The Department for Education (DfE) has now introduced new adoption legislation (the adoption Order 2013) and revoked the old adoption legislation (the ‘designated list’). Ghana is not included in the new adoption Order 2013. Domestic adoption orders made in Ghana on or after 3 January 2014 will no longer be automatically recognised in England and Wales and Scotland and these children will no longer have an automatic entitlement to British nationality through their adoptive parents. If British prospective adopters wish to adopt in Ghana and then return to the UK with the child, they will need to complete the domestic adoption process, apply for a UK visa for the child and then apply for a UK adoption order on their return to the UK.
You should contact UK Visas and Immigration and the Department for Education for more information.
