Our research


The IFLR1000 is the guide to the world's leading financial and corporate law firms and lawyers. Our first rankings were published in 1990 and we currently research over 120 jurisdictions worldwide.

We produce:

  • Law firm and lawyer rankings categorised by practice area and jurisdiction
  • An online transaction database IFLR1000 DEAL DATA
  • Daily news and features including analysis of market trends and law firm news
  • Reviews of law firm performance, including practice area, sector and geographical strengths, client and peer feedback and examples of transactional work.

Research projects

The IFLR1000 research is a continuous process and our journalists keep abreast of major developments (notable transactions and law firm news) throughout the year.

If you have any relevant firm or deal news you wish us to consider for our research or online output please contact a member of our research team.

Our main research project is FINANCIAL AND CORPORATE which is published in October.

The research incorporates the following core practice areas:

  • Banking
  • Capital markets
  • M&A
  • Private equity
  • Project development
  • Project finance
  • Restructuring and insolvency

*In some jurisdictions we also research derivatives, financial services regulatory and investment funds.

For explanations of what work can be submitted for each practice area, please view our: PRACTICE AREA DEFINITIONS

Ranking criteria

Our law firm rankings are based on three key criteria:

Transactional evidence
In each research cycle we ask firms to provide transactional highlights from the previous 12 months.

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

Peer feedback
We conduct an online ‘LAWYER 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 conduct phone and face-to-face interviews with practitioners.

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:

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

Leading Lawyers and Notable Practitioners

Alongside our firm rankings we also recognise the work of outstanding individuals. Our recommendations are based on the same three factors as our law firm rankings and consist of the following categories:

Expert Consultant
Senior figures with name recognition who focus on consulting and building client relationships.

Market Leader
True leaders of their field, these lawyers have a track record of high profile innovative deals and are recognised as the standout performers in their country or practice area.

Highly Regarded
Lawyers who are highly regarded by their peers and possess a strong transactional record and positive client feedback.

Rising Star
'Ones to watch' these are lawyers who are building their reputations in the market.

We also recognise lawyers who have advised on one or more deals featured in IFLR1000 Deal Data. These are categorised as Notable Practitioners.

Annual research submissions

To supplement the information our researchers source from the market we ask law firms to submit an annual summary of their practice covering the previous 12 months, including transactional highlights, practice group developments and any recruitment or departures of legal staff.

We also ask firms to submit client referees, who we contact as part of our research to seek opinion on the performance of firms. Client referees must have worked with the firm in the 18 months prior to submission.


Submission guidelines

Firms may submit information for our annual research using our RESEARCH FORM.

The research begins in January each year.

The research form submission MUST include the following information:

  • Key individuals within each practice area team
  • Recruitment and departure of senior lawyers (partner or counsel level)
  • Other notable developments - panel appointments, industry award wins etc.
  • Examples of the firm’s key transactional work in the last 12 months prior to the submission. Transactions must have either been closed or had significant work completed on them in this time period.
  • Firms can submit a research form for each ranking category covered in each jurisdiction in which they are active.
  • Firms can submit information for more than one ranking category in the same form, for example Banking AND Capital markets or M&A AND Private equity.

Ranking categories

The specific ranking tables we produce for each jurisdiction are defined by the size and maturity of the market.
