Position

Aaron has significant experience in appellate jurisdictions including appearing un-led in several groundbreaking and high profile cases in the Court of Appeal.

Aaron is acknowledged and recommended in Chambers and Partners as a leading junior in Real Estate Litigation and is also consistently recommended by Legal 500 as a leading junior in Property Litigation, where he has been described as “a fantastic advocate”, “clearly highly intelligent and has a thoughtful approach to work”, and “very bright and knowledgeable and doesn’t go down without a fight”.

His practice can be broken down into five key areas. Commercial Landlord and Tenant; Agricultural Land; Residential Landlord & Tenant; Real Property; and the interpretation of documents, and clauses within them, generally. He regularly gives talks and presentations on new and interesting developments within those fields. His specialist knowledge is recognised by his current appointment as the consultant editor of all volumes of Halsbury’s Laws: Landlord and Tenant.

He has been involved in a number of high profile matters including acting for many well known developers and house builders, local authorities, and large infrastructure providers including HS2, Transport for London, Network Rail, the Highways Authority, the Environment Agency, as well as various departments of His Majesty’s Government. In many of his recent cases he has been instructed as sole counsel with silks appearing against him.

Outside of the law, Aaron is a keen sportsman. He is a member of the MCC, Middlesex CCC, and a season ticket holder at Harlequins RFU. He also retains a season pass at the French ski resort of Les Deux Alpes, and tries to get there for as many weekends as work will allow during the winter.
