What to Do When Your Business Is Sued in California: A Step-by-Step Guide

Introduction 

Opening a letter containing notice of a lawsuit is one of the most stressful moments a business owner can face. The fear of financial loss, damage to your reputation, and potential business closure can feel overwhelming. According to the Small Business Administration (SBA), the risk of being sued ranks among the top concerns for small and mid-sized companies across the United States. 

The stakes are high. If your business is sued and the lawsuit succeeds, you could face significant damages, lost revenue from disrupted operations, and lasting harm to your company's reputation. Common lawsuits filed against California businesses include breach of contract claims, employment disputes, partnership disagreements, discrimination cases, and premises liability issues. Whistleblower suits and regulatory compliance violations are also becoming increasingly frequent. 

But here's what you need to know right now: how you respond in the first days after receiving notice of a lawsuit can determine the entire outcome of your case. In California, the clock starts ticking immediately, and missing critical deadlines can result in an automatic loss. This guide provides the essential steps every business owner must take when facing legal action. 

Understanding Your Response Timeline in California 

Time is your most valuable resource when your business is sued. The deadline to respond depends on which court system is handling your case, and these timelines are strictly enforced. 

Federal Court Lawsuits: If your business is being sued in federal court, you have just 21 days to file your answer or response to the complaint. This compressed timeline emphasizes why immediate action is essential. Federal cases often involve claims that exceed $75,000 or disputes involving parties from different states. 

California State Court Lawsuits: For lawsuits filed in California state court, you typically have 30 days to file your response after being personally served with the complaint. While this provides slightly more time than federal court, 30 days passes quickly when you're managing your business and building a legal defense. In some cases, you may receive a demand letter or pre-suit notice before the formal complaint is filed, which can provide additional preparation time. 

Small Claims Court: If the claim is for $10,000 or less, the lawsuit will be filed in Small Claims Court. These cases follow different procedures and often allow for informal resolution through direct negotiation with the plaintiff or mediation services available through Los Angeles County and the Center for Conflict Resolution. However, even small claims require prompt attention and strategic response. 

Missing these deadlines has severe consequences. If you fail to respond within the required timeframe, the court will allow the plaintiff to file for a default judgment. This means they win automatically, and you lose your right to defend yourself or present evidence. The plaintiff can then enforce the judgment against your business assets, bank accounts, and property. 

First Steps to Take When Your Business Is Sued 

Read and Analyze the Complaint Carefully 

The complaint is the legal document that outlines why the plaintiff believes your business harmed them and what damages they're seeking. This document is typically filled with legal terminology that can be difficult for business owners to interpret without experience in California business law. Your first priority is understanding the legal grounds for the lawsuit. What specific actions or omissions does the plaintiff claim caused them harm? What laws or contractual obligations do they allege you violated? 

Take time to read through the entire complaint multiple times. Note the specific allegations, the amount of damages requested, and any deadlines mentioned. Pay attention to whether the plaintiff is an individual, another business, a former employee, or a government agency, as this affects the nature of the defense you'll need to build. Understanding the complaint is the foundation for everything that follows, which is why consulting with an experienced business litigation attorney immediately after receiving the complaint is so important. 

Never Contact the Plaintiff Directly 

Your instinct may be to pick up the phone and try to resolve the matter directly with the person or entity suing your business. This is one of the most dangerous mistakes you can make. Any communication you have with the plaintiff before consulting an attorney can be used against you in court. Your words can be misinterpreted, taken out of context, or twisted into statements that appear to admit liability even when that wasn't your intention. 

California courts allow virtually any communication to be introduced as evidence. A casual conversation meant to clarify a misunderstanding can become the centerpiece of the plaintiff's case against you. Even apologizing for a situation, which might seem like common courtesy, can be presented as an admission of wrongdoing. Once you've received notice of a lawsuit, all communication with the plaintiff should go through your attorney. This protects your legal position and ensures that every statement is strategically sound. 

Gather and Organize All Relevant Documents 

Building a strong defense requires evidence, and that evidence exists in your business records. Start immediately organizing every document that relates to the allegations in the complaint. This might include contracts, emails, text messages, invoices, receipts, payroll records, employee handbooks, partnership agreements, meeting minutes, photographs, or video footage depending on the nature of the claim. 

Create a comprehensive checklist of documents you'll need and systematically gather each item. Make copies of everything rather than working with originals. If the lawsuit involves a contract dispute, gather the signed contract, any amendments, correspondence about the contract terms, and records of performance by both parties. For employment-related lawsuits, collect the employee's personnel file, performance reviews, disciplinary records, and documentation of any complaints or incidents. For partnership disputes, compile your operating agreement, financial statements, communication between partners, and records of business decisions. 

Organization is critical because your attorney will need to review these documents to understand your position and build your defense strategy. The more organized and complete your documentation, the more effectively your attorney can represent you. Additionally, California courts have discovery rules that will eventually require you to produce relevant documents to the other side, so having them organized early streamlines the entire process. 

Contact Your Insurance Agent Immediately 

Many California business owners carry insurance policies that provide coverage for lawsuits, but this protection only applies if you follow the proper notification procedures. Commercial general liability insurance, professional liability insurance (errors and omissions), employment practices liability insurance, and directors and officers insurance may all provide coverage depending on the type of lawsuit. 

Review your insurance policies or contact your agent to determine whether your current situation is covered. Insurance companies typically have strict requirements about when and how you must notify them of a potential claim. Some policies require notification within days of receiving a complaint. If you miss these notification deadlines, your insurance company may deny coverage even if the policy would otherwise protect you. Your insurance company may also provide or pay for legal representation, but you need to understand the terms of this coverage and whether you have the right to select your own attorney. 

Don't assume a claim isn't covered without checking. Sometimes coverage applies in ways that aren't immediately obvious. For example, a contract dispute might trigger coverage under certain circumstances, or an employment claim might be covered even if you thought you only had general liability protection. 

California law requires your response to be in a specific legal format and address each allegation made in the complaint. Your response must be filed with the same court where the complaint was filed and properly served on the plaintiff or their attorney. This isn't simply a letter explaining your side of the story. It's a formal legal document that must comply with California Code of Civil Procedure requirements. 

Your response should specifically admit or deny each numbered paragraph in the complaint. For allegations you don't have enough information to confirm or deny, you can state that you lack sufficient knowledge. Your response should also include any affirmative defenses you plan to raise. An affirmative defense is a legal argument that, if proven true, defeats the plaintiff's claim even if their basic allegations are accurate. Common affirmative defenses in California business litigation include statute of limitations, waiver, estoppel, failure to mitigate damages, and comparative fault. 

The response must also address whether you're demanding a jury trial, as this right can be waived if not properly asserted. You may also file counterclaims if you have legal claims against the plaintiff arising from the same situation. All of these elements require knowledge of California court procedures and legal strategy, which is why business owners should never attempt to draft and file responses without experienced legal counsel. 

Ignoring the lawsuit is never an option. Failing to respond within the 30-day deadline (or 21 days for federal court) allows the plaintiff to obtain a default judgment against your business. This means they automatically win, and the court can award the full amount of damages they requested. A default judgment can be enforced against your business assets, and removing a default judgment once it's entered is extremely difficult and often impossible. 

The complexity of California business litigation makes professional legal representation essential, not optional. The legal system has specific procedural rules, filing requirements, and strategic considerations that directly impact the outcome of your case. An experienced business litigation attorney brings several critical advantages to your defense. 

First, your attorney will translate the legal jargon in the complaint into plain language so you understand exactly what you're facing. They'll identify the strengths and weaknesses of the plaintiff's case and your potential defenses. Second, they'll develop a comprehensive defense strategy tailored to your specific situation. This includes gathering evidence, identifying and interviewing witnesses, conducting legal research, and determining the best procedural approaches to protect your interests. 

Third, your attorney handles all communication with the plaintiff and their legal team, ensuring nothing you say can be used against you. They'll also manage all court filings, ensure deadlines are met, and handle the technical aspects of litigation that can trap unwary business owners. Fourth, many lawsuits settle before trial, and an experienced attorney knows how to negotiate effectively to achieve favorable settlements that protect your business. They understand what reasonable settlement ranges look like and can advise you on when to settle versus when to proceed to trial. 

Finally, if your case goes to trial, you'll need someone who understands courtroom procedures, evidence rules, and how to present your case persuasively to a judge or jury. California trial practice has numerous technical requirements that must be followed precisely. One procedural misstep can result in critical evidence being excluded or your case being dismissed. 

The cost of hiring an attorney is almost always less than the cost of losing a lawsuit by default or making critical strategic errors. Many business litigation attorneys offer initial consultations to evaluate your case and discuss representation options. This investment in professional legal help is an investment in protecting your business, your livelihood, and your legacy. 

What Happens If You Ignore a Lawsuit 

Some business owners, faced with the stress of a lawsuit, make the catastrophic mistake of ignoring it. They hope the problem will go away, or they convince themselves that the plaintiff's claims are so baseless that the court won't take them seriously. This is dangerous thinking that leads to devastating consequences. 

If you don't respond to the complaint within California's deadline, the plaintiff will file a Request for Entry of Default with the court. This document asks the court to enter a default against you because you failed to respond. Once the default is entered, the plaintiff can proceed to request a default judgment. At this point, you've lost your right to defend yourself, present evidence, or argue your side of the case. 

The court will then conduct a default prove-up hearing where the plaintiff presents evidence of their damages. You won't be present to challenge this evidence or cross-examine witnesses. The judge will typically grant the full amount of damages the plaintiff requests, plus court costs and attorney's fees if the law allows. This judgment becomes a legally enforceable court order. 

Once the plaintiff has a judgment, they can use California's collection laws to seize your assets. This includes garnishing your business bank accounts, placing liens on your property, and levying your accounts receivable. They can force the sale of business assets to satisfy the judgment. For judgments against a business owner personally, they can also garnish wages, place liens on homes, and seize personal property. 

A default judgment appears on credit reports and public records, damaging your business reputation and making it difficult to obtain financing, secure contracts, or maintain vendor relationships. The judgment collects interest at California's statutory rate (currently 10% per year), so the amount you owe grows larger every year it remains unpaid. 

Setting aside a default judgment after it's entered is extremely difficult in California. You must show that the default resulted from excusable neglect, which is a high legal standard. Courts are generally unsympathetic to business owners who simply ignored a lawsuit. Even if you later discover that the plaintiff's claims were weak or entirely false, you've lost your opportunity to prove this in court. 

Protecting Your Business During Litigation 

Beyond the immediate steps of responding to the lawsuit, business owners should take additional measures to protect their company during pending litigation. Continue operating your business as professionally as possible. Maintain detailed records of all business activities, as new evidence relevant to the lawsuit may emerge. Ensure your employees understand they should preserve all documents and communications related to the case. 

Be cautious about discussing the lawsuit with anyone other than your attorney. California's attorney-client privilege protects conversations with your lawyer, but discussions with employees, friends, family members, or business associates are not protected and can be discovered by the opposing party. Avoid posting about the lawsuit on social media, as these posts are frequently used as evidence in litigation. 

Consider the financial impact of the lawsuit on your business operations. Work with your attorney to understand the potential range of outcomes and ensure you have plans in place to manage your business regardless of how the litigation progresses. This might include securing additional financing, adjusting business operations, or implementing risk management procedures to prevent similar claims in the future. 

If the lawsuit involves employment claims, partnership disputes, or other internal business matters, be mindful of how this affects ongoing business relationships. Work with your attorney to determine what information can be shared with partners, employees, or stakeholders without compromising your legal position. 

Conclusion 

Facing a lawsuit is one of the most challenging situations a California business owner can encounter, but prompt, strategic action gives you the best chance of protecting your business and achieving a favorable outcome. The steps you take in the first days after receiving notice of a lawsuit set the foundation for your entire defense. 

Remember that California's strict response deadlines leave no room for delay. Whether you're facing a federal lawsuit with a 21-day deadline or a state court case with 30 days to respond, every day counts. Read the complaint carefully, avoid direct contact with the plaintiff, organize your documents systematically, notify your insurance company immediately, and prepare a legally sound response. 

Most importantly, don't try to handle business litigation alone. The complexity of California's legal system and the high stakes involved make professional legal representation essential. An experienced business litigation attorney will protect your rights, develop a strong defense strategy, and work to achieve the best possible resolution for your business.
