Document Legalisation and Apostille Services in the UK

Document legalisation is the process that makes a UK document valid for use in another country, and for most destinations it comes down to one thing: an Apostille Certificate attached by the FCDO Legalisation Office. This page explains which documents qualify, when a notary or solicitor has to certify them first, how the paper and electronic routes differ, and what to do if the Foreign, Commonwealth and Development Office rejects your paperwork. If you are starting from scratch, the overview of UK apostille and document legalisation services covers the full picture.

What legalisation means, and where the apostille fits

Legalisation, sometimes spelled “legalization” in American English, is the official confirmation that a signature, stamp or seal on a UK document is genuine. The body that carries this out is the Legalisation Office, part of the Foreign, Commonwealth and Development Office (FCDO): according to gov.uk (checked 14 September 2026), it checks the signature, stamps and seals on a document and then attaches an Apostille Certificate. Once the apostille is attached, the document is accepted in the countries covered by the Hague Apostille Convention 1961, the treaty signed on 5 October 1961 that abolished the old requirement for full diplomatic legalisation between member states.

The apostille itself is a separate certificate, usually stapled or bound to the document, that identifies the signing authority, the capacity in which the person signed and the seal on the paperwork. It does not confirm that the contents of the document are true; it confirms only that the official marks on it are authentic. That distinction matters when a foreign authority asks for extra steps, such as a sworn translation, on top of the apostille.

Which UK documents can be legalised, and which cannot

According to gov.uk (checked 14 September 2026), the FCDO can legalise three broad categories of documents: those issued by a UK court with a wet seal, those issued by a public register, and those issued by a government department carrying an official signature. In practice this covers the paperwork people legalise most often: a UK Birth Certificate or UK Marriage Certificate issued by the General Register Office (GRO), death certificates, certificates from Companies House, and official letters from departments such as HMRC.

Documents that do not fall into these categories, such as a Power of Attorney, a commercial contract, a qualification certificate or a copy of a passport, can still be legalised, but only after they have been certified by a UK public official: a Notary Public or a solicitor. This is where Solicitor Certification and notarisation come in. One more restriction is worth knowing before you spend anything: according to gov.uk, documents issued outside the UK cannot be legalised through this service at all. A foreign birth certificate, for example, must be legalised in the country that issued it.

Document type and whether you need a notary

The single most common point of confusion is which documents go straight to the FCDO and which need certification first. The table below gives the typical route for each document type.

If your document is a criminal record check, read the guide to the ACRO Police Certificate before applying, because the issuing format affects whether the FCDO will accept it as signed. When a document needs certification, the notary or solicitor will typically verify the original, attach a covering certificate and sign and seal it; only then does the document become eligible for the apostille.

The legalisation process from certification to apostille

The chain is short once you know which branch your document sits on. For registry certificates the chain has two links: obtain the document, then submit it to the FCDO. For private documents there are three links: certification by a notary public or solicitor, then the FCDO check, then the apostille. The FCDO checks that the signature, stamp or seal on the document matches its records, and if it does, the Apostille Certificate is attached and the document is returned.

Applying is done online. According to gov.uk (checked 14 September 2026), you need the documents to be legalised and a credit or debit card to pay the fee; for the paper-based route by post you also need a return address and access to a printer. The postal route means sending the original document to the Legalisation Office and waiting for it to come back, so most people building in a deadline use a courier both ways or hand the job to a provider.

Paper apostille or e-Apostille

Since 2 September 2022, the UK has also issued apostilles electronically: the FCDO announced the launch of electronic legalisation of public documents on that date, and the digital version is known as the e-Apostille. Instead of a paper certificate attached to a physical document, the e-Apostille is a digital certificate applied to an electronic copy of the document, verified online by the receiving party.

The practical question is not which format is better in the abstract but what the authority in the destination country will accept. Some registries, universities and employers abroad now process e-Apostilles without hesitation; others still expect a paper original with a physical certificate attached. Before choosing the electronic route, ask the organisation that will receive the document whether it accepts a digitally apostilled copy. If there is any doubt, the paper apostille remains the safest default, because it is accepted everywhere the Convention applies.

How long legalisation takes and what it costs

Timing depends almost entirely on the route you choose. The standard FCDO service processes documents in the order they arrive and takes longer than the paid fast-track option; the FCDO publishes an official list of next-day service providers (guidance first published on 1 February 2023, updated 11 September 2026, checked on gov.uk on 14 September 2026), and providers on that list can turn an apostille around within 24 hours. Embassy attestation, where the destination country requires it, adds a further stage with its own processing time set by each embassy.

On cost, there are three separate components to budget for, and they come from different sources. The FCDO charges its own fee per document, published on gov.uk. A notary public or solicitor charges for certification, and these fees vary considerably between firms and cities. If you live outside the UK or are working to a deadline, add return courier postage, and for non-Convention countries add the embassy’s attestation fee. A realistic budget is therefore the FCDO fee plus certification plus postage, with the embassy fee added only when the destination country requires attestation.

A worked example: marrying abroad on a UK marriage certificate

Situation: you were born and married in the UK, and the authorities in your partner’s country have asked for your UK Marriage Certificate and a Certificate of No Impediment, both apostilled, before they will register the marriage.

Steps: first, order a replacement marriage certificate from the GRO if the original is lost, and obtain the Certificate of No Impediment from your local register office. Second, check whether the destination country is a party to the Hague Apostille Convention 1961; if it is, no embassy stage is needed. Third, apply for legalisation online, pay the FCDO fee and post both originals to the Legalisation Office, or pass them to a next-day provider if the wedding date is close. Fourth, if the foreign authority does not read English, order a certified translation of the apostilled documents; the page on certified translation services in the UK explains what a proper certified translation looks like.

Result: two apostilled originals, plus translations if needed, ready to hand to the foreign civil registry. The apostille stage itself is measured in days when a next-day provider is used, so the total timeline is usually driven by how quickly you obtain the certificates and translations rather than by the FCDO.

Embassy attestation for countries outside the Hague Convention

For countries that are not party to the Hague Apostille Convention 1961, an apostille alone is not enough: the document also needs Embassy Attestation. In this chain the apostille is the middle step, not the last one. The document is first certified by a notary public or solicitor where required, then apostilled by the FCDO, and finally submitted to the embassy of the destination country in the UK, which verifies the apostille and adds its own attestation.

Because each embassy sets its own requirements, fees and processing times, the total timeline for attestation can vary widely from one country to another, and some embassies ask for additional copies or translations alongside the apostilled original. The page on which countries require legalisation of documents sets out how destinations differ and where the embassy stage applies. Build the embassy stage into your planning from the start: it is the part of the chain least within your control.

Legalising UK documents while living overseas

Living abroad does not prevent you from legalising a UK document, and in most cases you will not need to travel back. The online application can be completed from anywhere, and the original document travels to and from the FCDO by post or courier. Many people living overseas appoint a UK-based legalisation provider or give a relative or adviser written authority to handle the submission and return postage on their behalf, which removes the risk of an original certificate going missing in international transit.

Two practical points save people the most trouble. First, if a registry certificate has been lost, a replacement can be ordered from the General Register Office and sent directly to whoever is handling the legalisation, so the replacement never needs to pass through your hands. Second, think about the end of the chain before the beginning: if the foreign authority will need a translation, arrange it for the apostilled version, not the bare document. A Power of Attorney for property or banking matters abroad follows the same pattern, with one addition: because it is a private document, it must be drafted and signed in front of a UK notary public before it can go to the FCDO.

When the FCDO rejects a document

Rejections happen, and they almost always trace back to one of a handful of causes. The most common are submitting a photocopy or scanned copy instead of the original, certification that does not meet the standard (for example, a solicitor’s stamp where notarisation was required, or missing wording on the covering certificate), a document issued outside the UK, and seals or signatures that are damaged, faded or otherwise impossible to verify against the FCDO’s records.

There is a financial consequence to getting it wrong: according to gov.uk (checked 14 September 2026), if a document cannot be legalised, the fee is not refunded. That makes a short pre-submission check worth the effort: confirm the document is an original or a properly issued replacement, confirm the certification is the right type for that document, and confirm the signature and seal are legible.

If a rejection does arrive, the Legalisation Office will state what was wrong. The fix is usually straightforward: obtain proper notary or solicitor certification, order a replacement certificate from the issuing registry, or substitute the original for a copy. Once the document is corrected, it is simply submitted again as a new application with a new fee. Nothing is lost permanently; the apostille process has no penalty for resubmission beyond the cost of doing it twice, which is exactly why the pre-submission check pays for itself.
