Chambers UK 2020

Oliver is an experienced barrister with a busy practice in family and civil law.

The focus of Oliver’s family practice is on the law relating to children, in particular care proceedings. The focus of his civil work is on personal injury, clinical negligence and CICA claims.

Oliver’s practice in personal injury and clinical negligence law has provided him with a distinct advantage in the many family cases that concern complex medical issues. Similarly his experience in public law children’s cases gives him an invaluable insight into civil claims that involve the abuse of children and the involvement of Social Services.

He has a burgeoning practice in Court of Protection work in matters relating to both welfare and financial affairs.

As an advocate, Oliver has the benefit of drawing on a common law background, which has given him exposure to a wide variety of tribunals, including jury trials. Oliver is qualified to accept Direct Access instructions.


The focus of Oliver’s family practice is on public law proceedings in which he represents local authorities, parents, extended family members, prospective adopters and children via their guardians. He is regularly instructed in complex cases concerning serious non-accidental injury, sexual abuse and complex mental health issues. Oliver is used to dealing with international issues concerning jurisdiction and placements abroad.

Oliver is also regularly instructed in private law disputes, in particular where there are allegations of serious physical or sexual abuse, cases involving intractable hostility and where the children are separately represented.
