Usufruct

Usufruct is the right to use and benefit from a property, while the ownership of which belongs to another person. The person who enjoys the usufruct is called the usufructuary. The usufructuary shall maintain the property as a responsible owner and shall not cause damage to or diminution of the property, except where the property is subject to natural depletion over time. In modern civil law, the usufruct is divided into perfect usufruct and imperfect usufruct or quasi-usufruct, depending on whether the property is subject to depletion. For perfect usufruct, the property is used without changing its nature. In the latter, the property cannot be used without being consumed, such as money, food, etc., and the usufructuary shall deliver to the owner at the end of the usufruct the same value or the same quantity and quality as at the beginning of the usufruct.

Usufruct is your stewardship.

A person is said to be a usufructuary or to enjoy a usufruct in property in which he has an interest of a special kind for life or some lesser period. The rules of usufruct require that the property be used in such a manner that its corpus is not impaired. The occupant has no right of appropriating immovable property of the enemy state as booty. He has a duty of managing such property and is entitled to the profits arising there from. He cannot sell or alienate such property since this would be exercising sovereignty over the occupied territory. He may lease or utilize lands or buildings for the period of occupation, i.e., he may lease the operation of public railroads, agricultural lands and forests and other public property and receive the profit from their operation. - Law of Belligerent Occupation
