Los Angeles Business Litigation Attorneys

Protecting California Businesses at Moore Ruddell LLP

In business, disputes are not a question of if, but when. A contract that one party reads differently from another. A partner who walks away with the customer list. A vendor who delivers half of what was promised – and bills for all of it. When those disagreements cannot be resolved at the negotiating table, the stakes climb quickly. Cash flow, key relationships, intellectual property, and the reputation a business has spent years building can all hang on how the matter is handled in court.

At Moore Ruddell LLP, our Los Angeles business litigation attorneys represent California companies and the individuals who own and run them through every stage of commercial disputes – from the first demand letter to verdict and, where necessary, appeal. We understand that litigation is rarely an end in itself. Our clients come to us because something has gone wrong in the business, and they need it fixed in a way that protects the enterprise and lets them get back to running it.

Disputes We Handle

Business litigation covers a wide range of disagreements between commercial parties. Our attorneys regularly handle matters involving:

  • Breach of contract – disputes over the meaning and enforcement of written and oral agreements, including supply contracts, service agreements, distribution arrangements, and commercial leases.
  • Partnership, shareholder, and LLC disputes – claims involving freeze-outs, breach of operating agreements, dissolution, valuation, and self-dealing by officers, directors, or managing members.
  • Breach of fiduciary duty – actions involving officers, directors, partners, and other parties who owe a duty of loyalty or care and have failed to meet it.
  • Business torts – fraud, intentional and negligent misrepresentation, interference with contractual relations, and interference with prospective economic advantage.
  • Unfair competition – claims under California’s Unfair Competition Law (Business and Professions Code § 17200), including disputes over deceptive trade practices and unlawful business conduct.


Whatever the underlying dispute, the goal is the same: an outcome that protects what the client has built.

Plaintiff and Defense Experience

Many firms take only one side of business cases. We do not. Our attorneys have extensive experience representing both plaintiffs and defendants in complex commercial litigation, and that dual perspective informs everything we do. Sitting across the table from sophisticated opposing counsel – and against well-funded defendants – has taught us where cases are won and lost. We bring that insight to plaintiffs who need to apply pressure on a larger adversary, and to defendants who need to neutralize a claim before it disrupts their business.

A Strategic, Not Reflexive, Approach to Litigation

Filing a lawsuit is the loudest tool in the kit, but it is rarely the only one. Before recommending litigation, we work with our clients to understand the business reality behind the dispute – the relationships at stake, the cost and disruption of a multi-year fight, and what a realistic resolution would look like. Sometimes a well-drafted demand letter and a focused mediation resolve the matter in weeks. Other times, the only way to protect a client is to file quickly, move for a temporary restraining order or preliminary injunction, and force the issue.

When a case does proceed in court, our attorneys are prepared to try it. We approach every matter with the assumption that it may end in front of a judge or jury, and we build the record accordingly – through targeted discovery, well-prepared witnesses, and motions that narrow the issues before trial.

Why Clients Choose Moore Ruddell

Our partners have spent more than two decades representing clients in high-stakes litigation at some of the largest law firms in the world. At Moore Ruddell, our clients receive that same caliber of legal work without the layered staffing and overhead of a global firm. The attorneys who pitch the case are the attorneys who handle it – there is no handoff to an unfamiliar associate after the engagement letter is signed.

We also take client communication seriously. Business disputes can drag on for months or years, and uncertainty about where a case stands is one of the most frustrating parts of the process. We make a point of keeping clients informed about status, next steps, and strategic choices, so the people whose business is on the line are never the last to know.
