Instructing us

We have a skilled and experienced team of clerks. They are:

Justin Brown
Steve Anten
Frank Lee

We believe that our clerks provide a service which is second to none. They pride themselves on their ability to recommend the right barrister (or team of barristers) for a particular case. They have formed a strong working relationship with all the listing departments of the High Court and are happy to offer advice on listing matters.

A member of our clerking team is always available outside office hours if assistance is required urgently.

We welcome instructions from solicitors (whether in private practice or in-house), qualified foreign lawyers, and clients licensed by the Bar Council to give instructions directly to barristers under the Licensed Access Scheme.

Barristers may also accept instructions directly from clients in foreign jurisdictions, except if the work relates to proceedings in a UK court or tribunal.

Some members of Thirteen Old Square are also qualified to accept instructions directly from companies and individuals in the UK under the direct access rules. For details, please contact the clerks.

Terms of Business

Unless otherwise agreed the Standard Conditions for the Supply of Legal Services by Barristers to Authorised Persons 2012 ("the Standard Conditions") apply to all work undertaken by barristers at Thirteen Old Square on the instructions of solicitors or other Authorised Persons (as defined in the Standard Conditions). A copy of the Standard Conditions may be found here.

Upon accepting instructions our clerks will agree the basis upon which the client is to be charged for the work to be done. In some cases we will charge on the basis of an agreed hourly rate, which will be set by reference to the nature of the case and the experience of the barrister instructed.

For advocacy services a brief fee (plus refreshers, where appropriate) will generally be agreed. This will be based on the nature of the case, the likely length of the hearing and the experience of the barrister instructed.

Our clerks appreciate the need to be flexible in their approach to fees and are happy to discuss a wide variety of fee arrangements.


We always aim to provide our clients with an excellent service. However, if you have a complaint you are invited to let us know as soon as possible. It is not necessary to involve your solicitors in order to make your complaint but you are free to do so should you wish.

Please note that Chambers will only consider complaints that are raised within six months of the act or omission complained of.
