Heirs fall into three categories: those entitled to fixed shares, the residuaries, and the uterine relatives ⦗1⦘.

The fixed shares determined by the Law are six: one-half, one-quarter, one-eighth, two-thirds, one-third, and one-sixth.

Those who receive these shares, in brief, are ten: the two spouses; the two parents; the grandfather; any grandmother; any sister; the daughter; the son’s daughter; and the uterine brother.

One-half is allotted to five:

1. the husband, when the deceased wife has left no inheriting descendant;
2. the daughter;
3. the son’s daughter, when there are no direct children;
4. the full sister, when no inheriting descendant exists; and
5. the consanguine sister (sister through the father) in the absence of full brothers.

One-quarter is allotted to two: the husband when the deceased leaves inheriting descendants, and the wife—or wives collectively—when no such descendant exists.

One-eighth is allotted to a single category: the wife, whether one or more collectively, when the deceased leaves inheriting descendants.
