Sefer Yesod
Nachalas Shivah. First Edition. Amsterdam, 1667
Laws of writing deeds, marital and divorce documents by Rabbi Shmuel Halevi Segal, Av Beis Din of Bomberg and its environs.
Nachalas Shivah is the fundamental source for the halachos pertaining to writing kesubos, gittin and shtaros. It was accepted universally by all Poskim throughout the generations, and it is the primary resource used by every scribe charged with writing halachic deeds.
Rabbi Shmuel Halevi Segal (1626-1681), Av Beis Din of Bomberg, was a disciple of the Taz and Rabbi Sheftel Horowitz, whom he quotes extensively in his sefer. In 1648, he fled the Chmielnicki massacres in Poland to Germany where he was appointed Rav of several communities, most notably among them Bomberg.
