The Rule on ‘Preterition’ (Omission of Compulsory Heirs)

March 21, 2026

SUBJECT: The Rule on ‘Preterition’ (Omission of Compulsory Heirs)

I. Introduction

This memorandum provides an exhaustive analysis of the rule on preterition under Philippine civil law. Preterition refers to the omission in the testator’s will of one, some, or all of the compulsory heirs in the direct line, whether living at the time of the execution of the will or born after the testator’s death. The rule, primarily governed by Article 854 of the Civil Code, is a cornerstone of the protection afforded to compulsory heirs and carries the severe consequence of the annulment of the institution of heirs. This memo will delineate the legal definition, requisites, effects, distinctions from other forms of disinheritance, and pertinent jurisprudence surrounding this rule.

II. Legal Definition and Source

Preterition is defined as the omission of a compulsory heir in the direct line from the will, without being expressly disinherited. Its statutory basis is Article 854 of the Civil Code, which states: “The preterition or omission of one, some, or all of the compulsory heirs in the direct line, whether living at the time of the execution of the will or born after the death of the testator, shall annul the institution of heir; but the devises and legacies shall be valid insofar as they are not inofficious. The compulsory heirs who are not preterited shall be entitled to their legitime in every case.”

III. Requisites of Preterition

For Article 854 to apply, the following elements must concur:

The omitted heir must be a compulsory heir in the direct line. This includes legitimate children and descendants, with respect to their legitimate parents and ascendants; and legitimate parents and ascendants, with respect to their legitimate children and descendants. Illegitimate children are not compulsory heirs in the direct line for purposes of preterition.

The omission must be total. The compulsory heir must receive nothing by will; a mere insufficiency of the share does not constitute preterition.

The omitted heir must not be expressly disinherited. Disinheritance, governed by Articles 915 to 923, is a formal act for a cause specified by law. Preterition is a mere silence or omission.

The omission must occur in a testate succession. The rule does not apply in cases of intestate succession.

IV. Effects of Preterition

The legal effect of preterition is severe and specific:

Annulment of the Institution of Heirs: The entire institution of heirs under the will is annulled. The testate succession is effectively reduced to an intestacy with respect to the hereditary estate, save for the valid devises and legacies.

Validity of Devises and Legacies: Devises and legacies are not invalidated by the preterition, provided they are not inofficious. An inofficious donation is one that impairs the legitime of the compulsory heirs. The devises and legacies must be respected unless they infringe upon the legitime.

Protection of Non-Preterited Compulsory Heirs: Any compulsory heir who was not omitted from the will retains their right to receive their full legitime from the hereditary estate.

Entitlement of the Preterited Heir: The preterited compulsory heir shall inherit their legitime as in intestate succession. The annulment of the institution opens the entire estate to intestate distribution, wherein the preterited heir participates.

V. Distinction from Disinheritance and Pretermitted Heirs

It is crucial to distinguish preterition from related concepts.
Preterition vs. Disinheritance: Disinheritance is a positive act of deprivation for a specific cause authorized by law (Articles 915-923), requires a statement of the cause in the will, and results in the heir losing their right to the legitime. Preterition is a mere omission, requires no cause, and results in the heir receiving their legitime via annulment of the institution.
Preterition vs. Pretermitted Heirs (American Law): The concept of “pretermitted heirs” in many U.S. jurisdictions typically protects children (and sometimes spouses) born or adopted after the execution of a will, granting them an intestate share. Philippine preterition is broader, covering any compulsory heir in the direct line alive at the time of the will’s execution or born thereafter, and triggers annulment, not merely a share.

VI. Jurisprudential Applications and Clarifications

Supreme Court decisions have refined the application of Article 854.

In Añonuevo v. Intestate Estate of Añonuevo, the Court held that the omission of a compulsory heir in the direct line who predeceases the testator is not preterition, as the heir did not survive the testator.

The case of Cuenco v. Court of Appeals clarified that the rule does not apply to compulsory heirs in the collateral line (e.g., brothers and sisters). Their omission does not annul the institution of heirs.

In Reyes v. Barretto-Datu, the Court ruled that if the preterited heir subsequently dies, their heirs can enforce the right to the legitime.

The Court in Testate Estate of Manolita Gonzales v. Court of Appeals emphasized that the annulment is total; partial annulment is not permitted. The entire institution of heirs falls.

VII. Comparative Analysis: Preterition vs. Disinheritance

The following table contrasts the two principal modes of excluding compulsory heirs under Philippine law.

Aspect	Preterition	Disinheritance
Legal Basis	Article 854 of the Civil Code	Articles 915 to 923 of the Civil Code
Nature of Act	Omission or silence in the will.	Positive act of exclusion in the will.
Heirs Covered	Only compulsory heirs in the direct line (legitimate children/descendants, parents/ascendants).	Compulsory heirs in both the direct and collateral lines (includes spouse, illegitimate children).
Requirement of Cause	No cause is required or stated.	A specific cause enumerated in the Civil Code (e.g., maltreatment, conviction of certain crimes) must be stated in the will.
Effect on Heir’s Share	The omitted heir is entitled to their full legitime via intestate succession.	The disinherited heir loses their right to the legitime, unless the disinheritance is void.
Effect on the Will	Annuls the entire institution of heirs; devises/legacies valid if not inofficious.	Does not annul the institution of other heirs; the disinherited heir’s share accrues to other compulsory heirs.
Procedure for Rejection	Heir may enforce right through an action for declaration of preterition and settlement of estate.	Heir may file an action for nullity of disinheritance if cause is false, not stated, or not among those specified by law.

VIII. Exceptions and Special Considerations

Voluntary Heirs: The rule does not apply to the omission of voluntary heirs (e.g., cousins, friends).

Spouse as Compulsory Heir: The legitimate spouse is a compulsory heir but not in the direct line. Omission of the spouse does not constitute preterition under Article 854, though it may give rise to other remedies to protect their legitime.

Illegitimate Children: They are compulsory heirs but are not considered in the direct line for purposes of preterition. Their omission does not trigger Article 854.

Remedial Nature: An action based on preterition is imprescriptible, as it pertains to the very validity of the testate proceedings and the right to legitime.

IX. Procedural Implications

In estate settlement proceedings, a claim of preterition is a serious challenge to the probate of the will. While the will itself may be valid in form, its dispositive portion is rendered ineffective regarding the institution of heirs. The probate court must determine if preterition exists. If so, the estate should be distributed as in intestate succession, after first satisfying the valid devises and legacies that are not inofficious.

X. Conclusion

The rule on preterition serves as a powerful safeguard for compulsory heirs in the direct line, ensuring they cannot be wholly deprived of their legitime by mere omission. Its effect-the annulment of the institution of heirs-underscores the mandatory nature of the legitime in Philippine succession law. Practitioners must carefully distinguish it from disinheritance, ensure that all such compulsory heirs are either instituted, expressly disinherited for a lawful cause, or, if omitted, understand that the will risks substantial nullification. Proper estate planning requires meticulous attention to these mandatory provisions to avoid the unintended consequences of preterition.
