Decisive advocacy for businesses in high-stakes disputes

Complex Commercial Litigation

When a dispute threatens your business, you need experienced trial counsel who can navigate the complexity. As a Chicago boutique litigation firm, we represent small and mid-sized businesses, startups, and their owners across the full spectrum of complex commercial litigation — from business torts and tortious interference to fiduciary-duty breaches and partnership disputes.

Litigation Counsel for Small and Mid-Sized Businesses

Small and mid-sized businesses face the same high-stakes disputes as large companies — often without an in-house legal team to manage them. As a Chicago boutique litigation firm, we serve as outside litigation counsel for founders, owners, and growing companies, handling contract disputes, business torts, partnership and shareholder conflicts, and disputes with competitors, vendors, and former employees. You work directly with the attorneys on your case — trial advocacy combined with commercial and IP litigation experience — so you get firm-level capability with the responsiveness of a boutique practice.

Commercial Litigation Strategy

Complex commercial disputes often involve overlapping legal theories, multiple parties, and significant financial exposure. We bring a strategic, results-oriented approach to every case — identifying the strongest claims and defenses early, pursuing targeted discovery, and positioning each matter for the best possible outcome, whether through negotiation, mediation, or trial. We litigate complex commercial disputes in Cook County Circuit Court, the Northern District of Illinois, and courts across the state.

Business Torts and Unfair Competition

Beyond breach of contract, many business disputes involve tortious conduct — a competitor that lures away your customers or employees, a former partner who diverts a corporate opportunity, or a third party who interferes with your contracts and relationships. We litigate the full range of business torts, including tortious interference with contracts and business expectancies, breach of fiduciary duty, unfair competition, and diversion of corporate opportunities. These claims often travel together, and we identify every viable theory to maximize your leverage and recovery.

Tortious Interference with Contractual Relations

When a third party intentionally induces another to breach a contract with you, the law provides a remedy. We handle claims for tortious interference with existing contracts, pursuing damages for the harm caused to your business relationships and lost economic opportunities. Under Illinois law, tortious interference claims require proof of intentional and unjustified conduct as established in Illinois Appellate Court precedent.

Tortious Interference with Business Expectancies

Even without a formal contract, you may have protectable business relationships and reasonable expectations of future business. We pursue claims against parties who use improper methods to interfere with these prospective economic advantages.

Corporate & Partnership Disputes

Officers, directors, and partners owe fiduciary duties of loyalty and care. When those duties are breached — through self-dealing, mismanagement, or diversion of corporate opportunities — we pursue claims to recover damages and protect your interests in the business.

Agent & Trustee Liability

Fiduciary relationships extend beyond the corporate setting. Agents, trustees, financial advisors, and others in positions of trust can be held accountable when they fail to act in your best interest. We handle claims involving misappropriation, unauthorized transactions, and failures to disclose conflicts of interest.

When Your Business Is Sued

If your company has been served with a complaint, the early decisions matter. Deadlines to answer or to remove a case to federal court run quickly, and the wrong first move can forfeit defenses or leverage. We move fast to assess exposure, preserve documents, evaluate counterclaims, and develop a defense strategy aimed at the best possible outcome — whether that is an early dispositive motion, a negotiated resolution, or trial. We defend businesses in contract, business-tort, partnership, and fiduciary-duty suits in Illinois state and federal court.
