What this document is
“Solicitud de cambio de nombre y apellidos por causa justa (menores de edad)” is a one-page template published by Comunidad de Madrid on its “Cambio de nombre y apellidos” page. With it the parents, as legal representatives, ask the Civil Registry (Registro Civil) to change a child’s given name or surnames for a just cause (causa justa).
It is a separate template from the “por uso” application: there are no points about the registered and the habitually used name, but two free sections — “EXPONEN” (facts and reason) and “SOLICITAN” (the name or surnames requested).
The heading still reads “Al Sr. Juez - Encargado del Registro Civil”, wording from the former law; Comunidad de Madrid publishes the form this way and we do not change it.
Who files and where
- both parents as the minor’s legal representatives — the form has the lines “D.” and “y Dª.” and the signature “Firma solicitante/s”;
- the child is a Spanish national: the form reads “de nacionalidad española”;
- it is filed with the Civil Registry where the family lives, named in the heading and in the line “Ante el Registro Civil de”; check how to file (appointment, post) on the Comunidad de Madrid page or with your Civil Registry.
What the form asks
- the Civil Registry (town) you file with;
- each parent’s given name, surnames and DNI/NIE;
- the family address: town, street, number, floor and door, postcode; phone and e-mail;
- the child’s given name and surnames, place and date of birth;
- “EXPONEN” — the facts and the just cause; “SOLICITAN” — the new name or surnames;
- consent to SMS or e-mail notices, place and date of signing.
What to bring
- the child’s full birth certificate (certificación literal de la inscripción de nacimiento);
- documents supporting the reason for the change;
- the DNI or another ID of both parents. Check the exact list for your case with the Civil Registry.
How to fill it in with FoxDocs
- Tell the chat, in any language, about yourself, the other parent, the child and the reason for the change.
- The assistant writes the data in capitals, drafts “EXPONEN” and “SOLICITAN” in Spanish from your words and adds the date with the month in Spanish.
- Download the PDF, check the text, print it and sign it together with the other parent.
