Assurety is the UK's Band 1 specialist in witness familiarisation and preparation, helping litigation teams reduce the risks associated with witness evidence in high-stakes proceedings. We regularly support leading law firms including Freshfields, Quinn Emanuel, Clifford Chance, Herbert Smith Freehills Kramer, Slaughter and May, A&O Shearman, Baker McKenzie, Mishcon de Reya and Norton Rose Fulbright.
Every programme is tailored to the witness and combines advocacy from KCs and senior junior barristers with expertise from performance psychologists and communications specialists. Through realistic, ethical cross-examination practice, we strengthen witness confidence, credibility and performance under pressure without ever addressing the facts of the case.
