A bank, university or overseas authority may ask for a copy of your passport, degree, company document or proof of address to be “certified” or “notarised”. The distinction between certified copies versus notarised copies can determine whether your paperwork is accepted first time or returned just before a deadline.

The wording matters because these are not always interchangeable terms. A certified copy is usually intended to confirm that a copy matches an original document. A notarised copy is certified by a Notary Public, using formal notarial procedures and a notarial seal. For documents going abroad, that additional formality is often precisely what the receiving authority expects.

What is a certified copy?

A certified copy is a photocopy, scan or printout that an authorised person has compared with the original and confirmed to be a true and complete copy. The certification commonly includes a statement such as “I certify that this is a true copy of the original seen by me”, together with the certifier’s signature, name, professional status and date.

In the UK, the person who can certify a copy depends on the organisation receiving it. A solicitor, Notary Public, accountant, doctor, teacher, bank official or other professional may be acceptable in some circumstances. However, the list is set by the recipient, not by a general rule that applies to every document.

For a routine UK-based application, a standard certified copy may be sufficient. Examples include identity checks for a financial institution, a professional membership application or a domestic administrative process. The recipient may provide exact wording and specify who is permitted to certify the document.

A certified copy does not automatically carry international authority. It is evidence that someone has seen an original and compared it with the copy, but it may not provide the level of verification required by a foreign government department, court, property registry or overseas bank.

What is a notarised copy?

A notarised copy is a copy certified by a Notary Public. A notary is a specialist legal professional authorised to authenticate documents for use outside England and Wales. Before certifying a copy, the notary will normally inspect the original document, satisfy themselves as to its nature and compare it carefully against the copy.

The notarial certificate records the notary’s formal act. It is signed and sealed, and may describe the document presented, the date and place of notarisation, and the capacity in which the notary is acting. This creates a recognisable record for overseas recipients, which is why foreign authorities regularly request notarised copies rather than ordinary certified copies.

A notary may also need to verify the client’s identity, address and purpose for the document. If the document is corporate, further checks can be required, such as confirming the company’s existence, the authority of a director or attorney, and the validity of supporting board resolutions. This is more than a signature on a photocopy. It is a formal professional act designed for international reliance.

Certified copies versus notarised copies: the practical difference

The key difference is not simply the stamp. It is the level of formality, the professional status of the person certifying the copy and the use for which the document is intended.

An ordinary certified copy may be quick and entirely appropriate where a UK recipient has requested one. A notarised copy is generally more suitable where the receiving organisation is overseas, where the instructions expressly say “notarised”, or where the document will need an apostille or consular legalisation.

A notarised copy can often meet a request for a certified copy, provided the recipient has not imposed a particular format or named a different authorised person. The reverse is not always true. A copy certified by a professional who is not a notary may be rejected where a foreign authority requires a notarial seal or needs the document to proceed through legalisation.

Cost and preparation can differ too. Standard certification is usually a narrower task. Notarisation involves identity checks, review of the original, consideration of the foreign jurisdiction’s requirements and the creation of a formal notarial certificate. Where the process must be completed correctly for an overseas transaction, that extra work helps prevent a much more expensive delay later.

When is notarisation likely to be required?

The overseas recipient’s written instructions should always be the starting point. The word “notarised” is a clear indication, but requirements can also be implied by a request for an apostille, legalisation or a document suitable for presentation to a foreign authority.

Notarised copies are frequently requested for passport copies supporting overseas property purchases, immigration or visa applications, university qualifications, marriage documentation, powers of attorney and foreign bank compliance. Businesses may need notarised copies of certificates of incorporation, memoranda and articles, board resolutions, shareholder documents or authorised signatory identification.

Requirements vary sharply by country and even by institution. A US organisation may accept a notarised copy in a format that differs from a Spanish notary, a UAE authority or a Chinese government body. Some recipients require the original document to be notarised, not a copy. Others require a certified translation alongside the notarised document. Assuming that one country’s process will work elsewhere is a common cause of rejection.

Apostille and legalisation: a separate step

Notarisation is often the first stage, not the final stage. If a document is for use in a country that recognises the Hague Apostille Convention, the notary’s signature and seal may need an apostille from the UK authorities. The apostille confirms the authenticity of the notary’s signature and capacity. It does not confirm that the contents of the underlying document are true.

For countries outside the Apostille Convention, the document may require further consular legalisation after the apostille. The precise route can depend on the destination country, document type and receiving authority. Countries such as the UAE, Qatar, Saudi Arabia and China can have specific legalisation processes, and requirements may change.

This distinction is crucial. Asking for a notarised copy when an apostilled notarised copy is required can leave a document incomplete. Equally, arranging an apostille for a standard certified copy may not be possible or useful if the certification was not completed by an appropriate official. The correct sequence should be confirmed before an appointment is booked where time is tight.

How to prepare for a copy certification appointment

Bring the original document wherever possible. A notary cannot normally certify a copy merely from another copy, scan or photograph. Ensure the copy includes every page, including blank pages where they form part of the document, and that no text, stamps, security features or photograph details are cut off.

You should also bring current photographic identification and proof of your residential address. For corporate documents, have the latest Companies House details, constitutional documents and evidence of signing authority available. If the request comes from an overseas lawyer, bank or authority, provide their instructions in full. A single sentence in an email can reveal whether a basic notarial copy, an apostille, translation or further legalisation is needed.

Do not alter, laminate or separate documents unless the recipient has specifically instructed you to do so. Some documents, particularly certificates and academic records, have security features that need to be visible. If there is any doubt about whether an original must be notarised, rather than a copy, ask the receiving authority before proceeding.

Common mistakes that delay acceptance

The most frequent problem is relying on a generic request without checking the recipient’s exact wording. “Certified” may be enough for one organisation but inadequate for another. A second problem is presenting an incomplete copy, particularly a passport copy that omits the reverse side or a corporate document missing a schedule.

Clients also sometimes arrange notarisation without allowing for apostille or embassy legalisation. This can be particularly difficult when a property completion, visa submission or overseas corporate filing has a fixed date. Starting with the destination country and end recipient allows the document to be prepared in the right format from the outset.

White Horse Notary Public can review the purpose of a document, complete notarial certification and advise on the likely apostille or legalisation route for overseas use. For urgent matters, having the original documents and recipient instructions ready before your appointment will make the process faster and more reliable.

The safest approach is simple: treat the receiving authority’s requirements as the rule, not the label used on a form. A properly prepared notarised copy may save repeated appointments, courier costs and the frustration of an overseas rejection when the document is needed most.
