Mark Cotter KC (Door Tenant)


Name: Mark Cotter KC (Door Tenant)
Position: Barrister
Year of Call: 1994

Mark took silk in 2017, having excelled in both prosecution and defence in high-profile and complex crime, with an emphasis on homicide and sexual allegations. He has, for many years, been ranked in Chambers and Partners and the Legal 500 as a leader in the field of crime at the London Bar. Mark also specialises in business and financial crime, including bribery, corruption, asset recovery and confiscation.

Known for his work ethic, case theory and relentless attention to detail, Mark has all the requisite qualities making him an approachable and contemporary KC. He is an excellent communicator and a master with juries, able to turn his hand to the most complex cases, as well as those where significant reputational issues are at stake.

In the field of homicide Mark has experience of defending in cases involving joint enterprise and young or otherwise vulnerable defendants. Mark recently secured the only across-the-board acquittal in a multi-handed knife murder where Mark’s client was only 14 years of age.  Immediately afterwards, he successfully prosecuted a multi-handed knife murder, securing across the board convictions, and then went straight into defending the lead defendant in another multi-handed knife murder where a ‘cut throat’ defence was being run.  Mark’s client (the lead defendant) was acquitted of both murder and manslaughter.  This back-to-back sequence, from late 2018 and into 2019, demonstrates Mark’s exceptional ability to successfully bring his skills to both the defence and the prosecution in cases of homicide.

‘‘An absolute foundation for any high-profile or complex criminal case. Throws everything into the case, and it consumes him for that period. He is easy to work with and is excellent on his feet, with jurors, judge and opponent. I have seen juries eat from his palm.’ – Legal 500 2021
