Dainyah has a broad commercial practice with particular experience in contractual disputes, insolvency, company law, and banking litigation, frequently involving cross-border and multi-jurisdictional elements.

Dainyah has been involved in matters before the Eastern Caribbean Supreme Court and has assisted in proceedings before the Privy Council and the English Commercial Court. Her work combines technical legal analysis with a practical understanding of complex financial and corporate structures, making her well-suited to cases involving offshore entities and international disputes.

She is able to work across Chambers’ broader practice areas and can provide assistance in general civil and commercial hearings, including winding-up petitions, county court matters, and related civil or commercial proceedings.

Dainyah has worked on a number of high-profile, complex, and high-value cases, including:

A high-value conspiracy claim brought by a former Russian businessman alleging state and corporate collusion to seize assets worth $14 billion; successfully challenged the English court’s jurisdiction.
A Privy Council appeal that clarified BVI law and influenced legal principles in England and Wales.
A LCIA arbitration exceeding £1.6 billion, involving allegations of breach of contract and fraud.

Her experience includes drafting pleadings, skeleton arguments, and written advices across a range of commercial issues, including unjust enrichment, cross-border insolvency, sanctions compliance, and foreign judgment enforcement. Dainyah has appeared before the Eastern Caribbean Supreme Court in procedural hearings and is committed to access to justice through her participation in pro bono schemes, including the Company Insolvency Scheme, Advocate, and the Free Representation Unit.

Dainyah worked in the Supervision, Policy and Competition Division of the Financial Conduct Authority, where she managed implementation projects and completed a secondment to the Financial Crime Specialist Directorate. There, she reviewed sanctions systems and controls at major international banks and handled cases involving suspected sanctions breaches.

Before that, she was an Intelligence Analyst, investigating complex civil fraud, white-collar crime, and high-value trust disputes.

Earlier in her career, Dainyah spent time as a Legal Intern in the Judges’ Chambers of the International Criminal Court, where she contributed to the conviction and sentencing judgments in the Ntaganda case.
