Apostille, notary, certification, translation: what is the difference?
If you need to use a UK document abroad, you may quickly come across words such as apostille, notary, certification and translation.
They can sound similar, but they are not the same.
One confirms a document or signature is genuine. Another confirms a copy matches the original. Another prepares a document for use in another language. Getting the wrong step, or doing the steps in the wrong order, can lead to delays.
What is certification?
Certification usually means that a copy of a document has been checked against the original by an authorised person.
A certified copy may be needed when you do not want to send the original document.
Certification may be used for:
- passport copies
- degree certificates
- birth certificates
- marriage certificates
- bank statements
- utility bills
- company documents
- powers of attorney
- professional certificates
The certifier may write that the copy is a true copy of the original, then sign, date and add their professional details.
Who can certify a document?
This depends on who is asking for the document.
A certified copy may need to be completed by:
- solicitor
- notary public
- accountant
- regulated professional
- issuing organisation
- government office
- embassy or consulate
Do not assume any professional can certify your document. Some overseas authorities have specific rules.
What is notarisation?
Notarisation is carried out by a notary public. Notaries are often used for documents that will be sent overseas.
A notary may:
- verify identity
- witness a signature
- certify a copy
- prepare a notarial certificate
- confirm a document for international use
- handle company or power of attorney documents
Notarisation is often required for more formal legal, property, business or international documents.
When might you need a notary?
You may need a notary for:
- powers of attorney
- property documents
- company documents
- overseas legal declarations
- certified copies for foreign authorities
- documents for business abroad
- documents for marriage or inheritance abroad
- documents that need apostille after notarisation
Some documents cannot go straight to apostille in their original form and may need solicitor or notary certification first.
What is an apostille?
An apostille is a certificate attached to a document to confirm that the signature, seal or stamp on it is genuine for use abroad.
It does not confirm that the content of the document is true. It confirms the authenticity of the official signature or seal.
An apostille may be needed for:
- birth certificates
- marriage certificates
- divorce documents
- degree certificates
- police certificates
- medical certificates
- court documents
- company documents
- solicitor-certified copies
- notarised documents
It is often requested by overseas authorities, universities, employers, courts, banks and government offices.
What does an apostille prove?
An apostille confirms things such as:
- the document was signed by a recognised official
- the seal or stamp is genuine
- the certifier or notary has authority
- the document can be recognised for overseas use
It does not translate the document and does not make an invalid document valid.
What is certified translation?
Certified translation means a document has been translated by a translator or translation provider who confirms that the translation is accurate.
It may be needed when the receiving country or organisation does not accept English documents.
Certified translations may be required for:
- birth certificates
- marriage certificates
- divorce documents
- academic certificates
- transcripts
- police certificates
- medical records
- consent letters
- court orders
- bank statements
- employment letters
The translation should usually include translator details, date, signature or certification statement.
Translation is not the same as apostille
A translation changes the language of the document.
An apostille confirms the authenticity of the document, signature or seal.
You may need one, both or neither, depending on the country and purpose.
For example, a university abroad may ask for an apostilled degree certificate and a certified translation. A bank abroad may ask only for a translated proof of address. A visa office may ask for original certificates with apostilles.
The order can matter
One of the most common mistakes is arranging the right services in the wrong order.
A document may need to be:
- Issued or obtained.
- Certified by a solicitor or notary, if required.
- Legalised with an apostille.
- Translated by a certified translator.
- Submitted to the overseas authority.
But this order is not always the same. Some authorities want the translation legalised too. Others want only the original document apostilled before translation.
Always check the exact requirement before starting.
Example: degree certificate for an overseas job
An employer abroad may ask for your UK degree certificate to be verified.
This could mean:
- certified copy of the degree
- solicitor or notary certification
- apostille
- certified translation
- embassy attestation, in some cases
Sending only a scan may not be enough.
Example: marriage certificate for a visa
A spouse visa application abroad may require proof of marriage.
This could involve:
- original marriage certificate
- apostille
- certified translation
- extra copies
- supporting name change documents
- divorce documents from previous marriages, if relevant
If names differ across documents, supporting evidence may also be needed.
Example: power of attorney abroad
A power of attorney for property or legal matters abroad often needs more formal handling.
It may require:
- document drafting
- signature witnessed by a notary
- apostille
- certified translation
- embassy attestation, if required
- local legal review abroad
This is why powers of attorney should not be left until the last minute.
Embassy attestation
Some countries require embassy or consulate attestation after notarisation or apostille.
This is a separate step and may be needed for:
- work visas
- education documents
- business documents
- property documents
- marriage documents
- family documents
- professional licensing
Not every country requires it, but where it is needed, an apostille alone may not be enough.
Which step do you need?
The answer depends on:
- document type
- country where it will be used
- organisation requesting it
- whether the document is original or copy
- language of the receiving authority
- whether a signature needs verification
- whether embassy attestation is required
- whether the document has an expiry period
The safest approach is to ask the receiving authority exactly what format they require.
Questions to ask before preparing documents
Before arranging certification, notarisation, apostille or translation, ask:
- Do you need the original or a certified copy?
- Who can certify the document?
- Is notarisation required?
- Is an apostille required?
- Is embassy attestation required?
- Is certified translation required?
- Should the apostille be translated?
- Does the translation also need certification?
- How recent must the document be?
- Can documents be submitted digitally?
Clear answers can prevent rejected documents.
Common mistakes to avoid
Common problems include:
- thinking certification and apostille are the same
- translating a document before checking apostille rules
- using the wrong certifier
- apostilling a copy when the original was required
- sending scans when originals are needed
- forgetting embassy attestation
- assuming English documents are accepted everywhere
- not checking name differences
- leaving legalisation too late
- not keeping copies of completed documents
Final thoughts
Apostille, notary, certification and translation are different steps, but they are often connected.
Certification confirms a copy or document has been checked. Notarisation involves a notary public and is often used for overseas legal documents. An apostille confirms the authenticity of a UK signature, seal or stamp for use abroad. Certified translation makes the document usable in another language.
Before preparing UK documents for overseas use, check exactly what the receiving authority requires and in what order. This can save time, money and frustration.
