The undivided co-owners may agree that, on the death of one of them, each of the survivors may acquire the share of the deceased, or that the surviving spouse, or any other designated heir, may have it allocated to them on condition that it is taken into account in the estate according to its value at the time of acquisition or allocation.
If several undivided co-owners or several heirs simultaneously exercise their option to acquire or allocate, they are deemed, unless otherwise agreed, to acquire the deceased’s share together in proportion to their respective rights in the undivided co-ownership or the estate.
The provisions of this article may not prejudice the application of the provisions of articles 831 to 832-2.
