Hannah is a formidable silk renowned for her role in leading and appellate cases, often those which tackle ground breaking areas of law.
Since taking silk Hannah has balanced complex private law cases, international children law cases and appellate work with the most serious of public law (care) cases.
Private law cases involve those with the most serious of issues, domestic abuse, alienation and emotional abuse; physical abuse including sexual and those with international and complicated relocation (both internal and external) arguments.
Known for her work in cases involving serious allegations of sexual abuse, physical abuse and emotional harm, she is also highly regarded in her work in medical cases: non accidental injury, shaken baby syndrome and cases involving mental health issues. Hannah’s work also focuses on judicial review issues both within family law cases and as free-standing issues.

L v (1) L (2) N (BY HER CHILDREN’S GUARDIAN) (2017)
A child arrangements order was made specifying with which parent a child should live when she was in the future discharged from hospital where she was being treated for an eating disorder. Although it was unusual to make an anticipatory child arrangements order, the child had an urgent need for certainty in her living arrangements once discharged, and continued uncertainty would detract from the possibility of her recovery.
BARNET LONDON BOROUGH COUNCIL v AL & 9 ORS (2017)
Where the local authority and the mother disagreed as to whether a baby who was subject to an interim care order should have vaccinations, the court made a declaration under its inherent jurisdiction that it was in the child’s best interests for the local authority to arrange for him to receive them.
RE H (DOMESTIC SURROGACY ARRANGEMENT) sub nom (1) B (2) A v (1) C (2) D (3) (BY HER CHILDRENS GUARDIAN ANGELA ADAMS) (2016)
Where a surrogacy agreement between male same-sex partners and the surrogate and her husband had broken down, with the latter unwilling to give up the child, it was in the child’s best interests to place her with the same-sex partners. The placement would best meet her identity needs in the wider sense of her being a child of intended gay parents, whereas the surrogate and her husband had formed entrenched negative views of the partners and were unlikely to be able to give an accurate and balanced view to the child about her circumstances and background.
