On the Civil Fraud side, she acts for a variety of clients, both corporates and individuals, in complex and high value commercial disputes, involving Norwich Pharmacal Orders, freezing injunctions and other interim orders. Her cases are often of a cross-jurisdictional nature, involving allegations of breach of contract, misrepresentation, dishonest assistance, fraudulent trading, breach of trust and fiduciary duty, conspiracy and unjust enrichment.
On the Art Law side, she advises on a range of contentious art related matters, both high-profile disputes and smaller more discreet concerns, on issues including fraud, authenticity, provenance, conversion and ownership. She is experienced in advising on and assisting with the potentially significant reputational, commercial and personal considerations that can feature in such matters. She also regularly gives external training on fraud issues in the context of the art market, including on Christie's Education programme.
