Rumer Willis and Derek Richard Thomas’ romantic relationship has taken a tumultuous turn. Following their split, which was described as “brutal,” new details have emerged about their ongoing legal disputes regarding child custody and visitation.

Timeline of Rumer Willis and Derek Thomas’ Relationship
- 2022: Willis and Thomas start dating.
- 2023: Their daughter Louetta is born.
- 2024: The couple separates, with Willis publicly stating she is “single-moming it.”
- July 2025: Thomas files legal petitions to establish custody.
Legal Disputes and Allegations
Their split has been marked by significant legal battles, with allegations of emotional abuse and drug use surfacing. According to court documents from January 2026, Thomas has claimed he wants joint legal and physical custody of their daughter. He asserted that Willis’ move to Sun Valley, Idaho, with Louetta was made without his consent.
Willis, however, contended that Thomas’s claims about co-parenting are unfounded. In her declaration, she stated that their daughter has been affected by Thomas’s behavior during their relationship. She described the environment during Louetta’s first months as traumatic, stating that Thomas engaged in emotional abuse.
Child Custody Arrangements
The custody arrangements have sparked consistent conflict. Thomas sees Louetta approximately once a month, but Willis alleged that he refuses multiple offers for visitation in Idaho. Additionally, she requested that a “730 evaluation” be conducted, which involves a professional assessment of the family’s situation to inform custody decisions.
Willis’s Claims Against Thomas
Willis accused Thomas of exhibiting unstable behavior, citing incidents where he reportedly endangered their child. She raised concerns about his drug use and described instances of emotional abuse that allegedly occurred in front of Louetta. In her claims, she emphasized that she does not engage in substance use and expressed worries about Louetta’s well-being while in Thomas’s care.
Financial Strain and Support Issues
The financial implications of co-parenting have also been contentious. Willis has stated she incurs significant monthly expenses for childcare and has indicated that Thomas has not contributed to their child’s financial needs. According to her documents, he has made no offers to support Louetta’s medical or personal expenses.
Conversely, Thomas has claimed to be a dedicated father and insists that his alleged financial shortcomings are exaggerated. He has questioned Willis’ portrayal of their relationship dynamics, asserting he has always supported Louetta’s needs.
Demi Moore’s Involvement
Demi Moore has provided testimony regarding Thomas’s behavior during Rumer’s home birth, indicating he showed a lack of sensitivity towards the situation. Moore stated that Thomas attempted to dominate the environment during the birthing process and sought to undermine the family’s support for Rumer.
Conclusion
The fallout from Rumer Willis and Derek Thomas’s breakup continues to unfold amid serious allegations concerning their parenting arrangements and personal conduct. As both sides prepare for court proceedings, the outcome will likely hinge on the court’s evaluation of their claims regarding custody and the welfare of Louetta.
