Notarisation and Apostille Services for Certificates of Naturalisation

A Certificate of Naturalisation confirms an individual’s citizenship in a specific country, often following a period of residence. In the UK, foreign residents can apply for citizenship through the Home Office.

At Wharf Notaries, we provide efficient and professional legalisation services for your documents.

Notarising a British Certificate of Naturalisation

A qualified notary public can verify and certify your Certificate of Naturalisation, ensuring it is recognized internationally. This process authenticates the certificate’s validity, attaching a notarial certificate as official proof. If needed for use abroad, we can also obtain an apostille to complete the legalisation.

Notarisation adds credibility, making your certificate suitable for legal and administrative purposes, such as immigration or employment overseas.

At Wharf Notaries, we streamline this process and are ready to assist with any questions, providing clear guidance on services and associated costs.

While an apostille isn’t needed for a UK passport application, some international organizations may require an apostille along with notarisation.
