Request confirmation of no evidence of British naturalisation

Use this service if you:

  • Want us to confirm that we can find no evidence that you or someone else acquired British citizenship through naturalisation up to October 1986
  • Want a signed letter from us confirming this

We can search the British citizenship records up to October 1986 held by The National Archives. If the subject of your request did not obtain British citizenship there will be no record and we will confirm this by issuing a signed letter.

If you require this letter for legal purposes, you will need to get this ‘legalised’ by submitting it to the Foreign, Commonwealth and Development Office Legalisation Service.

Do not use this form for someone born after 1968 or if you want to check whether someone did or did not obtain British citizenship from October 1986 onwards – you must apply to UK Visas and Immigration.

If you meant to request a search for a certificate of British citizenship, you need to use our other service.
