The research for IFLR1000 United States 2020 will begin soon. If you are interested in participating in the research, please register below. We will send all registrants the guidelines for our 2020 research.




IFLR1000 researches and ranks law firms and lawyers on the basis of transactional advice. Each annual research process culminates in the publication of law firm rankings, individual lawyer ratings, and editorial content.

IFLR1000 United States ranks firms and lawyers in every US state in up to six practice areas, depending on the volume of mandates available*.

We asses firms and lawyers in six areas of work at state level:

• Banking
• Capital markets
• M&A
• Project development
• Real estate
• Restructuring and insolvency

*If we do not currently produce a ranking table for an area in the state where your firm is based, you can still provide us with a submission. We are consistently trying to expand our coverage and will produce ranking tables for any area we have sufficient evidence to.


IFLR1000 United States Awards

This year we will be running state level awards research in tandem with our ranking research. Any firm that participates in the ranking research will be considered for the awards. The award will ceremony take place in New York in September 2020.

The submission deadline for the awards and ranking research is: January 31, 2020


How to participate

Research methodology

Our law firm rankings and lawyer ratings are based on three key criteria:

Transactional evidence

In each research cycle we ask firms to provide transactional highlights from a designated period.

Transactional evidence is the decisive factor we use to determine a firm’s ranking. For a firm to be ranked, it must have a track record of advising on transactional work relevant to our ranking categories.

The same applies to the ratings of individuals; lawyers must have been working on significant deals in some capacity to be rated.

Primarily firms submit deals to us via the research form. Our research team also monitors daily deal news and updates to complement this.

We also analyse statistical evidence of transaction values and volumes produced by external publications.

Client feedback

We survey tens of thousands of corporate and in-house contacts provided to us participating firms, to get their opinions on the firms and lawyers they use.

Client feedback is used in support of transactional evidence when determining a firm’s ranking or lawyer’s rating. What this means is good feedback alone will not ensure a firm or lawyer is ranked or rated – a firm or individual must be experienced in advising on significant transactional work.

We ask for feedback on attributes including:

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

Peer feedback

We conduct an annual Lawyer Survey of lawyers to get their thoughts and feedback on their markets. All lawyers active in the relevant research categories are invited to take part.

We also conduct a significant number of phone and face-to-face interviews with practitioners, where we ask for feedback on firms.

Peer feedback is secondary to client feedback and we only take this type of feedback into account where it is supported by deal evidence.
