If you are using a UK document abroad, you may be asked to provide a certified copy or have the document certified before it can be accepted. This can feel confusing, especially when the document is already valid in the UK.
Foreign authorities ask for certification because they need reassurance that the document is genuine, complete and suitable for international use. A scan, photocopy or downloaded PDF may not be enough.
What certification means
Certification is a formal confirmation added by a UK solicitor or Notary Public. It usually confirms that a copy is a true copy of the original, or that a document has been checked and prepared for overseas use.
The solicitor or notary applies their signature, stamp or seal to the document. This creates a verifiable signature that can then be legalised for use abroad.
Certification does not change the content of the document. It confirms the document’s status or the accuracy of the copy.
Why the original document is not always enough
Some UK documents can be legalised as originals, especially official civil records such as birth, marriage and death certificates issued by a registry authority.
Other documents cannot go directly through the process because they do not carry a government signature, seal or stamp that can be verified.
This is common with passport copies, school letters, medical reports, powers of attorney, private agreements, employer letters and many business documents.
Why scans and PDFs are often rejected
Many UK documents are now issued digitally. A PDF may be perfectly acceptable for everyday use in the UK, but an overseas authority may not be able to confirm where it came from or whether it has been changed.
A printed PDF usually needs a solicitor or Notary Public to certify it before it can be legalised.
This is especially important for bank statements, school reports, employer letters, medical documents and online company records.
Solicitor certification vs notary certification
In many cases, solicitor certification is enough. A UK solicitor can certify copies, witness signatures and prepare documents for legalisation.
Some countries or authorities specifically ask for notarisation by a Notary Public. This is often the case for legal documents, powers of attorney, property matters, certain business documents and some civil-law jurisdictions.
The correct choice depends on what the receiving authority has requested. If they ask for a notarised document, solicitor certification may not be accepted.
Documents that often need certification
Common documents that may need certification include passport copies, driving licence copies, school records, degree copies, employment letters, medical reports, bank statements, proof of address documents, powers of attorney and company documents.
The exact requirement depends on the document type, destination country and reason for submission.
Checking the requirement before arranging certification helps avoid paying for the wrong process.
Certification before legalisation
Certification is often the step that makes a document suitable for legalisation.
Once the solicitor or notary has signed and stamped the document, the FCDO can authenticate that professional’s signature. The legalised document can then be presented to the overseas authority.
For countries outside the Hague Apostille Convention, embassy or consular attestation may also be required after the UK legalisation stage.
How to avoid delays
Before certifying a document, confirm whether the receiving authority wants the original, a certified copy, solicitor certification, notary certification, translation or embassy attestation.
Also check whether the document needs to be recent. Some authorities only accept documents issued within the last three or six months.
