John C. Leddy

Partner / New York

Overview

John C. Leddy is a trial lawyer who represents companies, investors, lenders, owners, funds, executives, and other sophisticated parties in complex commercial disputes throughout the United States. His practice is particularly focused on disputes where capital, control, and significant commercial relationships intersect.

A substantial part of John's practice involves commercial real estate finance, private credit, and distressed investments. He represents borrowers, owners, investors, guarantors, lenders, and other stakeholders in disputes involving commercial mortgage and mezzanine loans, CMBS loans and special servicers, guaranties and recourse obligations, workouts and forbearance arrangements, mortgage and UCC foreclosures, preferred equity, intercreditor relationships, and other issues arising from complex capital structures.

John also has significant experience litigating disputes among business owners and investors. He represents clients in joint venture, LLC, membership, partnership, and closely held company disputes involving control and management rights, capital contributions, distributions, redemption and exit rights, fiduciary duties, alleged self-dealing, removal rights, and other governance issues.

Beyond finance and investment disputes, John handles complex contract and business litigation across a range of industries. His matters have involved distribution and licensing agreements, payment and accounting obligations, intellectual property-related commercial relationships, brokerage and property management agreements, franchise relationships, financial services, technology, life sciences, consumer products, hospitality, and other significant commercial arrangements. His recent experience includes arbitrations involving television content distribution and licensing agreements, a licensing and accounting dispute involving pharmaceutical development, and counseling related to a sports industry venture.

John represents clients at every stage of a dispute, from pre-litigation strategy and workouts through trial, arbitration, and appeal. He appears in state and federal courts around the country and in domestic and international arbitrations. Clients also engage him before litigation begins to evaluate potential claims, assess litigation risk, preserve leverage, and develop solutions that account for both the legal dispute and the client's broader business objectives.

John also has a particular focus on the sports and media industries. His sports practice is focused on serving agents, client representatives, athletes, companies, and other industry participants as an outside resource when disputes, investments, business ventures, or other legal issues extend beyond the agency's core representation. He serves on both the Sports Law Committee and Litigation Committee of the New York City Bar Association.
