Womble Carlyle Sandridge & Rice is set to combine with its U.K. alliance partner Bond Dickinson to form Womble Bond Dickinson.

The two firms formed an alliance in June 2016 but have now taken this relationship a step further, although stopping short of full financial integration.

The union will go live in October under a company limited by guarantee structure, with the combined firm housing more than 420 partners and 1,000 lawyers across 15 U.S. offices and eight U.K. offices.
