Acts of Alteration in Co-ownership

None of the co-owners shall, without the consent of the others, make alterations in the thing owned in common, even though benefits for all will result therefrom. However, if the withholding of the consent of one or more of the co-owners is clearly prejudicial to the common interest, the courts may afford adequate relief. (Art. 491 of the Civil Code) An alteration is a change which is more or less permanent, changes the use of the thing, and prejudices the condition of the thing or its enjoyment by the others.
