A get belongs to the second category.
A get is the Jewish document of divorce
Britannica defines a get as the Jewish divorce document written in Aramaic according to a prescribed formula.
This is the core legal instrument that dissolves a marriage under halakhic standards.
It matters especially in traditional Jewish law
Britannica notes that Orthodox and Conservative Jews recognize the get as the valid instrument for severing a marriage bond, while Reform Judaism generally does not require it in the same way.
That difference is important because the get sits at the intersection of religious authority, civil law, and gendered power.
The process is legal and ritual
Britannica describes the formal delivery of the document in the presence of witnesses and a rabbinic court.
This means the get is not only paperwork. It is a structured religious procedure.
Why it still matters
The get still matters because questions of marriage and divorce remain one of the clearest places where Jewish law continues to operate as a legal system, not only as culture or symbolism.
The shortest accurate answer
A get is the Jewish document of divorce used to dissolve a marriage under halakhic law, especially in Orthodox and Conservative practice.
