‘She is first class,’ says a source, adding: ‘From the outset I felt that I was in very good hands and I was absolutely delighted with her performance.’ She is a well-known mediator and negotiator but she has also taken cases before the Supreme Court and Court of Appeal. ‘If I had to choose one solicitor in the entire world that I admired the most it would be her. She is just astonishing – she identifies and resolves issues before you even realise there is one. She is just knockout, she really is,’ enthuses a peer.

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.

A mainstay of family law’s top tier for more than two decades, the former Withers chairman and Spear’s Family Lawyer of the Year Award winner is described by one pre-eminent peer as ‘three steps ahead of everyone else – counsel included’. Diana Parker enjoys one of the strongest reputations in the field for negotiating financial settlements for UHNWs out of court, and out of the press, typically at an early juncture.

Diana is a super star with vast experience, intelligence, judgement and style, She’s a very impressive and cool practitioner – she’s seen and done it all. Diana is very charming and deals with cases impeccably. Parker is also praised as extremely talented” and really pragmatic about her work.
She’s one of the best lawyers in this field, says a barrister.

One interviewee says Parker ‘has the best brain of any solicitor doing this work,’ explaining that ‘she is intellectually extraordinarily sharp and there is a clarity of thinking and analysis’ to her work, and that her ‘remarkable intellect also brings with it a very strong strategic awareness.’

Diana Parker is cool and considered. She is extremely intelligent with bags of experience. She is a top lawyer with a great intellect and strategic judgement.

She is intellectually streets ahead of everyone else. She has the most brilliant analytical brain, she is extremely smart in her strategy as well. She brings this razor-sharp intellect to bear on every case.
