Joint Head of Chambers
Sarah has developed her practice in children cases over the last 18 years, initially at a specialist family law set in London and since 2008 on the North Eastern Circuit at what is now Spire Barristers. She appears on behalf of local authorities, parents, extended family members and Children’s Guardians and often represents parents suffering from mental illness, those with severe learning difficulties as well as ‘child parents’ in serious, complex cases (both public and private law), involving serious non-accidental injury and sexual abuse, often including both issues in the same case, as well as cases involving neglect, mental health issues, learning difficulties/disabilities, domestic violence, ‘implacable hostility’ and ‘parental alienation’
She appears at all levels of the Family Court, (including the High Court) as well as appearing as necessary in the Court of Appeal.
From this work in the Family Court she has a developing interest in Mental Health and Court of Protection – Health and Welfare matters.
She provides representation pro bono in approximately 1 – 2 cases per annum through her membership of the Bar Pro Bono unit.
Sarah is trained as a Family Mediator, specialising in Children issues.

Public Law Children
Sarah is an expert in dealing with care proceedings involving the most serious of issues – in particular, serious non-accidental injury, sexual abuse, neglect, mental health issues and learning difficulties/disabilities.
Re U  – Care proceedings involving a very serious and rare C2 (hangman) fracture of the vertebrae in a 2-year old boy, which was the 7th fracture sustained over a 9-month period. No other concerns about the family, with two older sisters who were receiving excellent parenting. The hospital and Local Authority were convinced that these were non-accidental injuries.
Representing the mother, (led by Darren Howe QC) who speaks very little English, to assist her understanding of the medical evidence. Analysis of that medical evidence undertaken to ensure the right questions of instructed experts were asked to enable full challenge to be made to the Local Authority’s assertion that the injuries must be NAI.
Despite the seemingly obvious conclusion that the most likely explanation for the fractures was NAI, with the right questions being asked of the right experts it was ultimately discovered that the child suffered from a very rare form of osteogenesis imperfecta. The family were immediately re-united.
Re W  – Care Proceedings in respect of serious allegations of sustained, inter-generational sexual abuse made by the now adult daughters of the parents. Both parents alleged to have been abusers, with the mother also failing to protect. The father committed suicide in the weeks before the matter was due to be heard as a fact-finding hearing.
Representing the subject children (half-siblings of the adult witnesses). Serious findings against the mother sought by the Local Authority. Analysis of the adult daughter’s evidence required.
The Mother vehemently denied the serious allegations against her, which resulted in the very vulnerable young women giving evidence. Skilled cross-examination of them was required to enable the court to have the best possible evidence to determine the findings sought.
Private Law Children
Sarah has extensive experience in dealing with the whole gamut of cases within the private law field. In particular cases involving domestic violence, sexual abuse and non-accidental injury as well as those matters which involve 'implacable hostility' and ‘parental alienation’
She also has experience of and is interested in cases of child abduction (both international and within the UK) and applications by a transgender parent to re-establish relationships between them and their child(ren).
Court of Protection – Health & Welfare
Sarah is increasingly involved in cases in the Court of Protection which have begun life in the Family Court. She represents Local Authorities, family members and litigation friends
Re F  – A now 18-year old, severely brain damaged at 4 four weeks of age having been shaken by his mother, lives in residential care, with educational provision. Representing his father who was blameless in the injuries sustained all those years ago but who struggles to accept that he is unable to care for his son at home and criticises the care he is receiving as well as wishing for there to be more contact for both himself and other close family members.
Managing the father’s expectations as well as ensuring that the long-term care arrangements for his son were the right ones were key to ensuring that the very important family relationships are maintained into the future.
Many of Sarah’s cases in the Family Court involve parents with mental health difficulties. She is adept at dealing with such issues and is developing a keen interest in assisting such clients with cases being heard in the First Tier Tribunal (Mental Health)
Re H & L  – In care proceedings – a Fact-Finding representing a mother with significant mental health difficulties - single parent to her children, now aged 10 and 3. Concerns about general neglect but no suggestions of physical harm. 3-year old presents at hospital with extensive facial bruising and two days later with significant bruising to his genitalia. Mother has a new and unknown partner.
The mother due to mental health issues struggled to actively participate in the proceedings– the Local Authority alleged either she, new partner or father caused the injuries. The medical evidence was somewhat conflicting and required challenge.
During the course of giving evidence, mother took an overdose of her anti-depressant medication over the lunch adjournment. When the case resumed once she was discharged from hospital she refuses to continue with her evidence. Legal argument as to what inferences (if any) the court could draw from such refusal.
