English translation

Where a person dies without having made a will, or if having made a will, his will has no effect, the whole of his estate shall be distributed among his statutory heirs according to the law. Where a person dies having made a will which disposes of or has effect for a part only of his estate, the part which has not been disposed of or is not affected by the will shall be distributed among his statutory heirs according to the law.

Firm annotation

Section 1620 (with §1629) sets the intestate-succession order: (1) descendants; (2) parents; (3) full siblings; (4) half-siblings; (5) grandparents; (6) uncles and aunts. The surviving spouse takes a share alongside whatever class inherits (§1635), not a separate class. "Higher excludes lower" — if any class-1 descendants survive, classes 2-6 take nothing. SC decisions 5902/2567 and 4746/2568 confirm that adopted children (under the §1598/19 adoption regime) count as class-1 heirs equal to biological children.
