The team at Aaron & Partners have all been excellent, especially Simon Mawdsley. He has helped me get through this entire episode with professionalism, care, and in some circumstances, humour.
Client feedback via The Legal 500
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.
