With hopes of gaining business from banking powerhouses in Charlotte, N.C., several big law firms have opened offices there in the past year. But a downturn in finance work has some of those shops rethinking their strategies.

In the past year alone, five law firms on the NLJ 250, The National Law Journal‘s 2007 ranking of the nation’s 250 largest law firms, have launched practices in Charlotte, home to Bank of America Corp.; Wachovia Corp.; Lowe’s Cos. Inc.; and several other Fortune 500 companies.
