Bava Batra 13: A Bathhouse, an Olive Press, and Sacred Scrolls

Cases of dividing property in inequitable ways - for example, when a father leaves a bath house or an olive press to his sons, one of whom is wealthy and one of whom is poor. How can they divide it, and what can't they ask of each other? Plus, the question of whether one can be forced to an agreement one doesn't want. Also, scrolls - can they be divided? How are they to be joined? Can Torah, Neviim (Prophets), and Ketuvim (Writings) be written together? Separate? What about the 5 Books of the Torah? How should the lines of the books be spaced?
