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.

How it works

Click on ‘Start now’ below to complete the request form. After submitting the form you will receive an email confirmation that we have received it.

Following receipt of your request, we will carry out a search of our records based on the information submitted. If we find no evidence of British naturalisation, we will send you a letter signed in wet ink confirming no evidence has been found. The letter will be sent by Royal Mail and will not be tracked. There is a charge of £27.15 GBP for this service, covering the search and the letter.

This letter is valid for 1 year from the date of issue.

If you need more than one copy of the letter you will need to fill in this form again.

We will conduct the search and confirm the outcome within 16 working days of payment.

Please note that we do not issue refunds if we do find evidence or if you provide incorrect information.
