Iain Mackie Partner

Iain specialises in large-scale corporate and financial services litigation and arbitration for a mix of UK and international corporate clients, private equity houses, family offices and financial institutions.

He became head of litigation and dispute resolution in 2008.

Iain advises on a wide range of corporate disputes including: shareholder disputes; claims for breach of fiduciary duty against directors and senior employees; fraud issues; the rights and obligations of directors; derivative actions and unfair prejudice petitions; insolvency issues and restructuring. He also handles disputes arising out of mergers and acquisitions, joint ventures and warranty claims, often of a multi-jurisdictional nature and has particular expertise in matters involving private equity investments.

He acts for banks, financial institutions and fund managers in relation to disputes concerning fund and asset management, lending/security, complex financial instruments (particularly derivatives), trade finance and internal investigations. He has extensive experience of regulatory investigations by the FCA and other regulators, both in the UK and elsewhere, and advises on market abuse and compliance issues.

He is regularly involved in advising non-UK clients involved in English law disputes, particularly in relation to international arbitrations concerning commercial and corporate matters, and in dealing with complex cross-border litigation.


What people are saying


"He is a skilful advocate with expertise in handling corporate cases relating to directors' duties, post-M&A disputes and unfair prejudice petitions, among other matters. Sources say: 'He is superb - deceptively softly spoken and incredibly calm and pleasant in his demeanour, which hides a really steely intellect and tactical nous.'"
