> In the UK “real name” and “legal name” are just aliases for “your name” which is the identity you’re known by on documents issued by the government and its Home Office, ie your National Insurance record or your UK Passport. Your aliases are not your name unless and until you change that name by deed poll or through marriage / divorce. Your aliases, no matter how well recognized they may be, are not your name.

this is simply not true

this is the official position of the foreign office: https://assets.publishing.service.gov.uk/government/uploads/...
