A Delaware court has dismissed a lawsuit involving members of the Tillman family, who are embroiled in a dispute over the management and financial dealings of their family-owned business, Tillman Enterprises, LLC. The court ruled on September 23, 2026, that the plaintiffs, Joel D. Tillman and his sister Jenny R. Wiley, failed to establish valid claims against their brother Warner B. Tillman and the company's accountant, George Lucas. This ruling has significant implications for family-run businesses and the governance of limited liability companies.
The case, identified as C.A. No. 2025-0475-PAF, centers on allegations that Warner, the company’s sole manager, engaged in unauthorized transactions that violated the company’s operating agreement and breached his fiduciary duties. The court’s decision to dismiss the case means that the plaintiffs will have to seek other avenues for resolving their grievances against their brother and the company.
Background
The dispute involves Tillman Enterprises, LLC, a Delaware limited liability company established by the Tillman family after selling a bottled water business. The company is owned by Warner Tillman and his three siblings: Joel, Jenny, and Joshua Tillman. Warner is the sole manager of the company, and the siblings collectively hold a 20 percent membership interest each.
The plaintiffs, Joel and Jenny, filed their initial complaint in May 2025, claiming that Warner had engaged in a series of unauthorized transactions without the necessary approval from the other members, which they argued violated the company’s operating agreement. They alleged that Warner borrowed large sums from the company for personal use and made loans to other entities he controlled, all without proper consent from the other members.
After the defendants filed motions to dismiss the original complaint, the plaintiffs amended their complaint in August 2025 to include additional allegations against Lucas, the company’s accountant, claiming he aided and abetted Warner’s breaches of duty. The case ultimately reached the Delaware Court of Chancery, where the court was tasked with determining whether the plaintiffs had valid claims against both Warner and Lucas.
The Ruling
The court ruled in favor of the defendants, granting their motions to dismiss the amended complaint. The court found that the plaintiffs did not sufficiently establish personal jurisdiction over Lucas, as they failed to demonstrate that any substantial acts in furtherance of the alleged conspiracy occurred in Delaware.
The court stated, "Plaintiffs concede that they have not alleged a substantial act, or any act, that occurred in Delaware. Instead, they contend that Lucas allegedly aided and abetted Warner’s breaches of fiduciary duty. However, Delaware law forecloses that argument."
Regarding Warner, the court found that the plaintiffs did not present sufficient evidence to support their claims of breach of fiduciary duty and unjust enrichment. The court emphasized that the plaintiffs had to show that Warner acted outside the authority granted to him by the company’s operating agreement, which they failed to do.
Impact
The court's decision sets a significant precedent for family-owned businesses and limited liability companies in Delaware. It underscores the importance of adhering to operating agreements and the need for members to approve major decisions collectively. The ruling also clarifies the standards for establishing personal jurisdiction over defendants in cases involving alleged breaches of fiduciary duty.
This outcome may discourage similar lawsuits within family businesses, as it highlights the challenges plaintiffs face in proving claims against family members who are also business managers. The ruling could also affect how family businesses approach governance and decision-making to avoid disputes in the future.
What's Next
The plaintiffs may consider appealing the court's decision, but details regarding any potential appeal were not available in the court filing. As of now, there are no related cases pending that could impact this ruling.
