What can partners in a shared courtyard compel each other to build?
Partners can compel each other to contribute to building a gate-keeper's room, a door, and a latch for the courtyard — these are standard shared-courtyard necessities.
Question 2
A partner brings a mill into the shared courtyard without asking. The other partner says nothing for a year. Can he now object?
Silence in the face of a partner's new use is treated as consent — the partner who failed to object in a timely manner loses the right to demand removal.
Question 3
Can a partner open a new window from his house overlooking the shared courtyard?
A partner may open a window overlooking the shared courtyard — it is his right as part-owner of the space. However, the other partner can demand he not open one facing a private area.
Question 4
Can a person open a new entrance from his house into a cul-de-sac lane?
The residents of a cul-de-sac lane may object to a new entrance being opened — it increases foot traffic in their private lane.
Question 5
If someone had an entrance to a cul-de-sac lane that was closed, can he reopen it?
A previously closed entrance may be reopened at any time — the person retains the right to use it since the original entrance was established.
