Kevin Sullivan


I am a partner in our Colchester Dispute Resolution Team. I am a specialist in the field of contentious insolvency law with nearly 20 years’ experience in general dispute resolution practice. I am based in our Colchester office, and am available for a free 15 minute chat over the phone on 01206 217376.

In addition to handling substantial contract, company and shareholder disputes, I act for insolvency practitioners as well as in connection with contentious recovery actions – typically involving misfeasance/breach of duty, wrongful trading, transactions at an undervalue, preferences and unlawful dividends. 

I advise companies and directors as well as debtors/bankrupt and their spouses/partners in relation to a wide variety of corporate and personal insolvency-related issues. 

I have a particular interest in the defence of proceedings brought under the Company Directors Disqualification Act 1986.

I am a mentor to several colleagues. I have successfully passed the Certificate of Proficiency in Insolvency examination and I am an Associate member of R3 (the Association of Business Recovery Professionals).

In my spare time, I help fundraise for a local hospice as well as volunteering at running events. I produce, present and buy a lot of music (particularly electronic). I regularly play football, enjoy running as well as cycling and I am a keen skier having lived and worked in the French Alps before qualifying.

The Legal 500 – The Clients Guide to Law Firms

What our clients say

  • As a director of an SME, I was concerned at advice and assistance offered by the Company's advisors both for my duties as a director and for courses of action to be taken as the company struggled to recover from a major reduction in revenue and work for a Local Authority, and an arson attack on the company. I sought help at Birkett Long, was given clear and timely advice, and put in touch with relevant financial advisors, allowing the sale of the company. When the company subsequently failed within three years, I continued to receive sound advice in relation to the Administration. I would seek advice from Birkett Long again.
  • My wife and I are really thankful for everything you and Kevin Sullivan have done for us during this difficult time. We have had some very dark days over this and you have always managed to keep us level and confident that we would eventually escape their clutches. a client who was involved in a dispute with a bridging finance company
