Litigation

  • Representation of businesses, institutions, public entities, and individuals in complex commercial and civil disputes in state and federal courts, administrative proceedings, arbitration, and mediation
  • From routine business disputes to high-stakes “bet-the-company” cases across commercial, construction, employment, environmental, healthcare, product liability, real estate, and fiduciary matters
  • Breach of contract, shareholder and partnership disputes, fraud and financial misconduct, employment and professional liability claims, environmental cost recovery actions, construction and real estate disputes, and catastrophic personal injury matters

Greenbaum is broadly acknowledged as the home of one of New Jersey’s premier litigation teams, with a longstanding and well-earned reputation for the effective representation of clients across a comprehensive range of practice areas. We represent small businesses, middle market companies, multinational entities and institutional firms operating in a wide variety of industries. We also represent trade associations, public sector entities, and individuals including corporate executives and shareholders.

Our most significant resource is the broad and diversified experience of our litigators. We have litigated virtually every type of business, commercial or personal dispute. Our attorneys appear regularly in New Jersey state and federal courts, before regulatory agencies and other governmental bodies, and in mediation and arbitration proceedings.  The matters we handle range from routine disputes and “cost of doing business” cases to complex litigation, including high-profile “bet the company” conflicts. Regardless of the size and nature of the matter, we start with an understanding of the client's specific goals and expectations.

Some litigation cases are best resolved through negotiation, while others must proceed to trial or arbitration and the outcome defended or challenged on appeal. The planning and implementation of an appropriate litigation strategy to meet a client’s goals and objectives involves more than legal and factual analysis – business or personal circumstances, and financial considerations must always be part of the equation. Our objective is to master the facts of a specific case and the applicable law, analyze the big picture, and move ahead with a winning strategy.
