Mark “identifies what he wants to achieve on behalf of the client and then takes the steps that need to be taken to do it.” “[He] is “at the very top of his game”; [clients] appreciate his “attention to detail and unswerving commitment to putting his clients in as strong a position as possible. ”

“Sources label Mark Hastings, a “terrific” civil fraud practitioner. He advises on challenging pieces of fraud litigation, often spanning multiple jurisdictions.” Similarly, “He is a very staunch litigator with an encyclopaedic knowledge of the law, who isn’t afraid to roll up his sleeves.”

“His real strengths are his devotion to the case and his good judgment,” while one particular client quote describes Mark’s approach well: “He is a very focused individual, who has great attention to detail. He has relentless determination and is a fearless litigator.”

Chambers UK
