🇮🇹 La Legge Commerciale: Top 10 Commercial Law Firms in Italy

🇮🇹 Key Drivers of the Italian Legal Market
-
The M&A Elite: The five premier Italian independent firms (BonelliErede, Chiomenti, Gianni & Origoni, Legance, and PedersoliGattai) are consistently mandated on the country’s most significant domestic and inbound M&A, often competing directly against global firms.
-
Banking & Finance: Firms like Clifford Chance and Legance dominate the structured finance, securitisation, and project finance sectors, which are vital for Italy’s energy and infrastructure needs.
-
The Foreign Investment Bridge: International firms (Latham & Watkins, Allen & Overy, White & Case) are crucial for US and UK investment funds, bringing deep expertise in common law and high-value private equity transactions into the Italian market.
-
Competition and Regulatory: Given Italy’s historical emphasis on regulated sectors (energy, banking, utilities), firms with strong EU and Competition Law expertise, such as Freshfields (highly active but not listed in the Top 10 by volume), are essential for large corporate projects.
