Late birth registration of an adult — Civil Registry, Madrid

“Solicitud de inscripción de nacimiento fuera de plazo de mayores de edad” is a one-page application form published by Comunidad de Madrid. With it an adult asks the Civil Registry (Registro Civil) to open a file (expediente) with the participation of the public prosecutor (Ministerio Fiscal) and to authorise the registration of their birth after the legal deadline.

Under Law 20/2011 on the Civil Registry a birth must be declared within ten days (art. 47.1), and a hospital reports it within 72 hours (art. 46). Once the deadline has passed, the birth can only be registered by a decision issued in a registry file (art. 47.3).

The heading still reads “Al Sr. Juez - Encargado del Registro Civil”, wording from the previous law; the form is published that way and we do not change it.

• the adult whose birth is not recorded in the Spanish Civil Registry (there is a separate form for minors);
• it is filed with the Civil Registry named in the heading; check with it in advance which registry is competent in your case and whether you need an appointment (cita previa);
• it is printed and signed by hand.

• the Civil Registry you file with;
• your name and surnames, document number, place and date of birth, address and phone;
• for your father and mother: name and surnames, their parents’ names, place and date of birth, marital status now and on the date of your birth, ID document, nationality, address;
• whether your parents married each other (SI / NO — the wrong word is crossed out), and the place and date;
• place and date of signing.

• your identity document;
• documents proving the facts stated in the application — the form itself says so (birth, identity of the parents, their marriage if any);
• check with the Civil Registry the exact list and format (translation, legalisation of foreign documents) for your case. The form’s page does not state a fee — ask there as well.

1. Tell the chat, in any language, about yourself, your parents and where you live.
2. The assistant writes the data in capitals, your parents’ marital status as a Spanish word, crosses out the wrong SI / NO and adds the date with the month in Spanish.
3. Download the PDF, check it, print and sign it.
