  • I'd like to thank you for all you have done for my sister and I. My previous experiences with solicitors have been consistently disappointing but you got everything right first time and achieved the result I sought in a reasonable amount of time.

  • The speed of response has been exceptional. Litigant correspondence is reviewed and provided to us along with draft responses in timescales that have consistently exceeded my expectations over a period of many months. There is a willingness to take feedback and make modifications which serves to create a strong sense of teamwork between client and advisor. David McGuire deserves specific note in this regard.

  • David was brilliant; always made sure that we understood the risks and implications of what action he took. He also reminded us of the consequences cost-wise, as in if an action that we take wanted to take and if the outcome would be worth the cost. There was fantastic communication that met our expectations. I asked for open communication when we first stared and he certainly delivered that. We had been wronged by our previous solicitor by not understanding where we were coming from of the point of the suit, as he thought it was a losing battle. David won he battle for us and we are absolutely pleased.

    Chambers and Partners 2025

  • David was our contact at Weightmans when we has a probate issue. We had contacted a number of legal firms before and after discussing our issue with David. David stood out as really listening and understanding our issue more than the other reputable firms we met in a very professional and personal manner. Subsequently we chose Weightmans and we were not disappointed. The issue was assessed, not in our favour unfortunately, in a very commercial, timely and professional way including pulling in additional resources where necessary to provide a clear outcome on our case.
