Partnership & Shareholder Disputes When the Result Means Everything™

Partnership & Shareholder Dispute Lawyers in Dallas

Partnership & Shareholder Litigation

Many businesses are owned by more than one person. Even privately owned businesses can be owned or managed by dozens, hundreds, or even thousands of people. Naturally, disagreements arise in connection with the operation of a business; however, allegations of oppressive or unlawful conduct can lead to bitter litigation between owners, partners, or shareholders—putting the future, expansion, control, or even dissolution of a business into question.

These disputes arise in corporations, limited liability companies, and partnerships of all kinds. Typically, partners and shareholders owe certain fiduciary duties to the business itself—and in some circumstances, to each other. These cases vary based not only on the type of entity involved, but the terms and conditions contained in organizational documents, such as an entity’s Company Agreement or Articles of Incorporation. Disputes can involve claims of misappropriation of trade secrets, profit distributions, business mismanagement, self-dealing, fraud, breaches of contract, or shareholder oppression.

Justice Served:

Record Verdicts Achieved
  • For their successful pursuit of justice in the face of adversity, Lyons & Simmons attorneys Michael Lyons, Chris Simmons, Chris Carr, and Stephen Higdon have been awarded the Dallas Trial Lawyers Association’s prestigious 2021 John Howie Award. The honor is based on the trial team’s work representing an Alabama mother who lost three children in a tragic West Texas highway accident.
  • In a case that drew national attention, Lyons & Simmons attorneys Michael Lyons, Chris Simmons, Chris Carr, P. Wes Black, and Michael Wozniak won a record-setting $109.5 million verdict against CPS Energy after proving the company’s failure to maintain its gas system led to a devastating explosion and fire. The result not only delivered justice for the victims — it set a new standard for accountability in the utility industry.

  • The firm secured a landmark jury verdict for a client whose life was permanently changed after systemic hospital failures caused a nearly five-hour delay in emergency surgery, resulting in catastrophic paralysis. The case brought to light serious breaches of hospital policy and was recognized by Courtroom View Network as one of the nation’s top verdicts of 2022.
