Information on adoption certificates
There is a separate index of adoptions which was introduced in 1927. The information shown always refers to the adopted name of the child.
The indexes vary in the amount of information they give, dependent on the year in which the adoption took place.
Application for a certificate should be made to the Adoptions Section of the General Register Office. Further details can be found at https://www.gov.uk/ by entering the search term "adoption certificate."
