The U.K. Bribery Act set to take effect in 12 weeks will do more than present the opportunity for lawyers to advise clients on how the law interacts with the U.S. Foreign Corrupt Practices Act. It could force law firms to examine their own business practices when working in, or dealing with anyone from, the United Kingdom.

“It will have a fairly dramatic effect on law firms, both in the sense of them being law firms and in the sense of them being businesses that routinely entertain clients,” Duane Morris London-based partner Jonathan P. Armstrong said.
