US "long form" birth certificate for procedures in Spain

Why Spain requires the "long form" version of a US birth certificate, how it's apostilled at state level, and when you need it translated.

By Eva Moreno Ortiz ·

When a US citizen needs to submit their birth certificate to a Spanish authority — to get married, register a child, or record a birth with the Civil Registry — the document is frequently rejected for one specific reason: it's not the "long form" version. This guide explains the difference and how to get the right version, apostilled and ready for translation.

Long form vs. short form (or "abstract")

In the United States, many states issue two versions of the birth certificate:

  • Long form (also called a full certified copy): reproduces all the original information, including parents' full names, detailed place of birth, and signatures.
  • Short form / abstract: a summary with the basic data, enough for internal US procedures but not accepted in Spain for Civil Registry entries, since it doesn't prove parentage in the same level of detail.

"Informational" copies marked "Not valid for legal purposes" don't work either, nor do photocopies of the certificate — you need an original certified copy.

The apostille: a state matter, not a federal one

Unlike an FBI criminal record certificate, which is apostilled federally, a birth certificate is apostilled by the Secretary of State of the state that issued it — the same state where the person was born, not where they currently live. If you were born in Texas but live in Florida, the apostille is processed in Texas. The usual timeframe is 5 to 20 business days, not counting mailing time.

When you need it translated in Spain

  • Getting married in Spain — the Civil Registry requires the apostilled and translated birth certificate of the US party. See the guide on getting married in Spain as a US citizen.
  • Registering a child born in the US with Spain's Civil Registry, when one parent is Spanish.
  • Residence visa applications (non-lucrative, digital nomad) when the consulate requests it as part of the file.
  • Dual nationality or family reunification procedures.

Common mistakes

  1. Requesting the "short form" thinking it's enough. Spain's Civil Registry rejects it.
  2. Apostilling in the wrong state. The apostille is issued by the Secretary of State of the state of birth, not of current residence.
  3. Submitting a photocopy instead of the original certified copy — Textualia needs the original or a certified copy to produce a valid sworn translation.
  4. Not checking the required recency. Some Spanish bodies require the certificate to have been issued recently (usually under 6 months), even if the birth itself was long ago — request an up-to-date certified copy rather than reusing an old one.
