This Practice Note provides a summary of the steps taken by the UK, the EU and the G20 towards transparency and highlights issues that may be of particular interest to Private Client practitioners and trustees. For guidance on the due diligence requirements imposed on Private Client practitioners or their law firms, see Practice Compliance content, including: Client due diligence—law firms—overview. Global developments towards beneficial ownership transparency In 2014, the G20 agreed high-level principles on beneficial ownership transparency. In March 2015, the UK government introduced legislation which requires a UK entity to keep a register of people who have significant control (PSC) over the entity from April 2016. A public register of PSCs (the PSC Register) became operational on 30 June 2016.
