Get involved in our research

Law firms, consultancies and companies are welcome to contribute to our research process, either to suggest members of their organisation to be listed, or to offer their experience as a buyer of legal services or a market participant.

Client references

For any of our research reports, we would be delighted to consider nominations for any individuals who can be considered international leaders in their field. If you are putting forward an individual from your own firm, please provide us with the details of a small number of client references for them whom we can contact to provide a recommendation, prior to the month in which research for the practice area commences. This allows us sufficient time to add appropriate nominees to our preliminary lists for circulation during research.

Please note that there is no longer a limit on the number of client references you may submit, but we suggest around 5-10 per practitioner.

Referees should be provided using the relevant online Client Referee Upload Tool

Work highlights

To enable us to best assess practitioners in our research, we are now inviting nominees (or their firms on their behalf) to provide details of recent work they have been involved in to support their nomination.

This will be used to enhance the existing information we collect from our peer-review research processes. Please ensure that any confidential information is clearly marked. Instructions are given on how to do this within the survey. This research will primarily be used in our decision-making process and non-confidential information from these deals may appear in our editorials.
