Ownership; Mode vs. Title

[1] Ownership is acquired by occupation and intellectual creation.
[2] Ownership and other real rights over property are acquired and transmitted by law, by donation, by estate and intestate succession, and in consequence of certain contracts, by tradition.
[3] They may also be acquired by means of prescription. (Art. 712 of the Civil Code)
[4] Mode and title are different.
[5] Mode is the process of acquiring or transferring ownership. When there is an effective mode of acquisition, ownership is acquired.
[6] Title is that which gives a juridical justification for a mode, that is, it provides the cause for the acquisition of ownership.
