"This was one of those cases where settling seemed an impossibility at the start of the day, but still a deal was done. Very many thanks to Richard for his unfailingly calm, polite, friendly manner. He was completely unflappable and I felt that he was completely committed to getting the job done and helping the parties to get a result. I wouldn't hesitate to recommend him and to instruct him again."

"Thank you so much for all your hard work on Friday.  It was a skilful performance!  Client is very grateful for a settlement, as am I, and I am further grateful to you for picking it all up so late in the day, and for working so late into the evening for it." (Solicitor in a Property Development/ Construction/ Partnership Dispute)

"Our case was a very unpleasant family fall out that had progressed to a legal claim by my father against me and my wife, so things were very tense. There had been tentative prior negotiations carried out, and both sides had entrenched positions, so it looked impossible to resolve things without progressing the claim to court. Richard was a breath of fresh air on the day: good humoured and full of helpful suggestions. He skillfully guided us to an agreed settlement by the close of play, which we were all grateful for. I was very impressed indeed by Richard"
