Why Choose Ghassemian Law Group for Commercial Litigation in Irvine, CA?

The right lawyer for a commercial case is one who understands both the legal framework and what a favorable outcome actually looks like for the business involved.

A Founding Attorney With 26 Years of Commercial Litigation Experience

Mahyar Ghassemian has practiced commercial and construction litigation in California since 1999. She earned her law degree Cum Laude from Western State University College of Law after completing a master’s in physics with honors at Cal State Long Beach. Commercial cases often hinge on financial records, technical specifications, or forensic reconstructions of events. As a business lawyer in Irvine, CA, her academic background translates directly into how she handles that material in complex disputes.

Outcomes Across Significant Commercial Matters

Our commercial litigation practice has produced multi-million dollar results for clients defending against substantial claims. Those outcomes include defeating individual liability for a client sued by a multi-billion dollar corporation, extracting shareholders from a $2.3 million corporate governance battle with equity preserved, recovering $800,000 for a general contractor on unpaid work, and defending a $3 million annual public contract against delay and defective work claims.

Legal Representation In Multiple Languages

Accessibility in a client’s own language shapes the quality of legal representation. Orange County has a substantial population of business owners whose primary language is not English, and handling a complex commercial case in a second language can leave important details unclear. Our attorneys speak English, Persian, Turkish, French, and conversational Spanish, which allows many clients to engage with their lawyer in their strongest language, review documents without paraphrase, and participate fully in the decisions that shape their case.

Community Involvement That Connects Us to Our Clients

Ms. Ghassemian actively supports the National Association of Women Business Owners, the Associated General Contractors, the Southern California Contractors Association, and the Orange County Bar Association. Spending time with the organizations our clients belong to keeps our practice grounded in what businesses actually face.

Types of Commercial Litigation Cases We Handle in Irvine

Commercial litigation reaches across nearly every area of business operations. Our practice focuses on disputes where the financial exposure or legal complexity warrants full-scale representation. The core areas we handle include:

• Breach of Contract Claims. Contract disputes drive a large share of commercial litigation in California. We handle written, implied, and oral agreements, including disputes arising from verbal contracts in California, which carry different evidentiary burdens than signed written ones.
• Shareholder and Partnership Disputes. When owners lose alignment, the company frequently suffers before the dispute is resolved. We’ve handled corporate governance battles, buyout negotiations, and deadlock situations where equitable relief was essential to keeping the business functional.
• Unfair Competition and Trade Secrets. California offers strong protections against misappropriation of proprietary information, customer lists, and personnel. We pursue and defend these claims under the California Uniform Trade Secrets Act and Business and Professions Code §17200.
• Breach of Fiduciary Duty. Officers, directors, partners, and managing members owe real duties, and breaches can expose the responsible parties to substantial damages. These cases require detailed attention to the governing documents and the conduct at issue.
• Fraud and Misrepresentation. Commercial fraud often surfaces after a deal closes, when financials or operational realities turn out to differ from what was represented. Recognizing fraud early often marks when a business needs a litigator, because preservation and strategic positioning matter from the start.
• Insurance Coverage Disputes. Business policies can cover more than owners assume, and insurers sometimes deny coverage or assign conflicted defense counsel. We handle direct coverage disputes and act as Cumis counsel when independent representation is required.
• Business Tort Claims. Interference with contract, interference with prospective economic advantage, conversion, and related claims appear frequently alongside contract disputes. The top business litigation case types in California often blend several of these theories in a single action.
• Corporate Governance Matters. Derivative suits, oppression of minority shareholders, and control disputes require both litigation skill and an understanding of how corporate authority actually operates day to day.

California Legal Requirements for Commercial Litigation

California law imposes specific deadlines and procedural requirements on commercial cases. A company that misses them can lose otherwise valid claims or defenses regardless of the underlying facts.

Limitations periods vary by claim. Breach of a written contract must be filed within four years under Code of Civil Procedure §337. Oral contract claims carry a two-year deadline under Code of Civil Procedure §339. Fraud claims generally must be filed within three years, though the discovery rule may delay the start of the clock when the wrongdoing was concealed, which is common in commercial fraud cases.

Trade secret misappropriation is governed by the California Uniform Trade Secrets Act, which authorizes injunctions, damages, and in some cases attorney’s fees. Claims under Business and Professions Code §17200 reach unlawful, unfair, and fraudulent business practices, with remedies focused on injunctive relief and restitution.

Most commercial matters proceed in California Superior Court, though contracts with mandatory arbitration clauses, federal question issues, or diversity jurisdiction may place the case in a different forum. Choice of forum affects discovery rules, timing, and strategy, and we assess that question early in every matter.

Important Aspects of an Irvine Commercial Litigation Case

Informed clients make sharper decisions about strategy, settlement, and risk. The considerations below shape nearly every commercial case we handle.

Evaluating the Claim and Defenses Before Responding

The initial response in a commercial case often locks in the direction of the dispute. Affirmative defenses must be raised early, cross-complaints must be filed with or shortly after the answer, and motions to strike or demur can eliminate claims before discovery ever begins. A rushed or formulaic response gives up leverage that rarely returns.

Building the Factual Record Through Discovery

Commercial litigation produces enormous volumes of documents, communications, and deposition testimony. The difference between effective discovery and wasted effort lies in targeting the elements that actually control the outcome. We structure discovery around what the case will turn on, not around what the rules technically allow.

Pursuing Injunctive Relief When Necessary

Some commercial harms cannot wait for trial. Trade secret theft, breach of non-compete agreements, and misuse of company assets often require immediate court intervention through temporary restraining orders or preliminary injunctions. California courts require strong evidentiary showings for this relief, and moving quickly with proper documentation is often essential to preserving a client’s position.

Managing Personal Liability Exposure

Corporate structures do not always shield owners completely. Personal guarantees, alter ego allegations, and direct tort claims can put individual assets at risk. A significant portion of our work in commercial cases involves structuring the defense to protect both the company and the individuals associated with it.

Settlement Strategy and Timing

Strong cases sometimes settle better after early motion practice establishes credibility. Others benefit from waiting until discovery exposes the weaknesses in the opposing position. Some never should settle at all. We advise clients on timing based on the actual state of the evidence, not on standard formulas.

The Real Cost of Litigation

Commercial cases involve meaningful investment in time, attorney fees, and expert costs. Clients deserve transparency about what each phase of the case will cost and what specific strategies aim to accomplish. We have those conversations upfront and revisit them as the case evolves, so that every major decision is informed by both the legal picture and the financial one.
