Corpus Possession means that there exists such physical contact of the thing by the possessor as to give rise to the reasonable assumption that other person will not interfere with it. Existence of corpus broadly depends on (1) upon the nature of the thing itself, and the probability that others will refrain from interfering with the enjoyment of it; (2) possession of real property, i.e., when a man sets foot over the threshold of a house, or crosses the boundary line of his estate, provided that there exist no factors negativing his control, for example the continuance in occupation of one who denies his right; and (3) acquisition of physical control over the objects it encloses. Corpus, therefore, depends more upon the general expectations that others will not interfere with an individual control over a thing, then upon the physical capacity of an individual to exclude others.
The animus possidendi is the conscious intention of an individual to exclude others from the control of an object.
There is also a concept of “constructive possession” which is depicted by a symbolic act. It has been narrated with an illustration that delivery of keys of a building may give right to constructive possession of all the contents to the transferee of the key.
A person other than the owner, if continued to have possession of immoveable property for a period as prescribed in a Statute providing limitation, openly, without any interruption and interference from the owner, though he has knowledge of such possession, would crystallize in ownership after the expiry of the prescribed period of limitation, if the real owner has not taken any action for reentry and he shall be denuded of his title to the property in law. “Permissible Possession” shall not mature a title since it cannot be treated to be an “adverse possession”. Such possession for however length of time be continued, shall not either be converted into adverse possession or a title. It is only the hostile possession which is one of the condition for adverse possession. Bhikhari v. D.D.C., 2018 (141) RD 130.
