  • History of the law firm

    A brief history of N&T


    N&T began in 1991, when Péter Nagy and László Trócsányi, having worked in New York and Brussels respectively, returned to Hungary to start their own law firm in Budapest. Within a year, the firm was up and running and had evolved into a full-service commercial law firm, with over a dozen specialized attorneys advising and acting for clients in virtually every area of international private and commercial law. N&T quickly built a strong reputation, which was cemented in 1998 when it entered into an association with Coudert Brothers LLP, a leading multinational law firm. From 2002 until 2024, N&T was the sole Hungarian member of Lex Mundi, the world’s leading network of independent law firms.


    To serve the needs of its global client base, N&T continued to expand and was joined by many outstanding partners and associates, among them well-known law professors. N&T alumni went on to serve variously as President of the Republic of Hungary, Constitutional Court judge, ambassador, Hungary’s Minister of Justice, EU General Court judge, European Commission officer and Member of the ICC International Court of Arbitration.


    Over the years, among countless other complex and fascinating matters, N&T has acted for clients involved in Hungary’s largest ever privatization; its largest ever energy construction project; and its largest ever litigation by disputed sum. N&T has carved out a name for itself advising sophisticated international clients, and its excellent reputation among its peers is reflected in the firm’s ratings by Chambers, Legal 500 and other similar organizations.
