Dispute Resolution

A kind, empathetic and on-the-ball solicitor.

I was lucky enough to have William Cook as my solicitor on a really traumatic and tough case. William has been absolutely amazing throughout this whole process. He has been kind, empathetic and understanding. I've had various experiences with solicitors over the years and I've never dealt with anyone as lovely and professional as William. He would reply to every email within hours, always answered his phone or called me back and I always felt like he really cared about me and my situation. He made me feel like I was very important and I also know how much he wanted to get this resolved for me. I can't thank him enough for how he handled this case. I've been going through a lot of mental and physical health struggles throughout this time, which I shared very openly, and I can't imagine that was very easy to deal with. But William never spoke out of turn and was always very empathetic. A big thank you.

I want to sincerely thank William for the outstanding service and support he has provided throughout my case. From the very beginning, he has been professional, approachable, and incredibly thorough. His attention to detail, clear communication, and genuine care made a stressful situation much easier to navigate. He always kept me informed and made sure I understood every step of the process. I truly felt like I was in safe hands, and his dedication to achieving the best possible outcome did not go unnoticed. I couldn’t have asked for better support. Thank you again, William, for everything you’ve done for me—I genuinely appreciate your hard work and commitment.

William Cook was a constant professional throughout the process. He reassured me with his concrete knowledge of the process and the area of the law required in regards resolving the dispute. He responded promptly to my questions and listened to what information I had regarding the dispute and wrote eloquently put together responses to the other party. Thoroughly happy with the service. Thank you William.

We received nothing short of an exceptional service and given to the logistical problem of being in another country, dealing with a tenant who refused to move out made the problem even more difficult. Thanks to Mullins & Peake and their staff we were able to remove the tenant within 3 months of them coming on board. Previously we had spent 7 months trying to remove the tenants and got nowhere. I thoroughly recommend their services and would have no hesitation in recommending them.

I dealt with William for the caveat and will of my mother. He was absolutely excellent and extremely efficient. I also dealt with Emma boys-smith for my mothers probate and she too was marvellous, totally impressed with both individuals
