We are thrilled to have strengthened our real estate disputes team with the appointment of Jonathan Warren as a partner in London.

Jonathan joins the firm from Teacher Stern, where he was joint head of the real estate disputes department. He brings more than 17 years’ experience in property litigation, having previously worked at Finers Stephens Innocent (now Howard Kennedy), Mishcon de Reya, and as in-house counsel at one of the UK’s largest residential property management companies.

A highly regarded specialist in property litigation, Jonathan advises on all aspects of real estate disputes. His practice encompasses the full spectrum of property litigation, landlord and tenant litigation, risk analysis, and alternative dispute resolution. In the past two years, he has also led high-profile cases arising out of the Building Safety Act, including some of the first remediation contribution order and building liability order claims.

In his new role, Jonathan will focus on strengthening our London real estate disputes offering, supporting complex litigation matters, and helping drive the team’s continued growth.

Jonathan said: “I’m thrilled to be joining Shakespeare Martineau and contributing to the growth of the London office. The opportunity to help develop our real estate disputes offering and work with a talented, forward-looking team is incredibly exciting. I look forward to helping clients achieve creative, effective solutions to complex problems while supporting the next generation of lawyers in the team.”

Jonathan’s recent work highlights include defending clients in Building Safety Act claims, securing specific performance and vacant possession in high-value residential property transactions, recovering unpaid agent commissions, and forfeiting commercial leases subject to closure orders.

Victoria Tester, managing director, said: “Jonathan is a highly skilled and trusted litigator with deep experience in complex property disputes. His commercial insight, technical expertise and track record of delivering results for clients make him a fantastic addition to the team. His appointment strengthens our London real estate disputes capability and aligns with our strategy to provide innovative, client-focused solutions in this area of law.”
