, anyone who immigrated to Israel after 1990 and wishes to marry or divorce via the Jewish tradition within the state limits must go through a "Judaism test" at an Orthodox Rabbinical court. In this test, a person would need to prove their claim to be Jewish to an investigator beyond a reasonable doubt. They would need to present original documentation of their matriline up to their great-grandmother (4 generations), or in the case of Ethiopian Jews, 7 generations back. In addition, they should provide government documents with nationality/religion shown as Jewish (e.g., birth/death certificates, marriage documents, etc.).
