Commercial Mediator


William (“Bill”) Marsh is one of the UK’s most experienced commercial mediators. Involved full-time in mediation since 1991, and independently rated by Chambers Directory as “…one of the greats…”, he has successfully mediated a wide cross-section of commercial disputes. International recognition has led Bill to be featured at the top of the most highly regarded individuals in the World list in The International Who’s Who of Commercial Mediation 2014. Operating both in the UK and internationally, his mediation practice has included disputes and parties from numerous countries including UK, Ireland, India,  Cayman Islands, France, Switzerland, Belgium, Spain, Italy, Greece, Lebanon, Tunisia, Nigeria, Ghana, USA, Canada, Australia, Japan, China, Russia, Ukraine, Uzbekistan, Bahrain, Qatar, Saudi Arabia, Egypt and South Africa.  Parties have included individuals, private companies and firms, public companies, public bodies/authorities, and national governments.  His mediations cover a broad cross-section of commercial disputes, and range from relatively modest to multi-billion pound in value.

Before becoming a mediator, Bill practised as a solicitor in the UK and Paris, handling international and domestic corporate and commercial matters (acquisitions and disposals, flotations, partnerships, commercial agreements, joint ventures, agency and distribution arrangements, insolvency, etc.).

He was for 11 years (until February 2002) Executive Director of CEDR.  He has also worked with some of the major ADR organisations in Australia, Hong Kong, Singapore, Netherlands, France, Austria, Russia, Slovakia, Romania, Bulgaria and Canada.
