Joanna Grandfield

Spear’s Review

Financial and children law specialist Joanna Grandfield leads Mills & Reevefamily team in London. She prides herself on taking the time to get to grips with a case’s legal complexities alongside the client’s intentions and ‘working together to formulate a strategy and create a team to achieve it’.

A trained barrister and mediator, Grandfield practices collaborative law, drafts pre- and postnuptial agreements and advises on wealth protection issues for her clients, who include individuals, trustees and family offices. One client describes her as a ‘tremendous asset’, adding that she is ‘calm, assured, diligent and clearly very knowledgeable’.

Grandfield also has served as a trustee for a charity providing mental health services to children and young people.

Adviser Profile

Head of the children and family team and former board member at Mills & Reeve. A barrister, mediator and collaborative family lawyer, Joanna advises high- and ultra-high-net-worth individuals, trustees and family offices nationally and internationally on issues arising at the start and end of a relationship.

One client describes her as ‘fantastic throughout – efficient, pragmatic and clever’, a ‘tremendous asset’, while counsel says ‘Joanna is really first rate – bright, engaging, always really constructive but doesn’t take any prisoners.’

Another area of interest for Grandfield is mental health – she has acted as a trustee on a start-up charity that provides mental health services to children and young people.
