Garry Manley is a partner in our Isle of Man office who advises on a broad range of Isle of Man and BVI corporate transactions. He has extensive experience of advising on domestic and cross-border mergers & acquisitions and venture capital/private equity investments, with a particular focus on regulated financial services and insurance businesses.

In addition to his M&A practice, Garry is one of the Isle of Man’s leading regulatory lawyers, with a particular focus on insurance companies, banks and corporate service providers. Garry’s insurance work sees him advising many of the Isle of Man’s leading insurance groups and insurance managers on the full spectrum of matters including M&A transactions, portfolio transfers, new authorisations, change of control applications and ongoing business regulation, including solvency issues. In addition to the regulation of traditional sectors, Garry advises on a range of novel and developing regulated industries, including payment services and cryptoassets. He is a pre-eminent thought-leader in respect of the regulated cannabis sector on the Isle of Man and is also distinguished in the area of economic substance, having been the only lawyer on the Isle of Man government’s public-private working group since 2019. He also supports clients in contentious regulatory matters, including regulatory investigations and enforcement proceedings, alongside colleagues in Appleby’s market-leading disputes team.

Garry has a first- class law degree from Oxford University, and before joining Appleby he practised for almost a decade as a mergers & acquisitions and transactional private equity specialist in the London, Hong Kong and New York offices of Cleary Gottlieb Steen & Hamilton LLP.

In addition to his advisory work, Garry frequently provides input into legislative developments across a broad range of topics. He was closely involved in the development of the Isle of Man’s first merger control regime, and he has also been consulted about legislative developments in the areas of company law, cannabis regulation, economic substance and beneficial ownership.
