Quick answer

Under Philippine law, an heir’s right to inherit generally arises at the moment of the decedent’s death, but the amount actually received depends on several questions: whether there is a valid will, who the surviving relatives are, whether the deceased was married, what property actually belongs to the estate, what debts and taxes must first be paid, and whether any heir is represented by descendants, disinherited, incapacitated, or has renounced the inheritance. The Civil Code recognizes testamentary succession, intestate succession, and a combination of the two. (Lawphil)

A person cannot always give away the entire estate by will. Certain compulsory heirs are protected by a legitime—a portion of the hereditary estate reserved by law. These may include children and descendants, parents or ascendants in appropriate cases, the surviving legal spouse, and illegitimate children whose filiation is established. (eLibrary)

If there is no effective will, the Civil Code determines who inherits and in what proportions. The answer is therefore not simply “the children divide everything” or “the surviving spouse gets half.” The correct computation depends on the combination of heirs who survived the deceased.

Start with the estate, not the family tree

Before computing anyone’s inheritance, determine what property actually belongs to the deceased.

Inheritance consists of the property, transmissible rights, and obligations of the deceased. Where spouses owned property under the absolute community or conjugal partnership regime, the entire community or conjugal property does not automatically become the inheritance of the deceased spouse. The marital property regime must first be liquidated. The surviving spouse receives the share that already belongs to him or her under the property regime; only the deceased spouse’s resulting share enters the hereditary estate and is then divided among the heirs. (Lawphil)

This distinction matters. Suppose a parcel of land was community property. The surviving spouse may first own a portion because of the liquidation of the marital property regime and may then inherit an additional portion from the deceased spouse’s estate. The first is an ownership or marital-property share; the second is an inheritance share.

The estate must also answer for valid debts and charges before the net distributable inheritance is finally determined. Where several heirs exist, the estate remains owned in common by them before partition, subject to payment of the deceased’s debts. (eLibrary)

Who are compulsory heirs?

A compulsory heir is a person for whom the law reserves a legitime. Under the Civil Code, read together with the Family Code and subsequent laws, the principal categories are legitimate children and descendants; legitimate parents and ascendants when there are no legitimate descendants entitled to exclude them; the surviving legal spouse; and illegitimate children whose filiation is legally established. (eLibrary)

A compulsory heir is different from a person who merely may inherit when there is no will. Brothers, sisters, nephews, nieces, and more remote collateral relatives, for example, can inherit in certain intestate situations but are generally not compulsory heirs. (eLibrary)

For adoptions governed by Republic Act No. 11642, the adoption creates legitimate filiation, and the adopter and adoptee have reciprocal succession rights without distinction from legitimate filiation. The law also generally severs the adoptee’s legal ties with biological parents, except where the biological parent is the spouse of the adopter. The law applicable to a particular adoption should nevertheless be checked because the date and nature of the adoption can matter. (Lawphil)

Legitimate and illegitimate children both have inheritance rights

Being born outside marriage does not mean that a child has no inheritance rights.

Article 176 of the Family Code provides that the legitime of each illegitimate child is one-half of the legitime of a legitimate child, while retaining the other applicable Civil Code rules on succession. Filiation, however, must be established. Articles 172 and 175 of the Family Code recognize specified forms of proof of filiation, including civil-registry records, admissions of filiation in qualifying documents, and other legally permitted evidence depending on the circumstances. (Lawphil)

A major development concerns grandchildren and other direct descendants. In Aquino v. Aquino, the Supreme Court held that Article 992’s so-called “iron curtain” does not prevent a nonmarital child from inheriting from a direct ascendant by right of representation. The Court adopted an interpretation allowing children, regardless of the circumstances of birth, to represent their parent in inheriting from a direct ascendant such as a grandparent. Article 992 still has significance in intestate succession when inheritance is claimed in one’s own right, so cases involving relatives beyond the direct line require careful analysis. (eLibrary)

What happens if there is a will?

A will does not automatically allow a testator to disregard compulsory heirs.

The legitime is the portion that the law reserves for compulsory heirs. For legitimate children and descendants, for example, the collective legitime is generally one-half of the hereditary estate, subject to the concurrent rights of the surviving spouse and illegitimate children. Different formulas apply when the surviving compulsory heirs are parents or ascendants, a spouse, illegitimate children, or combinations of these persons. (Lawphil)

The portion remaining after all legitimes have been satisfied is generally called the free portion or disposable portion. A testator may ordinarily dispose of that part in favor of persons capable of inheriting.

If a compulsory heir receives less than the legitime due, that heir may demand completion of the legitime. Testamentary dispositions that invade a compulsory heir’s legitime may be reduced to the extent necessary. A total omission of a compulsory heir in the direct line can also amount to preterition, with consequences different from an ordinary deficiency in the legitime. (Lawphil)

A handwritten document called a “last will” is also not automatically effective merely because relatives agree that the deceased wrote it. Under Rule 75, no will passes real or personal property unless it is proved and allowed by the proper court. Probate therefore remains necessary even where family members initially do not contest the will. (Lawphil)

Can a parent simply disinherit a child?

Not merely because of family conflict, estrangement, disappointment, or a declaration that “you will get nothing.”

Disinheritance of a compulsory heir must be made through a will, must specify a cause recognized by law, and the cause must fall within the statutory grounds applicable to that type of heir. The Civil Code contains separate grounds for disinheriting children or descendants, parents or ascendants, and a spouse. If the disinherited heir denies the stated cause, the burden of proving its truth falls on the heirs who rely on the disinheritance. An invalid disinheritance cannot simply erase the protected legitime. (Lawphil)

This is why an affidavit, family meeting, text message, Facebook post, deed stating that a child is “disowned,” or a verbal declaration ordinarily cannot substitute for the statutory requirements for disinheritance.

What happens when there is no valid will?

When a person dies without an effective will, the Civil Code’s rules on legal or intestate succession determine the heirs. As a general principle, the nearer relative excludes the more remote relative, subject to the right of representation where the law allows it. (Lawphil)

The following table illustrates common situations. It assumes a Filipino decedent, no effective will, and a net estate already determined after the applicable property-regime liquidation and estate obligations.

Survivors	General intestate rule
Legitimate children, no surviving spouse	Children inherit in equal shares.
Surviving spouse and legitimate children	The spouse receives the same share as each legitimate child.
Surviving spouse and illegitimate children, without legitimate descendants or ascendants	The spouse receives one-half; the illegitimate children collectively receive the other half.
Legitimate parents or ascendants and surviving spouse, without descendants	The spouse receives one-half and the legitimate parents or ascendants receive the other half.
Legitimate ascendants and illegitimate children, without a spouse	Each class collectively receives one-half.
Legitimate ascendants, surviving spouse, and illegitimate children	Ascendants receive one-half; spouse one-fourth; illegitimate children collectively one-fourth.
Surviving spouse plus brothers, sisters, nephews, or nieces, with no descendants, ascendants, or illegitimate children	The spouse generally receives one-half and the qualifying collateral relatives the other half.
Illegitimate children only, with no descendants or ascendants having preferential rights and no spouse	They may inherit the entire estate under the applicable intestate rules.

These rules come from Articles 978 onward of the Civil Code, including Articles 980, 988, 991, and 995 to 1001. The Supreme Court has repeatedly applied the rule that, when a surviving spouse concurs with legitimate children, the spouse takes the same intestate share as each child. (Lawphil)

Mixed families require additional computation. When a surviving spouse, legitimate children, and illegitimate children all concur, the spouse generally takes a share equivalent to that of a legitimate child, while the law gives each illegitimate child the proportion applicable to illegitimate filiation. The actual fractions depend on the number and classification of the surviving heirs. (Lawphil)

Rules can also differ where the deceased himself or herself was an illegitimate child, where half-blood siblings are involved, or where representation operates. An inheritance percentage should therefore not be computed from one family relationship in isolation.

When do grandchildren inherit?

Grandchildren do not automatically divide the estate equally with every surviving child of the deceased.

One important mechanism is representation. Representation places the representative in the position and degree of the person represented. In the direct descending line, if a child who would have inherited has already died or cannot inherit in a situation where representation is legally available, that child’s descendants may take the share that would have gone to the represented person. The division is by family branch, or per stirpes, rather than automatically per capita among all grandchildren. (eLibrary)

For example, if a decedent had two children, A and B, but A died earlier leaving two children while B remains alive, the two grandchildren representing A ordinarily divide A’s branch share between themselves; they do not each receive the same share as B.

The precise reason why the intermediate heir did not inherit matters. Representation does not operate identically in every case of death, incapacity, disinheritance, and voluntary repudiation.

Does a live-in partner automatically inherit?

Not merely because the couple lived together for many years.

Intestate rights given to a “widow” or “widower” refer to the legally recognized surviving spouse. The Supreme Court has held that long separation in fact and a later relationship with another partner do not by themselves erase an existing valid marriage or transform the later partner into the legal surviving spouse. (eLibrary)

A cohabiting partner may nevertheless have ownership rights over property acquired during the relationship under Articles 147 or 148 of the Family Code, depending on the parties’ circumstances and contributions. Those property rights must be distinguished from inheritance rights. A partner might also be named in a valid will when legally permissible and subject to the rights of compulsory heirs and other statutory restrictions. (Lawphil)

Can brothers, sisters, nephews, or nieces inherit?

Yes, but usually only after relatives with higher intestate priority have been considered.

If there are no descendants, ascendants, illegitimate children, or surviving spouse entitled to exclude them, qualifying collateral relatives may inherit. Brothers and sisters of the full blood generally share equally. Where full-blood and half-blood siblings concur, a full-blood sibling is generally entitled to twice the share of a half-blood sibling. Nephews and nieces can inherit in situations where representation is allowed. Other collateral relatives may inherit within the statutory limits, but intestate succession does not extend beyond the fifth degree in the collateral line. If nobody legally entitled to inherit exists, the State succeeds under the Civil Code. (Lawphil)

What rights do co-heirs have before partition?

Before partition, the heirs do not ordinarily own physically identified pieces of every estate property. Instead, where there are two or more heirs, they own the hereditary estate in common, subject to the estate’s obligations. A co-heir may deal with his or her undivided hereditary interest, but cannot validly dispose of the shares belonging to the other heirs. (Lawphil)

Each co-heir generally has a right to seek partition. Income, rents, fruits, necessary expenses, and damage to estate property may also have to be accounted for when the estate is divided.

There is another important protection when a co-heir sells hereditary rights to an outsider before partition. Article 1088 allows the other co-heirs, upon the statutory conditions, to be subrogated to the purchaser’s rights by reimbursing the purchase price within one month from written notice of the sale by the selling heir. (eLibrary)

That short period makes prompt legal advice important when an inherited share has been sold to a stranger.

Can an heir refuse an inheritance?

Yes. Acceptance or repudiation of an inheritance is voluntary, but the law prescribes consequences and formalities.

Repudiation must be made in a public or authentic instrument or through a petition presented to the court handling the estate proceeding. A parent or guardian cannot simply renounce a minor’s inheritance; judicial authorization is required for repudiation on behalf of a minor or incapacitated heir. Acceptance or repudiation, once validly made, is generally irrevocable except in the circumstances recognized by law. (Lawphil)

An heir should also be careful about saying that he “waives his share in favor of” a particular sibling. Depending on its form, a supposed waiver in favor of selected co-heirs may legally amount to acceptance followed by an assignment or transfer, which can have different civil and tax consequences.

How an estate is actually settled

The appropriate settlement procedure depends on the estate.

If there is a will, probate is required. The Rules of Court state that a person who has custody of the will must, within 20 days after learning of the testator’s death, deliver it to the court having jurisdiction or to the named executor. A named executor is likewise subject to the corresponding 20-day rule for presenting the will and indicating acceptance or refusal of the trust. (Lawphil)

If there is no will and no debts, Rule 74 permits extrajudicial settlement when all heirs are of age or any minors are represented by duly authorized judicial or legal representatives. Multiple heirs may execute a public instrument of extrajudicial settlement; a sole heir may use an affidavit of self-adjudication. The rule also requires filing with the Register of Deeds when applicable, the prescribed bond covering personal property, and publication in a newspaper of general circulation in the manner stated by Rule 74—once a week for three consecutive weeks. Importantly, an extrajudicial settlement does not bind a person who did not participate in it or had no notice of it. (Lawphil)

Where there is a genuine dispute over heirs, a contested will, unresolved debts, disagreement over partition, questions involving representation or filiation, or other circumstances making an extrajudicial settlement inappropriate, judicial estate proceedings may be necessary.

Important deadlines and time-sensitive rules

Several different periods may affect an estate, and they should not be confused with one another.

Under the Family Code, if a marriage ends by death and no judicial estate proceeding is commenced, the surviving spouse must liquidate the terminated absolute community or conjugal partnership within six months from the death. After that period, a disposition or encumbrance involving property of the unliquidated terminated community or partnership is void under Articles 103 and 130. (Lawphil)

For deaths governed by the present estate-tax regime, BIR Form No. 1801 is generally filed within one year from the decedent’s death. BIR guidance states that a reasonable extension of up to 30 days to file may be granted in meritorious cases. The TRAIN-era regulations impose estate tax at 6% of the net taxable estate, subject to the deductions and rules prescribed by tax law. (Bir CDN)

Rule 74 also provides a two-year period after settlement and distribution during which specified remedies may be pursued against the bond or estate where an heir or another person was unduly deprived of lawful participation or estate debts remain unpaid. The rule contains special protection for certain persons under disability. This two-year rule should not be assumed to be a universal prescription period for every inheritance dispute; the applicable period depends on the particular claim, the nature of the property and transaction, fraud or notice issues, and other facts. (Lawphil)

Practical steps for an heir

Secure the civil-status records. Obtain the death certificate and the birth, marriage, adoption, or other records needed to establish the family relationships and filiation of the possible heirs.
Locate the original will, if any. Do not assume that a photocopy, unsigned draft, or family understanding substitutes for probate.
Build a complete asset-and-liability inventory. Include land titles, condominium certificates, tax declarations, vehicles, bank accounts, shares, business interests, receivables, loans, mortgages, and other known obligations.
Determine the marital property regime first. Separate the surviving spouse’s ownership share from the property that actually belongs to the deceased’s estate.
Identify every possible heir before signing an EJS. Include children from prior relationships, legally established illegitimate children, adopted children, descendants of predeceased children, the surviving spouse, and other relatives whose rights may become relevant.
Compute shares under the correct succession regime. Do not apply intestate percentages to an estate governed by a will, and do not assume that a will can eliminate legitimes.
Preserve estate property and income. Keep records of rentals, harvests, business income, withdrawals, taxes, repairs, and expenses while the estate remains unpartitioned.
Attend to estate-tax and registration requirements. Registered property normally cannot simply be retitled by private agreement; the BIR and relevant registries require the applicable estate-settlement and tax documents.
Do not sell the entire inherited property as if you were sole owner. Before partition, an heir generally owns only an undivided hereditary interest unless the property has already been validly adjudicated to that heir.
Get legal advice before waiving, selling, or compromising an inheritance. These acts may be difficult to reverse and can create tax, title, creditor, and family-law consequences.

Evidence worth preserving

Keep the original or certified copies of the death certificate, birth and marriage certificates, adoption records, acknowledgment or filiation documents, the original will and codicils, land titles and tax declarations, deeds of sale or donation, bank and investment records, corporate documents, loan agreements, estate-tax filings, receipts, property valuations, insurance documents, previous extrajudicial settlements, affidavits of self-adjudication, proof of publication, and correspondence among heirs.

If there is a dispute, also preserve messages concerning admissions of relationship, threats to dispose of estate property, statements about undisclosed assets, demands for accounting, notices of sales of hereditary rights, proof of rental collections, and evidence showing who has possession of original titles or estate funds.

Common mistakes that can reduce or endanger an heir’s rights

One frequent mistake is dividing the deceased’s entire marital property without first separating the surviving spouse’s property share. Another is excluding a child because the parents were not married, even though filiation can be legally proved.

Families also sometimes execute an extrajudicial settlement without identifying every heir, treat a long-term live-in partner as automatically equivalent to a legal spouse, ignore children of a predeceased heir who may inherit by representation, or rely on a private “will” without probate.

Other risky practices include allowing one heir to keep all rental income without accounting, transferring a titled property before completing tax and registration requirements, signing a general waiver without understanding whether it operates as a transfer, and assuming that the Rule 74 two-year period automatically extinguishes every omitted heir’s claim.

When legal help is urgent

Prompt legal assistance is particularly important when estate property is about to be sold or mortgaged without the consent of all persons whose rights are affected; an heir has been omitted from an EJS or affidavit of self-adjudication; signatures appear forged; the original will is being concealed or destroyed; bank funds or rental income are being withdrawn without accounting; there is a dispute over whether someone is a child, spouse, or adopted heir; a co-heir has sold hereditary rights to a stranger; an estate-tax deadline is approaching; or a court, BIR, Registry of Deeds, bank, or other institution has already issued a deadline or adverse action.

The one-month period under Article 1088 for exercising a co-heir’s statutory redemption right after written notice of a sale is a particular reason not to delay. (eLibrary)

Special rule when the deceased was a foreign national

Philippine property location does not necessarily mean that Philippine substantive succession law controls every question.

Article 16 of the Civil Code provides that the order of succession, amount of successional rights, and intrinsic validity of testamentary provisions are governed by the national law of the deceased, regardless of the nature or location of the property. Foreign-national estates therefore require conflict-of-laws analysis rather than automatic application of the Filipino heirship percentages discussed above. (Lawphil)

FAQ

Do children automatically become owners when a parent dies?

Successional rights are transmitted from the moment of death, but that does not mean each child immediately becomes exclusive owner of a particular house, lot, vehicle, or bank account. Before valid partition, co-heirs generally hold the hereditary estate in common, subject to estate debts and settlement requirements. (eLibrary)

Can a parent leave everything to only one child?

Not ordinarily if other compulsory heirs are entitled to legitimes. A will may favor one child from the disposable portion, but testamentary provisions cannot lawfully impair the legitimes of other compulsory heirs unless a valid statutory basis such as proper disinheritance applies.

Does an illegitimate child inherit from the father?

Yes, if the required filiation is established. The Family Code recognizes successional rights of illegitimate children and provides that each illegitimate child’s legitime is one-half of the legitime of a legitimate child. The exact intestate or testamentary share depends on the other heirs who survive. (Lawphil)

Can an illegitimate grandchild inherit from a grandparent?

In appropriate cases, yes, by right of representation. The Supreme Court’s 2021 Aquino v. Aquino ruling held that Article 992 does not bar such inheritance from a direct ascendant when the grandchild inherits by representation. (eLibrary)

Is a surviving spouse always entitled to half of the estate?

No. The spouse’s inheritance depends on the other surviving heirs. A spouse who concurs with legitimate children, for example, generally receives the same intestate share as each legitimate child—not automatically one-half. Separately, the spouse may already own a portion of marital property before inheritance is computed. (eLibrary)

Can siblings inherit even if there is a surviving spouse?

In a qualifying intestate situation where there are no descendants, ascendants, or illegitimate children with preferential rights, brothers, sisters, or their qualifying descendants may concur with the surviving spouse; Article 1001 generally assigns one-half to the spouse and one-half to that collateral group. (eLibrary)

Is an extrajudicial settlement enough to transfer an estate?

Only when the legal conditions for extrajudicial settlement are satisfied. Rule 74 requires, among other things, absence of a will and debts and appropriate participation or representation of the heirs. Publication and other filing requirements apply, and an EJS does not bind a person who neither participated nor had notice. Tax and registration requirements must also be completed. (Lawphil)

How long does an heir have to claim an inheritance?

There is no single deadline covering every inheritance claim. Different periods govern different remedies, including Rule 74 proceedings, challenges based on incapacity, rescission of partitions, recovery of property, fraud-related claims, and other causes of action. An heir who learns of an exclusion or disputed transfer should not wait for an assumed “general” period before seeking advice.
