In the event that the spouse leaves children or descendants, whether or not of the marriage, he or she may dispose in favour of the other spouse either of the ownership of what he or she could dispose of in favour of a stranger, or of one quarter of his or her property in ownership and the other three quarters in usufruct, or of all of his or her property in usufruct only.
Unless otherwise stipulated by the settlor, the surviving spouse may limit his or her emolument to part of the property disposed of in his or her favour. This limitation cannot be considered as a liberality made to the other successors.
