Claire van Overdijk is a specialist private client and public law barrister. She is described as a “very versatile, experienced and persuasive advocate” and was shortlisted as “Advocate of the Year” at the 2019/2020 STEP Private Client Awards.

Owing to her expertise in private international law, Claire is also recognised as an expert in jurisdictional issues both in the public law and private client fields, and is described as “exceptional in cases involving complex overlapping issues of jurisdiction, finance, or particularly difficult family dynamics.

Expertise

Claire has extensive experience in mental capacity law and is the first and currently the only practitioner at the Bar to date to be recognised as a leader in both areas of the COP’s jurisdiction (Chambers & Partners Band 2 for both Health & Welfare and Property & Affairs). Claire has published widely in the mental capacity field and her expertise in private international law has also led to her being known as “go-to counsel for international mental capacity matters”.

Her COP practice is equally split between health/welfare and property and affairs. She is particularly adept in complex hybrid cases where a mix of issues arise. She receives instructions from a range of clients such as the Office of the Public Guardian, the Official Solicitor, public bodies (local authorities, NHS Trusts/ CCGs, central government), deputies and private individuals.

Claire’s mental capacity practice is complemented by her public law and private client practice, which enable her to provide tailored advice to clients as appropriate.
