Athena Markides

Call 2011

"Very bright, extremely conscientious and hardworking; she picks up issues and absorbs large volumes of information quickly and provides accurate, timely advice."
(Legal 500, 2021)

Athena Markides practises in all of Chambers’ core areas of work and has particular expertise in insurance, commercial litigation, construction and property damage. She has a particular interest in work with an international dimension.

Athena has considerable advocacy experience, regularly attending trials and interlocutory hearings on all three tracks and in the High Court and county courts across the country. This has enhanced her drafting skills and enables her to advise on tactics and merits swiftly and succinctly where required.

As Chair of the Young Bar in 2019, Athena was instrumental in negotiations with the Ministry of Justice and Crown Prosecution Service, securing the first pay rise for prosecuting counsel in eighteen years and thereby avoiding strike action by criminal practitioners. She also wrote and spoke widely about the key issues of the day (including Brexit, wellbeing and virtual hearings) and was a keynote speaker at the Annual Bar Conference, addressing delegates on the meaning of justice and the metrics by which it could be measured.

Before coming to the Bar, Athena gained valuable experience undertaking in-house work. Between 2012 and 2013, she worked at a start-up providing online invoice discounting services (the first of its kind in Europe). As such, she is confident undertaking work involving complex financial products and facilities and collections operations. Working with institutional investors and with SMEs also honed Athena’s understanding of the needs of corporate clients and how best to deliver for them.

Between 2011 and 2012, Athena gained experience of the telecoms industry and related regulatory, public law and competition law issues through her work as a paralegal at the Office of Communications (Ofcom). She undertook a wide variety of work including advising upon competition and procurement disputes and judicial reviews and also drafted documents for the Leveson Inquiry. She worked with people at all levels of seniority and across Ofcom’s departments, and continues to enjoy working as part of a team as well as individually.

Athena welcomes instructions from solicitors, in-house legal departments and qualified foreign lawyers.

Insurance & Reinsurance

Athena has extensive experience in insurance matters. She has advised, drafted pleadings and represented parties in coverage disputes as well as professional liability and recovery proceedings.

Most recently, she has advised and acted for parties in relation to coverage issues arising from the Covid-19 pandemic. As such, she is very familiar with both the relevant legislation and the science in this area.

She has also advised and acted for parties in claims involving Consumer Insurance (Disclosure and Representations) Act 2012 and the 2015 Insurance Act, as well as in pre-Insurance Act claims involving material misrepresentation, non-disclosure, moral hazard, fraud, fraudulent device, breach of contract and dual coverage.

Athena spent a year on part-time secondment to a leading London insurance firm, where she worked closely with a team of solicitors on high value and international insurance matters, negotiations and claims involving coverage and recovery elements. This reinforced Athena’s understanding of the needs of her instructing solicitors and of their clients and how best to deliver for both.
