2792. The following three classes will inherit from a deceased owing to cognateness:
1. The mother, father and the children of the deceased. If no children are present, his grandchildren regardless of their generation will inherit from him, and among them the generation that is closest to the deceased. As long as one person from this class is present, the second class will not inherit from the deceased.
2. The grandfather, grandmother, sister and brother. In the absence of a brother or sister, their children will inherit from the deceased, and amongst them the ones who are closest to the deceased. As long as one person from this class is present, the third class will not inherit from the deceased.
3. The paternal uncle and aunts, and the maternal uncle and aunts. As long as one of the paternal uncle and aunts, or the maternal uncles and aunts are alive, none of their children will inherit from the deceased. However, if the only heirs of the deceased are the paternal step uncle and the son of a paternal uncle, then the inheritance will go to the son of the paternal uncle and not the paternal step uncle. In a case other than this, especially when two maternal uncles or aunts are also present with them, the obligatory precaution is that they should reach a settlement compromise.

2793. In the absence of the paternal uncles and aunts of the deceased, and his maternal uncles and aunts, and in the absence of their children, including any successive generations, the paternal uncles and aunts of his parents, and their maternal uncles and aunts will inherit from him. If they are not present either, their children will inherit from him. If they are not present either, the paternal uncles and aunts of the grandmother and grandfather, and their maternal uncles and aunts will inherit from him. If they too are not present, their children will inherit from him.

2794. A husband and wife inherit from each other, in a manner that will be elaborated in later articles.
