A more thorough explanation:

Definition: Jus oneris ferendi is a Latin term used in Roman law to refer to an urban praedial servitude that grants the right for one's own house to be supported by a neighbor's. This servitude is exceptional in that it requires a positive duty of the servient owner.

Example: An example of jus oneris ferendi would be if a homeowner's house was built on a slope and required additional support to prevent it from collapsing. The homeowner could obtain the right to have their neighbor's property support their house through the use of jus oneris ferendi.

This example illustrates how jus oneris ferendi can be used to grant a homeowner the right to have their neighbor's property support their own property. This servitude is unique in that it requires the servient owner to take on a positive duty to support their neighbor's property.
