Legal Definitions - inaedificatio

Definition: Inaedificatio (in-ee-di-fi-kay-shee-oh) is a term used in Roman law that refers to the act of building on someone else's land with one's own materials or on one's own land with someone else's materials. This act is considered a form of accessio, and regardless of the source of the materials, the building becomes the property of the landowner.

Example: If John builds a shed on Mary's land using his own materials, the shed becomes Mary's property. Similarly, if John uses Mary's materials to build a shed on his own land, the shed becomes John's property.

Explanation: In both examples, the act of building on someone else's land or using someone else's materials to build on one's own land is considered inaedificatio. The shed that is built becomes the property of the landowner, regardless of who provided the materials. This is because the act of building is seen as an addition to the landowner's property, which is a form of accessio.
