A foreign bank asks for a notarised passport copy. A property lawyer requests a power of attorney. A consulate wants legalised company documents. The immediate question is often: must originals be notarised, or can you provide a copy? The answer depends on the document, the act required and, above all, the rules of the overseas authority receiving it.

For many international matters, an original document does not need to be notarised simply because it is original. However, a notary may need to inspect the original before certifying a copy, witnessing a signature or preparing a notarial certificate. Sending the wrong format can lead to rejection, repeated appointments and missed deadlines, so it is worth confirming the requirement before anything is signed or legalised.

Must originals be notarised in every case?

No. Notarisation is not a blanket requirement for original documents. It is a formal notarial act carried out for a particular purpose, usually so a document can be relied on outside the UK. The receiving organisation may require an original document, a notarised copy, a signature witnessed by a notary, or a document that has been notarised and then apostilled or legalised.

An original birth certificate, degree certificate or Companies House document may be perfectly valid in its own right. Yet an overseas authority may not be willing to accept it without additional evidence of authenticity. In that situation, the authority may ask for a notarised copy, an apostille, or both. The wording of its instructions matters more than a general assumption about what is normally done.

Equally, some documents should not be notarised after they have been signed. A power of attorney, affidavit, declaration or corporate resolution may need to be signed in the notary’s presence. If it has already been signed, it may need to be executed again. Do not sign a document in advance unless the recipient or notary has confirmed that this is acceptable.

When the original must be shown to a notary

The most common reason to bring an original is to obtain a certified true copy. A notary cannot responsibly certify that a photocopy or scan is a true copy of an original they have not inspected. They will compare the copy against the original, check that all pages and relevant markings are present, then attach or endorse a notarial certificate.

This is frequently required for passports, driving licences, utility bills, academic certificates, bank statements and company records. The recipient often does not need your original passport or certificate itself. It needs assurance from an independent legal professional that the copy accurately reproduces the original.

Originals also help establish identity, capacity and authority. If a company director is signing for a business, the notary may need to see original or reliable official evidence of the company’s existence, the director’s position and their authority to sign. For an individual, a current passport and proof of address are commonly required, alongside any supporting documents relevant to the transaction.

There are occasions when a certified copy is not enough. A foreign court, registry, university or immigration authority may insist on the original civil-status certificate, qualification or signed instrument. If the original is required, the question may be whether it needs an apostille or consular legalisation rather than notarisation. These are different steps, and confusing them is a common cause of delay.

Original documents and signature witnessing

Where the task is to witness a signature, the key document is usually the original document being signed. The notary verifies the signer’s identity, ensures they understand the document and, where appropriate, confirms they are signing willingly and with authority.

A scanned document may sometimes be suitable for review ahead of an appointment, but the final version must be agreed before signing. Even a minor change after notarisation can affect whether the notarial certificate remains appropriate. For multi-page deeds and powers of attorney, page numbering, attachments and execution wording should be checked carefully.

When a notarised copy is the right solution

A notarised copy is often the practical option when you need to keep the original safe, use it for several applications or cannot send it abroad. It may be accepted for identity checks, overseas company formation, bank account applications, property transactions and academic or professional verification.

It is not automatically interchangeable with an original. Some recipients specify “original document” and will reject any copy, however carefully certified. Others specify “notarised copy” but also require it to be apostilled. An apostille confirms the authenticity of the notary’s signature and seal for use in a country that participates in the Hague Apostille Convention. It does not independently verify the contents of the underlying document.

If the destination country is not part of that convention, consular legalisation may be required after the notarial step and, where applicable, Foreign, Commonwealth and Development Office authentication. This chain is particularly relevant for documents intended for certain overseas courts, government departments and commercial registries.

Documents issued by public authorities

Public documents need particular care because the correct route varies. A UK birth, marriage or death certificate may sometimes be apostilled directly if it is an acceptable original or official certified copy. A notarial copy may not satisfy a foreign authority that specifically wants an apostille on the certificate itself.

The same principle applies to criminal-record certificates, court documents and Companies House records. Some can be legalised directly; others need additional certification first. University degrees and transcripts can be more complicated, as a university officer’s signature may need verification before an apostille can be obtained.

Do not assume that an old certificate will be accepted merely because it is original. Overseas authorities occasionally require recently issued versions, long-form certificates or documents issued within a set period. A document can be genuine and still fail the recipient’s administrative rules.

Can electronic documents be notarised?

Electronic documents are increasingly common, but acceptance remains destination-specific. A digitally issued document may be valid in the UK and still be unsuitable for a foreign authority that expects a paper original, wet-ink signature or physical stamp.

Remote online notarisation can be a convenient option where the document, jurisdiction and receiving body permit it. It can reduce travel and speed up straightforward matters, particularly where identity checks and electronic signing are accepted. However, it is not a shortcut around the recipient’s requirements. Some authorities will only accept a traditional paper notarial certificate, and legalisation procedures may also dictate the format.

For urgent matters, send the recipient’s written instructions, the destination country and a clear copy of the document for review before booking. This allows the correct process to be identified early, including whether an in-person appointment, wet-ink execution, apostille or consular legalisation is needed.

A practical check before you proceed

Before arranging notarisation, establish what the receiving body has actually requested. Ask whether it needs the original, a certified copy, a notarised signature, an apostille or full legalisation. Also check whether a translation is required and whether the recipient has prescribed wording, a validity period or a preferred form of certificate.

Bring every relevant original to the appointment, even if you believe only a copy will be used. This includes valid photo identification, proof of address and evidence of authority where you are acting for a company, trust or another person. It is usually quicker to inspect documents at the outset than to pause a matter while further evidence is obtained.

White Horse Notaries can review the destination requirements and guide you through notarisation, certified copies, apostilles and legalisation with transparent pricing and a clear timetable. Where an overseas institution’s instructions are unclear, obtaining confirmation in writing is the safest route.

The right question is rarely whether every original must be notarised. It is what the receiving authority needs to accept your document first time – and arranging precisely that, no more and no less.
