Inheritance Rights for Illegitimate Children under Philippine Law
An Overview

1. Introduction

In Philippine law, the rights of illegitimate children (sometimes referred to as “non-marital” children or those born outside a valid marriage) have undergone significant developments. These rights, particularly in matters of inheritance, are primarily governed by the Civil Code of the Philippines (Republic Act No. 386, as amended) and the Family Code of the Philippines (Executive Order No. 209), as well as related legislation and jurisprudence. This article provides a comprehensive overview of how the law treats inheritance rights of illegitimate children, their entitlement and limitations, and the legal processes involved in asserting their rights.

2. Definition of Illegitimate Children

Under Philippine law, a child is considered illegitimate if born outside a valid marriage. If a child is born to parents who are not legally married or whose marriage is void or voidable at the time of the child’s birth, that child is classified as an illegitimate child.

2.1 Relevant Provisions

Family Code, Article 165: “Children conceived and born outside a valid marriage are illegitimate, unless otherwise provided in this Code.”

3. Basis of Inheritance Rights

Illegitimate children have rights to inherit from their biological parents by virtue of:

The Philippine Constitution, which recognizes the fundamental equality of children before the law.
Statutory provisions under the Civil Code and the Family Code, which ensure certain protections and shares for illegitimate children in their parents’ estates.
Republic Act No. 9255 (2004), which clarifies the use of the father’s surname for illegitimate children under certain conditions, indirectly supporting recognition but not altering the essence of inheritance entitlements.

4. Recognition and Proof of Filiation

To claim inheritance, an illegitimate child must establish filiation (i.e., the legal relationship of parent and child).

Voluntary Recognition: This may be done in the record of birth (e.g., birth certificate), in a will, statement before a court, or any authentic writing acknowledging the child as one’s own.
Compulsory Recognition (Judicial Action): An illegitimate child (or the child’s guardian) may file a case to compel recognition if there is enough evidence (e.g., DNA evidence, proof of open and continuous possession of status, or other relevant documents).

Important: In inheritance proceedings, a child who is not duly recognized can still prove filiation by competent evidence, subject to the applicable rules of court and prescription periods.

5. Share of Inheritance (Legitime)

The legitime is the portion of a deceased person’s estate reserved by law for certain compulsory heirs. Under the Civil Code, illegitimate children are considered compulsory heirs but their share is smaller than that of legitimate children.

5.1 General Rule: Half the Share of a Legitimate Child

Article 895 of the Civil Code: “The legitime of each illegitimate child shall consist of one-half of the legitime of a legitimate child.”

In other words, if a legitimate child is entitled by law to a certain fraction of the estate, an illegitimate child is entitled to half of that fraction as his or her legitime.

5.2 Example

Suppose the decedent leaves behind:

One (1) legitimate child
One (1) illegitimate child

If the legitimate child’s legitime (the legal minimum share) is, say, ( X ) portion of the estate, the illegitimate child’s legitime is ( X/2 ). The exact computation may vary based on the presence of other heirs (e.g., spouse, other children).

6. Other Limitations on Illegitimate Children (Article 992)

An important, often-cited provision is Article 992 of the Civil Code, which states:

“An illegitimate child has no right to inherit ab intestato from the legitimate relatives of his father or mother; nor shall such relatives inherit in the same way from the illegitimate child.”

This means:

An illegitimate child generally cannot inherit from the legitimate grandparents or half-siblings (legitimate siblings) of his or her father or mother unless certain exceptional circumstances apply (e.g., adoption, or if the laws on representation in succession otherwise provide specific allowances).
The prohibition on “collateral” succession remains a significant limitation: while an illegitimate child can inherit directly from the father or mother upon proof of filiation, they cannot inherit from the legitimate relatives of that parent (e.g., legitimate grandparents, uncles/aunts) by operation of law if the parent is not around to pass on that right of representation.

6.1 Rationale

The law historically sought to protect the “legitimacy” of families and to prevent co-mingling of illegitimate and legitimate lines in intestate succession. However, these rules have been subject to criticism for alleged discrimination. As of this writing, Article 992 remains effective law.

7. Inheritance Procedure and Enforcement

7.1 Extrajudicial Settlement or Judicial Proceedings

If the decedent’s estate is settled extrajudicially, the recognized illegitimate child may be included in the settlement.
If judicial (i.e., through a special proceeding for settlement of estate), the illegitimate child must file a claim or participate in the proceedings to assert his or her inheritance rights.

7.2 Action for Declaration of Heirship

When the status of the child as heir is challenged or unclear, a petition for judicial declaration of heirship or an action for recognition may be required. The court will examine evidence of filiation and determine if the child is a compulsory heir entitled to a share.

7.3 Prescription Periods

An action to claim inheritance generally prescribes in the sense that:

A claim for filiation or recognition must be brought within the time frames set by law. Under the Family Code, an action for recognition is generally imprescriptible during the father’s (or mother’s) lifetime; but once the parent has passed away, certain prescriptive rules on inheritance and estate settlement apply (often up to periods like 5 years or 10 years, depending on the nature of the claim).

8. Grounds for Disinheritance

Under certain extraordinary circumstances, even compulsory heirs—including illegitimate children—can be disinherited. The grounds for disinheritance are specified by law (e.g., committing acts of violence against the testator, false accusations of crimes, etc.). However, these grounds apply equally to legitimate and illegitimate children; illegitimate children cannot be singled out for disinheritance merely based on their status.

9. RA 9255 (Using Father’s Surname)

Republic Act No. 9255 (2004) amended Article 176 of the Family Code to allow illegitimate children to use the surname of their father under certain conditions (e.g., through an Affidavit of Acknowledgment/Affidavit of Admission of Paternity).

Key Point: This law does not expand or restrict the inheritance rights directly. Rather, it simplifies formal recognition and confers certain privileges related to surnames, which can help in establishing proof of filiation. Once an illegitimate child is publicly acknowledged, it becomes simpler to prove inheritance claims.

10. Legitimation vs. Recognition

Philippine law also provides a process of legitimation under certain conditions—specifically, if the child is born to parents who, at the time of conception, were not disqualified from marrying each other, and the parents subsequently legally marry. This transforms the child’s status from illegitimate to legitimate.

Effect on Inheritance: Once legitimated, the child’s inheritance rights become equivalent to that of a legitimate child.
Limits of Legitimation: If the child was born of parents subject to a legal impediment to marry (e.g., one was married to another person at the time), legitimation is not possible.

11. Key Judicial Interpretations

Over the years, the Supreme Court of the Philippines has emphasized two main points:

Equality of Rights Among Children: Despite legislative distinctions, the courts have generally aimed to uphold the best interests of the child and ensure that illegitimate children’s protected rights (like inheritance) are not curtailed by technicalities.
Strict Adherence to Statutory Limitations: Courts continue to enforce Article 992’s prohibition on succession between illegitimate children and their parents’ legitimate relatives, absent a legislative amendment. Legislative reforms have been proposed but have not yet significantly altered Article 992.

12. Practical Considerations and Tips

Timely Recognition: If you are a parent of an illegitimate child, or if you are an illegitimate child seeking inheritance rights, secure documentation (birth certificate with the father’s signature, an affidavit of acknowledgment, or other authentic documents).
Extrajudicial Settlement: Where possible, settle the estate amicably with all heirs to avoid protracted court proceedings.
Court Action: If filiation is in dispute, be prepared to file (or defend) a petition to establish paternity/maternity and heirship. DNA evidence can play a crucial role.
Consult Legal Counsel: Each estate situation can be unique. Legal advice is essential to navigate deadlines, procedural requirements, and to properly compute shares.

13. Conclusion

Illegitimate children in the Philippines are compulsory heirs of their biological parents and, as such, are protected by law in claiming their rightful share of the inheritance. While the basic rule remains that an illegitimate child’s legitime is half the share of a legitimate child, the child must first prove filiation to enforce this right. Moreover, Article 992 still imposes notable restrictions on inheritance from legitimate relatives of the parent. Despite progressive developments (e.g., RA 9255 facilitating use of the father’s surname and recognition), the law still retains certain distinctions between legitimate and illegitimate children in collateral lines of succession.

Nonetheless, the general trajectory of Philippine jurisprudence and legislation has been to encourage recognition and to lessen the stigma historically associated with illegitimacy. Future legislative reforms could further broaden the inheritance rights of illegitimate children, but as of the date of writing, the principles outlined herein govern their legal entitlements.
