U.S. law firms are poised to close 2020 with better-than-expected results, with a large share of big firms increasing their revenues in spite of massive challenges from the COVID-19 pandemic, according to survey results released Wednesday by Wells Fargo Private Bank.

About 72% of the 120 firms surveyed by the bank increased their revenues so far in 2020, according to the results. Look closer, and there’s evidence of a steadily growing gap between the haves and the have-nots.
