Paternity recognition at the Registro Civil

What you need to have to hand

1. DNI/NIE/passport of the father recognising, valid.
2. Certificado literal de nacimiento of the child if already registered without paternal filiation (request it at the Registro where the birth was registered).
3. DNI/NIE of the mother and her consent if the child is a minor not emancipated.
4. Consent of the child if they are 12 or older (and of an adult child, always).
5. Libro de Familia if it exists, for annotation.
6. If the mother is married or there was a marriage close to the birth, prepare certificado de matrimonio or proof of civil status (because of the presumption of paternity).

Documentation

• Identification of the father: DNI/NIE/passport.
• Literal de nacimiento del hijo (only if the child was already registered without a father). If you don't have it, the Registro can request it ex officio if it's the same RC; if it's another RC, bring it to save time.
• Consents: mother (if minor not emancipated) and the child's consent if ≥12 or if an adult.
• Libro de Familia for annotation (if you have one).
• Previous resolutions (resolución or sentencia de filiación, impugnación) if any.

Step by step

1. Find the competent Registro: normally the Registro Civil del nacimiento. If it's inconvenient you can go to another RC and they remitirán the act; that takes longer.
2. Book an appointment at justicia.gob.es → Registro Civil or at the RC's own page. In big cities slots go fast; try first thing in the morning.
3. Attend: on the day the father and, where applicable, the mother and/or the child (≥12) must attend. There you sign the acta de reconocimiento before the Encargado.
4. If you recognised before a notary/consulate: deliver the testimonio or authorised copy to the RC of the birth so they can enter it. Without that entry, civil effects are not completed.
5. Annotation: the RC enters the filiation in the birth entry. If done at the birth RC, it can be the same day; if it must be remitted, expect 1–4 weeks.
6. Collect certificates: updated literal de nacimiento and Libro de Familia with the new filiation. You'll need these for surnames, passports, etc.

Time-saving tips

• Bring photocopies of DNI/NIE and signed consents if someone cannot attend.
• If the birth is recent, try to do it together with the registration: you may finish everything at once.
• In overloaded RCs (Madrid, Barcelona), booking first thing Monday can work better. Keep trying on different days.
• If you use a notary for speed, ask first about the arancel and the time to issue the testimonio. Then deliver it to the RC as soon as possible.

Typical mistakes that will mess up the process

1. Turning up without the mother when the child is not emancipated: without her consent there is no recognition.
2. Forgetting the child's consent if they are 12 or older: they'll send you home.
3. Ignoring the presumption of paternity: if the mother was married at the time of birth, your declaration alone is not enough. You may need to impugnar.
4. Going to the wrong RC expecting it to be immediate: if it's not the birth RC there will be remisión and delays.
5. Relying only on online options: booking can be online, but the signature is in person. Don't turn up without an appointment in big cities; you'll waste the morning.
