A law firm network (law firm association or legal network) is a membership organisation consisting of independent law firms. These networks are one type of professional services networks similar to networks found in the accounting profession. The common purpose is to expand the resources available to each member for providing services to their clients. The best known primarily law firm networks are Alliott Group (alliottgroup.net),Lex Mundi, WSG - World Services Group (multidisciplinary), TerraLex,Meritas (law), The Network of Trial Law Firms, Inc. (TRIAL.COM), the State Capital Group. and Pacific Rim Advisory Council The largest networks have more than 10,000 attorneys located in hundreds of offices worldwide.
The firms who are part of the networks may be formally or informally linked to one another depending upon the purpose of the network.
There were two distinct and different reasons for networks developing in the legal profession. The first was internationalization which became globalization in the 1990s. Law firms simply needed international connections. The second was expansion of a number of large United States firms to become “national”. Smaller firms or firms with a niche practice required this same expertise in other states. The networks provided them this expertise.
The internationalization of the legal profession began much later than in the accounting profession. There was no real need because, unlike accounting firms which conducted worldwide audits, law firms in each country were able to deal with client matters. This changed in 1949, when Baker & McKenzie began to expand to non-United States markets to assist U.S. clients that were expanding overseas following WWII.
Internationalization was slow to start because the legal profession was much more restrictive than accounting in allowing foreign firms to enter and practice in their countries. There were rules requiring that the names of the partners be present in the name of the firm. The forces of the international community converged in the late 1980s. U.S. and English firms began establishing branches in the primary commercial centers. This new competition in local markets had the immediate effect of forcing local firms to evaluate alternative ways of providing services to their international clients.
