A bank, overseas lawyer, university or government authority may ask for a “certified copy” of your passport, driving licence or proof of address. The request can appear simple, but knowing how to certify identity documents correctly matters: an incorrect statement, an unsuitable certifier or an expired document can lead to rejection and costly delay.

The right approach depends on who has requested the document and where it will be used. A UK organisation may accept a certified copy from a professional such as a solicitor or accountant. For use abroad, a foreign authority will often require notarisation, and sometimes an apostille or consular legalisation as well. Establishing that requirement before an appointment is the quickest way to avoid doing the process twice.

What does certifying an identity document mean?

Certifying an identity document means that an authorised professional has seen the original document and confirms that the copy is a true likeness of it. They do not issue a new passport or confirm every fact recorded by the issuing authority. Their certification confirms that the copy presented matches the original they inspected.

The certifier will normally write or stamp a statement on the copy, sign and date it, and provide their name, professional capacity and contact details. The wording required can vary. Some recipients prescribe the exact form of words, while others simply ask for the copy to be certified as a true copy of the original.

A certified copy is different from a witnessed signature. It is also different from an identity check for anti-money laundering purposes. Each process has a distinct purpose, and substituting one for another can cause a recipient to refuse the document.

First, check what the receiving organisation requires

Before arranging certification, read the recipient’s instructions carefully. This is particularly important for foreign banks, property transactions, immigration applications, probate matters and overseas company filings. Ask whether they require a certified copy, a notarised copy, or the original document to be presented.

You should also confirm whether the recipient has rules about the person who certifies the document. Some UK bodies publish a list of accepted professions. Others insist on a solicitor or notary public. An overseas authority may specifically require a notary’s signature and seal because it needs a formal record that can be recognised outside the UK.

Other practical points to check include whether the certification must be recent, whether colour copies are required, and whether proof of address must be dated within a particular period. If the document will be used internationally, ask whether it needs an apostille from the Foreign, Commonwealth and Development Office or legalisation by the destination country’s consulate. Requirements are set by the receiving body and country, not by the certifier.

How to certify identity documents: the practical process

The process is straightforward when the documents and instructions are ready. Start by making clear, complete copies of the original identification. Colour copies are often preferable for passports and photocard driving licences because security features, photographs and stamps are easier to see. Every page requested by the receiving organisation should be copied, including observation pages or pages containing relevant visas where applicable.

Take the original document to the appointment. A professional cannot usually certify a copy merely from a scan, photograph or another copy, because they need to compare it with the original. The document should be current, legible and undamaged. If a passport is expired, do not assume it will be accepted simply because the photograph remains recognisable.

Provide the recipient’s instructions, especially if specified wording is required. The certifier can then assess whether they are able to meet the request and apply the right certification. A notary may need to retain a copy, record details of the identity check and ask questions about the proposed use of the document. This is a normal part of professional verification, particularly where a document will be relied on abroad.

Once signed and sealed where appropriate, send the certified document by the method requested. Do not alter it, add notes, laminate it or separate pages that have been bound or sealed together. If an apostille or legalisation is required, the original notarised document may need to follow a particular handling route, so keep the document secure.

Who can certify a copy in the UK?

For a domestic request, the receiving organisation may accept certification from a range of regulated professionals. Depending on its policy, this could include a solicitor, notary public, chartered accountant, doctor, teacher, bank official or religious minister. Acceptance is never automatic. A professional may be qualified in their field but not appear on the recipient’s approved list.

For documents intended for use overseas, a notary public is commonly the appropriate choice. Notaries deal specifically with documents that must be accepted in other jurisdictions. They can verify identity, certify copies, witness signatures and prepare notarial certificates in the form required for international use. Their signature and seal can then be authenticated through an apostille or, where necessary, consular legalisation.

A commissioner for oaths and a solicitor can perform certain certification and witnessing functions, but their work is not interchangeable with notarial work. If the document is going abroad, choosing the lowest-cost local option without checking the requirement can create a false economy. The document may later need to be notarised afresh.

Certification, notarisation and legalisation are not the same

These terms are often used loosely, but they describe separate stages.

A certified copy confirms that a copy matches the original. Notarisation is a formal notarial act carried out by a notary public, who verifies identity and capacity, examines the document and applies their signature and seal. The notary may also prepare a notarial certificate that explains precisely what they have done.

An apostille is an official certificate attached to a UK public document or notarised document for use in countries that participate in the Hague Apostille Convention. It authenticates the signature and seal for international recognition. It does not independently verify the underlying contents of a passport or agreement.

Consular legalisation is an additional stage required by some countries outside the apostille system. After the apostille, the relevant embassy or consulate may authenticate the document for use in its jurisdiction. Translation may also be required if the receiving authority does not accept English-language documents.

The correct route can therefore range from a simple certified copy for a UK employer to notarisation, apostille, legalisation and translation for an overseas authority. It depends entirely on the destination and purpose.

Documents commonly presented for certification

Passports and UK photocard driving licences are the most common identity documents. National identity cards, biometric residence permits, birth certificates and marriage certificates may also be requested, depending on the transaction. For proof of address, recipients frequently ask for recent utility bills, council tax statements or bank statements.

Be careful with electronic statements. Some organisations accept a printout of an online statement if it is certified against the original electronic record shown on your device or supplied directly by the bank. Others require a paper statement issued by the institution. A professional should not certify an electronic document in a way that suggests they have verified its source unless they are satisfied as to its authenticity.

For company matters, the identity documents of directors, beneficial owners or authorised signatories may be required alongside company registers, certificates of incorporation or board resolutions. These personal and corporate documents should be reviewed together so that certification, notarisation and legalisation are coordinated.

Avoid the mistakes that cause rejection

The most frequent problem is using the wrong person to certify the document. The next is presenting an unclear copy, a document that has expired, or certification that does not include the required wording, date, signature and professional details. A recipient may also reject a certification that is too old, even where the underlying passport remains valid.

Do not sign or date the certifier’s statement yourself. Nor should you assume that a stamp alone will be sufficient. A properly prepared certification must show who performed the check and when. If a copy contains multiple pages, ask whether each page must be certified or whether the pages should be securely bound and certified as a single set.

Time pressure is another risk. Apostille and consular processes add stages beyond the notarial appointment, and overseas offices may have their own processing times. Starting early is sensible, but urgent cases can often be managed efficiently when the destination country, document type and deadline are known from the outset.

Getting the process right without unnecessary delay

For sensitive identity documents and international requirements, accuracy at the first stage protects the whole transaction. A notary can assess the receiving authority’s instructions, verify your original documents and advise whether further authentication is likely to be needed. White Horse Notaries provides a fast, carefully managed service for clients who need certified, notarised or legalised identity documents in London and for overseas use.

Bring the originals, the recipient’s written requirements and any deadline to the first conversation. With those details in hand, the certification can be prepared in the right form and your documents can move forward with far less risk of rejection.
