WWL Ranking: Recommended

Peers and clients say:

"Tony is a highly respected and stellar mediator"
"I would absolutely recommend him without reservation"


Born, educated, trained (LLB) and initially practising in New Zealand, Tony has lived in London since 1970 when he joined Coward Chance, later Clifford Chance where he was a litigation partner from 1973 to 1998 apart from a period as a full time managing partner between 1987 and 1990. He ultimately led the litigation practice in some of the most complex international litigation seen in the English and other courts. An early adopter of mediation for clients, he took the inaugural CEDR training course led by Professor Eric Green from Boston and Professor Karl Mackie and first mediated professionally in 1991.

Tony was an early member of the International Academy of Mediators where he is a Distinguished Fellow. He is also a Fellow of the Chartered Institute of Mediators.

In 1998, Tony was the first UK Lawyer to start practising as a full time independent professional mediator in civil and commercial matters. Since then he has dealt with a host of commercial matters of all types, many multi-party involving sums at stake up to US$1.2 billion. He has mediated in many jurisdictions including New York, Canada, Hong Kong, Ireland, elsewhere in Europe, the Bahamas, the UAE, Jersey, Guernsey the Cayman Islands and others.

In 2004, he joined Brick Court Chambers where he continues his practice.

For several years, Tony Willis has been recognised by all the independent legal directories as being at the top of his field. He won the 2012, 2013, 2014, 2015 and 2016 Who’s Who Legal awards for Global Commercial Mediator of the Year. He usually mediates alone but has co-mediated with other top ranked mediators in the UK and US. He has regularly mediated cases involving multiple parties.

Cases dealt with have covered almost all civil and commercial categories including banking and finance, contract, professional negligence, engineering and construction, insurance and reinsurance, insolvency, pensions, boardroom and partnership disputes, regulatory and competition cases. More recently he has mediated using virtual platforms such as Zoom and Teams.

Tony Willis is a citizen of the UK and New Zealand. He is married with five daughters and one son and lives in London and Hampshire. He retains strong links to New Zealand where three of his daughters live.
