A U.S. legal capability is the missing piece for KPMG International’s global legal services, Stuart Fuller, the firm’s recently retired global head of legal services, said in an interview with Law.com International ahead of a court decision that will determine whether the firm can offer legal services in Arizona.

“The U.S. market is critical. At the end of the day—no matter how you slice or dice it—if the global legal services market is a trillion dollars of revenue, 50% of that sits in the U.S.,” said Fuller, who headed KPMG’s global legal services for more than five years and before that was head of KPMG Law for Australia and the Asia Pacific.

But KPMG does not intend to compete directly with U.S. law firms, Fuller said. Instead, it aims to focus its U.S. offering on legal managed services, which he said will differentiate it from law firms.
