The courts have denied Spanish nationality to a Colombian woman who passed the Cervantes Institute exam but failed to prove her Sephardic origins.

The Audiencia Provincial de Madrid in Spain has confirmed the denial of Spanish nationality to a Colombian citizen named Estibaliz. Although she successfully passed the Instituto Cervantes exam, her request for nationality by letter of nature was rejected because she failed to adequately accredit her Sephardic origin.

The case highlights the strict evidentiary requirements mandated by Spanish authorities for nationality applications tied to specific ancestral provisions, demonstrating that passing linguistic and cultural evaluations alone is insufficient without documented proof of heritage.
