What Is an Apostille? A Simple Guide for First-Time Property Buyers in Spain
The small legal stamp that trips up British and Polish buyers — and how to get one before it delays your purchase
Last updated: 8 September 2026.
An apostille is an official stamp that proves a document from your home country is genuine, so a Spanish notary, bank or tax office will accept it. If you're buying property in Spain and you're not from Spain, you will almost certainly need one — most often on a power of attorney, a criminal-record certificate, or a birth or marriage certificate. Without it, your purchase can stall at the notary's desk.
This guide explains what an apostille is, when you need one to buy in Spain, how to get one in the UK and in Poland, how much it costs, and how it fits together with the sworn translation Spain also requires. No legal jargon — just the steps in the order you'll actually do them.
What an apostille actually is
An apostille is a one-page certificate attached to a public document. It confirms who signed the document, in what capacity, and that the seal or stamp is real. It was created by the Hague Convention of 5 October 1961, which replaced the slow, expensive process of embassy legalisation with a single standardised certificate that every member country agrees to accept.
Both the UK and Spain have been members for decades — Spain since 1978 — and Poland is a member too. That means a UK or Polish document with an apostille is valid in Spain without any embassy step. Brexit did not change this: the Hague Convention has nothing to do with the EU, so UK nationals still use the same simplified route after 1 January 2021.
Do I actually need one to buy property in Spain?
Yes — for most non-resident buyers, at least one apostilled document will come up. The most common situations are:
- Power of attorney (POA) — if you can't fly to Spain to sign in person, you can sign a POA at a notary at home so your lawyer signs for you. That POA must be apostilled before a Spanish notary will accept it.
- NIE number applications made from abroad through a Spanish consulate, which often require an apostilled criminal-record certificate.
- Mortgage or tax paperwork — Spanish banks may ask for a tax-residence certificate or proof of income from your home country, apostilled.
- Marriage or birth certificates — needed if you're buying jointly, inheriting, or registering a marital-property regime.
If you're flying to Spain, getting your NIE in person, and signing the deed yourself, you may not need any apostille at all. In practice, though, most first-time buyers use a lawyer and a power of attorney — and that alone triggers the requirement.
How to get an apostille in the UK
In the UK, apostilles are issued by the Foreign, Commonwealth & Development Office (FCDO) Legalisation Office. You send the original document (not a photocopy), and it comes back with the apostille attached. The FCDO offers three routes:
| Route | Cost per document | Notes |
|---|---|---|
| Standard postal | £45 | Direct to the FCDO |
| Registered business provider | £40 | Faster, via approved agent |
| e-Apostille | £35 | Digital, only for certain documents |
Fees are set by the FCDO and current as of 2026 (De la Guía Luzón, May 2026). A power of attorney has to be signed and notarised by a UK notary public or solicitor before the FCDO will apostille it — so budget for the notary fee too.
How to get an apostille in Poland
In Poland, most apostilles are issued by the Ministerstwo Spraw Zagranicznych (MSZ) in Warsaw. The fee is 60 zł per document (Linguaforum, verified 22 July 2026), paid by bank transfer before you submit. You can apply in person at ul. Krucza 38/42 in Warsaw, or send the original document by post or courier — useful if you're already in Spain. Processing typically takes 1–3 business days.
Two exceptions: university diplomas go to NAWA, and school certificates go to the regional education authority (kuratorium). For a property purchase, this rarely matters — the documents you'll need (POA, criminal record, civil-status certificates) all go through the MSZ.
The step most buyers forget: sworn translation
An apostille alone is not enough. Spain requires most foreign documents to also be translated into Spanish by a traductor-intérprete jurado — a sworn translator officially appointed by the Spanish Ministry of Foreign Affairs (MAEC). Do it in this order:
- Sign or obtain the original document at home.
- Get it apostilled in your home country.
- Have the apostilled document sworn-translated into Spanish — usually easiest to arrange in Spain, so your lawyer can hand it straight to the notary.
If you translate before apostilling, some Spanish authorities will reject it — and you'll have to start over.
Realistic timeline
If you're organised, the whole apostille + translation process takes about 2–4 weeks. UK e-Apostille turnaround is often a few days; postal is longer. Polish MSZ typically takes 1–3 business days plus post. Add another few days for a sworn translator in Spain. Start as soon as you've reserved the property — long before the completion date at the notary.
How DirecSpain fits in
DirecSpain is a commission-free portal connecting British and Polish buyers directly with agencies holding listings on the Costa Blanca and Costa Cálida. We don't add a buyer's commission on top of your purchase, and the partner agency your lawyer works with can point you to a trusted sworn translator locally — so the apostille step is the last piece to sort out at home, not a headache at the notary.
FAQ
Does an apostille expire?
The apostille itself doesn't expire, but the underlying document might. Spanish authorities usually want a criminal-record certificate or civil-status certificate issued within the last 3–6 months.
Can I apostille a photocopy?
No. Per the Spanish Ministry of Foreign Affairs, only original documents or true copies issued by the same authority are accepted. Apostilled photocopies won't work.
Do I need an apostille if I go to Spain to sign in person?
Often no — if you sign at the Spanish notary yourself and get your NIE in person in Spain, you may avoid the POA route entirely. Ask your lawyer before flying.
Who arranges the sworn translation — me or my lawyer?
Usually your Spanish lawyer arranges it, because they know which MAEC-listed translators the local notary accepts. Just get the apostille first.
Is an "e-Apostille" accepted in Spain?
Yes in principle — Spain accepts digital apostilles from Hague members that issue them. In practice, check with your notary in advance, as some still prefer the paper version.
