Claire O'Flinn

Spear's Review

‘I am almost the fourth emergency service,’ says Keystone Law family law specialist Claire O’Flinn. ‘Clients call me when they need urgent help. Sometimes this is because it is a legal emergency, and sometimes because it is an emotional one – and I treat them both with the same respect and importance.’

O’Flinn’s particular specialism is in UHNW financial settlements. Her career highlights include acting for an entrepreneurial wife who is the sole director of a company worth over £50 million, and acting for a wife in divorce with assets in excess of £20 million, including properties in London and four other European countries.

One recent case involved large holdings of cryptocurrency, the fluctuating value of which complicated the necessary estimation of the size of the marital assets. Her aim in such cases is to avoid costly court proceedings where possible.

She also specialises in matters concerning children and multiple jurisdictions and civil partnerships or unmarried couples. 

Adviser Profile

Family law specialist Claire O'Flinn, Partner, joined Keystone Law in 2013 and in the last eight years has grown her team to 7 members.

To her clients she simply is the fourth emergency service. Her clients call when they need urgent help. Whether it be a legal emergency or an emotional one, Claire is always ready to pull out all the stops, achieving outstanding results often in very difficult circumstances.

Claire’s client base is mostly made up from ultra-high-net-worth and high-net-worth individuals who often have very complex financial and family situations. Claire’s years of experience and technical know-how, compassion and determination to achieve the best outcome are of great comfort to her clients.

Claire has also been witnessing the continued effect of Brexit first-hand. She recently achieved a substantial settlement for a wife who jointly owned an agricultural company and properties with her husband. During the divorce he tried to claim she was a partner in name only in the business. This was something Claire disputed successfully and also managed to locate a pension that the husband had failed to disclose!

Known among her peers for her calm yet diligent approach, and for being hugely capable and really adding value to her cases, Claire is also highly appreciated by clients. ‘Words that come to mind are patient, persistent and generous with her time,’ enthuses one, while another praises her for ‘making a difficult process much more bearable’.

‘For me, realising that I'm a trusted advisor probably came years after I actually was one,’ admits O'Flinn. ‘When you realise that the great settlements are reached because of your skill, your knowledge and your capability, it begins to dawn on you that maybe you have the knack!’
