Jon Lang Mediation

Listed in the first tier of mediator rankings of both the Chambers & Partners and Legal 500 directories (and in The International Who’s Who of Commercial Mediators), Jon is recognised as one of the busiest and most experienced mediators practising in the commercial field. CEDR accredited, Jon became a full-time mediator in May 2005, having spent almost twenty years as a solicitor in private practice, the last six as a partner in the disputes group of White & Case in London. Jon has acted as an expert in mediation, is a past Chair of the Mediation Committee of the International Bar Association and a member of CPR’s Panel of Distinguished Neutrals.


Areas of Practice

Jon is instructed in a wide variety of disputes both in the UK and overseas, from multi-party international trade cases involving proceedings in various jurisdictions to cases involving multiple and diverse claims between members of partnerships. Many of Jon’s cases increasingly require a significant element of ‘process design’ beyond the norm, and he is always very pleased to assist in developing the process best suited to the parties and dispute being mediated. Representative examples of cases by practice area can be found using the link below, but Jon would be more than happy to provide further case examples in specific areas if that were thought helpful.



With twenty years litigation practice behind him, Jon draws on his extensive experience not just of mediating several hundred cases, but of negotiating settlements on behalf of his clients and representing them at mediation whilst in private practice. He has a calm and measured approach and works hard with the parties to reach a deal.

A selection of comments from recent editions of the Chambers & Partners and Legal 500 directories reflecting Jon’s mediation style and practice can be found using the link below. These directory comments are followed by examples of feedback received direct from parties and those that represent them.

Client Guide to Mediation

I was asked recently by a solicitor whether I had a brief guide to the mediation day that he could pass on to his clients. I didn’t, but I have now! It is entitled, simply, ‘Client Guide to Mediation’. Please feel free to download and send it to any clients who might find it useful.
