Attorneys with mega-firm Dentons are under fire on two fronts stemming from their representation of former Sutherland partner Bennett Kight over allegations that he spent years draining millions of dollars from trust funds he managed for a longtime Sutherland client.

A federal magistrate judge in Atlanta has ordered Kight to undergo a mental competency exam after Kight’s Dentons counsel—Atlanta attorney Barry Armstrong and Chicago lawyer Rachel Cannon—claimed the 76-year-old Kight was suffering from dementia triggered by a 2008 brain hemorrhage and is no longer capable of assisting in his defense against federal fraud charges.
