Mr. Zelko has practiced for over 25 years in the areas of complex commercial and shareholder litigation, construction law, real estate, and commercial transactions.  He has counseled and represented clients in a broad range of industries ranging from multinational Fortune 500 and publicly traded companies to start-up ventures and small businesses. 

Mr. Zelko works closely with his clients as soon as potential litigation emerges to resolve claims within the client’s fiscal constraints and business objectives.  Mr. Zelko’s experience in complex litigation provides him with a unique perspective and invaluable insight in negotiating construction, real estate and commercial transactions for his clients so that they may avoid transactional pitfalls and reduce the risk of adverse litigation in these ventures.  Given this experience, he often serves as outside general counsel to his clients.

Mr. Zelko has successfully represented clients in state and federal courts, appellate courts, and in arbitration proceedings and mediation.  In his litigation practice, Mr. Zelko focuses on complex commercial and shareholder litigation matters, including construction litigation, shareholder derivative actions in closely held corporations, “business divorce” and partnership disputes, breach of contract claims and commercial lease actions.  In the arena of construction litigation, Mr. Zelko has litigated a myriad of construction matters including defective construction, delay damages, lien and payment disputes, trust fund diversion claims, improper underpinning of adjacent buildings and RPAPL §881 actions for access to and protection of adjacent properties during construction.

In his construction practice, Mr. Zelko routinely represents developers, property owners, general contractors and subcontractors and utilizes this wide experience to counsel his clients so that they may confidently navigate the challenges and risks of each project.  He counsels clients in all aspects of construction during the course of their projects, including change order issues, delays, non-payment claims and liens, defective construction, project close-out issues and termination as these issues may arise in a given project.  Mr. Zelko also counsels project owners and adjacent owners regarding access to neighboring properties for construction projects and negotiates license agreements for access and protection under the RPAPL §881 framework.
