Rumer Willis accused her ex Derek Richard Thomas of “incessant domestic violence” in bombshell court documents fighting for custody of their toddler, Louetta.
Demi Moore and Bruce Willis’ daughter has been engaged in a contentious legal battle with her child’s father since Thomas requested an order for child custody and visitation in July 2025, Us Weekly reported Wednesday.
Rumer responded by detailing a “persistent pattern” of “insane emotional abuse” that took place before their 2024 breakup — “often in front of the minor child or while they were trapped in the car with him.”
The 37-year-old, who has asked for primary physical custody, alleged, “He engaged in ongoing coercive control through prolonged circular verbal attacks that he is unable or unwilling to stop. [He] engages in this type of attack for over six hours at a time on what became a daily basis.”
She wrote that Thomas’ “erratic and bizarre” behavior “escalated” after their daughter’s April 2023 birth.
“I was constantly trying to keep the peace and walk on eggshells,” Rumer claimed. “He wanted to isolate me from my friends and family. He constantly called me a liar with no reason behind it. He told me I was a bad girlfriend all the time.
“He had paranoid behavior saying that my mother and I were plotting to take Louetta away from him,” Rumer added. “He got very mad at me when I would not let his mother smoke weed in my house when Louetta was a newborn.”
She continued, “For a long time, it was difficult for me to stand up to [Thomas] as I tried to avoid his emotional tirades and abuse even for a long time after he moved out.”
Rumer claimed the dynamic left Louetta, now 3, “traumatized” and “crying a lot,” which is why she “does not want [him] to have overnights or time with Louetta without a 730 child custody evaluation.”
Additionally, Rumer expressed hesitation over Thomas’ fiancée, Lizzie Loch, being present for his parenting time “due to his known history of fighting in relationships, and in front of the child.”
Thomas, however, insisted Rumer made this request because she feels “enraged” by their daughter’s “clear affection” for his new partner.
As for the abuse claims, he declared, “I have committed no acts of domestic violence in any form, including any active coercive control. [Our] relationship was unhealthy and appropriately came to an end, but it was not at all characterized by any violence, physical or emotional attacks or intimidation on my part.
“The decision to end the relationship between myself and [Rumer] was a mutual decision made in our mutual best interests,” he continued.
Thomas also fired back at Rumer’s request that he “submit to court-ordered drug testing due to his history of chronic daily marijuana use and evidence of behavior indicative of someone under the influence of drugs for extended periods of time.”
Claiming he is not a “current user of marijuana,” Thomas wrote, “I have previously used marijuana as legally allowed and at no point did I engage in the use of marijuana to such a degree as to render me unable to fully and properly fulfill my duties and obligations as Louetta’s father.”
Rumer, however, described an alleged incident when the exes lived together and Thomas was “so high, that he could not even watch her for those couple of minutes without her rolling off the couch.”
She also accused Thomas of letting Louetta “fall off the bed once in November 2023,” alleging, “He then made it all about him that I was upset about him letting her fall off the bed instead of just comforting her baby and helping her feel better.”
Rumer also requested that Thomas not be allowed to bathe with Louetta, calling this “highly inappropriate … at her age.”
Thomas, meanwhile, insisted, “[Louetta] never suffered for any want in my care, has never been injured in any way, has not suffered trauma or emotional or physical abuse of any kind nor been neglected at any time she’s been in my care. [Rumer] fails to detail, even a single credible instance of any mistreatment or neglect by me.”
Elsewhere in the documents, Rumer accused Thomas’ alleged antics of causing “high stress and chaos” during her visits to Los Angeles to visit her “extremely ill” father, Bruce, who suffers from frontotemporal dementia.
She also claimed Thomas has not paid her “any support” — and expects her “wealthy family to take care of everything,” which she claimed is impossible as she “does not rely on her parents for her expenses to be paid [and is] going to be in severe debt with attorney fees.”
Moore, 63, weighed in on Rumer’s claims in one filing, breaking down Thomas’ allegedly “aggressive” behavior during Louetta’s birth.
The actress alleged, “[He had] no consideration to Rumer, the baby, the process, or anyone else for that matter. He essentially ruined what should’ve been one of the happiest moments of her life.”
Thomas’ lawyer told the outlet Rumer’s filings were “substantially inaccurate and replete with false allegations,” adding, “Derek Thomas is an excellent father who wants nothing more than to be a fully responsible, committed, caring and devoted father to their child.”
Reps for Thomas, Rumer and Moore have yet to respond to Page Six’s requests for comment.
Thomas and Rumer went public with their romance in November 2022, with the latter debuting her baby bump the following month.
Their split news broke in August 2024, with Rumer revealing via Instagram Stories that she was “single-moming it.”
The duo reached a temporary custody agreement in August 2025, per Us Weekly, which allowed Thomas six hours per day for up to three to four days per week in Los Angeles or Sun Valley, Idaho.
They participated in mediation with a private judge the following month.
After squabbling over jurisdiction for the custody case — Rumer called Idaho Louetta’s “home,” while Thomas claimed Rumer relocated there without his permission — a judge dubbed California the correct venue in January.
Rumer broke her silence on the breakup in an “Inside Edit” podcast interview last week, claiming the relationship had been “brutal and challenging.”
