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.

⭐⭐⭐⭐⭐ “I have had the pleasure of working with Ghassemian Law Group, and I consider them one of the great ones. Their prompt responses, meticulous attention to detail, and compassionate approach are truly commendable. I highly recommend their services.” — Kadi Brandel

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.

Commercial Litigation Statistics in Irvine, CA

Irvine sits at the center of Orange County’s economy. The City of Irvine reports that 49 of the top 100 publicly traded companies headquartered in Orange County are based here, and those firms account for the large majority of that group’s combined market value. More companies packed into one city means more contracts, more partnerships, and more of the disputes that follow.

Most of those disputes end up in the civil courts. California’s trial courts handle millions of cases each year, and the larger business matters are filed as unlimited civil cases, where discovery and motion costs climb fast. The California court data tracks that caseload year over year. The volume is one reason so many Irvine businesses keep a commercial litigation attorney within reach before trouble starts.

Mistakes That Can Damage Your Commercial Litigation Case

We see the same avoidable errors cost Irvine companies leverage, money, and sometimes the case itself. Most of them happen in the first few weeks, before a lawyer is ever involved. Knowing them ahead of time protects your position.

• Deleting documents and messages. The moment a dispute becomes foreseeable, a duty to preserve evidence attaches. Emails, text threads, accounting files, and old drafts all count. Routine auto-deletion is no excuse. Destroying material can lead to sanctions and an adverse inference, where the court assumes the missing records would have affected your case. The safest move is to freeze deletion the day a conflict surfaces, which matters most for any company that has already been sued.
• Waiting too long to act. California sets firm deadlines. A claim for breach of contract on a written agreement generally must be filed within four years, and an oral agreement carries a two-year window. You can confirm the basic filing deadlines through the California Courts self-help guide. Miss the date and a strong claim disappears no matter how clear the underlying facts are.
• Talking to the other side directly. Once a dispute surfaces, casual calls and emails to the opposing party tend to produce admissions. One sentence pulled out of context can reshape the whole matter. Route communication through counsel and keep your own statements off the record.
• Ignoring a demand letter. A demand letter is often the last quiet moment before a lawsuit. Letting it sit forfeits the chance to resolve the matter early or to position your company before litigation begins. This is usually the point to involve a litigator, not after the complaint arrives.
• Blurring personal and business finances. When owners commingle funds or skip corporate formalities, opponents argue alter ego and reach for personal assets. How you structure your business directly affects whether that argument gains traction in court.
• Relying on a handshake. Verbal agreements can be enforceable in California, but proving the terms without a writing is slow and expensive. Disputes that begin without a written contract usually come down to memory and credibility, which is a hard way to win.
• Posting about the dispute. Social media comments and press statements become evidence. Even a vague post can undercut your own claim or hand the other side a counterclaim.
• Going it alone for too long. Early decisions set the trajectory of a case. Companies that bring in business litigation counsel only after the damage is done almost always spend more to recover less.

Irvine Commercial Litigation Lawyer FAQs

How much does a commercial litigation lawyer in Irvine cost?

Most commercial cases are billed hourly, and the total depends on complexity, the volume of discovery, and whether the matter settles or goes to trial. We talk through fees and likely cost ranges at the outset, then revisit them as the case develops, so you are never left guessing. Our consultations are free. For a general sense of what a lawsuit costs, the early phases tend to run lower than full trial preparation.

Do you offer free consultations?

Yes. We offer a free consultation for commercial litigation matters in Irvine, CA. You speak with an attorney who reviews the facts, flags the legal issues that actually control the outcome, and gives you an honest read on where the dispute stands. There is no obligation to hire us afterward. The goal of that first meeting is clarity.

How long will my commercial case take?

It depends. Some disputes resolve in months through early motions or settlement. Complex cases with heavy discovery can run a year or more. California’s complex civil matters are managed on a separate track to keep them moving. We give you a realistic timeline at the start and update it as circumstances shift. For background, here is more on how long lawsuits take.

I was just served with a lawsuit. What should I do?

Act quickly. In California you generally have 30 days to respond to a complaint, and missing that window risks a default judgment. Preserve your documents, stop contacting the other side, and call a commercial litigation attorney right away. The first response often locks in the direction of the case, including any cross-complaint or early motion, so those decisions are worth getting right.

Can we recover our attorney’s fees if we win?

Sometimes. California follows the American rule, where each side pays its own fees unless a contract or statute says otherwise. Many business agreements include a prevailing-party fee clause, which can shift fees to the losing side. We review your contracts early to see whether fee recovery is realistically on the table, since that answer often changes how aggressively a case should be litigated.

What if a business partner breached their duty to the company?

Officers, directors, and managing members owe fiduciary duties, and a breach can expose them to real damages. These cases turn on the governing documents and the specific conduct. We handle claims involving self-dealing, diverted opportunities, and misuse of company funds. If you are weighing whether to sue a business partner, an early case assessment usually saves money down the line.

Should my dispute be in state or federal court?

Most commercial litigation in Irvine proceeds in Orange County Superior Court. Federal court can apply when the parties are citizens of different states and enough money is at stake, or when a federal law controls the claim. The forum affects discovery rules, timing, and strategy, so we assess that question at the very start of every matter rather than after filing.

Do you only represent businesses, or individuals too?

We represent companies and the individuals tied to them, including owners facing personal exposure through guarantees or alter ego claims. We typically step in when the amount in controversy is significant. Whether you need business dispute counsel or a defense against a major claim, we will tell you honestly whether litigation is the right move.
