Ownership is the state or fact of legal possession and control over property, which may be any asset, tangible or intangible. Ownership can involve multiple rights, collectively referred to as title, which may 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, misplacing it, or having it stripped from one's ownership through legal means such as eviction, foreclosure, seizure, or taking. Ownership implies that the owner of a property also owns any economic benefits or deficits associated with the property.

History Over the millennia and across cultures, notions regarding what constitutes "property" and how it is treated 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.Theory of Moral Sentiments. Ed. A.L. Macfie and D.D. Raphael.

Types of owners

In person Individuals may own property directly. In some societies only adult men may own property; in other societies (such as the Haudenosaunee), property is matrilinear and passed on from mother to the offspring. In most societies both men and women can own property with no restrictions and limitations at all.

Structured ownership entities Throughout history, nations (or governments) and religious organizations have owned property. These entities exist primarily for purposes other than to own or operate property; hence, they may have no clear rules regarding the disposition of their property.

To own and operate property, structures (often known today as legal entities) have been created in many societies throughout history. The differences in how they deal with members' rights is a key factor in determining their type. Each type has advantages and disadvantages derived from their means of recognizing or disregarding (rewarding or not) contributions of financial capital or personal effort.

Cooperatives, corporations, trusts, partnerships, and condominium associations are only some of the many varied types of structured ownership; each type has many subtypes. Legal advantages or restrictions on various types of structured ownership have existed in many societies past and present. To govern how assets are to be used, shared, or treated, rules and regulations may be legally imposed or internally adopted or decreed.

Liability for the group or for others in the group Ownership by definition does not necessarily imply a responsibility to others for actions regarding the property. A "legal shield" is said to exist if the entity's legal liabilities do not get redistributed among the entity's owners or members. An application of this, to limit ownership risks, is to form a new entity (such as a shell company) to purchase, own and operate each property. Since the entity is separate and distinct from others, if a problem occurs which leads to a massive liability, the individual is protected from losing more than the value of that one property. Many other properties are protected, when owned by other distinct entities.

In the loosest sense of group ownership, a lack of legal framework, rules and regulations may mean that group ownership of property places each member in a position of responsibility (liability) for the actions of every other member. A structured group duly constituted as an entity under law may still not protect members from being personally liable for each other's actions. Court decisions against the entity itself may give rise to unlimited personal liability for each and every member. An example of this situation is a professional partnership (e.g. law practice) in some jurisdictions. Thus, being a partner or owner in a group may give little advantage in terms of share ownership while producing a lot of risk to the partner, owner or participant.

Sharing gains At the end of each fiscal year, accounting rules determine a surplus or profit, which may be retained inside the entity or distributed among owners according to the initial setup intent when the entity was created. For public corporations, common shareholders have no right to receive any of the profit.

Entities with a member focus will give financial surplus back to members according to the volume of financial activity that the participating member generated for the entity. Examples of this are producer cooperatives, buyer cooperatives and participating whole life policyholders in both mutual and share-capital insurance companies.

Entities with shared voting rights that depend on financial capital distribute surplus among shareholders without regard to any other contribution to the entity. Depending on internal rules and regulations, certain classes of shares have the right to receive increases in financial "dividends" while other classes do not. After many years the increase over time is substantial if the business is profitable. Examples of this are common shares and preferred shares in private or publicly listed share capital corporations.

Entities with a focus on providing service in perpetuam do not distribute financial surplus; they must retain it. It will then serve as a cushion against losses or as a means to finance growth activities. Examples of this are not-for-profit entities: they are allowed to make profits, but are not permitted to give any of it back to members except by way of discounts in the future on new transactions.

Depending on the charter at the foundation of the entity, and depending on the legal framework under which the entity was created, the form of ownership is determined once and for all time. To change it requires significant work in terms of communicating with stakeholders (member-owners, governments, etc.) and acquiring their approval. Whatever structural constraints or disadvantages exist at the creation thus remain an integral part of the entity. Common in, for instance, New York City, Hamburg, and Berlin is a form of real estate ownership known as a cooperative (also co-operative or co-op, in German Wohnungsgenossenschaft – apartment co-operative, also "Wohnbaugenossenschaft" or simply "Baugenossenschaft") which relies heavily on internal rules of operation instead of the legal framework governing condominium associations. These "co-ops", owning the building for the mutual benefit of its members, can ultimately perform most of the functions of a legally constituted condominium, i.e. restricting use appropriately and containing financial liabilities to within tolerable levels. To change their structure now that they are up and operating would require significant effort to achieve acceptance among members and various levels of government.

Sharing use The owning entity makes rules governing use of property; each property may comprise areas that are made available to any and every member of the group to use. When the group is the entire nation, the same principle is in effect whether the property is small (e.g. picnic rest stops along highways) or large (such as national parks, highways, ports, and publicly owned buildings). Smaller examples of shared use include common areas such as lobbies, entrance hallways and passages to adjacent buildings.

One disadvantage of communal ownership, known as the Tragedy of the Commons, occurs where unlimited unrestricted and unregulated access to a resource (e.g. pasture land) destroys the resource because of over-exploitation. The benefits of exploitation accrue to individuals immediately, while the costs of policing or enforcing appropriate use, and the losses dues to over exploitation, are distributed among many, and are only visible to these gradually.

In a communist nation, the means of production of goods would be owned communally by all people of that nation; the original thinkers did not specify rules and regulations.

Ownership models State ownership: ownership of an industry, asset, or enterprise by the state or a public body representing a community as opposed to an individual or private party. Public ownership: ownership and operation of an enterprise by a central government; also an ambiguous term that could refer to either social, partial state, or full state ownership. Private ownership: exclusive ownership of property by non-governmental legal entities. Fractional ownership: ownership held in percentage shares of an expensive asset, sold to individual owners, who are charged fees for the asset's management and variable use. Collective ownership: either joint ownership of an economic entity (e.g., a cooperative) or public ownership. Cooperative ownership: ownership by the people who together operate and trade with an enterprise. Common ownership non-exclusive ownership of property by everyone involuntarily. Property is also distinguished by whether it is movable (personal property)"Personal property". Sir Robert Harry Inglis Palgrave. Dictionary of political economy, Volume 3. 1908. p. 96 or immovable (immovable property and real property). Property can also be distinguished by whether or not it is owned with exclusive rights, such rights grant owners a monopoly to refuse ownership to non-owners. Concerning ownership of means of production and delineating which groups receive the direct profits, capitalism's private ownership is distinguished from socialism's social ownership. Ownership of resources can be distinguished as either as individual or communal, analogous to private or public in delineating who has rights of use.

Types of property

Personal property

Personal property is a type of property. In the common law systems personal property may also be called chattels. It is distinguished from real property, or real estate. In the civil law systems personal property is often called movable property or movables – any property that can be moved from one location or another. This term is used to distinguish property that different from immovable property or immovables, such as land and buildings. This also means the direct owner of the item(s) is in full control of them/it until either stolen, confiscated by law enforcement, or destroyed.

Personal property may be classified in a variety of ways, such as goods, money, negotiable instruments, securities, and intangible assets including choses in action.

Land ownership

Real estate or immovable property is a legal term (in some jurisdictions) that encompasses land along with anything permanently affixed to the land, such as buildings. Real estate (immovable property) is often considered synonymous with real property. However, for technical purposes, some people prefer to distinguish real estate, referring to the land and fixtures themselves, from real property, referring to ownership rights over real estate. The terms real estate and real property are used primarily in common law, while civil law jurisdictions refer instead to immovable property.
