Expertise that runs deep. Communication that builds trust. An approach that puts the client’s needs and objectives front and center.

Our firm is new; our relationships are not. Members of our team have worked together for decades.

Our principles

Kohn Dumain was founded on a simple belief: by remaining faithful to our core principles, we can set a higher standard for legal representation. Long before Brian and Ian became law partners, they built a relationship around a set of principles that continue to define our firm today. These principles guide every aspect of our practice, from the lawyers we hire, to the clients we represent to the advice we give.

Candor

Brian and Ian have spent over twenty-five years challenging each other’s thinking openly and directly. We believe our clients deserve the same directness: an honest assessment of the facts, the risks, and the likelihood of success, even when those conversations are difficult.

Discernment

We believe every important decision deserves careful judgment. We’re ready to fight for our clients in court, but we are equally prepared to advise against litigation or any course of action when we believe there is a better way to achieve the client’s objectives.

Ingenuity

Our lawyers never default to conventional thinking simply because it is familiar. With a deep understanding of the law, we recognize opportunities others overlook, anticipate challenges before they arise, and develop practical solutions tailored to each client’s objectives.

Loyalty

We believe the best relationships are built over time, which is why we measure ours in years, not months. We become trusted advisors who know our clients’ businesses, understand what matters to them, and remain invested in their success.

Stewardship

We take ownership of our clients’ legal challenges, protecting their interests and pursuing their objectives with the same care we would bring to our own, so they can focus on what matters most.

We help clients solve their most consequential legal and business problems with sound judgment, clear-eyed advice, and disciplined advocacy.

Kohn Dumain is based in New York, but our practice extends far beyond it.

Across the United States

We regularly represent clients in state and federal courts throughout the country, as well as in domestic and international arbitration proceedings. In jurisdictions where we appear regularly, such as Delaware, we work with trusted local counsel with whom we have longstanding relationships. Elsewhere, we draw on a broad network of experienced and respected lawyers to identify the right local partner for each engagement. In every matter, we remain responsible for the overall strategy, execution, and client relationship.

Throughout the world

Our clients’ matters often transcend geographic borders. We have represented clients in disputes involving parties, witnesses, evidence, and assets across North America, Europe, Asia, Africa, and the Middle East. Geography has never defined our practice. We go wherever our clients’ interests require, bringing the same thoughtful strategy, seamless coordination, and unwavering commitment to every matter, wherever it may arise or take us.
