About Iwan

After a career in industry Iwan Doull retrained as a lawyer.  He has been a partner in Berry Smith since 2003 and is the head of the firm’s highly regarded Dispute Resolution Team.

He deals with all aspects of Commercial Litigation, but has a particular specialisation in claims for Professional Negligence. Iwan is a member of the specialist Property Litigation Association, The Compulsory Purchase Association and ACTAPS (the organisation for contentious trust and probate lawyers). He is a regular speaker on all property related matters for the RICS across Wales and the Institute of Chartered Accountants.

Iwan has for many years been a top ranked lawyer in several areas of law in the Chambers and Partners Guide to the Legal Profession and is the only lawyer in Wales recognised in the Legal 500 Guide as a Leading Individual in 5 different areas of law.  Iwan believes that his non legal background enables him to provide more than merely legal advice, as is recognised again in both the Legal 500 and Chambers.
