Practice head(s):

Jean-Marie Renouf


‘Personal service and expertise from well established partners who are highly thought of in their chosen areas. This means the legal advice is of high quality and to the point and the process of obtaining it efficient and cost effective.’

‘Advocate Jean-Marie Renouf was attentive and responsive and ready with a summary of the key practical issues and focussed pre-emptive words of advice to manage expectations regarding the negotiations to be undertaken. He has an excellent grasp of employment law and whilst he will present the position at each end of the spectrum, is ready with pragmatic realistic advice. He also showed great client care and was a reassuring point of reference checking in and following up from time to time.’

‘I recently engaged Jean-Marie Renouf in relation to a recent employment dispute with my former employer. It required a very swift turnaround of less than a week. Jean-Marie made himself available to assist me in an urgent matter at very short notice, which was appreciated. In all of my dealings with him, I have found him to be highly effective, knowledgeable, responsive, and empathetic. When handling a personal matter rather than a corporate matter, this is all the more important. This is in comparison with other lawyers with whom I have dealt who do not communicate and leave clients waiting for days with little consideration. Jean-Marie’s advice is robust, thorough, and pragmatic.’
