For 27 years IFLR1000 – the guide to the world’s leading financial law firms - has produced rankings and market intelligence for lawyers working in financial law globally. Last year’s research saw submissions from 2,500 of the world’s top law firms.

Now for the first time we are compiling rankings of law firms and lawyers for each of the 50 US states and the District of Columbia.

The research is now underway and we invite all relevant law firms to participate in the process.

The research process culminates in the publication of law firm rankings, individual lawyer recommendations and law firm reviews (IFLR1000 Reviews).

Nationwide vs state level research – How does it work?

IFLR1000 has researched the United States market since 1989 at a nationwide level. This year marks the first time we will be looking at the financial and corporate law markets at state level.

If you are a nationwide law firm you can participate in both research rounds. For the nationwide research you can simply send an update to the state submissions including international cross-border work.

Our nationwide research in the United States will continue and will take place during our main research period.

What deals should be submitted?

For each state you should submit case studies of financial and corporate deals that have been executed by attorneys based within that state.*

Deals involving two or more states can be submitted in each individual state submission.

International cross border deals should be submitted during the nationwide research (please see above).

You can submit any deals on which the firm has started work or completed since January 1 2017.

*Language emended on January 19th to clarify methodology based on questions.

Our law firm rankings are based on three key criteria:

Deal evidence

We ask all firms to provide deal highlights from their last 12 months of work.

We also analyse statistical evidence of transaction values and volumes provided by market survey title Dealogic.

Peer feedback 

No one knows more about the legal market than those professionals who work in it. 

We conduct an online Lawyer feedback survey of law firm partners to get their thoughts and feedback on our current law firm rankings and leading lawyers.

All partners active in the relevant research categories are invited to take part and we also speak to a great number of practitioners through phone and face-to-face interviews.

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.

We ask for feedback on the following attributes:

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