Notarised translation, Apostille and legalisation are often mentioned together, but they are not the same thing. Each one refers to a different step in preparing documents for official, legal, academic, immigration, business or international use.
A certified translation normally includes the translated document and a written statement confirming that the translation is accurate and complete to the best of the provider's knowledge. A notarised translation may involve a notary public confirming a signature, declaration or document-related act. An Apostille is a form of legalisation used to authenticate certain public documents for use abroad. Legalisation is the wider process of verifying a public signature, seal or stamp so that the document can be recognised in another country.

The right workflow depends on the receiving authority, destination country, document type, language pair and purpose. A university, court, civil registry, ministry, bank, notary, solicitor, consulate or foreign authority may each ask for a different format.
LinguaVox UK provides certified translation services and related document translation services. We do not treat certified, sworn, notarised, apostilled and legalised as interchangeable terms. Clients should check the exact requirement before ordering.
Understanding notarised translation, Apostilles, and legalisation in the UK
In the UK, a certified translation is often enough for many administrative, academic, professional and immigration-related procedures where the receiving body accepts that format. The translation normally includes a certification statement, date, provider details and contact information.
A notarised translation is different. Notarisation usually involves a notary public, often where a document, signature or declaration needs to be formally witnessed or authenticated. This may be relevant for documents intended for use abroad, company documents, powers of attorney, declarations, legal paperwork or transactions where a foreign authority has requested notarial involvement.
An Apostille is a certificate attached to a document after the relevant UK authority has checked whether a public signature, seal or stamp can be verified. It is commonly requested when a UK document must be used in another country. Depending on the document, the Apostille may relate to the original document, a notarial act, a solicitor-certified copy or another public signature.
Legalisation is the broader authentication process. In many cases, UK documents are legalised through an Apostille. In some destination countries or procedures, further consular or embassy steps may also be requested. These requirements should be checked before translation begins, because the order of steps can matter.
When do you need a notary, Apostille, or legalised document?
You may need a notary, Apostille or legalisation when documents are used abroad for marriage, civil registry procedures, residence, nationality, adoption, inheritance, court proceedings, property transactions, company formation, powers of attorney, tenders, professional registration, university admission or cross-border business.
The requirement does not depend only on the document type. It also depends on the destination country and receiving authority. A birth certificate for use in Spain may follow a different workflow from a company document for Germany, a power of attorney for Italy, a university record for France or a business document for Portugal.
In some cases, the original document should be apostilled before translation. In other cases, the translation or a notarial certificate may need a later authentication step. Some authorities may require a sworn translation in the destination country rather than a UK certified translation. For country-specific context, read Sworn translation in Spain, France, Germany, Italy, Portugal and Greece.
Apostille and legalisation requirements are not translation services in themselves. They are authentication steps. LinguaVox can translate the document where a certified translation is suitable, but the client should confirm notarial, Apostille or legalisation requirements with the receiving authority, a notary, solicitor or relevant official service.
Essential checks to make before ordering an official translation
Before ordering a translation for official or international use, check where the document will be submitted, which country will receive it, whether the original document needs an Apostille, whether the translation itself must be notarised, whether a sworn translator is required and whether digital delivery is accepted.
Ask the receiving authority for written instructions whenever possible. Terms such as "official translation", "certified translation", "legalised translation" or "notarised translation" can be ambiguous if the authority does not define the exact format it expects.
Send complete and legible documents. Stamps, seals, signatures, handwritten notes, reverse sides, attachments and marginal comments may affect the translation. If an Apostille is already attached to the original, it may also need to be translated depending on the receiving authority's instructions.
You should also check timing. Apostille, notarisation, courier delivery, printed copies and foreign-authority requirements can add time to the process. If a document is needed urgently for a court, visa, property transaction, university, marriage abroad or company procedure, confirm the full workflow before the translation starts.

Frequently asked questions
What is the difference between a notarised translation, an Apostille, and document legalisation in the UK?
A certified translation confirms the translation. Notarisation usually involves a notary public. An Apostille or legalisation authenticates a public signature, seal or stamp for international use.
When should I verify if my documents need to be notarised or legalised with an Apostille before ordering?
You should verify this before ordering whenever the document will be used abroad, submitted to a foreign authority or linked to legal, civil registry, property, company, academic or immigration procedures.
Do Apostille and legalisation requirements change depending on the destination country or receiving authority?
Yes. Requirements can change depending on the destination country, receiving authority, document type and procedure. Written instructions from the receiving body are the safest reference.
Can your translators advise me on the correct legalisation and certified translation workflow for my paperwork?
LinguaVox can review your translation instructions and explain common workflows, but notarial, Apostille and legalisation requirements should be confirmed with the receiving authority, notary, solicitor or official service.
Which official translation service from LinguaVox UK is the right fit for my legalised documents?
Start with certified translation services and explain where the document will be used. If notarisation, Apostille or legalisation is required, those steps should be checked separately before confirming the translation workflow.
