Harriet Territt is a Partner at Jones Day. Her practice is centered on financial disputes and regulatory issues, with a focus on structured products such as CDOs, CLOs, derivatives, and repackaged debt. She also counsels and acts in disputes arising out of fund management disputes, syndicated facilities, asset-backed finance, and restructurings. Increasingly, she works with clients on issues arising out of innovative financial technology and alternative finance arrangements. Harriet has particular experience in multijurisdictional financial disputes, including securities fraud litigation, and she works closely with Jones Day's New York FILR team, including on Jones Day's representation of the various Lehman entities in bankruptcy. Harriet also represents clients in connection with investigations and proceedings brought by regulatory and enforcement agencies such as the Financial Conduct Authority and the Serious Fraud Office, with significant experience in the application of global financial sanctions. She deals with related regulation and law such as money laundering, bribery and corruption, has undertaken highly confidential internal investigations and compliance reviews for clients, and assists with crisis management. Harriet has extensive know-how in fraud-related litigation, including payment and tracing issues and trust litigation. As a result, she has substantial experience advising banks and trustees on the coordination of litigation in many other jurisdictions, including the United States, Italy, Brazil, and Russia, offshore jurisdictions such as the Cayman Islands, and the British Virgin Islands.




Solicitor of the Supreme Court of England and Wales. Harriet is also an external member of the Standards Committee of the SRA (Solicitors Regulation Authority) in the U.K. The SRA is the independent regulator of solicitors in the U.K.

  • US rules regarding offshore accounts

    The Hiring Incentives to Restore Employment Act 2010, enacted on 18 March 2010, imposes a new US withholding tax and reporting regime, known as the Foreign Account Tax Compliance Act (FATCA). The FATCA regime applies generally to payments made after 31 December 2012, except on obligations (to be defined in future guidance) outstanding on 18 March 2012. Substantial effort is required by foreign entities to bring their worldwide operations and policies into compliance with the FATCA rules as of the effective date.‚Ä©
