IFLR 1000
The Guide to the World's Leading Financial Law Firms

About 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:
• Annual law firm and lawyer rankings categorised by practice area and jurisdiction

• A directory of firms and lawyers active in financial and corporate work

• 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.

The new and improved IFLR1000.com will be live from May 2014.

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 news you wish us to consider for our research please contact a member of our RESEARCH TEAM.

We currently have two specific research projects, which culminate in the publication of law firm rankings. 

ENERGY AND INFRASTRUCTURE (select jurisdictions only) - Published May


Ranking criteria

Our law firm rankings are based on three key criteria:

Transactional evidence
We ask all firms to provide transactional 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 Ranking 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 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.

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

Leading lawyers and rising stars

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.

Leading lawyers
These are individuals who have proved themselves to be among the leading figures in their respective markets. As well as receiving recommendations from clients and peers these individuals will also have a clear track record of innovative work.

Rising stars
These are individuals considered by the market to be the ‘Leading lawyers’ of the future. Often more junior members of the firm they will have demonstrated their skills and potential by already advising on innovative transactions.

Annual research submissions

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

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


The deadlines for submissions for our two major research projects are outlined below: 



Submission guidelines

• Firms may submit information using our submission templates available for download below.

• If preferred, firms may also submit their annual summary information in either text (Microsoft Word or equivalent) or PDF format.

Client referees should be submitted in a spreadsheet (Excel or equivalent). 

The annual summary 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 or case work in the last 12 months prior to the submission. Transactions or cases must have either been closed or had significant work completed on them in this time period.
• In the areas of M&A and project finance, firms may highlight their work on a tender or bidding process even if that process was ultimately unsuccessful.

• Firms can submit an annual summary for each ranking category covered in each jurisdiction in which they are active (please see below).

• Firms can submit in jurisdictions where they do not have an office however please note that if the firm does not practice local law it will only be eligible for inclusion in our International firms category in that jurisdiction.

International firms may make a submission for an entire region if they are active in it but do not have offices there. For example Latin America or Africa , however, the same restrictions defined above apply.

• 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.

In the smallest or least developed jurisdictions we produce a broad ENERGY AND INFRASTRUCTURE or  FINANCIAL AND CORPORATE ranking.

The IFLR1000 research covers the following broad categories:

• Disputes
• Corporate
• Finance
• Projects development
• Public law

• Banking and finance
• Capital markets
• Competition
• Financial services regulatory
• Investment funds
• Mergers and acquisitions and private equity
• Restructuring and insolvency 

Transaction classification
Below is a guide to how we classify different forms of financial and corporate work. If there is not a separate ranking table in your jurisdiction for a type of work it will be considered in the research as part of one of the broader categories above it.

To see which ranking categories we cover in your jurisdiction in our  financial and corporate research, please refer to the guide below:
