How are taken the decisions within the co-ownership?

A meeting of co-owners must be held each year. The quorum at this meeting is constituted by the co-owners having a majority of the votes. This quorum is necessary to hold the meeting. Some decisions, such as amendments to the by-laws, are taken by a simple majority of votes (50% +1), while other decisions, for example acquisition, construction work or alienation acts, must be taken by co-owners representing three quarters (3/4) of votes of the co-owners present or represented. A majority of three-quarters of the co-owners representing 90% of the votes is required for the decisions modifying the destination, alienating a common portion or modifying the declaration of co-ownership. It is forbidden to change towards a reduction, through by-laws, the required number of votes to take a decision.
