Aaron was called to the Bar in 2002 and joined Landmark Chambers in 2006. He has an established specialist practice in all forms of Property Law, along with matters suitable for the Chancery Division such as Company Law and Insolvency.
Aaron has been recommended in Chambers & Partners as a leading junior in Real Estate Litigation for some years now and is also consistently recommended by Legal 500 as a leading junior in Property Litigation.
His practice can be broken down into 5 key areas. Commercial Landlord & Tenant; Agricultural Land; Residential Landlord & Tenant; Real Property; and the interpretation of documents, and clauses within them, generally.
- In his commercial landlord and tenant practice, he deals with all issues of forfeiture and possession (including break options), 1954 Act renewal of tenancies, dilapidations and compensation for improvements, and rent reviews and service charge provisions, for both landlords and tenants. He represented the successful Respondents in the leading case on waiver of forfeiture and CRAR as it applies to commercial property.

As well as acting for a number of national developers in assisting in obtaining vacant possession of Agricultural Holdings, Aaron has advised farmers and land owners on a number of issues, and conducted hearings and arbitrations for those clients. He has also acted on negligence cases arising from advice given in relation to Agricultural Land.

- He advises and conducts litigation on numerous real property issues. His high profile and reported cases include High Court and Court of Appeal cases on the law of adverse possession and cases on proprietary estoppel and constructive trusts. His role as a FTT judge in the Land Registration division means his knowledge and experience of conveyancing issues, disputes regarding title and the registration of land, is significant. Further, he advises regularly on the interpretation of, and implementation of, easements and covenants; including representing clients in the Upper Tribunal seeking the modification or discharge of covenants binding their land. Aaron also acts and advises on cases involving Mortgages and Receivers, and Party Walls.
- Aaron has advised and appeared in, and has a special interest in, cases relating to the interpretation and enforceability of contracts generally, and especially those relating to sale and other transfers of interests in land, and the interpretation of clauses in leases. He advises regularly on option agreements, pre-emption agreements and joint venture agreements, as well as clauses within leases. Aaron is used to assimilating large amounts of historic documentation where necessary, and also forensically cross-examining witnesses to secure factual findings relevant to interpretation and intention.
Aaron has also appeared in a number of cases in both the FTT and Upper Tribunal in the specialist area of Mobile Home Act law, where he has represented a number of site owners around the country, as well as local authorities and residents’ groups, providing him with a good understanding of the issues that arise in many park home cases.
