Our rankings are based on the following key criteria:

Transactional evidence
We ask all firms and individuals to provide transactional highlights from their last 12 months of work.

We also analyse statistical evidence of transaction value and volumes provided by other market survey providers.


Client feedback
We speak to a wide range of corporate and in-house contacts as part of our client feedback survey to get their opinions on the firms and lawyers they use.


Peer feedback
No one knows more about the legal market than those professionals who work in it. We conduct a feedback survey of law firm partners and associates to get their thoughts and feedback on our current law firm rankings and leading lawyers.

All partners active in financial and corporate work are invited to take part and we also speak to a great number of practitioners through phone and face-to-face interviews.


We also ask for feedback on the following attributes:

Technical ability
Accessibility and communication
Depth of team
Value for money
Client/lawyer relationship
International network
