Feedback on James:

"I was very impressed with your preparation, even-handed approach, skills in terms of bringing forward the important issues, and, in the latter half of the mediation, using your knowledge to be devil’s advocate and “reality check” the positions of all the participants. Congratulations in facilitating an agreement in the time allocated which all participants appeared to find satisfactory."

"James' understanding was excellent, as was his communication, his comments were concise and given with clairty."

"He tested the cases very well and kept good pace."

I thought the service you provided was excellent, very professional and reasonably priced. You were polite and courteous at all times and I could tell you had a real “feel” about the case considering that you hadn’t had the papers for very long. I have already recommended you to my principal and colleagues. I have to admit to going into that mediation convinced that a settlement would not be reached given the difficulties I had arranging it with the other side.” [Mediation did settle]

I am totally satisfied with the professional service delivered by James Tumbridge.  ... It was very clear that James had read and understood the information provided to him.  This resulted in a fair outcome to both parties. I personally felt confident that I had every opportunity to state my case. It was reassuring to know that James, with his wealth of experience in his field was able to provide examples of how Court decisions are reached.  This helped focus our minds in terms of avoiding unnecessary and costly litigation by helping us to understand the rationale behind the decision making process involved. I would urge anyone who is contemplating a direct route to Court, to think again.  For a modest fee, both individually and as a couple we have saved thousands of pounds by using this professional service.”

"Mediation can be a stressful experience, but we found on the day that [Mr. Tumbridge] put us at our ease and explained exactly what mediation entailed. This helped us to understand what was required for it to be successful."

"We felt that you were neutral, approachable and trustworthy and that you brokered a deal that was in the best interests of both parties with the information that was available to you. You showed your commitment and determination to conclude this matter and you did not give up when negotiations became difficult, you stayed until the matter was finally concluded bringing an end to all the stress and worry we had endured over the past 2 years.  We are grateful for your efforts on the day and although we hope never to need your services again, we would defiantly use mediation in the future as a form of resolving a dispute."

I thought [James’] handling of the situation was excellent, communication was very clear and [his] grasp of the key issues was great, especially given the short preparation time.”

"...James is engaging, intelligent and entusatic as a person, hardworking expert and sesible as a lawyer..." - Lord Neuberger Retired Supreme Court President, 2017
