What is a Magic Circle Firm?

A Magic Circle law firm is a company traditionally seen as one of the leading five in the UK. It’s an informal term based on a combination of turnover and profit to group the biggest law firms at the time the phrase ‘magic circle’ was coined.

The first 4 of the names above are among the 10 largest law firms in the world, while Slaughter & May were deemed one of the magic circle lawyers by virtue of their high profit per partner, despite being a much smaller outfit than the other 4 – in fact, they have the highest profit per equity partner of the group as measured in 2017.


Who are the Magic Circle Law Firms?

Below is a mini-profile of each of the Magic Circle law firms, shown in order of 2018/19 turnover:

Clifford Chance

The history of Clifford Chance can be traced back to Anthony Brown’s company formed in 1802 – a firm that later came to be known as Coward Chance. Another relatively small firm of solicitors, Clifford Turner was formed in 1900 and both these firms did well in terms of longevity. But it was not until their merger in 1987 and the formation of Clifford Chance that a major legal presence in the UK and worldwide became known.

Clifford Chance has since expanded worldwide and was the first notable law firm from outside the USA to practise US law. Since 2005, it has opened new offices in Japan, India, Africa and Australia.

This roots of this major international law firm were founded in 1838 when John Linklater formed a partnership with Julian Dods. The company known as Dods & Linklater later changed its name to Linklater & Co, and a subsequent merger formed Linklaters & Paines. Following several European mergers between 1990 and 1999, the company settled on the name Linklaters.
