Jonathan’s cases invariably involve land and property but span commercial, company, fraud, trust and insolvency law disputes and related professional negligence.
He is equally happy acting in large, complex litigation as a part of a team as he is representing an individual landowner, developer or leaseholder. He has appeared in courts and tribunals at all levels from the First-tier Tribunal to the Supreme Court. He also acts in mediations and arbitrations. A significant part of his practice is appellate work, including cases in which he did not appear below. Jonathan is frequently against silks as sole counsel.
Jonathan is frequently instructed in relation to development agreements and joint ventures, contracts for sale, overage, options, injunctions, specific performance and orders for sale.
Jonathan has particular experience of cases involving fraudulent dispositions, sham transactions and allegations of dishonesty. He is a seasoned trial advocate and has been involved in a number of cases involving the bona fides of a declaration of trust including Tigris Industries Inc v Ghassemian [2016] EWCA Civ 269; Saranovic v Saranovic The Times, March 21, 2017; and Premium Jet AG v Sutton [2017] EWHC 186 (QB).
His trusts work encompasses co-ownership disputes and applications for orders for sale/TOLATA claims. He successfully argued for a resulting trust analysis in Chaudhary v Chaudhary [2013] EWCA Civ 758; [2013] 2 F.L.R. 1526; [2013] Fam. Law 1257, cited in all the leading texts. He successfully appeared in the Upper Tribunal (Fancourt J) concerning the First-tier Tribunal’s jurisdiction to determine an application by joint trustees in bankruptcy to register a restriction against a property held in joint names (Wolloff and Dante (as Joint Trustees in Bankruptcy of Alexander James Dhillon) v Patel [2019] UKUT 333 (LC)).
Jonathan has been ranked in Chambers & Partners and the Legal 500 for many years. He has very recently been described as “A silk in waiting. He has an unwavering ability to get to the commercial crux of a matter extremely quickly” and “the perfect package for complex and hard-fought property litigation, Jonathan is both technically brilliant and a creative advocate.” He “combines a sharp mind, deep knowledge, experience and seasoned advocacy with consummate client-handling skills”; he is “very cerebral, persuasive towards judges, prompt and easy to deal with”; and “a good all-round property barrister with both residential and commercial expertise”.
Jonathan’s practice includes the full spectrum of real property and commercial and residential landlord and tenant disputes.
He has significant experience in rights of light disputes and disturbances of other easements, acting for both developers and land owners, involving claims for injunctive relief and damages in lieu. His cases frequently involve expert evidence on negotiating damages based on a share of development profit. His recent work includes a claim for £1.9m arising out of the redevelopment of a prominent site in Shoreditch.
Jonathan advises and litigates on joint venture disputes and other matters relating to land including contracts for sale, overage, options, injunctions, specific performance, possession and orders for sale.
He is acknowledged as a leading practitioner in the field of restrictive covenants. Recent cases include:
Jonathan’s extensive knowledge of the statutory protections in the residential landlord and tenant context make him the first choice counsel on matters affecting mixed-use developments. He advises and litigates on lease interpretation, tenants’ rights of first refusal, leasehold enfranchisement, right to manage, variation of leases and service charges. His cases frequently involve large group litigation. Notable cases include:
The majority of Jonathan’s cases include issues relating to contractual interpretation, very often in the context of development disputes. His practice includes business disputes between commercial parties and involves commercial fraud, enforcement of judgments and asset tracing.
He has significant experience of applying for urgent injunctive relief, including proprietary injunctions and freezing orders.
Jonathan particularly enjoys working as part of a team in large, complex litigation where he leads on property-related issues.
He accepts instructions in disputes (litigation and arbitration) in the Cayman Islands, British Virgin Islands, Jersey, Guernsey, the Dubai International Financial Centre and Bermuda.
Jonathan has extensive experience of cases involving fraudulent dispositions, sham transactions and allegations of dishonesty. He is a seasoned trial advocate and has been involved in a number of cases involving the bona fides of a declaration of trust including Tigris Industries Inc v Ghassemian [2016] EWCA Civ 269; Saranovic v Saranovic The Times, March 21, 2017; and Premium Jet AG v Sutton [2017] EWHC 186 (QB).
He is highly sought after in such cases for his forensic eye for detail and his prowess in cross-examination at trial.
Jonathan has acted as sole counsel on company matters including applications for restoration to the register, petitions under s.994 of the Companies Act 2006 and cases concerning directors’ duties. He is particularly experienced on matters relating to the management and administration of companies owned and controlled by leaseholders.
Jonathan’s trusts work encompasses co-ownership disputes and applications for orders for sale/TOLATA claims in both the domestic and commercial context. He successfully argued for a resulting trust analysis in Chaudhary v Chaudhary [2013] EWCA Civ 758; [2013] 2 F.L.R. 1526; [2013] Fam. Law 1257, cited in all the leading texts.

Jonathan acts in a range of professional negligence disputes, invariably involving solicitors, valuers, surveyors and other property professionals. His extensive knowledge of the underpinning substantive property law and/or valuation principles makes him a natural choice.
Recent work includes a claim against solicitors for failing to register a transaction in circumstances where the vendor subsequently re-sold the property to an innocent third party.
Jonathan has significant experience in banking and financial services disputes. He has acted in many high value cases about the enforcement of securities in regulated and unregulated lending. He is often instructed to advise and act in securities and receivership cases where enforcement is challenging.
Recent works include Uthyavel v Raviraj [2021] EWHC 501 (Ch), a 5-day trial regarding a complex partnership dispute about a business and properties in East London.
