What were the Jews in Spain required to do in 1492?

Answer 1

The Spanish Inquisition was intended to identify, and remove, those "conversos" who were fake Catholics.

After the Catholics defeated the last Muslim strong-hold (Grenada), the Church in Spain instituted the Spanish Inquisition to root-out all persons merely pretending to be Catholics for whatever personal, political power or financial reason that was the root-cause of their pretending, dishonestly, to be Catholic.

In fact, the Jews in Spain appealed to the pope at that time to intervene. Pope did -- told the Church in Spain to cease and desist. Church in Spain refused to obey which is similar to what still occurs today.

WHAT SPECIFICALLY DID THE JEWS HAVE TO DO WITH THE SPANISH INQUISITION?

Nothing. They were mistreated victims by the majority of Spaniards (Catholics) who pretty much wanted everyone -- who was not a Catholic -- out of Spain. After hundreds of years of Muslim rule, and finally defeating the Muslims, the Spanish Catholics trusted no one -- including Jews.

In fact, after the final liberation of Spain, Protestant Christians also tried to come to Spain and convert Catholics. They too were not permitted in Spain. This was the time of the Reformation elsewhere in Europe.

Spanish Inquisition was wrong. In hindsight, it was also understandable.

Answer 2

The Spanish Inquisition was incorporated under Christian Church law and was therefore did not apply to Jews.
However, after the defeat of the Muslim rulers of Spain, many Jews were forced to convert to Christianity or face deportation. Once they converted, no matter how unwillingly, they became irrevocably subject to the Inquisition. The original purpose of the Spanish Inquisition was to identify those conversos who continued secretly to follow their ancestral religions of Judaism or Islam.
