Iwan Doull

Partner and Head of Dispute Resolution

About Iwan

Iwan heads up the highly regarded Dispute Resolution Department at Berry Smith and deals with all aspects of Commercial Litigation.

He is the only lawyer in Wales who is recognised as a leading partner, or is top ranked, in 4 different areas of law in both the Legal 500 and Chambers and Partners Independent Guides to the Legal Profession. The Legal 500 has placed him in the highest ranking “Hall of Fame” category for Commercial Litigation.

Prior to re-training as a lawyer, Iwan worked in industry and believes that his non legal background enables him to provide more than merely legal advice, something that is also reflected in client feedback in both the Legal 500 and Chambers and Partners.

What people say about Iwan

Iwan is the only lawyer in Wales recommended in the Legal 500 Independent Guide to the Legal Profession in five different areas of law, which describes him as a “leader in the field” and an “excellent litigator”.

“Where other solicitors have taken things at face value, Iwan took the time to fully understand the case, thought outside the box, and came up with a plan of attack. He kept us fully informed at all times.
He was not afraid to be honest, and told us when things were not likely to go our way, instead of the usual ‘tell them what they want to hear.”
We only wish Iwan was on our team from the beginning of this case, instead of only meeting him when we had to issue proceedings against our own solicitor!

“Iwan Doull has an established commercial disputes practice and remains a popular choice amongst insurance companies. Clients appreciate that his advice is “always factual and straight to the point,” and characterise him as a “a very bright individual with a very good grasp of complex matters.”

“Iwan Doull is widely known for his work in property-related claims. A market commentator says: “He puts clients at ease and explains things clearly and simply. I would certainly recommend his services.”

“I just wanted to let you know how much I appreciate all the effort you put into the case and thank you for making me feel at ease with the whole process. I am extremely impressed with the knowledge, professionalism and confidence in operating that you displayed it was actually a pleasure to watch you work.”

“Iwan Doull is a litigator anyone would be feel blessed to have in their corner. He has bags of pragmatism and a first-rate legal brain.”

“Iwan provided outstanding support and advice throughout.”

“Iwan Doull has an in-depth knowledge of commercial matters which he is able to communicate with clarity and patience.”

“He’s a brilliant lawyer who cuts through complex issues with apparent ease and communicates clear and accessible advice.”

“When Iwan assesses the prospects of a case, his considerations include aspects that others may dismiss and he is able to make recommendations based on evidence to support those considerations.”
