Third edition of Leases: Covenants and Consents – out now
Jonathan Seitler KC
February 2023
Jonathan currently stands top of the pile in terms of KCs for heavy and important property litigation and property related professional negligence work. In a recent edition, Chambers & Partners says that “Jonathan is a god amongst counsel. A brilliant mind, fabulous with clients and a real pleasure to work with.” and “very user-friendly, a creative strategist and a superb advocate. Always impresses clients”. Another edition said that “his analysis is razor sharp” and “he is is very bright and highly commercial”.
In 2022, Jonathan was awarded Chambers & Partners’ Real Estate Silk of the Year, which he has won on three separate occasions in the past, along with The Legal 500’s Award for Real Estate, Environment and Planning Silk of the Year. Jonathan has accomplished these plaudits with a simple approach: his enormous success and enduring popularity has been achieved by immensely hard work, deep attention to detail, speed and decisiveness.
Jonathan is presently involved in many of the leading cases in property litigation and property related professional negligence and is widely respected and admired for bringing to every matter, irrespective of how complex, clarity, commitment and care. Jonathan is strongly of the view that technical excellence in legal matters can be found quite easily: what makes the difference in terms of a successful lawyer are abilities on top of those – the ability to communicate clearly and effectively with clients and in particular to reflect their commercial objectives; the ability to think strategically about how to counter the move that the enemy is going to make next (even if it hasn’t yet thought of it itself); and ultimately, the ability to persuade the court to do something that it wouldn’t otherwise do.
Jonathan has been Deputy Head of Chambers at Wilberforce since 2016.

Property
Jonathan was named Chambers & Partners’ Real Estate Silk of the Year in 2022, 2015, 2010 and 2007.
Jonathan is also the author of several books: ‘Claims against solicitors and valuers’, ‘Commercial Dispute Resolution’ and the bestselling ‘Leases: Covenants and consents’.
Jonathan has been involved in over 100 reported cases and many hundreds more either unreported or confidential. In essence, anything with even a tangential property angle, is ‘meat and drink’ for Jonathan.
Here’s a sample of Jonathan’s reported cases in the High Court, Court of Appeal and above over the past few years:
A legend in the area of property disputes, the way Jonathan’s mind works in order to find angles supporting a legal argument is truly fantastic.
His advocacy skills and powers of persuasion are second to none, controlling the courtroom with his smart wit and at times humour. He is fantastic with clients and great fun to work with on a case.
Jonathan’s ability to think outside of the box is remarkable. The way his mind works to find angles is fantastic. His advocacy skills are second to none, fantastically persuasive on his feet.
Jonathan is a god amongst counsel. A brilliant mind, fabulous with clients and a real pleasure to work with.
Very user-friendly, a creative strategist and a superb advocate. Always impresses clients.

Jonathan has over 20 years experience in acting as an arbitrator or as expert in an expert determination, having started this aspect of his practice in the mid-1990’s. His Awards and Determinations have covered all areas connected with property litigation and related professional negligence, including:
Jonathan’s manner is perfectly suited to winning the confidence of clients on both sides of a dispute and then resolving it in a way which is not just in accordance with the law and procedure and not just swift and economical, but is also in a manner which allows even the unsuccessful party to be assured that it has had a fair hearing and a proper disposal of its argument. This ensures that whilst the party in the right prevails, commercial relationships and not ruined going forward.
Jonathan’s track record as an arbitrator and Expert is such that the market continues to provide a him with a steady flow of this type of work. This is the strongest testament to his success in the field.
Jonathan is very calm and intelligent. He makes sure clients are happy and is quick to clarify why there is a strategy; he doesn't leave them in the dark.
Mediation
Jonathan has been a qualified mediator for 15 years over which time he has carried out hundreds of mediations. His style is firm but friendly and his skill is in not having the wool pulled over his eyes yet using the clear vision this provides to maximum effect (which usually means not making a big deal about it). His success rate in mediations is very high and he is particularly chuffed that such success is often achieved without having to continue the mediation beyond normal office hours. Jonathan also appeared for the successful party in the Court of Appeal in PGF v OMFS [2013] EWCA Civ 1288, the case which laid down the principles for the punishment of parties who ignore invitations to mediate.
Jonathan carries out mediations across all aspects of civil litigation and particularly enjoys cases with a property or related professional negligence angle.
Jonathan is also available to offer early neutral evaluations.
Jonathan is able to look at matters from a new perspective and different angles.
