I. Introduction

In Philippine succession law, an illegitimate child is not a stranger to the estate of his or her parent. The law expressly recognizes the hereditary rights of illegitimate children, although their shares are generally smaller than those of legitimate children. The fact that the property involved was inherited by the parent does not, by itself, prevent the illegitimate child from inheriting it.

The controlling principle is this: once property becomes part of the parent’s estate, the illegitimate child may inherit from that parent, subject to the Civil Code, the Family Code, the rules on legitime, intestacy, testamentary succession, and special restrictions such as reserva troncal.

The harder questions usually arise when the illegitimate child is not claiming from the parent directly, but from the parent’s legitimate relatives, such as grandparents, legitimate siblings, aunts, uncles, or cousins. In that situation, the so-called “iron curtain rule” under Article 992 of the Civil Code becomes central.

II. Basic Legal Status of Illegitimate Children

Under Philippine law, a child is generally either legitimate or illegitimate.

A child is legitimate if conceived or born during a valid marriage of the parents, subject to the rules of the Family Code. A child who does not fall within the legal definition of legitimate is generally considered illegitimate.

Illegitimacy does not mean absence of rights. Illegitimate children have rights to:

support;
use of surname under applicable law;
proof and recognition of filiation;
compulsory heirship;
legitime;
intestate succession from their parent;
succession to property forming part of the parent’s estate, including property the parent inherited.

The principal difference is that an illegitimate child’s successional share is generally one-half of the share of a legitimate child, and illegitimate children are subject to certain restrictions when dealing with the legitimate relatives of their parents.

III. The Core Rule: An Illegitimate Child Inherits From His or Her Parent

The most important rule is direct and straightforward:

An illegitimate child is a compulsory heir of his or her parent.

This means that the parent cannot freely dispose of the entire estate in a way that completely deprives the illegitimate child of the legitime granted by law.

Under Article 887 of the Civil Code, compulsory heirs include legitimate children and descendants, legitimate parents and ascendants in proper cases, the surviving spouse, and illegitimate children. Under Article 176 of the Family Code, the legitime of each illegitimate child is one-half of the legitime of a legitimate child.

Therefore, when a parent dies, the illegitimate child may inherit from that parent whether the parent’s property was:

purchased by the parent;
earned by the parent;
donated to the parent;
received as compensation;
acquired during marriage;
inherited from the parent’s own parents or relatives;
inherited from any other person.

The source of the property is generally immaterial once it has become part of the deceased parent’s estate.

IV. Property Inherited by the Parent Becomes Part of the Parent’s Estate

When a person inherits property, that property becomes part of his or her patrimony. Upon that person’s death, the property is included in the hereditary estate, unless it has been sold, transferred, lost, donated, partitioned, or otherwise disposed of during the parent’s lifetime.

Thus, if a father inherited a parcel of land from his own mother, and later the father dies, his illegitimate child may inherit from the father’s estate. The child is not inheriting directly from the grandmother. The child is inheriting from the father.

That distinction matters.

Example

A grandmother dies and leaves land to her son. The son becomes the owner of the land. Later, the son dies, leaving one legitimate child and one illegitimate child.

The illegitimate child may inherit from the son’s estate. The inherited land is included in the son’s estate because it became his property before he died.

The illegitimate child’s claim is against the father’s estate, not against the grandmother’s estate.

V. When the Parent Already Inherited Before Death

If the parent was alive when the original owner died, the parent’s hereditary rights generally vested at the moment of the original owner’s death.

Article 777 of the Civil Code provides that the rights to succession are transmitted from the moment of death.

This means that if the parent survived the original decedent, even briefly, the parent acquired successional rights. Those rights may later pass to the parent’s own heirs, including illegitimate children.

Example

A grandfather dies on January 1. His son, who is an heir, dies on February 1. The son leaves an illegitimate child.

Because the son was alive when the grandfather died, the son acquired hereditary rights from the grandfather. When the son later died, those rights formed part of the son’s estate. The illegitimate child may inherit those rights from the son.

This is not the same as the illegitimate child directly representing the son in the grandfather’s estate. The son already acquired the rights before he died.

VI. When the Parent Predeceased the Original Owner

The result is different if the parent died before the original owner.

Example

A son dies in 2020. His father, the grandfather, dies in 2025. The son left an illegitimate child. The question is whether the illegitimate grandchild may inherit from the grandfather by representing the predeceased son.

This is where Article 992 of the Civil Code becomes important.

Article 992 provides:

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

This is commonly called the iron curtain rule because it creates a legal barrier between an illegitimate child and the legitimate family of the child’s parent in intestate succession.

Traditionally, this rule has been understood to mean that an illegitimate child generally cannot inherit by intestacy from the legitimate relatives of his or her parent, including legitimate grandparents, legitimate siblings of the parent, and other legitimate collateral relatives.

Therefore, if the parent died before the grandparent, and the illegitimate child is trying to inherit directly from the grandparent by right of representation, Article 992 may bar the claim, especially where the grandparent is a legitimate relative of the parent.

VII. The Important Distinction: Inheriting From the Parent vs. Inheriting From the Parent’s Relatives

The distinction is crucial:

A. Allowed: Illegitimate Child Inherits From the Parent

If the property already belonged to the parent when the parent died, the illegitimate child may inherit from the parent.

This includes property the parent inherited.

B. Generally Barred: Illegitimate Child Inherits Directly From Legitimate Relatives of the Parent by Intestacy

If the illegitimate child is claiming directly from the legitimate relatives of the parent, Article 992 may apply.

This is not because the child has no rights. It is because the law restricts intestate succession between illegitimate children and the legitimate family line of the parent.

Practical Illustration

Scenario 1: Parent inherited first.

Grandfather dies. Father inherits land. Father later dies. Illegitimate child claims from father.

Result: The illegitimate child may inherit from the father.

Scenario 2: Parent died first.

Father dies. Grandfather later dies. Illegitimate child claims from grandfather by representing father.

Result: The claim may be barred by Article 992 if the grandfather is part of the legitimate family line.

VIII. Testamentary Succession: A Parent May Give More, But Not Less Than the Legitime

A parent may execute a will and give property to an illegitimate child. The parent may even give the illegitimate child more than the legal legitime, provided that the legitimes of other compulsory heirs are not impaired.

In testamentary succession, the parent’s estate is divided into portions:

the legitime reserved by law for compulsory heirs;
the free portion, which the testator may generally dispose of by will.

An illegitimate child is entitled to his or her legitime. The parent cannot deprive the illegitimate child of that legitime except by a valid cause for disinheritance.

If the parent gives the illegitimate child more than the legitime, the excess is valid so long as it does not impair the legitime of other compulsory heirs.

IX. The Legitime of an Illegitimate Child

The legitime of each illegitimate child is generally one-half of the legitime of a legitimate child.

This does not always mean one-half of the estate. It means one-half of the share that a legitimate child receives as legitime.

Example

A parent dies leaving two legitimate children and one illegitimate child.

The legitimate children are compulsory heirs. The illegitimate child is also a compulsory heir.

If the estate is divided according to compulsory shares, each illegitimate child’s legitime is computed as one-half of the legitime of each legitimate child, subject to the rule that the legitimes must fit within the estate and that the legitime of legitimate children must not be impaired.

The illegitimate child’s share is not equal to the legitimate child’s share. It is generally half.

X. Intestate Succession: When the Parent Dies Without a Will

If the parent dies without a will, the rules on intestate succession apply.

The share of the illegitimate child depends on who else survives the deceased parent.

Common situations include the following.

XI. Parent Leaves Legitimate Children and Illegitimate Children

When legitimate children and illegitimate children survive, each illegitimate child is generally entitled to a share equal to one-half of the share of each legitimate child.

Example

The deceased parent leaves:

one legitimate child;
one illegitimate child;
no surviving spouse.

The legitimate child receives twice the share of the illegitimate child.

If the estate is ₱3,000,000, the legitimate child receives ₱2,000,000 and the illegitimate child receives ₱1,000,000.

XII. Parent Leaves Several Legitimate and Illegitimate Children

Example

The deceased leaves:

two legitimate children;
two illegitimate children;
no surviving spouse.

Each legitimate child receives a full share. Each illegitimate child receives one-half share.

The ratio is:

legitimate child A: 1 share;
legitimate child B: 1 share;
illegitimate child C: 1/2 share;
illegitimate child D: 1/2 share.

Total shares: 3.

If the estate is ₱6,000,000:

each legitimate child receives ₱2,000,000;
each illegitimate child receives ₱1,000,000.

XIII. Parent Leaves a Surviving Spouse, Legitimate Children, and Illegitimate Children

Where a surviving spouse, legitimate children, and illegitimate children all survive, the surviving spouse generally receives a share equal to that of one legitimate child, while each illegitimate child receives one-half of the share of a legitimate child.

Example

The deceased leaves:

surviving spouse;
two legitimate children;
one illegitimate child.

The ratio is:

spouse: 1 share;
legitimate child A: 1 share;
legitimate child B: 1 share;
illegitimate child: 1/2 share.

Total shares: 3.5.

If the estate is ₱7,000,000:

spouse receives ₱2,000,000;
each legitimate child receives ₱2,000,000;
illegitimate child receives ₱1,000,000.

XIV. Parent Leaves Only Illegitimate Children

If the parent dies leaving illegitimate children but no legitimate descendants, no legitimate ascendants, and no surviving spouse, the illegitimate children may inherit the entire estate.

Example

A mother dies without a will. She leaves no spouse, no legitimate child, no surviving parent, and two illegitimate children.

The two illegitimate children divide the estate equally.

If the estate is ₱4,000,000, each receives ₱2,000,000.

XV. Parent Leaves a Surviving Spouse and Illegitimate Children Only

If the deceased parent leaves a surviving spouse and illegitimate children, but no legitimate children or legitimate parents, the surviving spouse and illegitimate children generally share the estate according to the Civil Code rules.

A common rule applied is that the surviving spouse receives one-half and the illegitimate children receive the other half, subject to the specific circumstances and applicable provisions.

Example

The deceased leaves:

surviving spouse;
two illegitimate children;
no legitimate children;
no legitimate parents.

If the estate is ₱6,000,000:

spouse receives ₱3,000,000;
illegitimate children share ₱3,000,000;
each illegitimate child receives ₱1,500,000.

XVI. Parent Leaves Legitimate Parents and Illegitimate Children

If the deceased leaves legitimate parents or ascendants and illegitimate children, but no legitimate children, the shares are governed by the Civil Code provisions on concurrence of legitimate ascendants and illegitimate children.

Generally, legitimate parents or ascendants receive a reserved share, while illegitimate children also receive a legally recognized portion.

The exact division depends on whether a surviving spouse also exists.

XVII. Property Inherited by the Parent From a Grandparent

This is one of the most common real-life situations.

Situation

A father inherits land from his father. The father later dies. He leaves an illegitimate child.

Rule

The illegitimate child may inherit from the father because the land became the father’s property.

The illegitimate child is not being treated as an heir of the grandfather. The child is an heir of the father.

Consequence

The land is included in the father’s estate. The illegitimate child’s share is computed together with the shares of the father’s other heirs.

XVIII. Property Still Undivided in the Estate of the Grandparent

Sometimes the parent inherited from a grandparent, but the estate of the grandparent has not yet been partitioned.

Example

Grandfather died owning land. Father was one of the heirs. No partition was made. Father later died, leaving an illegitimate child.

The father’s hereditary share in the grandfather’s estate forms part of the father’s own estate. The illegitimate child may inherit the father’s hereditary rights.

In practice, the illegitimate child may participate in settlement proceedings involving the parent’s estate and may assert the parent’s share in the earlier estate, but the child’s right flows through the parent, not directly from the grandparent.

XIX. Co-Owned Inherited Property

Inherited property often remains co-owned among heirs.

If the parent was a co-owner of inherited property, the illegitimate child may inherit only the parent’s share, not the entire property.

Example

A mother inherited one-fourth of a parcel of land from her parents. She later died leaving an illegitimate child.

The illegitimate child may inherit from the mother’s one-fourth share, subject to the rights of the mother’s other heirs.

The child does not become owner of the entire parcel. The child steps into the mother’s patrimonial position as to the share inherited by the mother.

XX. The Illegitimate Child Does Not Automatically Own the Specific Property

A common misconception is that if the parent dies owning inherited land, the illegitimate child automatically owns a specific portion of that land.

In succession law, heirs generally inherit an ideal or undivided share in the estate before partition. Until partition, the heirs are usually co-owners of the estate property.

The illegitimate child may be entitled to a share in the estate, but the exact property to be assigned may be determined only after:

inventory;
payment of debts;
determination of heirs;
collation, if applicable;
computation of legitimes;
partition;
registration or transfer of title, if real property is involved.

XXI. Proof of Filiation Is Essential

An illegitimate child must prove filiation to inherit.

Under the Family Code, filiation may be established through:

the record of birth appearing in the civil register;
an admission of filiation in a public document;
an admission of filiation in a private handwritten instrument signed by the parent;
other evidence allowed by the Rules of Court and jurisprudence, subject to the rules on when the action may be brought.

Proof of filiation is often the decisive issue in inheritance disputes.

An alleged illegitimate child cannot simply claim inheritance by alleging biological relationship. The relationship must be legally proven.

XXII. Recognition Is Not Always the Same as Biological Truth

Philippine succession law deals with legally established filiation, not mere biological possibility.

DNA evidence may be relevant in proper cases, but legal filiation still has to be established according to the Family Code and procedural rules.

The estate, legitimate heirs, or other interested parties may contest the claim if filiation is not sufficiently proven.

XXIII. When the Parent Acknowledged the Child

If the parent acknowledged the child in a birth certificate, public instrument, notarized document, written admission, or other legally acceptable form, the child has a stronger basis to claim inheritance.

However, disputes may still arise regarding:

authenticity of documents;
identity of the child;
whether the alleged parent signed the document;
whether the admission was clear;
whether the action to establish filiation was filed on time;
whether the claim is barred by prescription, laches, or procedural rules.

XXIV. The Role of the Birth Certificate

A birth certificate may be powerful evidence of filiation, especially if signed or acknowledged by the parent.

However, a birth certificate that merely names a person as the father, without the father’s participation or signature, may not always be sufficient by itself.

The evidentiary value depends on the circumstances.

For inheritance purposes, courts look at whether filiation was legally established, not merely asserted.

XXV. Illegitimate Children and the “Iron Curtain Rule”

Article 992 of the Civil Code is one of the most controversial provisions in Philippine succession law.

It provides that an illegitimate child has no right to inherit ab intestato from the legitimate children and relatives of his or her father or mother, and vice versa.

The rule applies to intestate succession, meaning succession without a will.

Effect

An illegitimate child may inherit from his or her parent, but generally may not inherit by intestacy from the legitimate relatives of that parent.

Examples of persons from whom the illegitimate child may be barred from inheriting by intestacy

legitimate grandparents of the parent’s line;
legitimate siblings of the parent;
legitimate nephews or nieces in that line;
legitimate uncles or aunts;
other legitimate collateral relatives of the parent.

XXVI. Article 992 Does Not Bar Inheritance From the Parent

Article 992 should not be misunderstood.

It does not say that an illegitimate child cannot inherit property that came from the legitimate family. It says that an illegitimate child has no right to inherit ab intestato from the legitimate children and relatives of the parent.

If the property already passed to the parent, and the parent later died, the illegitimate child inherits from the parent.

Thus, the illegitimate child is not disqualified merely because the property originally came from the parent’s legitimate family.

XXVII. Right of Representation

Representation is a legal fiction by which a person succeeds in the place of another heir.

In the direct descending line, representation generally allows descendants to inherit in place of a predeceased parent.

However, Article 992 complicates this when the person seeking to represent is an illegitimate child claiming from a legitimate relative of the parent.

Traditionally, an illegitimate child cannot use representation to inherit by intestacy from the legitimate relatives of the parent if Article 992 applies.

Example

A legitimate grandfather dies. His legitimate son predeceased him. The son left an illegitimate child.

The illegitimate child claims to represent the father in the grandfather’s estate.

Under the traditional application of Article 992, the claim is generally barred because the illegitimate child is attempting to inherit by intestacy from the legitimate relative of the father.

XXVIII. If the Grandparent Left a Will

Article 992 refers to intestate succession. If the grandparent left a valid will giving property to the illegitimate grandchild, the issue may be different.

A person may generally give property by will to a stranger or to a relative, provided that the legitimes of compulsory heirs are not impaired and the devise or legacy is not otherwise prohibited by law.

Thus, even if an illegitimate grandchild may be barred from inheriting by intestacy from a legitimate grandparent, the grandparent may still give property to that illegitimate grandchild by will, subject to the legitime of compulsory heirs.

XXIX. The Parent’s Inherited Property and Reserva Troncal

A special and often overlooked rule is reserva troncal, found in Article 891 of the Civil Code.

Reserva troncal applies when:

an ascendant inherits property from a descendant;
the property was acquired by that descendant from another ascendant or from a brother or sister;
the descendant died without legitimate issue;
the law requires the ascendant who inherited the property to reserve it for relatives within the third degree belonging to the line from which the property came.

Reserva troncal is technical, but it can affect property that moved through inheritance.

Why it matters

If the parent inherited property subject to reserva troncal, the parent’s freedom to pass that property may be limited. The property may have to be reserved for certain relatives of the line of origin.

Effect on illegitimate children

An illegitimate child’s right to inherit from the parent may be affected if the property is reservable. The illegitimate child may still inherit other property from the parent, but the reservable property may be subject to the rights of reservees.

Reserva troncal is one of the main exceptions to the general statement that inherited property simply becomes ordinary property in the parent’s estate.

XXX. Donations Made by the Parent to the Illegitimate Child

A parent may donate property to an illegitimate child during the parent’s lifetime, including property the parent inherited, subject to restrictions.

However, donations may be reduced if they impair the legitime of compulsory heirs.

If the parent donated inherited property to the illegitimate child, legitimate heirs may later question the donation if:

the donation was inofficious;
it impaired legitime;
the donor lacked capacity;
the donation lacked formal requirements;
the property was conjugal or community property and required spousal consent;
the donation was simulated;
the property was subject to reserva troncal or other restrictions.

XXXI. Sale or Transfer of Inherited Property Before Death

If the parent sold the inherited property before death, the illegitimate child generally cannot demand that specific property from the buyer merely because the child is an heir.

During the parent’s lifetime, the child has only an inchoate or expectant right to inherit. Successional rights vest only upon death.

A future heir does not own the parent’s property while the parent is alive.

However, if the sale was simulated, fraudulent, or intended to defeat legitime, it may be challenged in proper proceedings.

XXXII. The Parent Cannot Completely Disinherit an Illegitimate Child Without Legal Cause

Because an illegitimate child is a compulsory heir, the parent cannot simply exclude the child from the legitime.

Disinheritance must be made in a will and must be based on a cause expressly provided by law.

If the disinheritance is invalid, the illegitimate child may still claim the legitime.

XXXIII. Preterition and Illegitimate Children

Preterition occurs when a compulsory heir in the direct line is omitted from a will.

The classic doctrine on preterition is most strongly associated with compulsory heirs in the direct line, especially legitimate children and descendants. The effect of omission may be severe, potentially annulling the institution of heirs, depending on the circumstances.

Where an illegitimate child is omitted, the remedy often involves protection of the legitime and reduction of testamentary dispositions, rather than automatically treating the child as having no rights.

The precise effect depends on the facts, the wording of the will, and the compulsory heirs involved.

XXXIV. Collation and Advances

If the illegitimate child received donations or advances from the parent during the parent’s lifetime, those may be considered in computing the estate.

Collation is the process of bringing into the hereditary estate certain donations or advances received by heirs so that legitimes and shares may be properly computed.

If the parent gave substantial property to an illegitimate child before death, other heirs may argue that it should be charged against the child’s legitime or share.

XXXV. Illegitimate Child’s Rights in Settlement Proceedings

An illegitimate child who claims inheritance from a deceased parent may participate in estate settlement proceedings.

The child may seek:

recognition as an heir;
inclusion in the declaration of heirs;
inventory of estate property;
accounting of income from estate property;
partition;
delivery of hereditary share;
annulment or reduction of acts impairing legitime;
correction of extrajudicial settlements that excluded the child.

XXXVI. Extrajudicial Settlement Excluding an Illegitimate Child

If the legitimate heirs execute an extrajudicial settlement and exclude a known illegitimate child, the settlement may be challenged.

An extrajudicial settlement does not destroy the rights of an omitted heir.

The omitted illegitimate child may file the proper action to assert hereditary rights, subject to limitation periods, laches, notice, publication, registration, and rights of innocent purchasers.

XXXVII. Sale of Estate Property Without Including the Illegitimate Child

If co-heirs sell estate property without including an illegitimate child who is also an heir, the sale may affect only the sellers’ shares, not necessarily the share of the excluded heir.

However, land registration, good faith purchase, prescription, laches, and procedural rules may complicate the remedy.

The illegitimate child should assert rights promptly.

XXXVIII. Illegitimate Children and Torrens Titles

If inherited land is registered under the Torrens system, succession does not automatically update the title.

The illegitimate child may need to participate in:

estate settlement;
adjudication;
deed of extrajudicial settlement;
partition agreement;
court proceedings;
payment of estate taxes;
issuance of certificate authorizing registration;
registration with the Register of Deeds;
issuance of new transfer certificates of title.

Being an heir gives a substantive right, but registration is needed to reflect ownership on title.

XXXIX. Estate Tax and Inherited Property

Before inherited property can usually be transferred, estate tax compliance is required.

If the parent inherited property from someone else, there may be multiple estate tax layers:

estate tax on the original decedent’s estate;
estate tax on the parent’s estate.

If the earlier estate was never settled, the heirs of the parent may face practical problems transferring title.

An illegitimate child’s right to inherit exists under succession law, but implementation may require settling both estates.

XL. Illegitimate Child Born After the Parent Inherited Property

If the illegitimate child was born after the parent inherited the property but before the parent’s death, the child may inherit from the parent, provided filiation is established.

The timing of acquisition by the parent does not defeat the child’s successional rights.

The estate is determined at the parent’s death, not at the time the parent acquired each property.

XLI. Illegitimate Child Conceived Before Death but Born After Death

A conceived child may have successional rights if later born under the conditions required by law.

The Civil Code protects conceived children for purposes favorable to them, provided they are later born alive according to law.

Thus, a posthumous illegitimate child may inherit from the deceased parent if filiation and the legal requirements are established.

XLII. Adopted Children and Illegitimate Children

Adoption changes legal relationships for succession purposes.

An adopted child is generally treated as a legitimate child of the adopter for many legal purposes, including succession between adopter and adoptee.

However, adoption may affect succession between the child and biological relatives depending on the applicable adoption law and circumstances.

If an illegitimate child is adopted by the parent or by another person, succession issues must be analyzed carefully.

XLIII. Legitimation

An illegitimate child may become legitimated if the parents were not disqualified from marrying each other at the time of the child’s conception and later validly marry, subject to the Family Code.

Once legitimated, the child generally has the same rights as a legitimate child.

This can significantly affect inheritance because the child’s share may increase from that of an illegitimate child to that of a legitimate child.

XLIV. Use of the Father’s Surname Does Not Automatically Prove Full Successional Rights

Republic Act No. 9255 allows an illegitimate child to use the father’s surname under certain conditions.

However, use of surname and inheritance are related but not identical issues.

Use of the father’s surname may be evidence of acknowledgment, depending on the documents, but inheritance still requires legally established filiation.

XLV. Rights Against the Mother and Rights Against the Father

An illegitimate child may inherit from both the mother and the father, provided filiation is established.

Filiation with the mother is often easier to prove because maternity is usually reflected in birth records.

Filiation with the father is more frequently contested and may require stronger documentary or testimonial evidence.

XLVI. The Illegitimate Child’s Descendants

The hereditary rights of an illegitimate child may pass to his or her descendants in proper cases.

For example, if an illegitimate child who is entitled to inherit from a parent dies, questions may arise as to whether the illegitimate child’s own children may succeed to those rights.

The answer depends on timing, representation, whether the first heir survived the decedent, and the applicable rules on succession.

XLVII. Distinguishing Transmission From Representation

This distinction is very important.

Transmission

Transmission occurs when an heir survives the decedent, acquires hereditary rights, and then later dies. The heir’s own heirs inherit those rights.

Representation

Representation occurs when a person takes the place of another who could not inherit because of predecease, incapacity, or disinheritance.

For illegitimate children, transmission is often easier to sustain than representation against legitimate relatives of the parent, because Article 992 may bar representation in intestate succession involving legitimate relatives.

XLVIII. Practical Example: Transmission Allowed

Grandmother dies. Father is alive, so he inherits from grandmother. Father later dies. His illegitimate child inherits from father.

This is transmission. The illegitimate child inherits from the father, not directly from grandmother.

XLIX. Practical Example: Representation Barred

Father dies before grandmother. Grandmother later dies without a will. Father’s illegitimate child claims the father’s share by representation.

This may be barred by Article 992 because the child is attempting to inherit by intestacy from the legitimate relative of the father.

L. What If the Parent Renounced the Inheritance?

If the parent validly repudiated or renounced the inheritance from the original decedent, the property or hereditary right may never become part of the parent’s estate.

In that case, the illegitimate child generally cannot inherit that property from the parent because the parent did not acquire it.

However, if the renunciation was fraudulent or intended to prejudice creditors or compulsory heirs, legal remedies may be available in proper cases.

LI. What If the Parent Was Disinherited by the Original Owner?

If the parent was validly disinherited by the original owner, the parent may not have acquired the property. Whether the illegitimate child can claim anything depends on whether representation is available and whether Article 992 or other restrictions apply.

If the original owner was a legitimate relative of the parent, Article 992 may become a barrier to the illegitimate child’s intestate claim.

LII. What If the Parent Was Declared Unworthy?

If the parent was incapacitated or unworthy to inherit from the original decedent, the parent may not acquire the inheritance.

The illegitimate child’s ability to claim depends on representation and other succession rules. Again, Article 992 may bar claims against legitimate relatives of the parent in intestacy.

LIII. What If the Parent’s Inheritance Was Conditional?

If the parent inherited subject to a condition, charge, trust, restriction, or resolutory event, the illegitimate child inherits only whatever rights the parent had.

The child cannot receive better rights than the parent possessed.

If the parent’s ownership was limited, conditional, or burdened, the child’s inherited right is likewise limited.

LIV. Conjugal or Community Property Issues

If the parent was married, property inherited by that parent may be treated differently depending on the property regime.

Under many Philippine property regimes, property acquired by gratuitous title, such as inheritance or donation, may remain exclusive property of the recipient spouse, unless otherwise provided by law, by the donor or testator, or by marriage settlement.

However, income or fruits of inherited property may sometimes be treated differently depending on the applicable property regime.

This affects what enters the estate of the deceased parent.

An illegitimate child inherits only from the deceased parent’s estate, not from the share of the surviving spouse.

LV. Absolute Community of Property

Under the Family Code, spouses married under the default regime of absolute community generally place most property into the community, but certain properties may be excluded, including some property acquired by gratuitous title, depending on the law and conditions imposed.

If inherited property is excluded from the community, it remains the exclusive property of the inheriting spouse.

If it forms part of the community, the deceased parent’s estate may include only the parent’s share after liquidation.

The property regime must be settled before computing inheritance.

LVI. Conjugal Partnership of Gains

Under conjugal partnership, property inherited by one spouse is generally exclusive property of that spouse, but fruits or income may belong to the conjugal partnership depending on the circumstances and governing law.

Before heirs divide the estate, the conjugal partnership must be liquidated.

The illegitimate child inherits only from the deceased parent’s net estate after liquidation.

LVII. The Net Estate Matters

Inheritance is not computed from gross property alone.

Before heirs receive their shares, the estate must account for:

debts;
taxes;
administration expenses;
funeral expenses, where legally chargeable;
claims against the estate;
liquidation of property regime;
ownership disputes;
obligations attached to inherited property.

The illegitimate child’s share is computed from the net estate, not merely from the visible assets.

LVIII. Illegitimate Child’s Right to Accounting

If other heirs possess or manage inherited property of the deceased parent, the illegitimate child may seek accounting.

This is especially important where the property produces income, such as:

rent;
crops;
lease payments;
dividends;
business profits;
proceeds from sale.

As a co-heir, the illegitimate child may be entitled to a proportionate share of fruits or income, subject to estate administration and expenses.

LIX. Prescription and Laches

Although hereditary rights are protected, delay can create problems.

An illegitimate child who sleeps on his or her rights may face defenses such as:

prescription;
laches;
estoppel;
prior settlement;
sale to innocent purchasers;
finality of judgments;
conclusiveness of estate proceedings;
loss or unavailability of evidence of filiation.

Prompt assertion of rights is important.

LX. Common Disputes

Disputes involving illegitimate children and inherited property often involve:

denial of filiation;
exclusion from extrajudicial settlement;
concealment of estate property;
sale of inherited land without consent;
refusal to account for rents or produce;
claims that Article 992 bars the child;
disputes over whether the child is inheriting from the parent or from the parent’s relatives;
disputes over whether the parent had already acquired the inheritance;
questions on legitime;
disputes over wills and donations;
reserva troncal;
forged waivers or deeds;
simulated sales;
land title transfers excluding the child.

LXI. Remedies of an Illegitimate Child

Depending on the facts, remedies may include:

action to establish filiation;
petition for settlement of estate;
intervention in estate proceedings;
action for partition;
action for reconveyance;
action for annulment of deed;
action for reduction of inofficious donations;
action to recover legitime;
accounting;
cancellation or correction of title;
damages, in proper cases;
opposition to probate or settlement, where appropriate.

LXII. Settlement of Estate Where Illegitimate Child Is Known

If the illegitimate child is known and filiation is established, the child should be included in the settlement of the parent’s estate.

A settlement excluding a compulsory heir is vulnerable to attack.

The heirs should determine:

the full list of heirs;
the nature of each child’s filiation;
whether there is a will;
the property regime of the deceased;
the estate assets;
the estate liabilities;
whether properties were inherited, donated, or purchased;
whether any property is reservable;
the legitimes;
the proper partition.

LXIII. Waiver by an Illegitimate Child

An illegitimate child may waive hereditary rights after the parent’s death, subject to legal requirements.

However, future inheritance generally cannot be waived before the death of the parent because rights to succession arise only upon death.

A waiver must be voluntary, valid, and informed. Fraud, intimidation, mistake, minority, incapacity, or lack of formalities may affect validity.

LXIV. Compromise Agreements

Heirs may enter into compromise agreements regarding estate disputes, including claims of illegitimate children.

However, compromises cannot validate illegal acts or defeat mandatory legitimes without proper consent and legal basis.

Court approval may be required in certain proceedings, especially when minors or incapacitated persons are involved.

LXV. Minors Who Are Illegitimate Children

If the illegitimate child is a minor, the child’s inheritance rights must be protected by a parent, guardian, or representative.

Settlements affecting a minor’s hereditary rights may require court approval.

A waiver or compromise prejudicing a minor may be challenged if not properly authorized.

LXVI. Effect of a Will Giving the Inherited Property to Someone Else

If the parent makes a will giving inherited property to another person, the disposition is valid only to the extent that it does not impair the legitime of compulsory heirs, including illegitimate children.

If the will impairs the illegitimate child’s legitime, the child may demand reduction of the testamentary dispositions.

The parent may choose which specific properties to give, but cannot defeat the child’s minimum legal share.

LXVII. Effect of a Will Giving the Inherited Property to the Illegitimate Child

If the parent gives inherited property to the illegitimate child by will, the gift is valid if:

the parent had capacity;
the will complies with formalities;
the property belongs to the parent;
the legitimes of other compulsory heirs are not impaired;
the property is not subject to a legal restriction such as reserva troncal.

The illegitimate child may receive both legitime and additional property from the free portion.

LXVIII. Effect of Disinheritance

A parent may disinherit an illegitimate child only through a valid will and only for causes recognized by law.

If the cause is false, invalid, or not proven, the disinheritance may be ineffective.

A mere statement such as “I leave nothing to my illegitimate child” is not enough if it violates legitime.

LXIX. Illegitimate Children and Siblings

An illegitimate child may inherit from his or her own parent. But inheritance between an illegitimate child and the legitimate children or relatives of the parent is restricted by Article 992 in intestacy.

As between siblings, the rules can be complicated.

A legitimate child of the parent and an illegitimate child of the same parent may inherit together from that parent. But whether they may inherit from each other by intestacy depends on the legal relationship and the Article 992 barrier.

LXX. Illegitimate Child Inheriting From an Illegitimate Parent

If the parent is also illegitimate, the illegitimate child may inherit from that parent.

Article 992 primarily addresses the barrier between illegitimate children and the legitimate children and relatives of their father or mother. Where the succession is directly between parent and child, the illegitimate child’s right is recognized.

LXXI. Illegitimate Child and the Parent’s Legitimate Family Home

If the inherited property is also used as a family home, succession rights still exist, but there may be additional issues involving possession, occupancy, surviving spouse, minor children, and exemption from execution.

The illegitimate child’s ownership share does not always translate into immediate physical possession of a specific room or portion of the house.

Partition or settlement may be necessary.

LXXII. Illegitimate Child’s Right to Possession

Before partition, an heir generally has a co-ownership interest in the estate, not exclusive ownership of a specific portion.

The illegitimate child may not forcibly take possession of a particular part of the property without settlement or agreement.

However, other heirs likewise may not exclude the illegitimate child from the estate or deny the child’s lawful share.

LXXIII. Income From the Parent’s Inherited Property

If the inherited property earns income after the parent’s death, the illegitimate child may be entitled to a proportionate share of net income corresponding to the hereditary share, subject to estate obligations and administration.

If one heir exclusively collects rent, crops, or proceeds, the other heirs may demand accounting.

LXXIV. Improvements Made by Other Heirs

If other heirs made improvements on inherited property after the parent’s death, disputes may arise regarding reimbursement, useful expenses, necessary expenses, and increased value.

The illegitimate child’s ownership share is not automatically lost merely because another heir improved the property.

However, equity and co-ownership rules may affect reimbursement and partition.

LXXV. Partition of Inherited Property

Partition may be done:

extrajudicially, if all heirs agree and legal requirements are met;
judicially, if there is disagreement, incapacity, unknown heirs, contested filiation, or other complications.

An illegitimate child who is an heir must be included.

A partition excluding an heir may be attacked.

LXXVI. Sale Instead of Physical Division

If inherited land cannot be conveniently divided, the heirs may agree to sell it and divide the proceeds according to their shares.

If no agreement exists, judicial partition may determine whether the property should be divided, assigned, or sold.

The illegitimate child is entitled to the value of his or her share, not necessarily to a physically segregated portion.

LXXVII. Rights of Creditors

The illegitimate child’s inheritance is subject to estate debts.

Heirs do not receive property free from the lawful obligations of the estate.

If the parent inherited property but also left debts, the inherited property may be used to satisfy obligations before distribution.

LXXVIII. The Illegitimate Child as Compulsory Heir Cannot Be Ignored

The presence of an illegitimate child changes the computation of the estate.

Legitimate heirs cannot simply divide the estate among themselves and treat the illegitimate child as having no share.

Even where family members object morally, socially, or emotionally, the law gives the illegitimate child hereditary rights.

LXXIX. Practical Computation: Parent Leaves One Legitimate Child and One Illegitimate Child

Estate: ₱9,000,000 Heirs: one legitimate child and one illegitimate child No spouse, no parents.

Ratio:

legitimate child: 2 parts;
illegitimate child: 1 part.

Total: 3 parts.

Distribution:

legitimate child: ₱6,000,000;
illegitimate child: ₱3,000,000.

This applies even if the ₱9,000,000 estate consists entirely of land the parent inherited from the parent’s own father.

LXXX. Practical Computation: Parent Leaves Spouse, One Legitimate Child, and One Illegitimate Child

Estate: ₱12,000,000 Heirs: spouse, one legitimate child, one illegitimate child.

Ratio:

spouse: 1 part;
legitimate child: 1 part;
illegitimate child: 1/2 part.

Total: 2.5 parts.

Distribution:

spouse: ₱4,800,000;
legitimate child: ₱4,800,000;
illegitimate child: ₱2,400,000.

LXXXI. Practical Computation: Parent Leaves Only Three Illegitimate Children

Estate: ₱15,000,000 Heirs: three illegitimate children only.

Distribution:

each illegitimate child receives ₱5,000,000.

When there are no legitimate children, no surviving spouse, and no legitimate ascendants, illegitimate children may inherit the whole estate.

LXXXII. Practical Computation: Parent Leaves Two Legitimate Children and One Illegitimate Child

Estate: ₱10,000,000 Heirs: two legitimate children and one illegitimate child.

Ratio:

legitimate child A: 1;
legitimate child B: 1;
illegitimate child: 1/2.

Total: 2.5.

Distribution:

legitimate child A: ₱4,000,000;
legitimate child B: ₱4,000,000;
illegitimate child: ₱2,000,000.

LXXXIII. The Illegitimate Child’s Share May Be Paid in Value

The law does not always require that the illegitimate child receive a specific parcel inherited by the parent.

The child’s legitime or intestate share may be satisfied by:

land;
cash;
assignment of rights;
proceeds from sale;
other estate property.

What matters is that the child receives the lawful share.

LXXXIV. Can Legitimate Heirs Keep the Inherited Family Land and Pay the Illegitimate Child?

Yes, if the parties agree, or if partition proceedings lawfully result in that arrangement.

For example, legitimate heirs may keep ancestral land inherited by the parent and pay the illegitimate child the value of the child’s share.

However, they cannot unilaterally deprive the illegitimate child of the share without consent or legal proceedings.

LXXXV. Can the Parent’s Family Argue That the Property “Came From Their Side”?

They may argue it morally or emotionally, but legally, once the parent inherited the property and owned it, the property became part of the parent’s estate.

The illegitimate child inherits from the parent.

The fact that the property came from the parent’s legitimate family does not automatically exclude the illegitimate child, unless a special rule applies, such as:

Article 992, if the child is claiming directly from legitimate relatives by intestacy;
reserva troncal;
conditions in a will or donation;
property regime limitations;
invalidity of the parent’s title;
prior sale or transfer by the parent;
estate debts or liens.

LXXXVI. Can the Parent Avoid This by Leaving Everything to Legitimate Children?

Not completely.

The parent may make a will, but the will must respect the legitime of the illegitimate child.

If the will gives everything to legitimate children and nothing to the illegitimate child, the illegitimate child may demand the legitime.

LXXXVII. Can the Parent Sell the Property During Lifetime to Avoid Inheritance?

A parent generally may sell property during lifetime. While alive, the parent owns the property and the future heir has no vested successional right.

But if the sale is simulated, fraudulent, or without real consideration, it may be challenged.

If the transfer is actually a donation disguised as a sale and it impairs legitime, it may be subject to reduction.

LXXXVIII. Can the Parent Donate Everything to Legitimate Children Before Death?

A parent may donate property, but donations cannot impair the legitime of compulsory heirs.

If donations to legitimate children leave nothing for the illegitimate child’s legitime, the illegitimate child may seek reduction of inofficious donations after the parent’s death.

LXXXIX. What If the Illegitimate Child Was Not Recognized During the Parent’s Lifetime?

The child may still have remedies, but timing matters.

Under the Family Code, actions to establish illegitimate filiation are subject to specific rules. If the action is based on certain strong documentary evidence, it may be brought during the lifetime of the child. If based on other evidence, the action generally must be brought during the lifetime of the alleged parent.

This is one of the most important practical issues. A child who cannot prove filiation cannot successfully claim inheritance.

XC. What If the Parent’s Name Appears on the Birth Certificate?

If the parent signed or acknowledged the birth certificate, it may be strong evidence.

If the name was merely supplied by another person without the parent’s participation, it may be insufficient.

The details matter.

XCI. What If the Parent Publicly Treated the Child as His or Hers?

Open and continuous possession of the status of a child may be relevant evidence, depending on the action and timing.

Evidence may include:

school records;
medical records;
family photographs;
letters;
messages;
financial support;
insurance documents;
employment records listing dependents;
testimony of relatives;
public acknowledgment.

However, evidentiary sufficiency depends on the rules governing filiation.

XCII. What If Other Heirs Refuse DNA Testing?

DNA may be relevant in filiation disputes, but refusal, availability of samples, procedural rules, and the nature of the action all matter.

DNA alone does not automatically settle every inheritance issue. The court must still determine legal filiation and the timeliness of the action.

XCIII. Illegitimate Child’s Rights Are Not Based on the Parent’s Marital Fault

The child’s inheritance rights do not depend on whether the parent committed adultery, concubinage, or other marital wrongdoing.

The law does not punish the child for the circumstances of birth.

The child’s rights arise from filiation and succession law.

XCIV. Illegitimate Children of Void Marriages

Children of void marriages may be illegitimate, except in specific cases where the law treats them as legitimate, such as children conceived or born before the judgment of annulment or absolute nullity under certain provisions, and children of marriages covered by specific Family Code rules.

Classification affects inheritance.

One must determine the child’s exact legal status under the Family Code, not merely whether the parents’ relationship was irregular.

XCV. Illegitimate Children of Bigamous or Void Marriages

Children of bigamous or void marriages may have particular status issues. Some may be considered legitimate under specific statutory provisions; others may be illegitimate.

The classification determines whether the child receives a legitimate child’s share or an illegitimate child’s share.

XCVI. Conflict Between Family Expectations and Legal Rights

Many disputes arise because the legitimate family believes inherited ancestral property should stay within the legitimate line.

Philippine law partly accommodates that sentiment through Article 992 and reserva troncal. But it does not erase the illegitimate child’s direct right to inherit from the parent.

Once the parent owns the property, the illegitimate child’s compulsory heirship attaches to the parent’s estate.

XCVII. Summary of Governing Principles

An illegitimate child is a compulsory heir of the parent.
The illegitimate child’s legitime is generally one-half of the legitime of a legitimate child.
The illegitimate child may inherit property that the parent inherited from others.
The source of the parent’s property generally does not matter once it forms part of the parent’s estate.
If the parent survived the original decedent, the parent acquired hereditary rights that may pass to the parent’s heirs.
If the parent died before the original decedent, the illegitimate child may face Article 992 if claiming from the parent’s legitimate relatives by intestacy.
Article 992 does not bar inheritance from the parent.
Article 992 may bar intestate inheritance from the legitimate relatives of the parent.
A will may give property to an illegitimate child, subject to legitime.
The parent cannot deprive the illegitimate child of legitime without valid disinheritance.
Filiation must be legally proven.
Inherited property may be affected by reserva troncal.
Estate debts, taxes, property regime liquidation, and partition affect actual distribution.
Exclusion of an illegitimate child from settlement may be challenged.
The illegitimate child usually inherits an undivided share before partition, not an automatic physical portion of a specific property.

XCVIII. Conclusion

In the Philippine legal context, an illegitimate child has a clear and enforceable right to inherit from his or her parent. That right extends to property that the parent inherited, because once the parent acquired the property, it became part of the parent’s estate.

The major limitation arises when the illegitimate child is not truly claiming from the parent, but from the parent’s legitimate relatives. In that setting, Article 992 of the Civil Code may bar intestate succession. But where the claim is directed against the deceased parent’s own estate, the illegitimate child remains a compulsory heir.

Thus, the decisive questions are:

Did the parent already own or acquire hereditary rights over the property?
Is the illegitimate child claiming from the parent or directly from the parent’s legitimate relatives?
Has filiation been legally established?
Who are the other surviving heirs?
Is there a will?
Are legitimes impaired?
Is the property subject to reserva troncal, prior transfers, debts, or property-regime issues?

When the answer shows that the property formed part of the parent’s estate, the illegitimate child is entitled to inherit according to Philippine succession law.
