Who we are

The number one provider Chambers and Partners

Assurety was set up in 2012 by Paul Epstein QC, Jason Galbraith-Marten QC and Ed Williams QC. Between them they have over seventy-five years of experience of cross-examining witnesses and arguing cases in the highest courts.

They established the business after realising from their time in court that not enough was being done to prepare witnesses effectively for the real experience of being cross-examined.



“Assurety are absolutely excellent. We have used them for a number of cases with great success. They have a strong team who quickly build a rapport with the witnesses and help build confidence in a sensitive way.” Chambers and Partners 2020

Together they developed a range of witness familiarisation courses that combine the skills and experience of leading barristers with expert communications trainers, to deliver the most effective preparation for cross-examination and to help participants to give their evidence to the best of their ability.

They quickly established Assurety as the acknowledged leader in premium witness training, and are now the only band 1 ranked firm in Chambers and Partners, helping numerous clients in weighty and high-profile matters, as well as offering clients premium communications training.
