Global insurance broker Lockton has announced the formalisation of its Global Transaction Liability practice, a move that solidifies the firm’s commitment to providing clients with a unified, expert-led approach to managing transaction risk across all major M&A markets.
Over the past three years, Lockton has placed more transaction liability policies in North America than any other broker.
This new global structure is designed to export that successful model, centered on technical rigor, consistency, and long-term client partnership across its international footprint.
The global practice will be co-led by Lockton’s U.S. Transaction Liability leadership team: Josh Halpern, Matt Heinz, Gaurav Sud, and Eric Ziff.
“Transaction liability is a highly technical advisory discipline,” said Josh Halpern, Global Co-Head, Transaction Liability. “As transactions increasingly span jurisdictions, clients need advice that combines deep local market expertise with a globally consistent approach. Formalising our global platform allows us to deliver that standard of technical excellence wherever deals are being done.”
Central to this expansion is the appointment of Mary Duffy as Head of Global Expansion and Market Strategy, Transaction Liability.
Duffy joins Lockton following 13 years at AIG, where she was Global Head of Mergers & Acquisitions Insurance, overseeing the largest global transaction liability insurer.
She started her career in the sector at a large global broker, founding its North America transaction liability practice.
“Mary brings a rare combination of institutional knowledge, global operating experience, and deep technical credibility,” said Matt Heinz, Global Co-Head, Transaction Liability. “She has been directly involved in the evolution of transaction liability products across regions and market cycles. That perspective is invaluable as we continue to build a platform designed to serve sophisticated clients on a global basis.”
“What drew me to Lockton was the seriousness of its commitment to building a truly global transaction liability platform,” said Duffy. “The firm is investing in technical depth, integration across regions, and a consistent approach to advising clients, rather than simply expanding footprint. That focus on quality and alignment is what enables clients to engage with confidence across borders.”
Lockton is also doubling down on the APAC region, led by Terence Montgomery. With over two decades of experience and a background as the former Head of M&A Asia-Pacific at another global brokerage, Montgomery is tasked with navigating the diverse and nuanced regulatory environment across Asia.
“Asia-Pacific is a diverse and highly nuanced market, and success there depends on both regional insight and global connectivity,” said Gaurav Sud, Global Co-Head, Transaction Liability. “Terence brings exceptional expertise across a significant range of jurisdictions and transaction types, and he has quickly become a central part of our global team.”
These appointments build on Lockton’s recent global investments in transaction liability, including the establishment last year of dedicated practices in Latin America, led by Bruna Reis, and in India, led by Anand Kaul, as well as continued growth in the UK and the Nordics.
