Fortunately, you are eligible for Spanish nationality if you reside in Spain legally for two years. The Spanish Civil Code, in its article 22, stipulates that members of the ´sefardi´ community can obtain nationality in that period.
With regards to who this is obtained, any lawyer can set the process in motion once you decide you wish to reside in spain permanently, or at least during the period of two years required by the law. The procedure involves a lot of paperwork and patience, but it is not too complicated.
