Mark Side was born in England and studied Philosophy, Politics and Economics at Oxford University. Mark is a commercial litigation solicitor and mediator.

Mark was admitted as a solicitor in England and Wales in 1986 and worked in the City of London before moving to Hong Kong in 1992.

After qualifying as a solicitor in Hong Kong, Mark worked at two City of London international law firms. Before joining Tanner De Witt in 2000, Mark headed the litigation department of one of Hong Kong’s largest law firms.

Mark has conducted one of the largest cases in Hong Kong concerning the extent of a barrister’s professional duty, which generated litigation in Hong Kong, England and various courts in the United States of America. For a number of years Mark conducted litigation in Hong Kong for a major Chinese bank and handled cases concerning letters of credit and the extent of a banker’s duty of care to non-customers.

Mark has extensive commercial litigation experience in both the UK and Hong Kong and has worked on restrictive covenant cases involving departing partners of law firms. Mark acts for shareholders, main contractors, financial companies, public companies and accountants.

A part of Mark’s work is for the Law Society’s Solicitors Disciplinary Tribunal and the Disciplinary Committee of the Hong Kong Institute of Certified Public Accountants and involves the hearing of professional negligence complaints within these professions.

Mark and his team also advise on non-contentious matters such as on contract terms and employment matters, in particular on termination of employment contracts and on the enforceability of restrictive covenants.

Mark is a CEDR accredited mediator (see the website at www.CEDR.com) and understands the long-term consequences on individuals involved in family disputes. Mark encourages the use of less aggressive means to reach amicable agreements in family and divorce cases and is highly effective in pre-action settlement.
