In that which you leave , their ( your wives ) share is a fourth if you leave no child ; but if you leave a child , they get an eighth of that which you leave after payment of legacies that you may have bequeathed or debts . If the man or woman whose inheritance is in question has left neither ascendants nor descendants , but has left a brother or a sister , each one of the two gets a sixth ; but if more than two , they share in a third ; after payment of lagacies he ( or she ) may have bequeathed or debts , so that no loss is caused ( to anyone ) .
