Profile

Sebastian’s practice covers a variety of business, property and common law work.

His business and property work principally relates to insurance (including indemnity/policy avoidance), contract, company/partnership and real property issues but also includes probate, trust and inheritance/1975 Act claims. His company and partnership cases include dissolution and insolvency matters as well as fraud (diversion of profits, breach of covenants and fiduciary duties), minority shareholder’s rights, complex scenarios involving partnership shares and assets, trademarks and copyright. His real property work covers TOLATA, commercial landlord and tenant, mortgages, conveyancing, registration, restrictive covenants and management charges as well as boundaries and easements.

Much of Sebastian’s case load falls under the umbrella of common law and regulatory work. He is familiar with all aspects of local authority work. He has a particular speciality in nuisance claims/claims involving water (flooding, environmental pollution, culverts, drainage etc). His regulatory work covers financial services (FSMA), waste management, Building Act enforcement and regulatory compliance both corporate and professional (including professional discipline).

Sebastian has over 25 years call. Whilst the mainstay of his practice is commercial, chancery and other common law work, his pupillage and early practice focussed on personal injury and related professional negligence. As a result, his professional negligence work is able to cover the full spectrum. His insurance indemnity work specifically includes motor insurance indemnity cases.

Sebastian has advocated in a wide variety of forums including the Court of Appeal, High Court (Chancery, Queen’s Bench, Commercial, Companies and TCC), County Court, Arbitration, Mediation, Upper Tribunal (Lands Chamber), and First-tier and Adjudicator to HM Land Registry. His work includes emergency applications for freezing orders and injunctions.
