Quick answer

Yes. A great-grandchild may inherit from a great-grandparent by right of representation when the law allows the great-grandchild to step into the place of a nearer descendant who could not inherit—for example, because that nearer descendant died before the great-grandparent.

Representation is not automatic merely because someone is a great-grandchild. The family line, order of deaths, existence and validity of a will, proof of filiation, other surviving heirs, and any disinheritance, unworthiness, adoption, or renunciation must be examined.

The controlling rule is that representation operates without a fixed generational limit in the direct descending line. The representatives divide only the share that the person represented would have received; they do not each receive a full child’s share.

What “inheritance by representation” means

Under Articles 970 and 971 of the Civil Code, representation is a legal mechanism that raises a descendant to the place and degree of the person represented. The representative inherits directly from the deceased owner of the estate—not through the estate of the represented person.

Suppose Lola Maria had two children:

Ana, who is alive; and
Ben, who died before Lola Maria.

If Ben left a daughter, Carla, Carla may represent Ben and receive the share Ben would have received.

If Carla also died before Lola Maria and left two children, Diego and Elena, those great-grandchildren may represent through Ben’s branch. Together, Diego and Elena receive only the portion allocated to that branch.

This is called division per stirpes, or by family branch.

When great-grandchildren may represent a nearer descendant

A great-grandchild may inherit by representation when all applicable requirements are met:

The claimed line runs directly downward from the decedent: great-grandparent, child, grandchild, then great-grandchild.
The person or branch being represented would have been entitled to inherit.
A legally recognized ground for representation exists.
The great-grandchild is legally capable of succeeding.
The relationship or filiation connecting every generation is sufficiently established.

Representation commonly applies when the nearer descendant:

died before the decedent;
was legally incapable or unworthy of inheriting, where the Civil Code permits representation; or
was validly disinherited, in which case that person’s children and descendants preserve the rights of compulsory heirs with respect to the legitime under Article 923.

The actual result remains sensitive to the wording of any will and to the combination of surviving compulsory heirs.

No fixed generational limit in the direct descending line

Article 972 provides that representation takes place in the direct descending line, but never in the ascending line. Article 982 further refers to “grandchildren and other descendants.”

Accordingly, representation may extend beyond grandchildren to great-grandchildren and more remote direct descendants. The important question is not simply the number of generations. It is whether the claimant belongs to the proper descending branch and may legally occupy the place of the person represented.

This broader rule does not apply in the same way to collateral relatives. In the collateral line, representation is limited to children of the decedent’s brothers or sisters. A great-nephew or great-niece ordinarily cannot keep extending representation down a collateral branch.

Great-grandchildren do not normally compete with a living nearer descendant

The nearer degree generally excludes the more remote degree.

If the decedent’s child in a particular branch is alive and qualified to inherit, that child normally inherits in his or her own right. The child’s grandchildren—the decedent’s great-grandchildren—do not also take a separate share from the same branch by representation.

Similarly, if the decedent’s child has died but that child’s own child is alive and qualified, the living grandchild ordinarily represents the deceased child. The grandchild’s children do not simultaneously share that represented portion merely because they are also descendants of the decedent.

Representation becomes relevant to the more remote descendants when the intervening person cannot inherit under circumstances recognized by law.

The share is calculated by branch, not by head

Article 974 requires a per stirpes division. Representatives collectively receive no more than the person represented would have received.

Example

Assume a widowed great-grandparent dies intestate with a net hereditary estate of ₱6 million and two family branches:

Child A is alive.
Child B died earlier.
B’s only child, Grandchild C, also died earlier.
C left Great-grandchildren D and E.

Subject to confirmation that there are no other heirs or legal adjustments:

Child A receives ₱3 million in his or her own right.
B’s branch receives ₱3 million.
D and E divide B’s branch equally, receiving ₱1.5 million each.

D and E do not each receive ₱3 million. They divide the single share that would have belonged to their branch.

If a surviving spouse, nonmarital children or descendants, other compulsory heirs, debts, donations subject to collation, or a valid will are involved, the computation may be different.

Renunciation is an important exception

Representation should not be confused with a voluntary waiver.

Article 977 states that heirs who repudiate their share may not be represented. If a nearer heir survives the decedent but formally renounces the inheritance, that heir’s children do not automatically step into the renounced share by representation.

Article 969 likewise provides that when the nearest relative or all relatives of the nearest degree repudiate, relatives in the following degree inherit in their own right, not by representing those who renounced.

This differs from Article 976: a person may represent someone whose inheritance from a different decedent the representative previously renounced. The precise estates and succession events must therefore be kept separate.

Do not sign a waiver, deed of extrajudicial settlement, quitclaim, or deed of sale without understanding whether it is an acceptance, repudiation, partition, or transfer of an already inherited share. Those acts can have very different legal and tax consequences.

What changes when there is a will

A will must first be proved and allowed in probate before its provisions can be given effect.

A great-grandchild may receive property under a will because:

the testator directly named the great-grandchild as an heir, devisee, or legatee;
the will validly designated a substitute for an originally instituted heir; or
representation operates to preserve a compulsory heir’s rights in a situation recognized by the Civil Code.

A direct gift under a will is not necessarily inheritance “by representation.” It may simply be a testamentary disposition.

The will cannot freely defeat the legitime, or reserved share, of compulsory heirs. Articles 886, 887, and 904–907 protect compulsory heirs and permit reduction of testamentary dispositions that impair their legitimes. A great-grandchild’s status as a compulsory heir generally depends on whether a nearer descendant in the same line is alive and entitled to inherit.

The exact text of the will, the identity of all compulsory heirs, and the net hereditary estate must be reviewed before assigning percentages.

Marital and nonmarital descendants

The Civil Code still uses the statutory term “illegitimate.” In people-first language, “nonmarital child” means a child conceived and born outside a valid marriage, subject to the Family Code’s specific exceptions.

In Aquino v. Aquino, G.R. Nos. 208912 and 209018, December 7, 2021, the Supreme Court en banc adopted a construction of Article 992 under which children, regardless of the circumstances of their birth, may inherit from their direct ascendants, such as grandparents, by representation. The Court expressly recognized both marital and nonmarital children as blood relatives of their parents and direct ascendants for this purpose.

This is important where a great-grandchild’s line includes a nonmarital parent or grandparent. Birth status alone should not be treated as an automatic barrier to representation from a direct ascendant.

However:

filiation must still be legally established;
the applicable shares may differ under the Civil Code;
the claimant must still satisfy all other requirements for representation; and
Aquino’s construction concerns inheritance from direct ascendants and should not be casually extended to unrelated collateral situations.

Adoption requires separate analysis

An adopted child generally has successional rights in relation to the adopter under the governing adoption law. But representation in the estate of the adopter’s own parents or more remote relatives can raise a separate question because the legal relationship created by adoption does not necessarily operate exactly like a blood relationship throughout the extended family.

In Sayson v. Court of Appeals, G.R. Nos. 89224–25, January 23, 1992, the Supreme Court held that adopted children of a predeceased child could not represent that adoptive parent in the intestate estate of the adoptive parent’s parents. The Court distinguished their position from that of a biological child who could represent the deceased parent.

Because Philippine adoption law has since been revised, an adoption-related claim should be evaluated using:

the adoption decree or administrative order;
the date and law governing the adoption;
the precise relationship to the decedent;
the Civil Code and current adoption statute; and
applicable Supreme Court precedent.

Do not assume that an adopted person can—or cannot—represent a parent in a more remote ancestor’s estate without reviewing those documents.

Proof that should be collected and preserved

Representation depends on an unbroken, legally provable family line. Preserve certified copies of:

the decedent’s death certificate;
death certificates of every predeceased child or grandchild in the relevant branch;
certificates of live birth connecting each generation;
marriage certificates where relevant to civil status or property relations;
documents establishing filiation;
adoption decrees or administrative adoption orders;
the original will, codicils, and any probate records;
titles, tax declarations, bank records, stock certificates, business records, and other proof of estate assets;
loan documents and proof of estate debts;
deeds of donation that may affect collation or legitimes;
any deed of extrajudicial settlement, waiver, partition, sale, or self-adjudication;
court decisions involving disinheritance, unworthiness, filiation, marriage validity, or adoption; and
communications showing when an omitted heir learned of a settlement or transfer.

Use Philippine Statistics Authority copies and certified civil-registry records when available. Conflicting spellings, dates, parent entries, delayed registrations, or missing records should be addressed before property is transferred.

Practical steps for a great-grandchild claiming a share

1. Draw the family tree as of the date of death

List the decedent’s spouse, children, grandchildren, and great-grandchildren. Record who was alive when the decedent died and identify the date of death of every predeceased relative.

Inheritance rights transmit from the moment of death, so the sequence of deaths matters.

2. Determine whether there is a will

Search the decedent’s records and ask close relatives or the lawyer who prepared the estate plan. If there is a will, it must go through probate. Do not proceed as though the estate were intestate merely because the family dislikes or disputes the will.

3. Identify the person being represented

A claimant should be able to state clearly:

“I claim through my parent, who would have represented my grandparent, who was a child of the decedent.”

Then verify why each nearer person is unavailable or legally unable to inherit. Death before the decedent, valid disinheritance, unworthiness, and renunciation do not produce identical consequences.

4. Calculate the branch before dividing among representatives

First determine what the original child’s branch would receive. Only then divide that branch among the qualified representatives at the next levels.

5. Inventory property and liabilities

Inheritance shares are computed from the estate after resolving ownership, the surviving spouse’s share in community or conjugal property, debts, expenses, taxes, and other lawful deductions. A land title in the decedent’s name does not always mean the entire property belongs exclusively to the estate.

6. Choose the proper settlement procedure

Under Rule 74, an extrajudicial settlement may generally be used when:

the decedent left no will;
the estate has no outstanding debts;
all heirs participate;
all heirs are of age, or minors are represented by duly authorized judicial or legal representatives; and
the settlement is made in a public instrument and the required publication is completed.

The fact of the extrajudicial settlement must be published in a newspaper of general circulation once a week for three consecutive weeks. Publication does not cure the exclusion of an heir: Rule 74 expressly states that an extrajudicial settlement is not binding on a person who did not participate or had no notice.

If there is a will, disagreement over heirs or shares, unresolved debt, contested filiation, concealed property, incapacity, or an omitted heir, judicial settlement, probate, administration, or an ordinary partition action may be necessary.

7. Attend to estate tax and transfer requirements

For deaths covered by the TRAIN amendments, the estate tax return is generally due within one year from death. In meritorious cases, the Commissioner of Internal Revenue may grant an extension to file of up to 30 days. Payment is generally due when the return is filed, although the Tax Code provides possible extensions for payment subject to statutory conditions.

An estate tax return showing a gross estate exceeding ₱5 million must be supported by the required statement certified by a certified public accountant. A return may also be required even below that amount when the estate includes registered or registrable property for which the BIR must issue a clearance authorizing transfer.

The special estate-tax-amnesty filing period ended on June 14, 2025. Older unsettled estates should now be assessed under the rules applicable to the date of death and current BIR procedures; do not assume that amnesty remains available.

Consult the BIR office handling the decedent’s estate for the current documentary checklist and process for obtaining the electronic Certificate Authorizing Registration, or eCAR.

Common mistakes

Dividing the estate equally among every living descendant without first grouping them by branch.
Assuming all great-grandchildren automatically inherit.
Allowing a living parent or grandparent to inherit while also giving that person’s descendants a separate representative share.
Treating renunciation as though it were predecease.
Ignoring the surviving spouse’s property and inheritance rights.
Using the gross value of land as the estate available for distribution without deducting debts or separating community or conjugal property.
Relying on an unsigned family tree instead of civil-registry evidence.
Excluding a nonmarital descendant solely because of birth status despite Aquino v. Aquino.
Assuming publication validates an extrajudicial settlement that omitted an heir.
Selling the entire inherited property when the seller owns only an undivided hereditary share.
Signing a quitclaim or deed of sale written in legal language the heir does not fully understand.
Delaying estate-tax work because the family has not yet agreed on a physical partition.
Treating an unprobated will as either automatically valid or automatically irrelevant.

When legal help is urgent

Consult a Philippine succession lawyer promptly when:

a deed of extrajudicial settlement has already omitted a branch of descendants;
estate property is being sold, mortgaged, subdivided, or transferred without your consent;
someone asks you to sign a waiver, quitclaim, special power of attorney, or deed of sale;
the estate includes minors, persons under guardianship, or heirs abroad;
there is a disputed or missing birth record;
adoption affects the claimed family line;
a will is hidden, destroyed, contested, or about to be submitted for probate;
property or bank accounts are being concealed or withdrawn;
there are conflicting marriages or disputes over filiation;
the estate has substantial debts or unpaid taxes;
the estate-tax deadline is near or has passed; or
a court, BIR, Registry of Deeds, bank, or another heir has issued a deadline or formal demand.

The two-year period mentioned in Rule 74 concerns specified remedies and liabilities arising from a summary settlement; it should not be treated as a universal deadline for every omitted-heir, fraud, ownership, reconveyance, or partition claim. Different causes of action may have different limitation rules, and questions of possession, fraud, notice, registration, and trust can affect the analysis.

Frequently asked questions

Can great-grandchildren inherit if their parent is alive?

Usually not by representation through that living and qualified parent. A nearer descendant normally excludes more remote descendants in the same branch. A great-grandchild may still receive property if validly named in a will or through another independent legal basis.

Can a great-grandchild inherit when both the decedent’s child and grandchild died first?

Yes, potentially. Representation may continue down the direct descending line. The great-grandchild receives only the portion attributable to that family branch.

Do all great-grandchildren receive equal shares?

Not necessarily. Equality is applied within the appropriate branch. Great-grandchildren from different branches may receive different amounts because each branch first receives the share of the person represented.

What if the grandchild died after the great-grandparent?

That is generally not the same as representation. The grandchild’s hereditary rights may already have vested when the great-grandparent died and may then pass through the grandchild’s own estate. The two estates must be settled separately.

What if the nearer heir waived the inheritance?

The nearer heir’s descendants generally cannot represent an heir who repudiated the share. Depending on who renounced and who else survives, the next degree may inherit in its own right or the share may accrue under the Civil Code.

Can a nonmarital great-grandchild represent a parent?

Potentially, yes. Aquino v. Aquino recognizes that marital and nonmarital children may inherit from direct ascendants by representation. Filiation, the proper branch, and the remaining succession rules must still be proved and applied.

Does an extrajudicial settlement defeat an omitted great-grandchild’s claim?

Not automatically. Rule 74 states that the settlement is not binding on a person who did not participate or had no notice. The available remedy and deadline depend on the documents, registration, possession, alleged fraud, subsequent transfers, and other facts.

Must the estate be settled before an heir has rights?

Successional rights are transmitted from the moment of death, but heirship, the net estate, and the exact property or share belonging to each heir may still require extrajudicial or judicial settlement. An heir should not assume ownership of a particular parcel before partition.
