The Law establishes the right to Spanish nationality of Sephardi Jews with a connection to Spain who apply within three years from 1 October 2015. The law defines Sephardic as Jews who lived in the Iberian Peninsula until their expulsion in the late fifteenth century, and their descendants. The law provides for the deadline to be extended by one year, to 1 October 2019; it was extended in March 2018. It was modified in 2015 to remove a provision that required persons acquiring Spanish nationality by law 12/2015 must renounce any other nationality held. Most applicants must pass tests of knowledge of the Spanish language and Spanish culture, but those who are under 18, or handicapped, are exempted. A Resolution in May 2017 also exempted those aged over 70.
