Family justice is concerned with keeping children safe and helping families resolve disputes. It includes cases on protecting children, who children live with and how they spend time with their family, as well as divorce, adoption and associated financial arrangements. In this report we focus on the two categories of family justice cases that involve legal disputes over children: ‘public law’ and ‘private law’. Public law cases are brought by local authorities to protect a child from harm. Private law cases involve parental disputes, such as the living or contact arrangements for their child. These two types of cases are among the most costly and time-consuming family court cases as they can involve vulnerable children, substance misuse and domestic abuse. Family justice involves the judiciary and several central government organisations and public bodies working together. The Department for Education (DfE) and the Ministry of Justice (MoJ) are the lead policy departments for public law and private law, respectively. Local authorities are statutorily responsible for safeguarding children and social work. HM Courts & Tribunals Service (HMCTS) is responsible for administration of the courts and judges and magistrates hear the cases. The Children and Family Court Advisory and Support Service (Cafcass) and its equivalent in Wales, Cafcass Cymru, advise the courts on what is safe for children and in their best interests. Independent solicitors and barristers represent families at court and may be funded by legal aid.
