de Waal QC

"QC clout without the QC attitude​" - Legal 500

Year of call: 1992


John de Waal QC specialises in chancery and commercial work with a particular focus on property law and property-related professional negligence.

He is regularly instructed in complex property-related litigation in the Chancery Division and Court of Appeal. In the last few years he has appeared in the House of Lords in the leading case on economic torts, OBG Ltd v Allan [2008] 1 AC 1 and in the Supreme Court in the leading case on the law of penalties ParkingEye Ltd v Beavis [2015] 3 WLR 1373.

John’s professional negligence practice is national in scope. He acts largely, but not exclusively, for defendants. He is instructed by most solicitors' professional indemnity insurers and their panel firms and is recommended in this area as someone who is “very commercially minded and understands both the law and the marketplace in which we work." 

John won Real Estate, Environment and Planning Silk of the Year in the Legal 500 2017 Awards.


John particularly enjoys working as a mediator and has acted as lead mediator in over 100 cases. For more information about John's mediation experience, please view his Mediation profile.
