Apostille for Your NIE Power of Attorney

Key facts
  • An apostille certifies that a public document is genuine for use in another country.
  • It works between countries in the Hague Convention (1961).
  • Your NIE power of attorney must be apostilled before it is valid in Spain.
  • If your country is not in the Convention, you legalise via the Spanish consulate instead.

An apostille is what makes your notarised power of attorney legally usable in Spain. Without it, Spanish authorities will not accept a foreign document.

What the apostille does

It is a standardised certificate attached to your notarised POA confirming the notary’s signature and authority. Under the Hague Convention, an apostilled document is accepted in all member states without further legalisation.

Who issues it

The designated authority in the country where the document was notarised — for example a foreign ministry, court, or other competent body, depending on your country. You obtain it after the POA is signed before the notary and before the sworn translation.

If your country isn’t in the Hague Convention

You use consular legalisation instead: the document is legalised through the Spanish consulate (and your own authorities) so it has the same effect. The order of steps is summarised in the remote NIE process.
