I am recently divorced, and Simon has been my solicitor. Without his calm and considered advice and support, I would have found an already stressful situation even more difficult. Even when I asked him the most ludicrous questions, at no point did he make me feel foolish, and he remained professional but very approachable throughout. I feel fortunate to have been represented by him.

The Team at Aaron & Partners have all been excellent, especially Simon Magner Mawdsley, He has helped me get through the whole episode and has done so in a professional, caring and in some cases funny manner [...] I cannot say How highly I regard him. If anyone needs a great divorce solicitor, then this is the man to contact. Yes he was my solicitor, but honestly in the process he also felt like a friend.
