Some people can obtain the Spanish nationality because they were:
- Born from a Spanish Parent
- Born in Spain from foreign parents, but one of them was born in Spain also
- Born in Spain from both parents stateless or if neither of the parent's originating countries gives the child their nationality. This situation requires a civil registry process to be followed where Spanish nationality is declared.
- Born in Spain from parents unknown. When a child's first known location is in Spain, then it's presumed to have been born in Spain.
- Adopted by a Spaniard. If someone is adopted after turning 18, then that person may elect Spanish nationality in the 2 years after the adoption.
- Descendants from Sephardic Jews who where thrown out of Spain in 1492.
