Diana and Adele delivered a quick and efficient solution in my divorce negotiations. Adele comprehensively and promptly put together my complex financial disclosure, and within a matter of weeks I was able to reach an overall agreement with my wife during an all-day lawyer led mediation, with the help of their strategic advice and eye for detail. The swift and amicable approach they facilitated enabled my wife and I to move on without bitterness. I can highly recommend them for providing creative ideas, achieving results, and also being pleasant people to work with.

Diana has been right at the top of the industry for a very long time. Both Diana Parker and Laura Winterbottom were an unbeatable team for me that it was a joy to work with. They are not only extremely effective but also lovely people.

My experience of Diana Parker and Laura Winterbottom of Withers is that they are totally professional, with unrelenting energy and enthusiasm. They left no stone unturned. My case was also dealt with in a strategic manner where I was introduced to the most appropriate external additional resources that could be found. The style was at all times polite and correct towards the opposition. They showed superior attention to detail and are very organised. I felt I obtained a great service and superior advice throughout.


I was lucky enough to find Withers at a very difficult time in my life. Diana’s calm and assured understanding of my situation helped me to focus on what I needed to do and Adele helped me work step by step through this difficult process in a sympathetic, structured way. Nothing can make these things easy, but without Withers and Diana’s and Adele’s expertise in calmly negotiating each obstacle and complication as it came up, my emotional state at the time and my situation now would certainly have been much worse.

Il mio profilo in un minuto

Seeing my clients looking forward with confidence is very motivational

What I enjoy is the fulfilment of helping someone move out of the chaos and recriminations of relationship breakdown and doing that as swiftly and with as sure a touch as possible. Seeing my clients looking forward with confidence rather than looking back in anger is very motivational.
