I. Introduction

This memorandum provides an exhaustive analysis of the concept of intestate succession under the Philippine Civil Code, specifically focusing on when it takes place and the governing rules from Article 978 to Article 1014. Intestate succession is a legal mechanism that operates by default, distributing the estate of a deceased person who failed to execute a valid will or whose will is void or inoperative. Its primary purpose is to give effect to the presumed will of the decedent by distributing the property to the closest relatives according to a fixed order established by law.

II. Definition and Conceptual Foundation

Intestate succession is defined as that which takes place by operation of law when: (1) a person dies without a valid will; (2) a person dies with a void will; or (3) a person dies with a valid will, but it has been subsequently revoked, or it does not dispose of all the hereditary estate, resulting in a vacant inheritance for the undisposed portion. It is a system of compulsory succession, where the law itself designates the heirs, their shares, and the order in which they are called to inherit. The underlying principles are the presumed affection of the decedent for relatives, the preservation of wealth within the family, and the state’s interest in preventing estates from becoming vacant.

III. When Intestate Succession Takes Place

Pursuant to Article 960 of the Civil Code, intestate succession takes place under the following specific circumstances:

IV. The Rule on the Order of Intestate Succession: General Principles

The order is exclusive, sequential, and based on proximity of relationship and the principle of right of representation. The law establishes a strict hierarchy where the presence of a relative in a prior order excludes all those in subsequent orders. The primary classes are: (1) Legitimate Descendants; (2) Legitimate Ascendants and Illegitimate Children; (3) Illegitimate Ascendants; (4) Surviving Spouse; (5) Collateral Relatives; (6) The State. Furthermore, the rule of proximity governs within each class, preferring the nearest degree of relationship over the more remote.

V. Detailed Analysis of the Order of Succession (Articles 978-1014)

Article 978: Succession pertains, first, to the descendants.
Article 979: Children and descendants succeed per stirpes, with right of representation taking place indefinitely.
Article 980: In default of legitimate descendants, the ascendants inherit to the exclusion of collateral relatives.
Article 983: The father and mother inherit equally. If only one survives, that parent inherits the entire share.
Article 984: In default of father and mother, the surviving ascendants of the nearest degree inherit, without distinction of lines.
Article 988: In default of legitimate descendants and ascendants, the illegitimate children succeed.
Article 989: In default of illegitimate children, the illegitimate parents succeed.
Article 990: The surviving spouse inherits in concurrence with legitimate parents or illegitimate children, and in default of all of the above, solely.
Article 995: In default of all the foregoing, collateral relatives succeed, with the rule of proximity applying, but with preference given to the paternal line in equal degrees.
Article 1003: In default of persons entitled to succeed, the inheritance passes to the State.

VI. Key Doctrines and Legal Mechanisms

Right of Representation: A right created by fiction of law where the representative steps into the shoes of the person represented (Article 970). It takes place in the direct descending line, always, and in the collateral line, only in favor of the children of brothers or sisters (Article 971). It allows descendants of a predeceased, repudiating, or incapacitated heir to inherit the share their parent would have received.
Per Stirpes Distribution: Inheritance by roots or stocks. The estate is divided by the number of representative lines, not by the number of individual heirs at the same level.
Vacant Inheritance: An inheritance is deemed vacant when no one claims it, either because there are no known heirs, or the heirs have repudiated it. It escheats to the State (Article 1014).
Accretion: The right by which, when several heirs are called to an inheritance, the share of one who repudiates it is added to the shares of the others (Article 1015).

VII. Comparative Table: Intestate Share of Surviving Spouse

The share of the surviving spouse varies significantly depending on the concurring heirs.

VIII. Procedural Aspects and Repudiation

The rights of intestate heirs are transmitted from the moment of death of the decedent (Article 777). An heir may accept or repudiate the inheritance. Repudiation must be express and made in a public or authentic instrument, or in a petition presented to the court having jurisdiction over the estate (Article 1051). The effects of repudiation redound to the benefit of the other co-heirs by accretion or pass to the person(s) next in the order of succession.

IX. Relevant Jurisprudence and Doctrinal Interpretations

The Supreme Court has consistently held that the order of intestate succession is mandatory. In Guevara vs. Guevara, the Court emphasized that the law does not grant the decedent the liberty to choose intestate heirs; the law itself makes the designation. Furthermore, in Estate of Hemady vs. Luzon Surety Co., Inc., the Court ruled that liabilities as well as assets are transmitted to the heirs upon the death of the decedent. The principle of right of representation was extensively discussed in Perez vs. Perez, clarifying its application in the collateral line only extends to children of brothers or sisters.

X. Conclusion

Intestate succession is the default statutory scheme that governs the devolution of a hereditary estate in the absence of a valid testamentary disposition. It takes place under the specific conditions enumerated in Article 960. The order established from Articles 978 to 1014 is rigid, proceeding from descendants to ascendants, then to the surviving spouse, collateral relatives, and finally the State. Critical to its operation are the doctrines of right of representation and per stirpes distribution. The share of the surviving spouse is particularly variable, depending on the class of concurring heirs. Understanding this order is fundamental for determining rightful heirs, computing legitimate shares, and administering estates in the Philippine legal system.
