Other forms: curtilages
Curtilage is a fancy legal term for the enclosed land that surrounds a building and belongs with it as part of the same property.
The term comes from the Old French word cortil, meaning a "little court, walled garden, or yard." It's an important legal distinction for many reasons: In some American states, evidence improperly gathered from the curtilage of a property is considered as inadmissible as that gathered from inside a building on the property. In other cases, a property owner may legally defend himself against home invasion within the curtilage of his property, not just within the building itself.
