Does not this mean that there is no need for a partition at all? — No; it means that there is no need for a wall of four cubits, but a partition of ten handbreadths is required. It has been stated: If two courtyards adjoin and one is higher than the other, R. Huna says that the owner of the lower one has to build [the party wall] up from his level, and the owner of the higher one starts building from his level.<span class="x" onmousemove="('comment',' And he has not to contribute to the cost of the wall until it reaches the level of his courtyard.
