United Kingdom is a party to the Hague Apostille Convention (in force since 24 January 1965). A U.S. public document bound for United Kingdom needs a single apostille from the competent authority of the state that issued or notarized it, or from the U.S. Department of State for federal documents. No embassy or consular legalization is required, and United Kingdom's authorities cannot demand one.
Ratified 1964-08-21; in force 1965-01-24 (HCCH).
The route, step by step
- Identify the issuing office
State or local signature → that state’s competent authority. Federal signature → U.S. Department of State. How to tell.
- Prepare the right version
Certified copies for vital and court records; complete notarization for private documents. Preparation checklist.
- Request the apostille
Name United Kingdom as the destination on the request form so the office issues an apostille (not an authentication certificate).
- Translate if required
Confirm with the receiving office in United Kingdom whether a translation is needed and by whom it must be made.
Using U.S. documents in United Kingdom
The UK accepts U.S. apostilles for the relatively few procedures that need them: marriage and civil partnership (apostilled divorce decrees and death certificates of former spouses where the register office asks; no single-status affidavit is required for U.S. citizens, though some registrars request a sworn statement), probate of U.S. wills and grants, company registration (apostilled certificates of good standing and incumbency for UK subsidiaries and bank accounts) and professional registration (certificates of good standing for the GMC, NMC, SRA and others, though most rely on primary-source verification).
No translation is needed for English documents. UK immigration (visas, settlement, citizenship) generally does not require apostilles on U.S. documents; the Home Office verifies through its own channels. Property conveyancing and litigation commonly require apostilled, notarized POAs. The UK issues its own apostilles through the Foreign, Commonwealth and Development Office for documents heading the other way.

United Kingdom-specific points
- Apostilles are usable in UK overseas territories such as Bermuda and Gibraltar (Japan MOFA list).
- English-language US documents need no translation.
