In law, possession is the control a person intentionally exercises toward a thing. Like ownership, the possession of anything is commonly regulated by country under property law. In all cases, to possess something, a person must have an intention to possess it. A person may be in possession of some property (although possession does not always imply ownership). Intention to possess An intention to possess (sometimes called animus possidendi) is the other component of possession. All that is required is an intention to possess something for the time being. In common law countries, the intention to possess a thing is a fact. Normally, it is proved by the acts of control and surrounding circumstances. It is possible to intend to possess something without knowing that it exists.

In such circumstances, some people make it clear that they do not want possession of the things brought there by the public. For example, it is not uncommon to see a sign above the coat rack in a restaurant which disclaims responsibility for items left there.

For example, an owner of residential property may assign the right of possession to a property manager under a property management contract who may then assign the right of possession to a tenant under a rental agreement. There is a rebuttable presumption that the
