‘Unstuffy, approachable and pragmatic advice with satisfactory outcomes.’

‘Mark Renouf is an exceptionally helpful advisor. Responsive, creative and reassuringly calm.’

‘Seymour Law LLP is a niche performer specialising in difficult trust litigation. The partners are both highly experienced in this area and most helpful.’

‘Both Mark Renouf and Jean-Marie Renouf can draw easily on their experience and have a good idea for much detailed work . They also are well versed in all up-to-date litigation procedures and directions, so can helpfully advise.’

‘Because the size of the firm is small I found them to be close to the case, hands on, and personally implicated at all stages. The communication is easy and efficient, the result of the case was therefore outstanding.’

‘Outstanding attention to detail and customer service. Very responsive and communicative. Creative, out-of-the-box thinking and solutions.’

‘I have worked with Jean-Marie Renouf. The qualities I value is that he is pragmatic and conscious of cost, particularly when dealing with individual clients. He offers sensible and workable solutions and suggestions, which are appreciated.’

‘Seymour is as yet a very small firm, which they have made into a strength rather than a weakness, in particular in their close collaboration between the partners and their hands-on approach to their work. They are adept at use of technology to move cases forward. Their approach is very team oriented. I have worked with them on cases where the clients are also professionals (trustees and similar), their strength is the ability to bring perspectives of all those involved – often geographically dispersed – to the problem and still move matters forward.’
