Legalising UK documents is usually a simple process.
[If required] Get documents certified or notarised
A registered UK solicitor may need to certify your documents. (For example, business and educational documents need certification)
Step two is getting UK documents legalised by the FCDO
UK public documents get legalised by requesting confirmation from the UK Foreign, Commonwealth & Development Office (FCDO). They check your documents, including signatures and if public officials are part of their database.
Additional steps are required for some documents – please enquire.
