Thank you for choosing to instruct me in your case. I will need to collect and hold your personal information in order to represent you. I will take all possible steps to protect your personal information. I am determined to do nothing that would infringe your rights or undermine your trust. This Privacy Notice describes the information I collect about you, how it is used and shared, and your rights regarding it.


I am registered with the Information Commissioner’s Office (ICO) as a Data Controller for the personal data that I hold and process as a pupil. My registered address is Temple Garden Chambers London EC4Y 9DA and my registration number is ZB316253.


The vast majority of the information that I hold about you is provided to or gathered by me in the course of your case and/or proceedings. Your solicitor and/or I will tell you why we need the information and how we will use it.


The General Data Protection Regulation (GDPR) requires all organisations that process personal data to have a Lawful Basis for doing so. The Lawful Bases identified in the GDPR are:

  • Consent of the data subject;
  • Performance of a contract with the data subject or to take steps to enter into a contract;
  • Compliance with a legal obligation;
  • To protect the vital interests of a data subject or another person;
  • Performance of a task carried out in the public interest or in the exercise of official authority vested in the controller; and
  • The legitimate interests of ourselves, or a third party, except where such interests are overridden by the interests, rights or freedoms of the data subject.

Examples of legitimate interests include:

Where the data subject is a client or in the service of the controller;

Transmission within a group of undertakings for internal administrative purposes;

Processing necessary to ensure network and information security, including preventing unauthorised access;

Processing for direct marketing purposes, or to prevent fraud; and

Reporting possible criminal acts or threats to public security.

My Lawful Basis and Legitimate Interest can include all of the above as appropriate, but will generally be consent, performance or facilitation of contract, or legitimate interests.

  • Communicate with you about news, updates and events;
  • Investigate or address legal proceedings relating to your use of my services/products, or as otherwise allowed by applicable law; and

I do not transfer any personal data to third countries or international organisations.

I retain your personal data while you remain a client unless you ask me to delete it. My Retention and Disposal Policy (copy available on request) details how long I hold data for and how I dispose of it when it no longer needs to be held. I will delete or anonymise your information at your request unless:

  • There is an unresolved issue, such as claim or dispute;
  • I am legally required to; or
  • There are overriding legitimate business interests, including but not limited to fraud prevention and protecting customers’ safety and security.


The General Data Protection Regulation gives you specific rights around your personal data. For example, you have to be informed about the information I hold and what I use it for, you can ask for a copy of the personal information I hold about you, you can ask us to correct any inaccuracies with the personal data I hold, you can ask us to stop sending you direct mail, or emails, or in some circumstances ask us to stop processing your details. Finally, if I do something irregular or improper with your personal data you can seek compensation for any distress you are caused or loss you have incurred. You can find out more information from the ICO’s website http://ico.org.uk/for_the_public/personal_information and this is the organisation that you can complain to if you are unhappy with how I dealt with you.
