing her split from Kody in January 2023.

Kody, a father to 18, is still married to wife Robyn Brown, with whom he shares five children. He also shares six kids with Janelle and one with Meri.

Christine has since moved on with new partner David Woolley, whom she wed in October 2023.
