I. Introduction

In Philippine succession law, the legitimacy or illegitimacy of a child directly affects the child’s inheritance rights. This becomes especially important when a parent enters into a subsequent marriage that is later found to be void, such as a bigamous marriage, a marriage contracted without a valid marriage license, a psychologically incapacitated marriage under Article 36 of the Family Code, or another marriage void from the beginning under Philippine law.

The central question is this: What inheritance rights do children have when they are born of a subsequent marriage that is void?

The answer depends on several related issues: the nature of the void marriage, whether the child is considered legitimate or illegitimate, whether the parents were capacitated to marry at the time of conception or birth, whether the marriage was void under Article 36, whether there was a prior existing marriage, whether the parent died testate or intestate, and whether compulsory heirs are involved.

Philippine law distinguishes sharply between legitimate children and illegitimate children. Both may inherit, but they do not inherit in the same proportion, and they do not always have the same rights against other heirs.

II. Basic Concepts

A. Legitimate Children

Under the Family Code, legitimate children are generally those conceived or born during a valid marriage of the parents. Legitimate children enjoy full rights of filiation, including the right to use the surnames of the father and mother, receive support, and inherit from their parents and other ascendants.

In succession, legitimate children are compulsory heirs. They are entitled to a legitime, meaning a portion of the estate that the parent cannot freely dispose of by will.

B. Illegitimate Children

Illegitimate children are those conceived and born outside a valid marriage, unless the law classifies them otherwise. They also have rights to support and inheritance, but their inheritance share is generally smaller than that of legitimate children.

Illegitimate children are also compulsory heirs, but their legitime is limited. Under the Civil Code, the legitime of each illegitimate child is generally one-half of the legitime of each legitimate child, subject to the rule that the total legitime of illegitimate children must not impair the legitime of legitimate children.

C. Void Marriage

A void marriage is one that is considered legally inexistent from the beginning. It produces no marital bond, although Philippine law recognizes certain effects for reasons of equity, property relations, legitimacy of certain children, and protection of innocent parties.

Examples of void marriages include:

Bigamous or polygamous marriages, except in certain cases involving presumptive death under the Family Code;
Marriages contracted by a person below the required age;
Marriages solemnized without legal authority, unless one or both parties believed in good faith that the solemnizing officer had authority;
Marriages contracted without a valid marriage license, except those exempt from the license requirement;
Incestuous marriages;
Marriages void by reason of public policy;
Marriages void due to psychological incapacity under Article 36 of the Family Code.

III. The Effect of a Void Subsequent Marriage on Children

A void subsequent marriage usually refers to a later marriage entered into by a person who had a previous existing marriage, or a later marriage that is void for some other legal reason. The inheritance status of the children depends on how the law treats their filiation.

The general rule is:

Children born or conceived of a void marriage are illegitimate.

However, there are important exceptions.

IV. General Rule: Children of Void Marriages Are Illegitimate

Under Philippine law, if a marriage is void from the beginning, children conceived or born of that union are generally considered illegitimate, because there was no valid marriage between the parents.

This rule matters greatly in inheritance. If a child is considered illegitimate, the child may still inherit from the parent, but not in the same amount as a legitimate child.

For example, if a man has legitimate children from a first valid marriage and later enters into a second void marriage, the children of the second union are generally illegitimate. Upon the father’s death, the legitimate children of the first marriage and the illegitimate children of the second union may all inherit from him, but their shares will differ.

V. Important Exceptions: When Children of a Void Marriage May Be Legitimate

Although the general rule is that children of void marriages are illegitimate, the Family Code recognizes specific exceptions.

A. Children of Marriages Void Under Article 36

Children conceived or born before the judgment of annulment or absolute nullity of a marriage under Article 36 has become final are considered legitimate.

Article 36 concerns marriages void because one or both parties were psychologically incapacitated to comply with the essential marital obligations. Although the marriage is void, the law protects the status of children conceived or born before the final judgment declaring the marriage void.

Thus, in an Article 36 case, the child is not automatically illegitimate merely because the marriage is void. If the child was conceived or born before the final judgment, the child is treated as legitimate.

B. Children of Marriages Void Under Article 53

Children of subsequent marriages that are void under Article 53 of the Family Code may also be considered legitimate.

Article 53 concerns a situation where a previous marriage has been annulled or declared void, but the parties fail to comply with certain recording, partition, distribution, and delivery requirements before entering into a subsequent marriage. The subsequent marriage is void for failure to comply with Article 52.

Children of such subsequent marriage are considered legitimate.

This is a crucial exception. Even if the subsequent marriage is void, children born of that marriage may still be legitimate if the voidness arises from noncompliance with Article 52 in relation to Article 53.

VI. Bigamous Subsequent Marriage and Inheritance Rights of Children

A common situation involves a person who contracts a second marriage while the first marriage is still legally existing. This second marriage is generally bigamous and void.

A. Status of the Second Marriage

A bigamous marriage is void from the beginning unless it falls under special rules involving a declaration of presumptive death under the Family Code. If there was no valid termination of the first marriage, and no valid declaration of presumptive death, the second marriage has no legal effect as a marriage.

B. Status of Children of the Bigamous Marriage

Children born of a bigamous marriage are generally considered illegitimate, unless they fall under a recognized statutory exception.

This means that, for inheritance purposes, they inherit as illegitimate children of the common parent.

C. Inheritance from the Common Parent

The illegitimate child may inherit from the parent who recognized the child or whose filiation has been legally established. If the child’s filiation to the deceased parent is proven, the child is a compulsory heir.

The child’s legitime is generally one-half of the legitime of a legitimate child.

D. Inheritance from the Other Parent

The child may also inherit from the other biological parent, again as an illegitimate child unless the child has legitimate status under some other legal basis.

E. No Inheritance from the Legitimate Relatives of the Parent by Intestate Succession

One of the harshest rules in Philippine succession law is the barrier between legitimate and illegitimate families.

Illegitimate children generally do not inherit by intestate succession from the legitimate children and relatives of their parent. Conversely, legitimate children and relatives generally do not inherit intestate from the illegitimate child.

This is sometimes referred to as the rule under Article 992 of the Civil Code, which creates a legal barrier between the legitimate family and the illegitimate family in intestate succession.

Thus, an illegitimate child of a void second marriage may inherit from the biological parent, but generally not from the legitimate grandparents, legitimate siblings, or other legitimate relatives of that parent by intestacy.

VII. The Concept of Legitime

To understand the inheritance rights of children, one must understand the concept of legitime.

Legitime is the part of the testator’s property that the law reserves for compulsory heirs. A parent cannot freely deprive compulsory heirs of their legitime except for valid causes of disinheritance provided by law.

Children, whether legitimate or illegitimate, are compulsory heirs. However, they receive different shares.

VIII. Legitimate Children as Compulsory Heirs

Legitimate children and descendants have the strongest inheritance rights. They exclude many other heirs and receive the largest legitime.

When a parent dies leaving legitimate children, the legitimate children are entitled to a legitime equal to one-half of the hereditary estate, divided equally among them.

The remaining half of the estate is the free portion, unless other compulsory heirs such as a surviving spouse or illegitimate children are also present. The shares of those heirs may be charged against the free portion or otherwise computed according to the Civil Code rules on legitime.

IX. Illegitimate Children as Compulsory Heirs

Illegitimate children are compulsory heirs, but their legitime is smaller.

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

However, the legitime of illegitimate children must not impair the legitime of legitimate children. If the estate is insufficient, the law protects the legitime of legitimate children first.

X. Sample Computations

A. Parent Dies Leaving Legitimate Children and Illegitimate Children

Suppose a father dies leaving:

Two legitimate children from his first valid marriage; and
Two illegitimate children from a void subsequent marriage;
No surviving spouse;
An estate worth ₱12,000,000.

The legitimate children are entitled to one-half of the estate as legitime.

Total legitime of legitimate children: ₱6,000,000 Each legitimate child: ₱3,000,000

Each illegitimate child is entitled to one-half of the legitime of each legitimate child.

Each illegitimate child: ₱1,500,000 Total for two illegitimate children: ₱3,000,000

The remaining amount is the free portion.

Estate: ₱12,000,000 Legitimate children’s legitime: ₱6,000,000 Illegitimate children’s legitime: ₱3,000,000 Free portion: ₱3,000,000

If there is no will, intestate succession rules may allocate the estate in a way that gives the children their legal shares, subject to the relevant rules.

B. Parent Dies Leaving Only Illegitimate Children

Suppose a parent dies leaving only illegitimate children and no legitimate children, no surviving spouse, and no legitimate descendants.

In that case, the illegitimate children may inherit from the parent. Their share depends on the presence or absence of other heirs, such as surviving parents or a surviving spouse.

If only illegitimate children survive, they may inherit the estate by intestate succession.

C. Parent Dies Leaving Legitimate Children, Illegitimate Children, and Surviving Spouse

Suppose the deceased leaves:

Two legitimate children;
One illegitimate child from a void subsequent marriage;
A surviving legal spouse;
An estate of ₱12,000,000.

The legitimate children receive their legitime. The surviving spouse also receives a legitime generally equivalent to the share of one legitimate child when concurring with legitimate children. The illegitimate child receives one-half of the share of a legitimate child, subject to the rules on impairment of legitime.

The computation may be more complex because the shares of the surviving spouse and illegitimate children must be reconciled with the legitime of legitimate children and the available free portion.

XI. Testate Succession: When There Is a Will

A parent may execute a will, but the will cannot impair the legitime of compulsory heirs.

A. Legitimate Children

Legitimate children cannot be deprived of their legitime except by valid disinheritance for a cause provided by law. If a will gives away property in a way that impairs the legitime of legitimate children, the testamentary dispositions may be reduced.

B. Illegitimate Children

Illegitimate children also cannot be deprived of their legitime except by valid disinheritance. However, their legitime is smaller than that of legitimate children.

C. Children of the Void Subsequent Marriage

If the children of the void subsequent marriage are illegitimate, their legitime is that of illegitimate children. If they fall under the exceptions for legitimacy, such as children covered by Article 36 or Article 53, they inherit as legitimate children.

XII. Intestate Succession: When There Is No Will

When the parent dies without a will, the estate is distributed according to the Civil Code rules on intestate succession.

A. Legitimate Children Alone

If only legitimate children survive, they inherit the entire estate in equal shares.

B. Legitimate Children and Illegitimate Children

If legitimate and illegitimate children survive, both inherit from the deceased parent, but illegitimate children receive a smaller share.

Generally, each illegitimate child receives one-half of the share of a legitimate child.

C. Illegitimate Children Alone

If only illegitimate children survive, they may inherit the estate, subject to the rights of other compulsory heirs such as a surviving spouse or surviving parents, if any.

D. Surviving Spouse and Children

The surviving spouse’s share depends on whom the spouse concurs with. The legal spouse is the spouse from a valid marriage, not from a void marriage. A person who was merely a party to a void marriage generally does not inherit as a surviving spouse, because there was no valid marital bond.

XIII. Does the Putative Spouse in the Void Subsequent Marriage Inherit?

Generally, a party to a void marriage does not inherit as a legal spouse because the marriage is inexistent from the beginning.

This is especially important in a bigamous marriage. The second spouse in a void bigamous marriage is generally not a surviving spouse for purposes of succession. The lawful surviving spouse is the spouse in the valid existing marriage.

However, property relations and equitable remedies may still arise depending on good faith, co-ownership, actual contributions, and the applicable Family Code provisions. These property issues are distinct from succession rights as a spouse.

The children’s inheritance rights are not the same as the putative spouse’s rights. Even if the second spouse does not inherit as a spouse, the children may still inherit from their biological parent if filiation is established.

XIV. Filiation: The Key to Inheritance

A child cannot inherit from a parent unless filiation is established.

A. Legitimate Filiation

Legitimate filiation may be established by:

The record of birth appearing in the civil register;
An admission of legitimate filiation in a public document or private handwritten instrument signed by the parent;
Other means allowed by the Rules of Court and special laws.

B. Illegitimate Filiation

Illegitimate filiation may likewise be established through the record of birth, admission in a public document, admission in a private handwritten instrument, or other evidence allowed by law.

For illegitimate children, proof of filiation is often heavily litigated, especially when the deceased parent’s legitimate family contests the claim.

C. Importance of the Birth Certificate

A birth certificate naming the parent may be important evidence, but its legal effect depends on whether the parent signed it or otherwise acknowledged the child. A mere entry of the father’s name, without the father’s participation or acknowledgment, may not always be sufficient.

D. Action to Claim Filiation

The period for bringing an action to claim filiation depends on whether the child is legitimate or illegitimate and on the type of evidence relied upon.

For illegitimate children, if the action is based on open and continuous possession of status or other evidence, the law imposes stricter time limits. If based on a record of birth, public document, or private handwritten instrument signed by the parent, the right may be asserted during the lifetime of the child.

XV. Rights of Children Born of a Void Subsequent Marriage

Children born of a void subsequent marriage may have the following rights against their biological parent:

The right to establish filiation;
The right to use the surname of the father under conditions allowed by law;
The right to support;
The right to inherit as compulsory heirs;
The right to question transactions that impair their legitime;
The right to participate in settlement proceedings;
The right to receive notices in estate proceedings if their status as heirs is recognized or asserted;
The right to demand partition after the estate is settled;
The right to seek reduction of inofficious donations or testamentary dispositions that impair legitime.

Their classification as legitimate or illegitimate determines the size and scope of these rights.

XVI. Children of a Void Subsequent Marriage Under Article 36

Article 36 cases deserve special attention.

A marriage declared void under Article 36 is void from the beginning. However, the Family Code expressly protects children conceived or born before the judgment of nullity becomes final by treating them as legitimate.

This means that, for inheritance purposes, such children inherit as legitimate children.

Example

A man and woman marry. Later, the marriage is declared void under Article 36 because one party was psychologically incapacitated. Their child was born before the judgment became final.

That child is legitimate.

If either parent dies, the child inherits as a legitimate child, not as an illegitimate child.

This rule applies even though the marriage itself was void from the beginning.

XVII. Children of a Void Subsequent Marriage Under Article 53

Article 53 applies where a prior marriage was annulled or declared void, but the required liquidation, partition, distribution, and recording under Article 52 were not properly completed before a subsequent marriage was contracted.

The subsequent marriage is void. Nevertheless, children of that subsequent marriage are considered legitimate.

This rule protects children from the legal consequences of their parents’ failure to comply with post-annulment or post-nullity formalities.

XVIII. Children of a Bigamous Void Marriage Compared with Children of Article 36 and Article 53 Marriages

The distinction is critical.

Children of a bigamous void marriage are generally illegitimate.

Children of a marriage void under Article 36, if conceived or born before final judgment, are legitimate.

Children of a subsequent marriage void under Article 53 are legitimate.

Thus, not every void marriage produces the same effect on children.

The reason is statutory. Philippine law specifically grants legitimate status in certain void marriage situations but not in all.

XIX. Inheritance from the Father and Mother

A child’s inheritance rights must be analyzed separately as to each parent.

A child may be illegitimate as to both parents if the parents were not validly married. However, the child may still inherit from both biological parents once filiation is established.

Where the mother is unmarried or in a void marriage, maternity is usually easier to prove through the birth record. Paternity may require acknowledgment or other evidence.

XX. The Legal Spouse Versus the Void Subsequent Spouse

In a void subsequent marriage, the person from the subsequent marriage is generally not the legal surviving spouse.

For example:

A man marries Wife A. Without annulment, declaration of nullity, or death of Wife A, he marries Wife B. The second marriage is void. He has children with Wife B.

Upon his death:

Wife A may inherit as the legal surviving spouse;
Wife B generally does not inherit as a spouse;
The children with Wife B may inherit, but generally as illegitimate children;
The legitimate children with Wife A inherit as legitimate children.

This often creates conflict in estate settlement proceedings.

XXI. Property Relations in a Void Subsequent Marriage

Although a void spouse generally does not inherit as a spouse, property relations may still exist.

Depending on the circumstances, the property regime may be governed by rules on co-ownership, especially where both parties contributed to the acquisition of property.

If both parties acted in good faith in a void marriage, certain property rules may apply under the Family Code. If one party was in bad faith, that party may forfeit certain shares in favor of common children or other legally preferred persons.

However, these are property liquidation rules, not inheritance rights as a surviving spouse.

The children’s rights may be affected because the estate of the deceased parent consists only of the property that actually belonged to that parent after liquidation of property relations.

XXII. Estate Settlement Issues

When a parent dies leaving children from a valid marriage and children from a void subsequent marriage, estate settlement may involve several disputes.

A. Determination of Heirs

The court may need to determine who the heirs are, including whether the children of the void marriage are legitimate or illegitimate.

B. Proof of Filiation

The children of the void subsequent marriage may need to prove filiation, especially if the legitimate family contests their status.

C. Validity of the Subsequent Marriage

The status of the subsequent marriage may be relevant, though the children may still claim inheritance from the biological parent even if the marriage is void.

D. Liquidation of Property Relations

Before distributing the estate, the property relations of the deceased must be liquidated. This may include the property regime of the valid marriage, any co-owned properties with the void spouse, and separate properties.

E. Collation

Donations or advances made by the deceased to compulsory heirs may need to be brought into collation, depending on the circumstances.

F. Reduction of Inofficious Donations

If the deceased donated too much property during lifetime and impaired the legitime of compulsory heirs, the heirs may seek reduction of inofficious donations.

XXIII. Article 992 and the Barrier Between Legitimate and Illegitimate Families

Article 992 of the Civil Code is one of the most important provisions affecting illegitimate children.

It provides, in substance, that an illegitimate child has no right to inherit ab intestato from the legitimate children and relatives of the father or mother, and legitimate children and relatives have no right to inherit in the same manner from the illegitimate child.

This rule does not prevent the illegitimate child from inheriting from the biological parent. It prevents intestate succession between the illegitimate child and the legitimate relatives of that parent.

Example

A father has a legitimate son from a valid first marriage and an illegitimate daughter from a void second marriage.

The illegitimate daughter may inherit from the father.

But if the legitimate son later dies without a will, the illegitimate daughter generally cannot inherit from the legitimate son by intestate succession merely because they share the same father.

Similarly, the legitimate relatives of the father generally cannot inherit intestate from the illegitimate child.

XXIV. Can Illegitimate Children Inherit by Will from Legitimate Relatives?

Yes, the Article 992 barrier applies to intestate succession, not necessarily to testamentary succession.

A legitimate relative may give property to an illegitimate child by will, provided the legitime of compulsory heirs is not impaired and the devise or legacy is not otherwise prohibited by law.

Thus, while an illegitimate child may be barred from inheriting intestate from legitimate relatives, that child may still receive property through a valid will or donation, subject to legal limitations.

XXV. Representation and Illegitimate Children

Representation allows a person to inherit in place of another who cannot inherit due to predecease, incapacity, or disinheritance.

In the legitimate line, representation is recognized in the direct descending line. However, because of the barrier between legitimate and illegitimate families, representation issues can become complex where illegitimate children attempt to represent a parent in the estate of legitimate relatives.

Generally, an illegitimate child cannot represent the illegitimate parent in inheriting from the legitimate relatives of that parent if Article 992 applies.

XXVI. Adoption and Inheritance

Adoption changes inheritance rights. A legally adopted child generally becomes a legitimate child of the adopter for civil purposes and acquires inheritance rights from the adopter.

However, adoption does not necessarily erase all issues concerning biological filiation for purposes of inheritance from biological parents, depending on the applicable law and circumstances.

If a child born of a void subsequent marriage is adopted by another person, the child’s inheritance rights must be analyzed under adoption law as well as succession law.

XXVII. Effect of Recognition or Acknowledgment

Recognition or acknowledgment is essential for many illegitimate children to claim rights.

A father may recognize an illegitimate child through:

Signing the birth certificate;
Executing an affidavit of acknowledgment;
Referring to the child as his own in a public document;
Writing and signing a private handwritten instrument acknowledging the child;
Other acts or evidence allowed by law.

Recognition affects support, surname, and inheritance.

Without proof of filiation, the child may be excluded from inheritance proceedings, even if biologically related.

XXVIII. Use of Surname and Inheritance

The right of an illegitimate child to use the father’s surname does not automatically determine inheritance rights. It may be evidence of acknowledgment, but inheritance still depends on legally established filiation.

Conversely, a child may be entitled to inherit even if the child did not use the father’s surname, provided filiation is proven by competent evidence.

XXIX. DNA Evidence

DNA evidence may be relevant in proving biological relationship. Philippine courts have recognized DNA testing as a valuable tool in paternity and filiation cases, subject to procedural rules and evidentiary standards.

However, DNA evidence alone may not always resolve legal filiation questions, especially where the law imposes specific periods or modes for establishing filiation. It is strongest when used together with other evidence, such as documents, acknowledgment, support, photographs, communications, and testimony.

XXX. Void Marriage Versus Voidable Marriage

A void marriage is different from a voidable marriage.

A voidable marriage is valid until annulled. Children conceived or born before the decree of annulment are generally legitimate.

In a void marriage, the marriage is inexistent from the beginning, and children are generally illegitimate unless the law provides otherwise.

Thus, the distinction between void and voidable marriages is critical in inheritance disputes.

XXXI. Practical Scenarios

Scenario 1: Second Marriage During Existing First Marriage

A man marries Woman A. While that marriage is still valid, he marries Woman B and has children with her.

The marriage to Woman B is void for being bigamous. The children with Woman B are generally illegitimate. They may inherit from the father as illegitimate children if filiation is established. Woman B does not inherit as a surviving spouse.

Scenario 2: Article 36 Marriage

A man and woman marry. The marriage is later declared void due to psychological incapacity. Their children were born before the judgment became final.

The children are legitimate. They inherit from both parents as legitimate children.

Scenario 3: Failure to Comply with Article 52 Before Remarriage

A prior marriage is declared void. The party remarries without complying with the required recording and liquidation requirements under Article 52. The subsequent marriage is void under Article 53.

Children of the subsequent marriage are legitimate.

Scenario 4: No Marriage License

A couple marries without a valid marriage license and has children.

The marriage may be void. Unless another legal rule applies, the children are generally illegitimate. They may inherit from both parents as illegitimate children if filiation is established.

Scenario 5: Putative Second Spouse Claims Inheritance

A woman enters into a marriage with a man who secretly had an existing valid marriage. The man dies.

Even if the woman acted in good faith, she generally does not inherit as a legal spouse because the marriage was void. However, she may have property claims depending on contribution and applicable property rules. Their children may inherit from the father as illegitimate children unless a statutory exception applies.

XXXII. The Role of Good Faith

Good faith may affect property relations between parties to a void marriage, but it does not automatically make the marriage valid.

Good faith may protect the innocent party in certain property consequences. It may also affect forfeiture rules. However, good faith of the parents generally does not convert children of a void marriage into legitimate children unless the Family Code expressly provides that result.

Thus, even if both parties believed the subsequent marriage was valid, the children may still be illegitimate if the marriage is void and no statutory exception applies.

XXXIII. Rights Against the Estate

Children born of a void subsequent marriage should protect their rights in the estate by:

Establishing filiation;
Participating in estate settlement proceedings;
Opposing exclusion from the list of heirs;
Seeking inventory of estate assets;
Questioning simulated transfers;
Seeking collation of donations where proper;
Seeking reduction of inofficious donations;
Demanding partition;
Asserting legitime as compulsory heirs.

The classification of the child determines the amount, but filiation determines whether the child can claim at all.

XXXIV. Disinheritance

A parent cannot simply exclude a compulsory heir by silence or preference.

A child, whether legitimate or illegitimate, may be deprived of legitime only by valid disinheritance in a will and only for causes expressly provided by law.

If a parent makes a will leaving everything to the legitimate family and nothing to an acknowledged illegitimate child, the illegitimate child may question the will to the extent that the legitime is impaired.

XXXV. Donations During Lifetime

Some parents attempt to avoid inheritance disputes by transferring property during lifetime to selected heirs. However, donations that impair the legitime of compulsory heirs may be reduced.

Both legitimate and illegitimate children may challenge excessive donations if their legitime is prejudiced.

In estate settlement, donations to compulsory heirs may also be subject to collation, depending on whether they are considered advances on inheritance.

XXXVI. Settlement Outside Court

Families may settle estates extrajudicially if legal requirements are met. However, all heirs must be included. Excluding an illegitimate child who is a compulsory heir may expose the settlement to challenge.

If children of a void subsequent marriage are known and their filiation is established, they should not be ignored in extrajudicial settlement.

XXXVII. Prescription and Laches

Inheritance claims may be affected by prescription, laches, and procedural rules. A child who delays asserting filiation or inheritance rights may face legal obstacles.

The most urgent issue is often the action to establish filiation. Once filiation is established, inheritance rights can be asserted in estate proceedings, subject to the rules on settlement, partition, and prescription.

XXXVIII. Important Distinctions

A. Status of the Marriage Is Not Always the Same as Status of the Child

A marriage may be void, but the law may still treat the child as legitimate in specific cases, especially Article 36 and Article 53 situations.

B. Status of the Child Determines Share

Legitimate children receive a larger inheritance share than illegitimate children.

C. Filiation Must Be Proven

Even an illegitimate child has inheritance rights only if filiation is legally established.

D. The Void Spouse and the Children Have Different Rights

The party to the void subsequent marriage may not inherit as a spouse, but the children may inherit from the biological parent.

E. Article 992 Limits Inheritance from Legitimate Relatives

An illegitimate child may inherit from the parent but is generally barred from intestate succession involving the parent’s legitimate relatives.

XXXIX. Constitutional and Policy Considerations

Philippine law protects the family as a basic social institution, but it also recognizes the rights of children regardless of the circumstances of their birth. The law grants illegitimate children rights to support and inheritance, though not equal to those of legitimate children.

The distinction between legitimate and illegitimate children remains significant in succession law. While modern legal policy increasingly protects children from discrimination, the Civil Code and Family Code still maintain different inheritance shares.

The law attempts to balance several interests:

Protection of the legitimate family;
Recognition of biological parent-child relationships;
Protection of compulsory heirs;
Stability of marriage;
Prevention of fraud in succession;
Protection of innocent children from the legal consequences of their parents’ acts.

XL. Summary of Rules

The following rules summarize the topic:

Children of a valid marriage are legitimate.
Children of a void marriage are generally illegitimate.
Children conceived or born before the final judgment in an Article 36 nullity case are legitimate.
Children of a subsequent marriage void under Article 53 are legitimate.
Children of a bigamous void marriage are generally illegitimate.
Legitimate children are compulsory heirs.
Illegitimate children are also compulsory heirs, but their legitime is generally one-half of that of legitimate children.
Illegitimate children may inherit from their biological parent if filiation is established.
Illegitimate children generally cannot inherit intestate from the legitimate relatives of their parent because of Article 992.
The party to a void subsequent marriage generally does not inherit as a surviving spouse.
Good faith may affect property relations but does not automatically create a valid marriage or legitimate status for children.
Filiation is essential to inheritance.
A will cannot impair the legitime of compulsory heirs.
Excessive donations may be reduced if they impair legitime.
Estate settlements that exclude compulsory heirs may be challenged.

XLI. Conclusion

In the Philippines, the inheritance rights of children born of a void subsequent marriage depend primarily on their legal status as legitimate or illegitimate children. The general rule is that children of void marriages are illegitimate, but the Family Code creates important exceptions, especially for children covered by Article 36 and Article 53.

A child born of a void subsequent marriage is not without rights. Even if classified as illegitimate, the child may inherit from the biological parent as a compulsory heir once filiation is established. The child’s share, however, is generally smaller than that of a legitimate child, and the child is subject to the Civil Code barrier against intestate succession between legitimate and illegitimate family lines.

The void spouse and the children must also be distinguished. The spouse in the void subsequent marriage generally does not inherit as a legal spouse, but the children may still inherit from the deceased parent. In estate proceedings, the main issues are usually the validity of the marriage, the classification of the children, proof of filiation, liquidation of property relations, computation of legitime, and protection of compulsory heirs.

Philippine succession law therefore requires careful analysis of both family law and inheritance law. A void subsequent marriage may be legally inexistent, but the children born from that relationship remain protected by law to the extent provided by their filiation and legal status.
