Spanish nationality by option
This option is a benefit that our legislation offers to foreigners who meet certain conditions to acquire Spanish nationality. They will have the right to acquire Spanish nationality by this means:
Those persons who are or have been subject to the parental authority of a Spaniard.
Those whose father or mother is Spanish and was born in Spain.
Those persons whose filiation determination (filiation determination means to establish who are the parents of a person) or birth in Spain occurs after the age of eighteen. In this case, the term to opt for the nationality is of two years since the filiation or birth is determined.
Those persons whose adoption by Spaniards takes place after the age of eighteen. In this case the right to opt exists until two years after the adoption is constituted.
Nationality by option is the most common case for foreign parents residing in Spain, who acquire Spanish nationality having minor children at that time. For these minor children a right arises to opt for the Spanish nationality of their parents, but provided that they make use of this right within the term established by our regulations.
