Megafirms" or BiglawEdit
The largest law firms have more than 1,000 lawyers. These firms, often colloquially called "megafirms" or "biglaw", generally have offices on several continents, bill US$750 per hour or higher, and have a high ratio of support staff per attorney.[17][18] Because of the localized and regional nature of firms, the relative size of a firm varies.[19]
