About Sarah

Being described as the calm in a frightening storm has always stuck with me. As a specialist in children law representing clients from diverse backgrounds I strive to ensure my clients remain at the core of the work I do on their cases, by making them feel understood, listened to and fully supported, after all it is their family I am getting through this storm.

Sarah specialises in complex cases involving vulnerable adults and children during care proceedings and family disputes such as children spending time with and/or living with one family member. In this changing world of how families develop and are formed, Sarah has the ability to adapt and change as well as take on new challenges to meet her clients changing needs.

Sarah is particularly experienced in advising and representing children, parents and family members in difficult and sensitive cases which are often life changing for families - for example, where there are issues of parental drug and alcohol addiction, domestic abuse and or a mental health difficulty. Sarah has a reputation for being able to tackle a difficult area in a case such as mental health without being phased by the added complexities. Many cases often involve allegations of sexual abuse or physical harm to children. She handles these highly emotional cases with sensitivity and kindness.

Sarah is also experienced in international and domestic adoption and surrogacy and advising LGBTQ+ families. 

Sarah Richardson has a mixture of fantastic legal knowledge, down to earth common sense, and real sensitivity to be able to work with and represent vulnerable teenagers.

She also advises on:

  • adoption cases both in the UK and internationally
  • abduction cases where a parent wishes to remove children from the UK without the consent of the other parent or other family members
  • forced marriage cases where one or both parties do not consent to the marriage or consent is given under emotional or physical duress, including representing parties on both sides in the High Court
  • deprivation of liberty applications for both children and parents
  • disputes with social workers about assisting families, especially when children have mental health challenges and may also be beyond parental control
  • assisting clients either wanting to be foster carers or who are currently foster carers who are in dispute with the local authority and/or agency

Sarah is an experienced advocate undertaking the majority of her own advocacy including trials giving the client a high standard of service from start to finish of the case.

Sarah is incredibly pragmatic - she gives appropriate advice and isn't afraid to give it, but she also wants to get the right result and do her best by her clients.
