The upcoming union of Denton Wilde Sapte and Sonnenschein offers two firms that have suffered their fair share of setbacks a chance to reinvent themselves for the global legal market. Sofia Lind and Alex Novarese ask if the deal can help the pair to galvanize their businesses

Ten years ago, in a very different market, the newly-merged Denton Wilde Sapte spoke openly of its ambition to swiftly secure a US merger. And why not? The combined practice had scale, vision and was made up of two City firms with proud histories. It also had a sizeable Asian network and a seven-member European alliance, Denton International. Step forward 10 years and the firm has belatedly made good on that promise, announcing on 26 May a deal to merge with top 100 US practice Sonnenschein Nath & Rosenthal.
