Independent survey shows Chambers in the lead

International In-house Counsel, an independent journal, conducted a survey of over 20,000 in-house counsel from around the world.
They were asked:If you use directories to identify law firms / individuals, which do you use?

Their answers gave Chambers an astounding lead:

Chambers & Partners 51%
Legal 500 22%
Martindale-Hubbell 14%
Practical Law Company 7%
Who's Who Legal 6%

These figures reproduced from the International In-house Counsel Journal, an independent publication.

Our research


We rank both lawyers and law firms based on the research of 150 full-time editors and researchers employed at our head office in London.
We talk to lawyers and clients, conducting in-depth telephone interviews. Many of our researchers are multi-lingual. All are trained in the techniques of investigative research.

We also use information submitted by law firms but the most credible source of information is our in-depth face-to-face and telephone interviews. These give us the wide-ranging and testable information on which our rankings and commentary rely.

The client's guide


Our guides are trusted by clients throughout the world when they need to find reliable, capable and appropriate business lawyers.

"In a legal marketing world that is literally awash in gratuitous and duplicative listings, pay-for-plays, unresearched ratings, rankings and scams - over 900 at last count - there are innumerable ways for lawyers and marketing departments to waste their time and money. Amid the confusion and noise, there are only a few islands of sanity and dependability left. Among those, Chambers & Partners stands out for its comprehensive view of the marketplace, depth and quality of research, and commitment to reporting integrity. To be sure, there is time and effort involved in our commitment to Chambers, but this is work that both our attorneys and marketers undertake willingly because Chambers commands clout and credibility with key clients."
