Since November 2017, approved adopters have been able to inspect the adoption register in their quest for a match: a child whom they would like to adopt and obtain certain information(seehttp://www.breakinglaw.co.uk/2017/10/matching-children-for-adoption.html ) although nothing which would at that stage enable them to identify the child.
The available information is being widened as from 4 October 2018 * and the additional information will comprise the child's first name, their health history and that of their family where available and geographical considerations.
* The law is changed by the Adoption and Children Act Register Search and Inspection) (Amendment) Regulations 2018 SI2018/993.
