For 29 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.

The first edition of IFLR1000 US was released this past summer, and now marks the beginning of the research process for the second edition of our law firm and lawyer rankings 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.

Submitted deals are also eligible for inclusion on our Deal Data feature.




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 second 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, 2018.

Why participate?

Actively engaging with our research team ensures:

  • Editorial coverage in the guide*
  • Accurate and in-depth representation of your firm’s activities
  • Potential market endorsement in a well-established, highly-regarded independent guide
  • Exposure to our audience of in-house counsel at the world’s most significant corporations and financial institutions, and private practice lawyers

*Our editorial policy dictates that all firms which participate in the research and provide relevant examples of transactional work are guaranteed editorial coverage



Our law firm rankings are based on three key criteria:

  • Transactional evidence

We ask all firms to provide recent transactional highlights and evaluate the complexity and significance of the work and the roles firms had on the deals. Complexity of work and track record of advising on complex deals are our primary considerations when determining firms’ rankings.

  • Client feedback 

We survey a wide range of corporate and in-house contacts to get their opinions on the firms and lawyers they use. Client feedback is the second most important factor for us when determining a firm's ranking. Positive client feedback alone does not ensure a firm will be ranked; clients should be providing feedback on recent work (within the current and previous calendar years) applicable to our ranking tables for it to be relevant and impactful on firms' rankings.

  • Peer feedback 

We conduct an online Lawyer Survey of senior private practice lawyers working in relevant areas to get their feedback on the market. We only use peer feedback as a guide and only take comments into consideration where they are supported by deal evidence, or a lack of it.


Notes on the research

  • Firms are not required to use the IFLR1000 submission template, firms can submit using alternative formats providing the information requested on the IFLR1000 research form is included.
  • Please mark confidential information in RED.
  • All client referees will be contacted.
  • All client referee information will be treated as CONFIDENTIAL and not published.
  • You can send us additional deals at any point during the year for consideration for IFLR1000 Deal Data. Deal Data is a database of financial and corporate legal transactions updated daily to complement our existing research and rankings.


Frequently Asked Questions

Can I submit information in a different format?

Certainly, as long as the relevant information is provided in a well-organized format.

What distinguishes IFLR1000 US from similar guides?

IFLR1000 US focuses exclusively on financial and corporate practice areas. Additionally, unlike some other guides we have a team of US-based researchers who are in the best position to analyze the US legal market at the state level.

Why should we submit?

Sending submissions makes the strongest possible case for your firm’s inclusion in the rankings. Firms who submit are also guaranteed editorial coverage.

Is IFLR1000 US “pay-to-play”?

No. Our editorial coverage is independent and all firms who submit receive the same consideration and guarantee of editorial coverage.

We’re a smaller, local firm - is it worthwhile for us to send a submission?

Yes. Although our publication includes many of the largest national firms, the US Guide’s rankings are made at the state level, which means there is plenty of opportunity for firms to be recognized that are based outside of main US financial centers such as New York, San Francisco and Chicago.
