Humphries Kerstetter LLP is a law firm based in the City of London specialising in high stakes commercial dispute resolution often with an international element.

We have a "reputation is everything" ethos. Accordingly, our approach is not targeted at maximising profits, but rather at the enhancement of the firm’s reputation. 

Our aim is to form lasting relationships with our clients who look to us whenever and wherever important commercial disputes arise.


We value our reputation above other considerations. Therefore, quality is our top priority.

We work on the basis that the smartest and most creative dispute resolution lawyers can offer the best solutions without the need for niche specialisations.

We focus on our clients’ commercial objectives and think creatively about how these can most directly be achieved through any available dispute resolution methods.

We take a very client-focused approach to service and cost designed to enhance this reputation for quality and value. Our rates are competitive and below what would need to be charged for the same level of service by larger London-based competitors. We will also consider alternative fee arrangements and third party funding where appropriate.

We have very broad expertise in many methods of dispute resolution including litigation, arbitration and mediation.

We have acted in many high profile reported court and arbitration cases but are also at home with the strategic and commercial planning that takes place long before, or in lieu of, a dispute reaching a court or tribunal.

We have particular experience in managing international disputes that might require foreign proceedings, arbitration in an international forum, the application of foreign law or the involvement of sovereign state parties.

Our partners have all come from London-based large international law firms. The firm was founded in 2009 by the Senior Partner, Mark Humphries, who was the Head of Advocacy at Linklaters LLP for over 15 years. His vision was to create a nimble "fighting force" that could offer clients the quality of a large firm litigation practice whilst operating free of conflicts, bureaucracy and extensive overhead cost.

Since our founding, we have grown to add other lawyers and advocates as well as lawyers who have trained at Humphries Kerstetter, all of whom share this vision and bring their own diverse experience.

We have a reputation for a proactive, commercial approach, focused staffing and an ability to boil a dispute down to its core issues of contention. The result is first class commercially-minded representation at a highly competitive cost.
