Deuteronomy 24:3

And write her a bill of divorcement - These bills, though varying in expression, are the same in substance among the Jews in all places. The following, collected from Maimonides and others, is a general form, and contains all the particulars of such instruments. The reader who is curious may find a full account of divorces in the Biblioth. Rab. of Bartolocci, and the following form in that work, vol. iv., p. 550.

“In - day of the week, or day - of the month A., in - year from the creation of the world, or from the supputation (of Alexander) after the account that we are accustomed to count by, here, in the place B., I, C., the son of D., of the place B., (or if there be any other name which I have, or my father hath had, or which my place or my father’s place hath had), have voluntarily, and with the willingness of my soul, without constraint, dismissed, and left, and put away thee, even thee, E., the daughter of F., of the city G., (or if thou have any other name or surname, thou or thy father, or thy place or thy father’s place), who hast been my wife heretofore; but now I dismiss thee, and leave thee, and put thee away, that thou mayest be free, and have power over thy own life, to go away to be married to any man whom thou wilt; and that no man be refused of thine hand, for my name, from this day and for ever. And thus thou art lawful for any man; and this is unto thee, from me, a writing of divorcement, and book (instrument) of dismission, and an epistle of putting away; according to the Law of Moses and Israel.
A., son of B., witness.
C., son of D., witness.”
