Mark specialises in crime, business crime, confiscation, asset forfeiture & recovery cases.


Mark Cotter Q.C. took silk in 2017, following a highly successful career as a junior specialising in serious and heavy crime (both for the prosecution and the defence).  He undertakes a significant amount of private work and has, for many years, been ranked in Chambers and Partners as a leader in the field of crime at the London Bar. 

Mark is a specialist in the field of criminal defence and has extensive experience in all areas of criminal work, from murder to money laundering. His particular areas of expertise include acting in cases involving homicide, fraud and serious sexual offending.  Prior to taking silk, Mark led in numerous heavy fraud cases, multi-handed conspiracies and cases involving the most serious sexual offences.  He has extensive experience of prosecuting and defending intelligence-led operations that raise difficult issues relating to disclosure and public interest immunity.

Mark is also experienced in cases involving regulatory and disciplinary issues and has significant experience of acting and advising in cases of Judicial Review.

In addition to maintaining a high-end defence practice Mark was, at the time of taking silk, admitted to the CPS list at the highest grade (Grade 4) and the Serious Fraud Office list at the highest grade (the ‘A’ list).  Mark has extensive experience of prosecuting cases involving serious violence and homicide, allegations of conspiracy and substantial and complex fraud.  This includes dealing with cases raising highly complex disclosure issues, including the most sensitive of intelligence material.

Mark accepts direct public access instructions in suitable cases. He is often instructed to advise on referrals to the Criminal Cases Review Commission (CCRC), or out of time appeals to the Court of Appeal (Criminal Division).


Mark was called to the Bar in 1994.
Mark took Silk in 2017.

Mark Cotter QC5 St Andrews HillHas grown as a relatively new QC into 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.
