1,742. Inner and Outer Courtyards

Hilchos Geirushin 5:5

If a man throws a get into a fire on his wife’s property and it is destroyed, or into water on her property and it is erased or lost, the get is invalid. If it lands on her property and only subsequently is destroyed, then divorce is effected.

Hilchos Geirushin 5:6

If a man throws a get on top of a reed or a spear planted on his wife’s property, divorce is not effected until it comes to rest in a secure location under her protection. Let’s say that there are two courtyards, the inner one belonging to the woman, the outer one belonging to her husband, and the walls of the outer taller than those of the inner. If the man tosses the get into the airspace of the outer courtyard, divorce is effected because the inner courtyard is protected by the walls of the outer courtyard. This is not the case with vessels.
