The Real Housewives of Atlanta star Kelli Ferrell's ex-husband, Mark Ferrell, is accusing her of refusing to allow him his visitation with their children, Us Weekly can exclusively report. The Bravo star adamantly denied the claims. On December 9, Mark filed a lawsuit against Kelli, 40, seeking to modify his child support payments and the current custody arrangement. He also asked that the Bravo star be found in contempt of court. Kelli and Mark were married from 2011 to 2022. The exes share three minor kids: Chance Ferrell, born in 2012, and twins Chasiti Ferrell and Chelsi Ferrell, born in 2015. In his complaint, Mark explained that Kelli was awarded primary custody of the kids in the divorce. Mark was granted visitation every other weekend. The exes share joint legal custody. RHOA's Kelli Ferrell Hit With Protective Order for Alleged Harassment During the marriage, Kelli opened a restaurant named Nana's Chicken-N-Waffles. Mark also worked on the business. The RHOA star was awarded all interest in the restaurant in the divorce. Mark said the court improperly calculated his income as $19,847 per month when determining how would pay $3,991 per month in child support. He said his income is $0 since Kelli was awarded the restaurant. "[Mark] has had no income since his business was taken as a part of the divorce," his petition read. Mark asked that his child support obligations be modified since he has no income. His lawyer also claimed Kelli "has refused to allow [Mark] to exercise visitation with his children at all throughout the entirety of the one-year period since the divorce decree was entered." Kelli Ferrell Paras Griffin/Getty Images for Lionsgate Mark's complaint asked that the court grant him more visitation time, "given the excessive amount of time that he has not been able to exercise visitation." His suit also asked the court to strip Kelli of her power to make final decisions regarding their kids, due to her "history and practice of alienation." In addition, he requested that Kelli be found in contempt for refusing to allow him his visitation time. Kelli's rep tells Us, "Kelli finds the claims in her ex's recent filing both surprising and inaccurate. At no point has she prevented him from seeing their children, and she has consistently complied with court orders while prioritizing their best interests."

This has been the case despite the fact that her ex-husband has not paid child support since the divorce." "Kelli is confident the facts will speak for themselves in court," the rep ended. As Us first reported, Kelli filed her own petition against Mark on October 2. She accused him of attempting to interfere with their children shooting scenes for The Real Housewives of Atlanta. RHOA's Kelli Ferrell Calls Police After Neighbor Allegedly Assaults Her "[Mark] has objected, creating confusion and prompting the network to demand judicial clarification before continuing to film the children," Kelli's filing read. Kelli, who hired her RHOA costar Phaedra Parks to represent her in the court battle, alleged that Mark had been making threats of litigation against the network. "As a mother, my children are a significant portion of my storyline. As such, I consented to their participation in The Real Housewives of Atlanta season 17," she wrote in court docs. Kelli asked that the court intervene in the matter. Mark's lawyer Latoya Francis-Williams previously told Us, "And as their father, he has every right to protect their privacy and emotional well-being. Equally concerning is the decision to return this case to the same judge who previously stripped Mr. Ferrell of his home, business, vehicles, and primary income source without due process. Given that an intent to sue [court officials] has already been filed, this raises significant questions about fairness, bias, and judicial propriety."
