Kevin Sullivan

Partner, Head of Colchester Dispute Resolution Team

I am a partner and head of 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.

What our clients say

  • Thank you very much for getting back to me so quickly on this and with something that actually makes sense. How I wish all solicitors operated in the way you guys do.
  • 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.
  • Extremely prompt response, very practical and good commercial advice. Excellent value for money.Client testimonial from the Legal 500
  • The firm provides 'sensible and realistic advice' to its corporate clients and is routinely instructed on high-value and complex dispute claims.The Legal 500
  • Key lawyer Kevin Sullivan in Colchester is 'very straightforward and realistic'.The Legal 500
  • The Birkett Long team helped us in our claim for compensation from two UK banks over a period of more than 12 months. Their advice was sensible and cohesive, their fees very reasonable and ultimately they helped facilitate compensation awards totalling almost £100k via the Financial Ombudsman.
  • Your handling of this case has been exemplary.
  • I was lucky enough to instruct Birkett Long on a very involved case in which Kevin Sullivan dealt with on my behalf and I have to say he did an absolutely amazing job and was probably the most helpful solicitor I have ever dealt with.
  • I would like to thank you and your team for all your advice and help with my case. I appreciate your understanding and care with this delicate matter for me.
  • This is a team of professional and friendly partners and staff that take time to understand your specific requirements and tailor the advice.Client testimonial from the Legal 500
  • A big thankyou to yourself and Molly and your team. A large weight has just been lifted off my shoulders.
  • Thanks again for all your help - really, really appreciated.
  • Kevin Sullivan is a fantastic lawyer who has guided me through some very difficult decisions and still continues to do so.Client testimonial from the Legal 500
  • I've dealt with many, many lawyers - often paying fortunes in the City. Trust me - for 'conflict resolution' Kevin's just as effective, easier to deal with and far better value.
