A client is never just a client. Everyone you work with is an individual and the relationship you build with them is, in my view, as important as the advice you give them. You can have the best legal brain in the country but if you can’t relate to your client and explain your reasoning and thought process, it means very little, if anything at all. I always explain to clients why I am advising a course of action in clear, simple terms so we can reach an agreed view together. I always try and think how I would deal with the trials and heartache of litigation and put myself in the shoes of those who we represent.
Swimming made me. In my youth I was a competitive swimmer. I got up at 5.30am every morning and swam 3 miles. Your head is underwater, you can’t breathe, you can’t think straight because you are so tired and you have to work unbelievably hard. I still think that was pretty good training for life at the bar.
I did it the hard way. Achieving your goals is never easy. You always have to fight to reach the place you know you should be. I did a pupillage, a six-month extended pupillage and was a tenant at two sets of chambers before finally arriving at Serjeants Inn. When I first came to the bar I thought I would suit shipping law as it was an academic subject I particularly enjoyed at University. It quickly became apparent that this field of work gave me very little opportunity to meet individual clients and to help them solve their problems. I realised that while the legal aspects and arguments were both fascinating and intellectually challenging, the areas I now specialise in are far better suited to my strengths as an individual.
“A client is never just a client. The relationship you build with them is as important as the advice you give them.”
Emotional intelligence is typically overlooked. It is a given that when you instruct a barrister they will be confident, intelligent, and be able to grasp complex evidence and cross examine with vengeance. The ability to relate to clients and care about the difference you can make to their lives is often overlooked. If I were a client I would want to know that the person representing me really cared about my case. I strongly believe that having emotional intelligence and empathy can make you ‘stand out from the rest’.
People who are crazy enough to think they can change the world, are the ones that do (Steve Jobs). Many barristers start their working life thinking they will change the world. You realise very quickly that is unachievable but I continue to believe you can make a real difference.
Your family are the most important thing – for me and my clients. I couldn’t do what I do without them and my clients couldn’t either.
Let’s be modern. I have been fortunate to be involved in a number of very complex, significant group litigations. However these have their own complexities, particularly in terms of the management of a large number of claims and disclosure. This has taught me that managing documents and technology as whole is critical. I am a very modern barrister and will always strive to use technology where possible to manage the overall litigation process. I think the fact that my favourite mug says ‘I love spreadsheets’ says it all!
If at first you don’t succeed, try, try, try again. In every case there are setbacks. It’s about how you deal with them. Over my career I have had plenty (large and small) but they make you a better advocate. You may initially think a case is simple. It never is. Law evolves and changes almost every day. Barristers should always be aware of those changes and be conscious of how they affect every case you work on. You have to be prepared for anything and investigate every possibility. I endeavour to ensure that in every case I question every expert, look around every corner and leave no stone unturned.
