How Can an Orange County Business Attorney Help?

At Callahan & Blaine, we discourage our commercial and corporate litigation clients from thinking in terms of their roles as plaintiffs or defendants.

Frequently Asked Questions

What is the difference between commercial litigation and business litigation?

Commercial litigation and business litigation are often used interchangeably, though commercial litigation typically refers to disputes involving commercial transactions, contracts, and business-to-business disputes. Business litigation is a broader term that encompasses commercial disputes as well as internal corporate matters like shareholder disputes, partnership dissolution, and corporate governance issues. At Callahan & Blaine, we handle both commercial and corporate litigation matters. Our attorneys represent corporate, professional, and entrepreneurial clients of all sizes, from multi-national Fortune 500 companies to California-based corporations, medium and small businesses, homeowners associations, and individuals engaged in business.

The decision to file a lawsuit or pursue settlement depends on numerous factors, including the strength of your legal position, the amount at stake, business relationships involved, time considerations, and your strategic business objectives. At Callahan & Blaine, we discourage clients from thinking strictly in terms of their roles as plaintiffs or defendants. Most cases we handle involve counterclaims, cross-claims, and third-party practice. What might have begun as a contract action against your company could be dwarfed by the antitrust or fraud claims you can pursue against opponents. Our attorneys evaluate each situation strategically and integrate outstanding trial skills with sophisticated litigation strategy and resourceful legal dispute resolution tactics.

Business litigation in California typically takes 18 to 36 months to resolve, though complex cases involving multiple parties, extensive discovery, or novel legal issues may take longer. The timeline depends on court scheduling, the complexity of factual and legal issues, the number of witnesses and documents involved, motion practice, and whether parties engage in settlement discussions or alternative dispute resolution. Cases that proceed to trial will naturally take longer than those resolved through early settlement or mediation. Our attorneys work efficiently to advance your case while pursuing the most favorable outcome for your business interests.

Callahan & Blaine has been focused on civil trial practice since opening our doors in 1984, with complex business litigation forming the central core of our work. We now have more than 20 trial lawyers with concentrated experience across a wide variety of legal disciplines. Every attorney we hire has demonstrated outstanding trial lawyer skills before joining our firm and can handle critical roles in complex or high-stakes litigation. Our experience and focus have led to favorable settlements or verdicts in all of the civil litigation disputes we have handled. Our track record includes the largest jury verdict in Orange County history – $934 million – and over $1 billion in verdicts and settlements. Each of our attorneys brings a minimum of 8 years trial experience.

A shareholder derivative action is a lawsuit brought by a shareholder on behalf of a corporation against parties who have allegedly harmed the corporation, typically directors, officers, or controlling shareholders. These cases arise when corporate leadership fails to take action against wrongdoing that has damaged the company. Common claims include breach of fiduciary duty, self-dealing, corporate waste, and fraud. Callahan & Blaine has extensive experience representing both shareholders bringing derivative actions and corporations and directors defending against such claims. Our attorneys understand the complex procedural requirements and substantive legal issues involved in shareholder derivative litigation.

Business litigation involves resolving disputes through the court system or alternative dispute resolution methods like arbitration or mediation. Transactional business law focuses on structuring business relationships, drafting contracts, negotiating deals, and providing preventative legal counsel to avoid disputes. At Callahan & Blaine, we handle both business litigation and transactional and corporate law matters. Our litigation experience informs our transactional practice, allowing us to draft agreements and structure transactions that minimize litigation risk. Conversely, our understanding of business transactions strengthens our ability to litigate complex commercial disputes effectively.

Many business disputes can be resolved through alternative dispute resolution methods like mediation or arbitration, which may offer advantages including faster resolution, reduced costs, confidentiality, and more flexible procedures than traditional litigation. Whether mediation or arbitration is appropriate depends on various factors, including the nature of the dispute, the relationship between parties, contractual obligations, and strategic considerations. Some business contracts contain mandatory arbitration clauses. Callahan & Blaine has extensive experience with mediation, arbitration, and traditional litigation. Our Managing Partner Edward Susolik has handled over 1,500 mediations in 33 years, making him one of the leading insurance and business dispute resolution experts.

While no strategy can completely eliminate litigation risk, businesses can take proactive steps to minimize exposure. These include drafting clear, comprehensive contracts with experienced legal counsel, maintaining thorough documentation of business decisions and transactions, implementing strong corporate governance practices, protecting intellectual property and trade secrets through proper agreements and security measures, conducting regular legal audits of business practices, providing employee training on compliance issues, and seeking legal counsel before making major business decisions. Callahan & Blaine provides both preventative legal counsel to help businesses avoid disputes and aggressive representation when litigation becomes necessary.

If you receive a lawsuit or demand letter, contact experienced business litigation counsel immediately. Do not ignore the documents, as failure to respond within required timeframes can result in default judgment against your business. Do not destroy any documents related to the dispute. Avoid discussing the matter with opposing parties or posting about it on social media. Gather all relevant documents, contracts, communications, and evidence related to the dispute. Contact Callahan & Blaine at (714) 241-4444 for immediate legal counsel. Our attorneys will evaluate your legal position, explain your options, and develop a strategic response to protect your business interests.
