Spanish citizenship by possession of status: requirements and how it is established
Article 18 of the Civil Code allows a person to establish Spanish citizenship if they have possessed and used it for ten years, in good faith and on the basis of a title registered with the Civil Registry, even if that title is subsequently annulled.
10 consecutive years
Spanish citizenship must have been possessed and used for ten years.
Registered with the Civil Registry
The situation must be based on a citizenship title registered with the Civil Registry.
Good faith
The person must have used Spanish citizenship in the legitimate belief that they were Spanish.
What is Spanish citizenship by possession of status?
So-called citizenship by possession of status is technically a ground for consolidating Spanish citizenship . Its purpose is to protect someone who has acted as a Spanish citizen for an extended period in good faith and on the basis of a registered title, even if that title is later found to be invalid or is annulled.
It is therefore different from Spanish citizenship by residence , citizenship by option and citizenship by grant .
Requirements for consolidating citizenship by possession of status
These are not alternative requirements. For citizenship to be consolidated, all the elements required under Article 18 and the Civil Registry’s interpretation of this legal concept must be present.
Registered title
The citizenship claimed must be based on a title registered in the Civil Registry.
Ten consecutive years
The person must have held and used Spanish citizenship continuously for ten years.
Good faith
The person must have had a legitimate belief that they were Spanish, without knowing that the title might be invalid.
Actual possession and use
A passive registration is not enough: the person must have acted consistently with their status as a Spanish citizen.
What does it mean to act in good faith and use Spanish citizenship?
The Ministry of Justice explains that good faith exists when the person is unaware of the true situation—in other words, they genuinely believe they are Spanish. In addition, the phrase “possession and use” requires an active approach : the person must have acted as a Spanish citizen in exercising rights and fulfilling duties before the bodies of the Spanish State.
Legitimate belief
The person uses their citizenship believing that the title on which it is based is valid.
Conduct as a Spanish citizen
There must be actual conduct consistent with the status of a Spanish citizen.
Mere appearance is not enough
A single registration or a purely formal status does not replace the legal requirements.
Knowledge of the irregularity
If the person knew that they did not actually hold Spanish citizenship, the required good faith may be lacking.
What must be demonstrated to the Civil Registry?
Official information does not provide a single, definitive list of documents that applies to every case. The application file must allow the registered legal basis, the ten-year period, good faith and the actual use of Spanish nationality to be verified.
Registered legal basis or entry on which Spanish status was based.
Continuity over ten years in possessing and using Spanish nationality.
Evidence of good faith and the legitimate belief that you were Spanish.
Evidence of having acted as a Spanish citizen in relation to rights, duties and dealings with public authorities.
Where do you submit an application based on possession of status?
According to the Ministry of Justice, the application file is processed and decided by the Civil Registry for the interested person’s place of residence . The application form can also be obtained from that Civil Registry.
Gather your civil registration records
Identify the registered legal basis that gave rise to your Spanish status and the related documents.
Prove the ten-year period
Prepare evidence showing continuous possession and use throughout the statutory period.
Show good faith and active use
The application file must show that you genuinely acted as a Spanish citizen, believing legitimately that you were one.
Submit your application to your Civil Registry
The Civil Registry for your place of residence processes and decides the relevant application file.
Possession of status is not a grant of citizenship by residence
This provision must not be confused with the rules on Spanish citizenship by residence or by grant of citizenship by Royal Decree. Article 23 of the Civil Code sets out common requirements for acquisition by option, grant by Royal Decree or residence ; consolidation under Article 18 is a separate provision.
Consolidates a nationality that has been used
Protects a status maintained for ten years in good faith and on the basis of a registered legal title.
Article 18Grant after legal residence
This is based on a citizenship application relying on years of legal residence and other requirements.
