A California business litigation attorney represents owners, partners, shareholders, and companies in disputes over ownership, contracts, competition, and fiduciary duties, in court or in arbitration. California law is distinctive in this field: it voids most employee non-compete agreements, protects trade secrets through its own statute, imposes fiduciary duties on partners and controlling owners, and enforces arbitration clauses unless they are unconscionable. Wade Litigation represents businesses and professional practices statewide and offers a case evaluation to review your agreements, your deadlines, and your options before a dispute escalates.
Searches about business disputes in California cluster around a few recurring questions: can my employer enforce a non-compete, can I sue a partner for breach of fiduciary duty, and how long do I have to file? This page answers those questions with the controlling statutes, then explains how business disputes move from first disagreement through trial and how county courts differ.
Non-Compete Agreements in California
California is one of the strongest states for workers when it comes to non-competes. Business and Professions Code section 16600 voids contracts that restrain anyone from engaging in a lawful profession, trade, or business, with narrow exceptions such as a covenant made in connection with the sale of a business or the dissolution of a partnership. Since January 1, 2024, section 16600.5 also voids any non-compete signed outside California if it would be void here, and it bars employers from enforcing one against a California-based worker regardless of where it was signed. Employers must not include a non-compete in an employment contract, and an employer who does so can face civil liability.

The practical result is that California businesses protect themselves differently. Confidentiality agreements, trade secret protection, carefully drafted non-solicitation terms limited to protecting trade secrets, and retention incentives do much of the work that non-competes do elsewhere. An owner who sells a business can still agree to a reasonable non-compete tied to the sale, and a partner leaving a partnership can be bound by a covenant tied to the dissolution. Whether an agreement falls into one category or another determines its enforceability.
Trade Secrets and Protecting Confidential Information
The California Uniform Trade Secrets Act, Civil Code section 3426 and following, protects information that derives independent economic value from not being generally known and that the owner takes reasonable steps to keep secret. Customer lists, pricing methods, source code, formulas, and strategic plans can qualify. A trade secret claim must generally be filed within three years after the misappropriation is or should have been discovered under section 3426.6. When a departing employee or competitor takes confidential information, speed matters, and our guide to protecting trade secrets in a competitive business environment explains how to preserve evidence and seek an injunction before the information spreads.
Plaintiffs in a trade secret case must identify the secrets with reasonable particularity before beginning discovery, under Code of Civil Procedure section 2019.210, a threshold requirement that many cases stumble over. Defendants often argue the information was publicly available or independently developed, so documentation of how the company protected the information from the start is central to the case.
Breach of Fiduciary Duty Among Partners and Owners
Business partners, managers, and controlling owners owe fiduciary duties of loyalty and care to the business and, in many structures, to each other or to minority owners. The duty of loyalty prohibits self-dealing, usurping business opportunities, and competing against the company. The duty of care requires reasonable diligence in managing the company’s affairs. A breach of fiduciary duty claim generally must be filed within four years under Code of Civil Procedure section 343, or three years if the claim is based on fraud. Our articles on fiduciary duty in business partnerships and disputes for shareholders and partners explain what each side must prove.

Partnership, LLC, and Shareholder Disputes
Most business disputes among owners come down to the documents. A partnership agreement, an operating agreement, or a shareholder agreement governs management authority, distributions, transfer restrictions, and exit rights; when the documents are silent, California’s default statutes fill the gaps. Deadlock between equal owners, claims of oppression by minority owners, disputes over buyout valuation, and challenges to transactions that benefit one owner at the expense of the company are recurring flashpoints. In serious cases, a court can order dissolution of a corporation or LLC, appoint a receiver, or order a buyout at fair value.
Structure also matters before a dispute begins. Our overview of business partnership structures in California explains how the choice among general partnership, LLC, and corporation affects liability and control, and our guide to steps to take when facing a shareholder lawsuit covers the first moves for a defendant.
Where California Business Disputes Come From
Business disputes in the state arise from a mix of sources. Owner and partner conflicts and contract breaches account for the largest share, followed by competition and trade secret disputes, employment disputes that overlap with ownership, lease disputes, and conflicts with investors and lenders. The chart below illustrates the pattern seen in practice rather than a statistical survey, and it highlights why the first step in any case is to read the governing documents and identify which type of dispute it really is.
Figure 3: Where California business disputes come from (illustrative mix from practice patterns).
Contract Disputes and Commercial Agreements
Contract breach claims require a valid contract, performance or excuse by the plaintiff, a breach, and damages, and they must be filed within four years for a written contract and two years for an oral one. Disputes often turn on ambiguous terms, on whether a condition was satisfied, or on whether a party has the right to terminate. Remedies include damages, specific performance in appropriate cases, and, if the contract allows, attorney fees. A prevailing-party fee clause is reciprocal under Civil Code section 1717, which changes the settlement calculation on both sides.
Arbitration Clauses and Choosing a Forum
Many commercial contracts require arbitration, and whether a clause applies is often the first contested question. California courts generally enforce valid arbitration agreements, but they refuse to enforce provisions that are unconscionable or that waive unwaivable statutory rights. Arbitration is private, usually faster, and offers very limited appeal rights, while litigation is public and allows full appellate review. Before filing, review the dispute resolution clause, any notice and cure requirements, and any pre-suit mediation obligation to avoid spending months in the wrong forum.
How a Business Dispute Escalates
Business disputes rarely begin in court. They usually start with a disagreement, move to a demand letter, and then to negotiation or mediation, with litigation following when those fail. Preserving documents early, writing a measured demand, and keeping communications professional all improve a party’s position at each stage. Mediation resolves a large share of disputes, particularly when the parties have an ongoing commercial relationship worth saving.

Injunctions, Receivers, and Emergency Relief
When conduct is causing harm that money cannot repair, such as misuse of trade secrets, a breach of an exclusivity covenant tied to a sale, or a partner’s removal of assets, a court can issue a temporary restraining order and a preliminary injunction. A court may also appoint a receiver to preserve assets or manage a business while the dispute is resolved. These remedies require a strong evidentiary showing and a willingness to post a bond, so courts use them selectively and only when the facts support them.
Professional Practices and Closely Held Companies
Medical, dental, legal, and accounting practices face particular issues because their value depends on the professionals who work in them. Disputes arise over compensation formulas, patient or client relationships after a departure, practice records, and buyout valuation. Restrictive covenants in these settings are analyzed under the sale-of-business and trade secret exceptions rather than as ordinary employee non-competes. The governing agreements and the facts about who brought which clients usually decide these matters.
Commercial Leases and Landlord Disputes for Businesses
A business tenant’s ability to operate often depends on its lease, and lease disputes are a steady source of litigation. Common conflicts involve tenant improvement obligations, common area maintenance charges, early termination, assignment and subletting, and the return of security deposits. Commercial leases are negotiated documents with far more variation than residential leases, so read default, notice, and cure provisions closely; a party that misses a cure deadline can lose rights it otherwise would have had.
Wage and Employment Exposure for Business Owners
California’s employment laws create exposure that surprises many owners, particularly around worker classification, overtime, and meal and rest breaks. A claim by a current or former worker can become an owner dispute when partners disagree about responsibility, when an insurer questions coverage, or when a buyer discovers undisclosed liabilities during a sale. Addressing classification and pay practices early, and understanding how they interact with the ownership structure, protects both the company and its owners personally.
Business Divorces and Succession
Family-owned businesses and closely held companies often face a form of business divorce when partners part ways or when a founder retires. Buy-sell agreements, valuation formulas, and informal understandings about succession are the main sources of conflict, and they are most contentious when the agreement was written years earlier and no longer fits the business. When a founder dies or a marriage ends, the business interest can also become a probate or family law issue, which we address on our probate and divorce pages.
How California Counties Differ for Business Cases
Business cases are filed in the superior court of the county where the defendant resides or the contract was performed, and larger counties assign complex commercial cases to specialized departments. The table summarizes verified information for the regions where Wade Litigation practices.

What This Means for Your Case
The strength of your written agreements and documentation usually determines how quickly a business dispute resolves. Gather the formation documents, operating or partnership agreement, the contracts in dispute, financial statements, and the key communications, and avoid taking action that could breach your own obligations while the dispute is pending. An early review identifies the claims, the likely forum, the applicable deadlines, and whether negotiation, mediation, or litigation is the most effective path.
Objections We Commonly Address
Owners sometimes avoid addressing a dispute because they fear the cost of litigation or the effect of suing a partner or long-time customer. In many cases, a quick, direct resolution before a relationship has completely broken down protects the business more than avoiding the conflict does, and a measured demand letter often opens a path to settlement.
What Happens When You Call
When you call Wade Litigation, the intake team asks about the company, the nature of the dispute, and the agreements that govern it, such as an operating agreement, shareholder agreement, or contract. During the case evaluation, an attorney assesses your position and outlines whether negotiation, arbitration, or litigation is the most effective route.

Frequently Asked Questions
Are non-compete agreements enforceable in California?
Generally no. Business and Professions Code section 16600 voids most employee non-competes, and section 16600.5 extends that rule to agreements signed in other states, with narrow exceptions for the sale of a business or dissolution of a partnership.
How long do I have to sue a business partner for breach of fiduciary duty?
Generally four years, or three years if the claim is based on fraud, though the start date can depend on when you discovered the breach.
What qualifies as a trade secret?
Information that has independent economic value because it is not generally known and that the owner takes reasonable steps to keep secret, such as customer lists, formulas, and methods.
Can a court dissolve a company?
Yes. In appropriate cases, such as deadlock or serious misconduct, a court can order dissolution, appoint a receiver, or order a buyout at fair value.
Do I have to arbitrate?
Only if your agreement contains a valid arbitration clause, which California courts generally enforce unless it is unconscionable.
Can I recover attorney fees in a business dispute?
If the contract has a prevailing-party fee clause, yes, and California applies such clauses reciprocally.
