Adam is a specialist in proprietary estoppel with additional expertise in probate and will cases. He attracts praise for his down-to-earth approach. ‘He is a delight to work alongside and is hugely impressive to clients. He takes a realistic approach not just on the legal issues, but on pragmatic and strategic decisions through the life of a case, too.’

Proprietary estoppel is one of Adam’s main specialisms. As a pupil he attended the Court of Appeal with Leslie Blohm KC (now HHJ Blohm) in the now famous case of Davies v Davies [2014] EWCA Civ 568. Adam then wrote the article ‘The Promised Land’ which analysed the main issues in the case and was published in the Law Society’s Private Client magazine. He was later instructed to act for Eirian Davies and appeared alongside the silk in the matter’s second trip to the Court of Appeal on the topic of quantum (Davies and Another v Davies [2016] EWCA Civ 463). He has since been involved in another reported proprietary estoppel / common intention constructive trust case – Culliford v Thorpe [2018] EWHC 426 (Ch).

Adam is now a “go to” barrister in this area. He is frequently instructed in high value, complicated, estoppel cases, including trials in the High Court heard over numerous days.

In addition, Adam has given a variety of talks and seminars on the topic of proprietary estoppel, and maintains an ongoing academic interest in the evolution of the doctrine.

Most recently, he wrote an article for Lexis Nexis on the leading case of Guest v Guest [2022] UKSC 27. Read here.
