Quick answer

An heir’s right generally begins at the moment of the decedent’s death, but the heir does not automatically become entitled to take a particular house, account, vehicle, or parcel of land. The estate must first be identified, the deceased’s property regime settled, valid debts and taxes paid, any will probated, and the remaining net estate divided among the persons legally entitled to inherit.

A will cannot freely disregard every family member. Philippine law reserves a legitime, or minimum protected share, for compulsory heirs. If there is no valid will—or the will does not dispose of the entire estate—the Civil Code’s rules on intestate succession determine who inherits and in what proportions.

Never divide, sell, withdraw, or retitle estate property based only on a family list or verbal agreement. The result depends on the validity of the marriage and will, proof of filiation, prior deaths and renunciations, the property regime, lifetime donations, debts, and the exact relatives who survived the decedent.

What passes to the heirs

Inheritance includes the deceased’s property, transmissible rights, and obligations that are not extinguished by death. Liability does not ordinarily require an heir to pay estate debts beyond the value of the property received.

The right to succession is transmitted upon death under Articles 774–777 of the Civil Code. Until partition, multiple heirs generally own the estate in common, subject to the payment of debts. Each heir has an undivided hereditary interest—not automatic ownership of whichever asset that heir occupies or possesses.

The estate is not necessarily everything registered in the deceased’s name. Before shares are computed, determine:

which assets were exclusively owned by the deceased;
which assets belonged to the absolute community or conjugal partnership;
which assets were co-owned with another person;
whether property was validly donated or transferred during life;
which debts and charges are enforceable against the estate; and
whether property claimed as part of the estate actually belongs to someone else.

If the deceased was married, the surviving spouse’s own share in community or conjugal property must first be separated. Only the deceased spouse’s portion enters the hereditary estate. That property share is distinct from the surviving spouse’s inheritance.

Who may inherit

A person may inherit through:

Testamentary succession—under a valid will;
Legal or intestate succession—under the order fixed by law; or
Mixed succession—partly under a will and partly under intestacy.

The heir must be alive or otherwise legally capable of succeeding when succession opens. A child already conceived at the time of death may acquire rights subject to the Civil Code’s rules on birth and civil personality.

A person may be excluded for a statutory cause of incapacity or unworthiness, such as specified serious acts against the decedent. These grounds are technical and fact-dependent; family disapproval, estrangement, or failure to visit is not by itself enough.

Compulsory heirs and the legitime

Article 887 of the Civil Code identifies the principal compulsory heirs:

legitimate children and descendants;
in their absence, legitimate parents and ascendants;
the surviving legal spouse; and
illegitimate children, subject to the governing provisions of the Civil and Family Codes.

A legally adopted child generally has the status and succession rights granted by adoption law in relation to the adopter. The adoption decree and the law in force when relevant should be examined, particularly when succession through biological or adoptive relatives is disputed.

A cohabiting partner who was never legally married to the deceased is not a compulsory heir merely because of the relationship’s length. That partner may still own property personally, prove a co-ownership interest, receive property under a valid will, or assert another lawful claim. Those are ownership or testamentary questions, not automatic spousal inheritance.

The legitime is protected

The legitime is the portion of the estate the testator cannot freely dispose of because the law reserves it for compulsory heirs.

As general starting points:

Legitimate children and descendants collectively have a legitime of one-half of the hereditary estate.
If there are no legitimate descendants, legitimate parents or ascendants generally have a legitime of one-half, subject to reduction when they concur with a surviving spouse.
A surviving spouse’s legitime varies according to the other compulsory heirs who survive.
Under Article 176 of the Family Code, the legitime of each illegitimate child is one-half of the legitime of a legitimate child.

These fractions cannot safely be applied in isolation. The shares interact, and the disposable portion may shrink when several classes concur. Lifetime donations that must be brought into account may also affect the computation.

Legitimate and illegitimate children inherit directly from their parent

Both legitimate and illegitimate children are compulsory heirs of their own parent. An illegitimate child’s use of the mother’s surname—or permitted use of the father’s surname—does not by itself decide filiation or the amount inherited. The controlling question is whether filiation is legally established under the applicable rules.

Succession between an illegitimate child and other legitimate relatives of the parent involves additional restrictions under Article 992. The Supreme Court has repeatedly treated this “iron curtain” rule as a serious limitation in intestate succession. Because its application can turn on the precise family line and right of representation, it should not be decided from a family tree alone. See the Supreme Court’s discussion in Aquino v. Aquino, G.R. Nos. 208912 and 209018.

What happens when there is a will

A will governs only after it has been proved and allowed in probate. A private agreement that the signature “looks genuine” does not replace probate. Under Article 838 of the Civil Code and Rules 75–76 of the Rules of Court on Special Proceedings, no will passes property unless allowed by the proper court.

Probate primarily determines whether the will was executed with the legal formalities and whether the testator had the required capacity and freedom. Questions about impaired legitimes, invalid conditions, ownership of particular assets, or excessive gifts may require further adjudication.

A will cannot simply cut off a compulsory heir

A compulsory heir may be disinherited only:

in a will;
for a cause expressly recognized by law; and
with the legal cause stated in the will.

If the heir denies the cause, the persons benefiting from the disinheritance may have to prove it. A vague statement such as “for personal reasons,” or a cause not listed by law, ordinarily does not validly remove the heir’s legitime. The Supreme Court explains these requirements in Dy Yieng Seangio v. Reyes, G.R. Nos. 140371–72.

Omission is not always valid disinheritance

Preterition generally occurs when a compulsory heir in the direct line is totally omitted from the will without express disinheritance and receives nothing by devise, legacy, or advance. Under Article 854, preterition annuls the institution of heirs, while devises and legacies remain effective only insofar as they are not excessive. It does not automatically mean that every clause of the will disappears. See Heirs of Policronio M. Ureta Sr. v. Heirs of Liberato M. Ureta, G.R. No. 254695.

If a compulsory heir received less than the legitime, the usual issue is completion of the deficient legitime rather than preterition.

What happens when there is no valid will

Intestacy applies when there is no will, the will is invalid, the institution of heirs fails, or the will leaves part of the estate undisposed of.

The following are simplified common situations. “Estate” here means the net hereditary estate after resolving ownership, the marital property regime, debts, charges, and applicable adjustments.

Surviving relatives	General intestate result
Legitimate children only	They inherit in equal shares, subject to representation where applicable.
Legitimate children and surviving spouse	The spouse generally receives a share equal to that of one legitimate child.
Legitimate and illegitimate children	Each illegitimate child generally receives one-half of the share of each legitimate child, subject to the estate being sufficient and any concurring spouse’s share.
Legitimate children, illegitimate children, and surviving spouse	The spouse generally receives a share equal to one legitimate child; each illegitimate child generally receives half of a legitimate child’s share.
Illegitimate children and surviving spouse, with no legitimate descendants or ascendants	The spouse generally receives one-half and the illegitimate children collectively receive one-half.
Legitimate parents or ascendants only, with no descendants	The nearer ascendants inherit under the statutory rules.
Legitimate parents or ascendants and surviving spouse	The ascendants collectively generally receive one-half and the spouse one-half.
Legitimate ascendants, illegitimate children, and surviving spouse	As a general rule, ascendants receive one-half, illegitimate children one-fourth, and the spouse one-fourth.
Surviving spouse only	The spouse generally inherits the estate, subject to special rules such as certain marriages celebrated in articulo mortis.
Surviving spouse with brothers, sisters, nephews, or nieces, and no descendants or ascendants	The spouse generally receives one-half; the qualifying collateral relatives receive the other half under the applicable rules.
No descendants, ascendants, illegitimate children, or spouse	Brothers and sisters and their qualifying children may inherit; more remote collateral relatives may follow within the statutory limit.
No person entitled to inherit	The estate passes to the State under the rules on escheat.

This table is not a substitute for a computation. Full-blood and half-blood siblings do not always receive the same amount. Nephews and nieces may inherit by representation or in their own right depending on who survives. Nearer relatives generally exclude more remote relatives, except where representation is legally allowed.

Representation, renunciation, and prior death

Representation allows a qualified descendant or collateral relative to step into another person’s place and take the share that person would have received. It operates only in situations allowed by law, commonly involving prior death, incapacity, or disinheritance.

A person who simply renounces an inheritance generally cannot be represented on that basis. The renounced portion passes according to the rules on intestacy, accretion, substitution, or legitime, depending on the situation.

Acceptance or repudiation generally relates back to the moment of death. Repudiation must comply with Article 1051 of the Civil Code: it must be made in a public or authentic instrument or by petition presented to the court handling the estate. An heir should not sign a waiver, quitclaim, extrajudicial settlement, or deed of sale without understanding whether it renounces the whole inheritance, transfers only a hereditary share, or conveys a particular asset.

An heir cannot sell the entire property alone

Before partition, an heir may generally deal only with that heir’s undivided hereditary interest. One co-heir cannot validly sell the other heirs’ shares without authority.

A deed describing an entire parcel as exclusively owned by one heir may bind only the seller’s eventual share, depending on the facts and legal requirements. Registration does not necessarily cure the exclusion of another heir. Likewise, long possession by one relative does not automatically erase the rights of the others, although clear repudiation of the co-ownership, notice, prescription, laches, or adverse possession may become relevant in a particular case.

An extrajudicial settlement is not binding on an heir who neither participated nor had notice, as Rule 74 expressly provides. The available remedy and deadline nevertheless depend on the deed, registration, fraud, possession, notice, and relief sought. Delay is risky.

How an estate is settled

Extrajudicial settlement

The heirs may settle without obtaining letters of administration under Section 1, Rule 74 only when:

the decedent left no will;
the decedent left no debts, or the Rule’s presumption concerning debts applies;
all heirs are of age, or minors are properly represented by duly authorized judicial or legal representatives; and
all persons whose participation is required agree.

The division must be made in a public instrument and, when real property is involved, filed with the Register of Deeds. The settlement must be published in a newspaper of general circulation in the manner required by Rule 74. Publication does not replace the participation or actual protection of an omitted heir.

The Rules presume that the deceased left no debts if no creditor petitions for letters of administration within two years after death. This is not permission to conceal a known debt. Distributees may remain answerable within the framework of Rule 74, and a bond or annotation may be required to protect affected persons.

If there is only one heir, an affidavit of self-adjudication may be appropriate if all legal requirements are present.

Judicial settlement

Court proceedings are ordinarily necessary when:

a will must be probated;
the heirs dispute identity, filiation, shares, ownership, or administration;
a qualified heir refuses to participate;
there are unresolved debts or creditor claims;
minors or incapacitated persons are not adequately represented;
estate assets require preservation or court-authorized disposition; or
extrajudicial settlement is otherwise unavailable or unsafe.

Venue generally lies in the proper court of the province where the Philippine resident decedent lived at death. If the decedent was not a Philippine resident, venue may lie where estate property is located, subject to Rule 73.

A declaration of heirship is ordinarily obtained in the proper estate proceeding, not incidentally in an unrelated ordinary case. The Supreme Court discusses the general rule and its context in Heirs of Ypon v. Ricaforte, G.R. No. 232579.

Creditor deadlines in court proceedings

After letters testamentary or of administration are issued, the court directs creditors to file claims. The period fixed in the notice must be at least six months but not more than twelve months from the first publication. Contract claims, funeral and last-illness expenses, and money judgments covered by Rule 86 generally must be presented within that period or risk being barred, subject to the Rule’s limited exceptions.

Do not confuse this court-set claims period with the two-year provisions governing certain Rule 74 liabilities or with tax deadlines.

Estate tax and transfer requirements

Inheritance rights and estate tax compliance are related but separate. Paying tax does not by itself prove who the heirs are, cure an invalid will, or settle ownership disputes.

For deaths covered by the current National Internal Revenue Code rules introduced by the TRAIN Law:

estate tax is generally 6% of the net estate;
the estate-tax return is generally due within one year from death;
the Commissioner may grant a reasonable extension to file, not exceeding 30 days, in meritorious cases;
when payment by the due date would impose undue hardship, an approved extension to pay may be available within the statutory limits; and
installment payment may be allowed under the statutory conditions when available cash is insufficient.

Late filing or payment can result in additions to tax and interest. Rules depend on the date of death, because the applicable tax law is generally the law in force at that time. Do not assume a past estate-tax amnesty remains open.

Consult the BIR’s current Estate Tax guidance and Certificate Authorizing Registration checklist before filing. The revenue district, forms, documentary requirements, payment channel, and electronic Certificate Authorizing Registration process should be confirmed for the particular estate.

After tax clearance, real property still requires the proper settlement instrument or court order, local transfer-tax compliance, and registration with the Register of Deeds. Other assets may have separate bank, corporate, vehicle-registration, insurance, or agency requirements.

Evidence to preserve immediately

Secure originals and certified copies where appropriate:

PSA death certificate;
the original will, codicils, envelopes, and related execution records;
PSA birth and marriage certificates and adoption or legitimation records;
documents proving filiation or continuous possession of status;
land titles, tax declarations, deeds, surveys, and real-property tax receipts;
bank, investment, pension, insurance, corporate, and loan records;
vehicle registrations and proof of valuable personal property;
marriage settlements and records showing the marital property regime;
contracts, mortgages, judgments, receipts, funeral expenses, and evidence of debts;
prior donations, advances, waivers, partitions, and estate settlements;
communications showing possession, collection of rent, exclusion of heirs, or threatened sale; and
photographs and an inventory of estate property.

Notify relevant banks and registries of the death through proper channels. Do not access the deceased’s online accounts by impersonation or use a power of attorney after death; an ordinary power of attorney terminates upon the principal’s death.

Practical steps for an heir

Obtain the death certificate and preserve the original will. Anyone holding a will should not hide, alter, or destroy it.
Build a verified family tree. Include all children, marriages, adopted children, deceased descendants, parents, siblings, and potential representatives. Use civil-registry and court records, not memory alone.
Inventory and secure the assets. Record who holds each title, key, passbook, device, vehicle, or rental payment. Preserve the property without secretly distributing it.
Determine the property regime. Separate the surviving spouse’s property before computing the estate.
List debts, taxes, expenses, and lifetime transfers. Do not divide only the visible assets while ignoring liabilities or donations relevant to legitimes.
Choose the correct settlement procedure. Probate a will. Use extrajudicial settlement only if every Rule 74 condition is met. Otherwise seek judicial settlement or partition as appropriate.
Compute shares using the complete survivor combination. Confirm filiation, representation, disinheritance, renunciation, and prior donations before signing.
Complete tax and registration requirements. Obtain the required BIR clearance and update the relevant registries and asset records.
Keep a full accounting. Anyone collecting rents, withdrawing authorized funds, or managing estate property should document every receipt and expense for all interested persons.

Common mistakes

Treating property registered to the deceased as entirely part of the estate without first liquidating the marital property regime.
Assuming the eldest child, the child who paid funeral expenses, or the relative holding the title automatically owns the property.
Excluding an illegitimate or adopted child without examining legal proof of status and filiation.
Treating a live-in partner as a legal spouse—or assuming the partner has no property claim at all.
Dividing property under an unprobated will.
Believing a compulsory heir can be disinherited through a letter, oral statement, family feud, or barangay document.
Signing an extrajudicial settlement that does not identify every heir.
Publishing a settlement and assuming publication cures an omitted heir’s absence.
Selling a specific estate asset before partition without the required consent or authority.
Withdrawing bank funds using the deceased’s ATM card, PIN, or expired authority.
Confusing payment of estate tax with final settlement of heirship and ownership.
Waiting because “inheritance never expires.” Particular actions may be lost through prescription, laches, adverse possession, a final court order, or transfer to an innocent third party.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

property is about to be sold, mortgaged, demolished, withdrawn, or transferred;
an heir was omitted from a deed, will, tax filing, or title;
someone is concealing the original will or estate assets;
signatures may be forged or the deceased allegedly signed while incapacitated;
filiation, adoption, marriage validity, or legitimacy is disputed;
a minor or incapacitated heir is involved;
a creditor deadline or estate-tax deadline is running;
the estate has foreign heirs, foreign assets, business interests, or private land involving a non-Filipino;
there are conflicting titles or third-party ownership claims;
an heir is being pressured to waive rights; or
violence, coercion, document destruction, or unlawful entry is threatened.

Foreign nationality does not automatically prevent inheritance. Article XII, Section 7 of the 1987 Constitution recognizes hereditary succession as an exception to the restriction on transfers of private land, but the scope of “hereditary succession,” the mode of acquisition, and later disposition should be checked carefully.

Frequently asked questions

Can a parent leave everything to only one child?

Not if doing so impairs the legitimes of other compulsory heirs. The favored child may keep only what the law permits after the protected shares and relevant lifetime donations are properly computed.

Does an illegitimate child inherit from the father?

Yes, from the child’s own father if filiation is legally established. The child is a compulsory heir, but the share is governed by Article 176 of the Family Code and the applicable concurrence rules.

Can a child be disinherited for disrespect or abandonment?

Only conduct falling within a statutory cause, properly stated in a will and proved when contested, can support disinheritance. Ordinary family conflict or a conclusory accusation is insufficient.

Does the surviving spouse automatically own half of every asset plus an inheritance share?

No. The spouse may first receive a share through the marital property regime, but that depends on the nature of the asset and governing regime. The spouse may then inherit from the deceased’s separate share. The two calculations must not be combined casually.

Can one heir live in the family home without paying the others?

Possession by one co-heir is not automatically unlawful, but exclusive use, rent, reimbursement, preservation expenses, and accounting depend on consent and circumstances. One co-heir should not exclude the others or treat the home as solely owned before partition.

Can heirs agree on unequal shares?

After identifying all heirs and satisfying legitimes, taxes, debts, and protections for minors or incapacitated persons, heirs may in some situations partition differently or transfer their interests. The document’s legal effect—partition, donation, sale, or waiver—must be clear because taxes and formalities differ.

Can an heir refuse an inheritance?

Yes, but repudiation must follow the formal requirements of Article 1051. It should be evaluated carefully because it is generally indivisible and irrevocable once validly made, subject to the Civil Code’s limited grounds for challenge.

Is a notarized extrajudicial settlement always valid?

No. Notarization does not cure a will, unpaid debts, lack of authority, fraud, incapacity, missing heirs, or failure to meet Rule 74’s conditions.

Must every estate go to court?

No. A qualifying intestate estate may be settled extrajudicially. A will, disagreement, unresolved debt, inadequate representation, or contested heirship commonly requires court involvement.

When do heirs become owners?

Successional rights pass at death, but they remain subject to estate debts, taxes, administration, the rights of other heirs, and partition. Before partition, an heir ordinarily owns an undivided interest rather than a chosen asset.
