Before you order: check your passport route
If your passport was issued outside the UK, ask its issuing authority what it requires for a name change. It may accept a UK deed poll, require translation or legalisation, or use a different national process. Establish that sequence before arranging travel in the new name.
Write down the exact spelling the passport authority will use, including the order of surnames and any transliteration. A consistent plan makes it easier to prepare the deed and explain the link to your existing UK records. See our dual-nationality guide if you hold more than one passport.
