Apostille Documents for Spain: What You Need for Probate and Inheritance
Every foreign document you present to a Spanish notary, court, or tax office must carry a Hague Apostille and a sworn Spanish translation. This applies to birth certificates, marriage certificates, death certificates from the home country, probate grants, and powers of attorney. Missing either the apostille or the translation will stall the process — the notary will simply refuse to proceed.
What the Hague Apostille Is
The Apostille of the Hague Convention (1961) is a standardised international certificate that authenticates the origin of a public document. It doesn't certify the content of the document — only that the signature and seal are genuine and that the issuing authority had the power to issue it.
For UK documents, apostilles are issued by the Foreign, Commonwealth & Development Office (FCDO). For US documents, they come from the Secretary of State of the issuing state (not the federal government). For Irish documents, the Department of Foreign Affairs handles apostilles.
Processing times vary: UK apostilles typically take 4 to 6 weeks by post (or same-day if done in person at the FCDO office in Milton Keynes), US apostilles take 1 to 3 weeks depending on the state, and Irish apostilles usually take 5 to 10 working days.
Which Documents Need Apostilles
For a typical expat estate in Spain, you'll need apostilled originals of:
- Birth certificates of all heirs (to prove relationship to the deceased)
- Marriage certificate (to prove spousal rights)
- Home-country death certificate (if the death was also registered abroad)
- Probate grant or Letters of Administration from the home country (if dual-jurisdiction)
- Power of attorney (poder notarial) if someone is acting on behalf of an heir
Documents already issued by Spanish authorities — the Spanish death certificate, Modelo 790 certificates — don't need apostilles. They're already in the system.
Sworn Translations (Traduccion Jurada)
Every apostilled document must also be accompanied by a sworn Spanish translation, prepared by a certified translator (traductor jurado) officially registered with the Spanish Ministry of Foreign Affairs.
This is not a regular translation. A traduccion jurada carries the translator's official seal and a declaration of accuracy. Only translations done by ministry-registered translators are accepted by Spanish notaries and courts.
You can search for registered translators by language and region on the Ministry of Foreign Affairs database at exteriores.gob.es. Select "Ingles" (English) and "Activo" (Active) to find translators near the notary handling the estate.
Typical costs: EUR 50 to 100 per page, with turnaround times of 3 to 5 working days.

Powers of Attorney for Remote Heirs
If heirs cannot travel to Spain to attend the notary signing in person, they need to grant a power of attorney (poder notarial) to a trusted representative — usually a Spanish lawyer or a family member already in Spain.
For the poder to be valid in Spain, it must be:
- Signed before a notary public in the heir's home country
- Apostilled by the relevant authority
- Translated by a sworn translator into Spanish
- Specific enough to cover the inheritance acts — a general power of attorney may not suffice. The poder should explicitly authorise the representative to accept or reject the inheritance, sign the deed of inheritance, file tax returns, and operate on bank accounts.
Some Spanish notaries will also accept powers of attorney granted at a Spanish consulate abroad, which can be faster since they issue the document in Spanish and no translation is needed.
