Ownership interest

Ownership of property may be private, collective, or common, and the property may be of objects, land or real estate, or intellectual property. Determining ownership in law involves determining who has certain rights and duties over the property. These rights and duties, sometimes called a "bundle of rights", can be separated and held by different parties.

The process and mechanics of ownership are fairly complex: one can gain, transfer, and lose ownership of property in a number of ways. To acquire property one can purchase it with money, trade it for other property, win it in a bet, receive it as a gift, inherit it, find it, receive it as damages, earn it by doing work or performing services, make it, or homestead it. One can transfer or lose ownership of property by selling it for money, exchanging it for other property, giving it as a gift, it, or having it stripped from one's ownership through legal means such as eviction, foreclosure, seizure, or taking. Ownership is self-propagating in that the owner of any property will also own the economic benefits of that property.

Over the millennia, and across cultures what can be property and how it is regarded culturally have varied widely. Ownership is the basis for many other concepts that form the foundations of ancient and modern societies such as money, trade, debt, bankruptcy, the criminality of theft, and private vs. public property. Ownership is the key building block in the development of the capitalist socio-economic system.Adam Smith stated that one of the sacred laws of justice was to guard a person's property and possessions.
