By Usucapio (from the Latin: "to acquire for use") is meant "the right of possession that an individual acquires over a movable or immovable property, due to having used it for a given period of time, in a continuous manner, as if you were the real owner of that asset. "
For this right to be applied, it will be necessary to have recourse to justice to invoke the possession of the property (extrajudicially, or judicially), being necessary that certain requirements are guaranteed:
By good faith it is understood: when the legitimate owner does not oppose the occupier, by bad faith: it is understood the opposite, that is, when the legitimate owner tries to recover the occupied property, being confronted with opposition by the occupier.
In case of bad faith, the legitimate owner can prove it by being accompanied by witnesses, or the police authority, during the attempt to recover the good. You can also file an eviction in court, asking the occupant to leave.
There are exceptions to the use of adverse possession such as: non-apparent building easements or rights of use and housing. Building easement is constituted when the immovable property is used by several people for a certain period of time (eg, a path that crosses land, a shared space in a condominium, etc.).
Once granted in court, this right has retroactive application to the date of the beginning of the investiture.
Below are some of the articles of the Portuguese Civil Code that govern the application of adverse possession to real estate:
Possession of the right to property or other real rights of enjoyment, maintained for a certain period of time, allows the owner, unless otherwise provided, to acquire the right to which the exercise corresponds to his action: this is called Usucapio.

(Usucapio in case of detention)
Precarious holders or possessors cannot acquire for themselves, by adverse possession, the right held, except when the title of possession is inverted; but, in this case, the time required for adverse possession only starts to run from the title reversal.

(Application of prescription rules)
