Associate Member

Following a successful career at the Bar (where he practised at 11 New Square, Lincoln’s Inn) Jonathan Winegarten became the first barrister Chancery Master. In 1998 he was appointed Chief Master of the Senior (formerly Supreme) Court, Chancery Division. After his retirement as Chief Master in July 2013 he returned to 11 New Square - now Radcliffe Chambers – to take up his new career as a mediator. He said: “Having spent much of my time as Master and Chief Master urging parties to mediate rather than litigate it is time now to practise what I have for so long preached.”

He was accredited as a Civil and Commercial Mediator by the ADR Group in November 2013, since when he has built an enviable reputation as a skilled and successful mediator.  His mediation style is noted for his clear-thinking, good knowledge of law and procedure, courtesy and good humour. He quickly puts parties at their ease, displaying the same qualities of fair mindedness and a pleasant manner that earned him high regard with colleagues and clients during his time at the Bar and on the Bench.

He is experienced in dealing with all manner of disputes that come to the Chancery Division, including those relating to trusts, settlements, wills and probate, Inheritance Act claims, partnership cases, professional negligence actions, revenue matters, company and commercial claims, copyright, passing off and other intellectual property cases, landlord and tenant matters, conveyancing and all types of land law litigation.

Among the comments received:

“By all accounts my clients were very impressed with Jonathan they thought he managed the case with insight and with the utmost professionalism”.

“Jonathan handled courteously and sensitively a difficult mediation involving a claim by a former partner for provision under the 75 Act against an Estate of c £10m. Despite the parties’ opposing positions, and in the context of an emotionally charged encounter, Jonathan brought to bear his many years of experience as Chief Master and was able subtly to guide the parties to a compromise, saving them months of litigation and the uncertainty of a costly trial.”

“Jonathan Winegarten is one of the best mediators in the business.  He has a rare combination of intellectual brilliance and genuine empathy that allows him to both get to grips with complex and difficult matters and help parties find their way to a genuine resolution in an even handed and kind way.”
