CONSULTING has its Big Three; accounting the Big Four; and executive search a Big Five. But there is no corresponding clutch of dominant law firms. None has amassed as much as 0.5% of an industry with global revenues of around $650 billion a year. Even the biggest law firms may be anachronistically inefficient. They are run by lawyers, not professional managers, insist on charging by the “billable hour” rather than by results and use little technology more advanced than e-mail. Nonetheless, most big law firms have continued to be highly profitable.
In recent years, clients have begun to rebel against the billable hour, and at being charged senior lawyers’ rates for work done by juniors. Some have started sending basic legal paperwork to cheap, offshore processing centres. But only now is a serious threat to the law firms’ cosy existence emerging.
It comes from none other than the Big Four accounting networks (Deloitte, EY, KPMG and PwC), whose combined annual revenues of $120 billion exceed the $89 billion generated by the 100 largest law firms combined (see charts). Having already dipped a toe into the legal business a couple of decades ago, only to retreat, the accountants have been stealthily building up legal-services divisions. These have now reached a size where they outgun most law firms: by headcount, PwC’s legal arm is the world’s tenth-biggest, and all four networks’ law divisions are in the top 40 by this measure.
