Sutherland, Asbill & Brennan’s proposed merger with U.K. firm Eversheds would cause another big shift in Atlanta’s evolving law firm landscape, leaving only a few legacy Atlanta firms that have resisted the trend to merge.

If the two firms’ partners approve the combination, announced Nov. 29, there will be only three big Atlanta-based legacy firms left that haven’t undergone any mergers, acquisitions or name changes: King & Spalding, Arnall Golden Gregory and Morris Manning & Martin.
