Short answer. Ownership is the right to a thing; possession is the fact of holding it. The Civil Code recognises that a person may possess in the concept of owner, or merely as a holder while the ownership belongs to someone else. A tenant possesses a house; the landlord owns it.
What the law says
The possession of things or rights may be had in one of two concepts: either in the concept of owner, or in that of the holder of the thing or right to keep or enjoy it, the ownership pertaining to another person.

Two concepts, two very different positions
Article 525 of the Civil Code draws the line. Possession in the concept of owner means holding the thing as if it were yours, publicly and under a claim of ownership — whether or not that claim turns out to be good. Possession in the concept of holder means keeping or enjoying the thing while acknowledging that the ownership belongs to another. Tenants, depositaries, borrowers, agents, usufructuaries and caretakers are all holders. They may have physical control for years, and they may have real and enforceable rights, but they never possess as owners because they have always recognised somebody else's title.
Why the concept decides who wins
Only possession in the concept of owner can ripen into ownership through acquisitive prescription. Continuous, public, peaceful and adverse possession over the periods the Civil Code fixes can convert a possessor into an owner. A holder can occupy land for fifty years and acquire nothing, because his possession was never adverse — it was permitted. This is why a caretaker's long stay does not defeat the owner, and why an heir who lets a sibling live on family land is not automatically giving it away. The concept in which possession began also governs how it may be changed, and a holder cannot unilaterally convert his own possession into an adverse one just by deciding to.
What possession gives you even without title
Possession is protected as a fact in its own right. A person in actual possession is presumed to hold a just title and cannot be obliged to show it, and possession of movable property acquired in good faith is equivalent to title. No one may be dispossessed by force or intimidation, whatever the strength of the other side's papers — which is why an owner who evicts an occupant himself, instead of going to court, can end up the defendant. Summary actions to recover physical possession are decided on the fact of prior possession alone, leaving the question of ownership to a separate case.
The trap for buyers and for families
Registered land is where this hurts most. A certificate of title proves ownership, but it does not tell you who is on the land, and buyers who inspect only the registry and never the property inherit a possessor along with the lot. Conversely, a family member who has occupied inherited land for decades often assumes that occupation alone has made him the owner; usually it has not, because his possession began as a co-heir's, not adversely. Whether your possession was ever in the concept of owner is a factual question decided on documents, tax declarations and conduct. This is general legal information, not advice; you can book a consultation to have a property situation reviewed.
