Why it matters

Spanish authorities cannot verify a document issued in Ohio or by the FBI. They don’t know the seals, the signatures, or the databases. The apostille solves that: a single standardized certificate, created by the 1961 Hague Convention, that tells any member country “this document is genuine — you may rely on it.”

For Spain’s Digital Nomad Visa, this is not a technicality. An unapostilled FBI background check is, legally speaking, just a printout. The UGE can and does refuse documents that arrive without one. In my files, the apostille chain is one of the two most common places where do-it-yourself applications lose months — the other being the Certificate of Coverage.

When you need it

You may need an apostille for:

  • FBI background check — federal apostille, every adult applicant
  • ACRO certificate — if you lived in the UK recently (apostilled in the UK)
  • Marriage certificate — state apostille, for spouses applying together
  • Birth certificates — state apostille, for children in the application
  • University diploma — if you prove qualifications by degree rather than experience
  • Certificate of Incorporation or Good Standing — for business owners proving company age
  • Powers of attorney and notarized declarations, when your case uses them

How it works

The sequence matters more than people expect. The visual version:

  • 1 · Get the right original. The official document, issued recently enough to still be fresh at filing.
  • 2 · Notarize first — only if required. Some private documents must be notarized before any authority will apostille them.
  • 3 · Send it to the competent authority. Federal documents → U.S. Department of State. State documents → that state’s Secretary of State.
  • 4 · Receive the apostille. A numbered certificate physically attached to your document.
  • 5 · Sworn translation. Document and apostille together, translated by a sworn translator.
  • 6 · Into the file. It’s now a document Spain will accept — and the clock on its freshness is running.

Timing is the strategic part. A state apostille often takes days; the federal apostille for FBI results takes weeks by mail — which is why it starts early in my document sequence, timed so nothing expires before we file.

Common mistakes

  • Sending the FBI check to a state office. States cannot apostille federal documents. It comes back unprocessed, weeks later.
  • Apostilling a photocopy. Authorities need originals or certified copies. Home printouts bounce.
  • Letting the document expire under the apostille. The apostille is permanent; the criminal record certificate underneath goes stale in about three months. Order dates have to be planned backward from filing week.
  • Confusing notarization with an apostille. A notary stamp alone means nothing to Spain.
  • Translating before apostilling. The sworn translation must cover the apostille too — do it last, or pay twice.

Frequently asked questions

Only countries that joined the Hague Apostille Convention — currently more than 120, including the United States, the United Kingdom, and Spain. Documents from a non-member country need the older, slower consular legalization process instead.

Generally no. Apostilles attach to original public documents or to properly certified copies. A home-printed photocopy of your FBI results or birth certificate will be rejected — the authority needs the version it can verify.

Increasingly, yes — Spain participates in the electronic apostille program (e-APP) and the UGE files everything digitally anyway. But not every U.S. authority issues them, so most U.S. files still travel on paper apostilles that we scan for filing.

The apostille itself never expires. What expires is the document underneath: Spain treats criminal record certificates and civil certificates as fresh for roughly three months. An apostilled FBI check from last year fails on the document’s age, not the apostille’s.

Yes. The apostille certifies authenticity; it doesn’t translate anything. Every apostilled document — including the apostille page itself — needs a sworn translation into Spanish before filing.

No. A notary verifies a signature in front of them. An apostille is issued by a government authority and certifies the document itself for international use. Some documents need notarization first and the apostille on top — but one never replaces the other.

It depends on the document. Federal documents like the FBI background check are apostilled by the U.S. Department of State in Washington. State documents — birth certificates, marriage certificates, notarized papers — are apostilled by the Secretary of State of the issuing state.
