Most holidaymakers never need to think about apostilles. But if you are moving abroad, applying for a long-stay or work visa, getting married overseas, or enrolling children in a foreign school, you will likely be asked to produce a birth certificate, marriage certificate or degree that a foreign authority can trust is genuine. That is what an apostille does — and getting it wrong, or leaving it too late, is one of the most common reasons long-stay visa applications stall.
What an apostille actually is
An apostille is a standardised certificate, issued by a designated authority in the country that produced the original document, confirming that a public document is genuine — that the signature, seal or stamp on it is real. It does not verify the content of the document itself, only that it was issued by a legitimate authority. The system exists under the 1961 Hague Apostille Convention, which around 120 countries and territories have signed, including the UK, the US, most of the EU, Australia and Japan.
Once a document carries an apostille, any other country that is also party to the Convention must accept it as authentic without further legalisation. Before the Convention existed — and still today for documents destined for non-member countries — the process was far more cumbersome, often requiring sign-off from multiple government departments and the destination country's embassy.
Which documents commonly need one
- Birth and marriage certificates — for visa applications, dual citizenship claims, or registering a marriage or birth abroad.
- Educational certificates and degrees — for work visas, professional licensing, or university admission overseas.
- Police clearance certificates — a near-universal requirement for long-stay work and residence visas.
- Powers of attorney and company documents — for buying property abroad, opening a business, or handling affairs from a distance.
- Adoption and custody documents — where a child is travelling or relocating with only one parent or a guardian.
Short holidays essentially never require an apostille. It becomes relevant almost exclusively for moves, long-stay visas, cross-border legal matters and major life events taking place in another country.
Does the destination country need Hague membership?
The apostille system only works between countries that are both party to the Convention. If your destination is not a member — a number of countries in Africa, the Middle East and parts of Asia sit outside it — your document instead needs full consular legalisation: authentication in your home country, followed by certification at the destination country's embassy or consulate. This process takes longer and often costs more, so check your destination's status before assuming an apostille alone will suffice.
How to actually get an apostille
In the UK
Apostilles are issued by the Legalisation Office, part of the Foreign, Commonwealth & Development Office. Applications can be made online, with documents posted in or, in some cases, submitted via a same-day premium service in London. Processing by standard post typically takes around two weeks, though this varies with demand.
In the United States
Apostilles for documents issued at state level (most birth and marriage certificates) are issued by the Secretary of State's office in the state that issued the original document — not a single federal office. Federally issued documents go through the US Department of State instead. Processing times and fees vary considerably by state.
Elsewhere
Most Hague Convention countries designate a specific national or regional authority — often the foreign ministry, a court system, or a notarial body. A web search for "[country] apostille authority" combined with the relevant government domain is usually the fastest way to find the correct office; avoid third-party sites that charge a markup simply to point you to the right government page.
Practical timing and cost
Processing an apostille typically takes anywhere from a few days to several weeks, depending on the issuing country, whether you use a premium service, and current demand. Costs are usually modest — a flat government fee per document, plus postage — though some countries' premium or expedited services carry a meaningfully higher price. Because visa and residence-permit applications are frequently rejected or delayed for incomplete documentation, most immigration advisers recommend starting the apostille process at least four to six weeks before you need the finished document, and considerably earlier if you also need the underlying certificate reissued or translated.
Translations and certified copies
An apostille certifies the origin of a document — it does not translate it. If your destination country requires documents in its own language, you will typically need a certified translation in addition to the apostille, and some countries specify that the translation itself must also be apostilled or notarised. Get the order of operations right: in most cases, apostille the original first, then have a certified translator produce a translation of both the document and the apostille certificate. Ask the receiving institution — an embassy, university or employer — exactly what format they require before paying for translation work, since requirements vary and redoing a translation is a common and avoidable expense.
Common mistakes travellers make
- Leaving it until the visa deadline is close. Apostille and legalisation processes are among the slowest parts of a visa application, and rushing tends to be expensive.
- Apostilling a photocopy rather than a certified original. Most issuing authorities require the original document or a copy already certified by a notary or the original issuing body.
- Assuming an apostille from one document type covers a related one. A marriage certificate apostille does not cover a birth certificate — each document generally needs its own.
- Not checking whether the destination country is a Hague member. Sending a document for an apostille when full consular legalisation is actually required wastes time and money.
Frequently asked questions
Do I need an apostille for a normal holiday?
Almost never. Apostilles matter for long-stay visas, relocations, overseas marriages, education and legal matters — not short tourist trips, where a standard passport is all that's required.
How long does an apostille take to obtain?
It varies widely by country and document type, from a few days with an expedited service to several weeks by standard post. Build in a comfortable buffer — at least four to six weeks — ahead of any visa or legal deadline.
What if my destination country isn't part of the Hague Convention?
You will need full consular legalisation instead: certification in your home country followed by authentication at the destination country's embassy or consulate, which usually takes longer than a standard apostille.
Can I apostille a document myself, or do I need a solicitor?
In most countries you can apply directly to the designated government authority yourself, without a solicitor. Some people use legalisation agencies for convenience or speed, but this adds cost and is not a legal requirement.
