Experience and Expertise

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.

At the Bar he was known for his clear-thinking, good knowledge of law and procedure, excellent advocacy skills, courtesy and good humour. These attributes he brought with him to the Bench where in addition he displayed fair-mindedness, a pleasant manner and an ability to put parties at their ease. He was noted for his ability to see to the heart of a problem and help litigants resolve matters at an early stage.

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 action, 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 comment received from mediation clients:

“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.”
