By the provisions of Article 657 (2) of the Civil Code it is regulated the situation in which the destruction of a smaller part of a building takes place, destruction that does not affect the building as a whole nor in a proportion of no more than half of its value, in which situation the co-owners are bound to contribute to the restoration of the common parts proportionally to the quota-share of each of them. The law establishes the obligativity of those co-owners who either do not want or can not participate in the restoration, to assign the quota-shares of the right of forced joint ownership to the other co-owners, meaning that it establishes a modality of extinguishing the right of private property, which, in our opinion, is likely to give rise to some situations that are hard to accept.
